Energy Conservation Program: Test Procedure for Set-Top Boxes
AGENCY: Office of Energy Efficiency and Renewable Energy, Department of
Energy.
ACTION: Notice of proposed rulemaking.
-----------------------------------------------------------------------
SUMMARY: The U.S. Department of Energy (DOE) proposes to establish a
new test procedure for set-top boxes (STBs). The proposed test
procedure describes the methods for measuring the power consumption of
STBs in the on, sleep (commonly known as standby mode), and off modes.
Further, an annual energy consumption (AEC) metric is proposed to
calculate the annualized energy consumption of the STB based on its
power consumption in the different modes of operation. DOE has
tentatively identified that the test methods described in the draft
Consumer Electronics Association (CEA) standard, CEA-2043, ``Set-top
Box (STB) Power Measurement'' are appropriate to use as a basis for
developing the test procedure for STBs. The draft CEA-2043 standard
specifies the test methods for determining the power consumption of a
STB in the on, sleep, and off modes. The proposed test procedure in
this rulemaking is primarily based on the draft CEA-2043 standard,
which was issued as an email ballot to the members of the CEA working
group developing the standard for a vote on November 27, 2012.
DATES: DOE will hold a public meeting on Wednesday, February 27, 2013,
from 9 a.m. to 4 p.m., in Washington, DC. The meeting will also be
broadcast as a webinar. See section V, ``Public Participation,'' for
webinar registration information, participant instructions, and

I. Authority and Background
Title III of the Energy Policy and Conservation Act (42 U.S.C.
6291, et seq.; ``EPCA'' or, ``the Act'') sets forth a variety of
provisions designed to improve energy efficiency. (All references to
EPCA refer to the statute as amended through the Energy Independence
and Security Act of 2007 (EISA 2007), Public Law 110-140 (Dec. 19,
2007)). Part A of Title III of EPCA (42 U.S.C. 6291-6309) established
the ``Energy Conservation Program for Consumer Products Other Than
Automobiles,'' which covers consumer products and certain commercial
products (hereafter referred to as ``covered products'').\1\ In
addition to specifying a list of covered residential and commercial
products, EPCA contains provisions that enable the Secretary of Energy
to classify additional types of consumer products as covered products.
(42 U.S.C. 6292(a)(20)) For a given product to be classified as a
covered product, the Secretary must determine that:
---------------------------------------------------------------------------
\1\ For editorial reasons, upon codification in the U.S. code,
Part B was re-designated Part A.
---------------------------------------------------------------------------
Classifying the product as a covered product is necessary or
appropriate to carry out the purposes of EPCA; and
The average annual per-household energy use by products of such
type is likely to exceed 100kWh per year. (42 U.S.C. 6292(b)(1))
Under this authority, DOE published a notice of proposed
determination (the 2011 proposed determination), that tentatively
determined that STBs and network equipment qualify as a covered product
because classifying products of such type as a covered product is
necessary or appropriate to carry out the purposes of EPCA, and the
average U.S. household energy use for STBs and network equipment is
likely to exceed 100 kilowatt-hours (kWh) per year. 76 FR at 34914
(June 15, 2011).
DOE may prescribe test procedures for any product it classifies as
a ``covered product.'' (42 U.S.C. 6293(b)) Under EPCA, the ``Energy
Conservation Program for Consumer Products Other Than Automobiles''
consists essentially of four parts: (1) Testing, (2) labeling, (3)
Federal energy conservation standards, and (4) certification and
enforcement procedures. The testing requirements consist of test
procedures that manufacturers of covered products must use (1) as the
basis for certifying to DOE that their products comply with the
applicable energy conservation standards adopted under EPCA, and (2)
for making representations about the efficiency of those products.
Similarly, DOE must use these test requirements to determine whether
the products comply with any relevant standards promulgated under EPCA.
General Test Procedure Rulemaking Process
Under 42 U.S.C. 6293, EPCA sets forth the criteria and procedures
DOE must follow when prescribing or amending a test procedure for
covered products. EPCA provides in relevant part that any test
procedure prescribed or amended under this section shall be reasonably
designed to produce test results which measure energy efficiency,
energy use or estimated annual operating cost of a covered product
during a representative average use cycle or period of use and shall
not be unduly burdensome to conduct. (42 U.S.C. 6293(b)(3))
In addition, if DOE determines that a test procedure amendment is
warranted, it must publish a proposed test procedure and offer the
public an opportunity to present oral and written comments on it. (42
U.S.C. 6293(b)(2)) Finally, in any rulemaking to amend a test
procedure, DOE must determine to what extent, if any, the proposed test
procedure would alter the measured energy efficiency of any covered
product as determined under the existing test procedure. (42 U.S.C.
6293(e)(1)) If DOE determines that the amended test procedure would
alter the measured efficiency of a covered product, DOE must amend the
applicable energy conservation standard accordingly. (42 U.S.C.
6293(e)(2))
EPCA specifies that if the Secretary determines that a test
procedure should be prescribed for a covered product, a proposed test
procedure should be published in the Federal Register and interested
persons should be provided an opportunity to present oral and written
data, views, and arguments with respect to the proposed procedure. (42
U.S.C. 6293(b)(2)) Since DOE has tentatively determined that STBs are a
covered product and a test procedure is required to determine the
energy conservation standard for this product, a test procedure
rulemaking is being undertaken to provide a test procedure to measure
the energy consumption of STBs.
In addition to proposing a test procedure to measure the energy
consumption of STBs in on mode, DOE is proposing test procedures to
measure the energy consumption of STBs in sleep mode (an industry term
that refers to standby mode) and off mode. This is consistent with EISA
2007, which amended EPCA to require DOE to implement a standby and off
mode energy consumption measurement, if technically feasible, in new or
existing test procedures that do not have this measurement. Otherwise,
DOE must prescribe a separate standby and off mode energy test
procedure, if technically feasible. (42 U.S.C. 6295(gg)(2)(A)) EISA
2007 also requires any final rule establishing or revising energy
conservation standards for a covered product, adopted after July 1,
2010, to incorporate standby mode and off mode energy use into a single
amended or new standard, if feasible. (42 U.S.C. 6295(gg)(3)(A)) DOE
recognizes that the standby and off mode conditions of operation apply
to STBs, the product covered by this proposed rule. Therefore, in
response to this requirement, DOE proposes to adopt provisions in the
test procedure to measure the energy use in standby and off mode for
STBs. Because `sleep' is the term used by industry for indicating that
a STB is in standby mode, DOE is using the term `sleep mode' to refer
to standby mode in today's NOPR. The proposed approach for measuring
the power consumption in sleep and off modes is discussed in sections
III.G.6 and III.G.7, respectively.
In June 2011, DOE published the 2011 proposed determination that
tentatively determined that STBs and network equipment meet the
criteria for covered products. 76 FR at 34914 (June 15, 2011). If DOE
issues a final determination that STBs are a covered product, it may
establish a test procedure and energy conservation standard for STBs.
To initiate this rulemaking process, DOE published a request for
information (RFI) document on December 16, 2011 (the 2011 RFI),
requesting stakeholders to provide technical information regarding
various test procedures used by industry to measure the energy
consumption of
[[Page 5078]]
STBs and network equipment. 76 FR at 78174. Such industry test
procedures included the ENERGY STAR[supreg] program's specification,
ENERGY STAR Program Requirements for Set-top Boxes, Version 3.0 (ENERGY
STAR specification),\2\ Consumer Electronics Association's (CEA)
standards ANSI \3\/CEA-2013-A \4\ and ANSI/CEA-2022,\5\ Canadian
Standards Association's (CSA) test procedure C380-08,\6\ as well as
International Electrochemical Commission's (IEC) standard IEC
62087.\7\. Id. In the 2011 RFI, DOE also solicited comments on the key
issues affecting the development of a new test procedure. Today's NOPR
has been developed based on DOE's research and analysis of existing and
draft versions of industry standards, that prescribe test procedures
for testing STBs, as well as stakeholder responses to the key issues
discussed in the 2011 RFI.

In this NOPR, DOE proposes measurement tests to determine the power
consumption of STBs in the on, sleep, and off modes. Pursuant to the
National Technology Transfer and Advancement Act of 1995 (Pub. L. 104-
113), which directs Federal agencies to use voluntary consensus
standards in lieu of Government standards whenever possible, DOE
proposes a STB test procedure that has primarily been developed from
the draft CEA-2043 \8\ standard, currently under development by a CEA
working group that includes representatives of the STB industry. This
draft standard provides the definitions, measurement criteria, and test
procedures for testing the specific modes of STBs. DOE also proposes a
method for determining the ratings of power consumption in the on,
sleep, and off modes for a given basic model of STB, which includes the
number of units that must be tested and the statistical tolerances.
Finally, DOE proposes a metric to calculate the annual energy
consumption (AEC) of the STB. DOE's proposed metric combines the rated
values of STB power consumption in each mode of operation with the
expected time spent in the respective mode. The time weightings used to
calculate the typical energy consumption (TEC) in the ENERGY STAR
specification were used as a starting point to develop the time
weightings for the AEC metric proposed in today's NOPR.

version referenced in today's NOPR was issued as an email ballot,
for vote, to the R04WG13 working group on November 27, 2012.
---------------------------------------------------------------------------
II. Summary of the Notice of Proposed Rulemaking
In this NOPR, DOE proposes: (1) A test procedure for determining
the energy consumption of STBs in the on, sleep, and off modes; (2) a
method for determining the ratings of power consumption in the on,
sleep, and off modes for a given basic model of STB; and, (3) a metric
to calculate the AEC of the STB. DOE also proposes to exclude network
equipment from the scope of this rulemaking, which is discussed in
further detail in section III.B of this NOPR.
DOE's proposed test procedure for determining the energy
consumption of the STB is largely developed from the draft CEA-2043
standard. The draft CEA-2043 standard was issued as an email ballot to
CEA's working group members for vote on November 27, 2012. The standard
specifies the definitions, measurement criteria, and the test methods
for determining the power consumption of the STB in different modes of
operation. DOE reviewed several approaches for testing the power
consumption of STBs and determined that the test procedure specified in
the draft CEA-2043 standard is representative and generates repeatable
power consumption values. This determination was made based on
discussions with industry experts as well as through DOE's internal
research and analysis. Additionally, DOE has proposed some
modifications to the test procedure specified in the draft CEA-2043
standard as discussed in sections III.D through III.G.
DOE's proposed test procedure for determining the power consumption
of a STB in on mode is comprised of two main tests: (1) An on (watch
television (TV)) test that records the power consumption when a channel
is viewed; and, (2) a multi-stream test that evaluates different
functions of multi-streaming STBs depending on its capabilities, such
as channel viewing, recording, and playback. The proposed tests for on
mode are discussed in further detail in section III.G.5 of the NOPR.
For testing the power consumption of the STB in sleep mode, DOE
developed the test procedure from the sleep mode test procedure
specified in the draft CEA-2043 standard. Sleep mode as defined in the
CEA standard meets the definition of standby mode as outlined in EISA
2007. (42 U.S.C. 6295(gg)) As discussed in Authority and Background,
section I of this NOPR, DOE proposes to use the industry term `sleep'
mode in place of standby for this test. For the sleep mode test, DOE
proposes two tests: (1) a manual sleep test in which the STB enters
sleep mode through a user action on the remote control; and, (2) an
auto power down (APD) test in which the STB automatically enters sleep
mode after a period of user inaction. For both sleep mode tests, an
average power measurement over a period of at least 4 hours and up to a
maximum of 8 hours is recorded as discussed in section III.G.6. For
testing the power consumption of the STB in off mode, DOE proposes an
average measurement over 2 minutes after the STB has been placed in off
mode. The proposed off mode measurement test is discussed in further
detail in section III.G.7.
In addition to proposing measurement tests to measure the power
consumption of the STB in the different modes of operation, DOE is
proposing a sampling plan that requires testing of at least two STBs
for each basic model, to determine the power consumption in each mode
of operation and the application of tolerances for determining the
rating of a given basic model, as discussed in further detail in
section III.H.
Finally, DOE is proposing a metric to calculate the AEC of the STB
from the rated power consumption in the on, sleep, and off modes of
operation. The proposed metric combines the rated power consumption
values of the STB in the different modes of operation into a single
metric based on the expected time spent in each mode of operation such
that it is representative of the STB's annual energy use. The time
weightings used to calculate TEC in the ENERGY STAR specification were
used as the starting point to develop the time weightings that are
proposed for the AEC metric. DOE believes that the proposed test
procedure will accurately represent the energy consumption of STBs by
capturing the AEC in on, sleep, and off modes. The AEC metric is
discussed in further detail in section III.I.
[[Page 5079]]
III. Discussion
A. Effective Date and Compliance Date of Test Procedure
If adopted, the effective date for this test procedure would be 30
days after publication of the test procedure final rule in the Federal
Register. At that time, the new metrics and any other measure of energy
consumption which depends on these metrics may be represented pursuant
to the final rule. Compliance with the new test procedure and sampling
plans for representation purposes would be required 180 days after the
date of publication of the test procedure final rule. On or after that
date, any such representations, including those made on marketing
materials, Web sites (including qualification with a voluntary or State
program), and product labels shall be based upon results generated
under the final test procedure proposed to be included in Appendix AA
to Subpart B of 10 CFR Part 430 as well as the sampling plan in 10 CFR
Part 429.
The final DOE test procedure shall be utilized or referenced by all
other organizations, such as U.S. Environmental Protection Agency (EPA)
for its ENERGY STAR specification for STBs, the California Energy
Commission (CEC) and any other state regulation providing for the
disclosure of information with respect to any measure of STB energy
consumption once the test procedure becomes effective 30 days after the
test procedure final rule publication. The final rule will supersede
any existing state test procedure for STBs to the extent the state
regulation requires testing in a manner other than that required by the
final DOE test procedure. (42 U.S.C. 6297(a)(1))
B. Products Covered by This Rulemaking
In the 2011 RFI, DOE requested comment on the scope of the STB and
network equipment test procedure rulemaking. DOE received some comments
that network equipment should not be included in the scope of the
rulemaking, and received some comments in favor of developing a Federal
test procedure for STBs. Verizon commented that DOE should not identify
network equipment as a covered product and should clarify that only
``traditional, dedicated'' STBs would be subject to any test procedure
or energy conservation standard. (Verizon, No. 0032 at p. 5) \9\ The
Consortium for Energy Efficiency (CEE) commented that they support the
development of a test procedure for STBs that accurately measures STB
energy consumption by simulating actual usage by consumers. (CEE, No.
0028 at p. 1) Further, the joint response of DISH Network L.L.C.
(DISH), EchoStar Technologies L.L.C. (EchoStar), and DIRECTV L.L.C.
(DIRECTV), commented that this rulemaking should be limited to STBs and
should not include network equipment. (DISH, EchoStar, DIRECTV, No.
0030 at p. 1) The National Cable & Telecommunications Association
(NCTA) commented that if DOE proceeded with a rulemaking, the scope of
this rulemaking should include STBs that are defined as any non-gateway
devices. (NCTA, No. 0034 at p. 43) DOE also received a comment in
support of a test procedure for network equipment. The joint comment
response of Appliance Standards Awareness Project (ASAP), American
Council for an Energy-Efficient Economy (ACEEE), and Consumer
Federation of America (CFA) encouraged DOE to continue investigating
both network equipment and STBs in order to realize energy savings for
consumers as well as other economic and environmental benefits. (ASAP,
ACEEE, CFA, No. 0025 at p. 1-5) These commenters did not recommend any
specific test method for testing network equipment but suggested that
DOE should look into existing test methods that were identified during
the development of the ENERGY STAR specification for small network
equipment.\10\ (ASAP, ACEEE, CFA, No. 0025 at p. 3)

---------------------------------------------------------------------------
Based on stakeholder feedback, DOE proposes to exclude network
equipment from the scope of this NOPR and focus exclusively on STBs.
DOE proposes that the scope of today's proposed rulemaking is to
capture the energy consumption of STBs that primarily receive and
output video content. DOE proposes to define STBs as described in
section III.D.1 below. DOE will continue to evaluate the need for a
test procedure for network equipment.
In addition to receiving comments on the overall scope of coverage
of today's NOPR, DOE received comments about the exclusion of specific
models of STBs. Sidley Austin LLP (Sidley Austin) commented that during
a meeting between DOE, AT&T, and Sidley Austin on March 7, 2012, AT&T
representatives suggested that AT&T's U-verse[supreg] receivers should
not be covered under any test procedure or energy conversation standard
rulemaking because the product already uses less power than other STBs
and does not meet the annual 100 kWh statutory threshold set by EPCA
for covered products to be regulated. (Sidley Austin LLP, No. 0024 at
p. 2) Sidley Austin further commented that AT&T's U-verse[supreg] is
one of the most energy efficient STBs on the market and is continuing
to improve its efficiency. (Sidley Austin LLP, No. 0024 at p. 2) Next,
AT&T commented that DOE should refrain from promulgating a test
procedure or energy efficiency standard for Internet Protocol TV (IPTV)
receivers because the energy use of IPTV STBs does not meet the
statutory threshold for these boxes to be regulated. (AT&T, No. 0032 at
p. 5) DOE considers that today's test procedure NOPR is applicable to
any STB, including IPTV, as defined in section III.D.1 and will address
the scope of coverage for any energy conservation standard during that
rulemaking, if required.
DOE also received several comments on the coverage of low noise
block-downconverters (LNBs), auxiliary boxes, optical network terminals
(ONTs), and standalone digital video recorders (DVRs). The Natural
Resources Defense Council (NRDC) recommended including all of these
products in the scope of this rulemaking. (NRDC, No. 0017 at p. 2) NRDC
further commented that once ONTs are installed, they are not removed
when service is terminated. If a customer switches to a service
provider that does not require an ONT, this unit could continue drawing
power without being used. (NRDC, No. 0017 at p. 2) Conversely, DISH,
EchoStar, and DIRECTV commented that LNBs should not be included in the
scope of this rulemaking. They commented that LNBs can consume varied
power in different configurations. (DISH, EchoStar, DIRECTV, No. 0030
at p. 5) Further, the outdoor unit (ODU) that consists of a receiving
dish, LNB, and radio frequency (RF) switch would need to be specified
in detail to test these units in a repeatable fashion. Finally, the
power consumption of the ODU devices varies with weather and location.
(DISH, EchoStar, DIRECTV, No. 0030 at p. 11)
Because of the complexity associated with these equipment and the
[[Page 5080]]
significant operational differences from STBs, DOE does not propose to
include LNBs, ONTs, ODUs, or other infrastructure devices that do not
directly deliver TV signals to a consumer display to be in the scope of
this rulemaking.
DOE requests comment on focusing the scope of today's rulemaking to
STBs and excluding network equipment. Further, DOE seeks additional
information and comment related to the development of a test procedure
for LNBs, ONTs, ODUs, or other infrastructure devices and the standard
configuration in which these products should be tested.
C. Industry Set-Top Box Test Procedures
While developing the proposed test procedure for STBs, DOE
researched existing and draft test procedures that measure STB energy
consumption, as discussed in the 2011 RFI. DOE received a comment from
CEA stating that it should not duplicate the private sector's
development of a consensus standard test procedure for measuring the
power consumption of STBs. (CEA, No. 0031 at p. 3) DOE agrees with CEA
and is proposing a test procedure for STBs that is largely based on
standards accepted and developed by industry. The standards that were
reviewed to develop this test procedure NOPR include the ENERGY STAR
specification, CEA standards ANSI/CEA-2013A, ANSI/CEA-2022, the draft
CEA-2043 standard, CSA test procedure C380-08, as well as IEC standard
IEC 62087.
The ENERGY STAR specification includes a test method for
determining the power consumption of the STB in different modes of
operation. The ENERGY STAR test method provides the test setup, test
conduct, initialization requirements, and test procedures for testing
the STB in many different modes of operation. These include, in the on
mode: watching TV, recording to a DVR and removable media, and playing
back recorded content from a DVR and removable media. In the sleep
mode, the test procedures include: sleep mode, APD, and deep sleep.
Finally, the ENERGY STAR test method also includes a method for testing
a STB that has multi-room capability. The ENERGY STAR test method was
developed based on the CSA test procedure, C380-08. DOE referred to
some sections of the ENERGY STAR specification to develop today's NOPR,
which are discussed in detail in sections III.D to III.I.
The ANSI/CEA-2022 and ANSI/CEA-2013A provide an overview to
determine the power consumption of STBs in the on, sleep and off modes,
respectively. The standards do not contain detailed information about
testing and setup for the different modes of operation. As discussed,
CEA is also developing a new standard, CEA-2043, that is currently in
draft form but will supersede CEA standards ANSI/CEA-2013A and ANSI/
CEA-2022 once it is published. Therefore, DOE did not refer to ANSI/
CEA-2013A and ANSI/CEA-2022 to develop today's proposed rule; instead
it refers to the draft CEA-2043 standard.
The CSA test procedure, C380-08, specifies test conditions and
setup requirements that are also referenced in the ENERGY STAR
specification and are the same as those specified in the draft CEA-2043
standard. The C380-08 standard specifies test procedures for
determining energy consumption in the on and sleep modes of operation,
from which the ENERGY STAR specification was developed. Therefore, DOE
does not reference this CSA test procedure in the NOPR because the
information specified in the CSA test procedure is also included in the
ENERGY STAR specification.
IEC 62087 provides specification for testing the STB at different
input signal levels and different input terminals depending on the type
of the STB. The standard provides test procedures for determining power
consumption in the on and sleep modes. In the on mode, IEC 62087
specifies tests in the play, record, and multi-function (with single
and multiple tuners) modes. In sleep mode, it specifies tests at the
active high, active low, and passive modes. DOE refers to IEC 62087 to
support some of its proposed requirements.
DOE primarily focused on the draft CEA-2043 standard to develop the
test procedure for STBs that is proposed in this NOPR. The draft CEA-
2043 standard specifies the test conditions and test setup at which
power consumption of the STB should be measured. These include the
modes of operation of the STB, test room and equipment requirements,
and measurement tests for determining the power consumption in each
mode of operation. DOE also referred to the ENERGY STAR specification
to develop some of the proposed requirements, such as the AEC metric,
that are not specified in the draft CEA-2043 standard. In review of
CEA-2043, DOE found that CEA is a leading organization that connects
consumer electronics manufacturers, retailers, and other interested
parties to develop industry accepted electronics test procedures. The
CEA Technology & Standards program is CEA's standards making body that
is accredited by ANSI.\11\ CEA-2043 is being developed under the CEA
R04 WG13 STB Energy Consumption working group, which falls under the
CEA Technology & Standards program. DOE representatives have observed
the development of CEA-2043, attended conference call meetings between
STB manufacturers and energy advocates during draft revisions, and have
been included on all notes and documentation from the CEA R04 WG13 STB
Energy Consumption working group. Today's NOPR has primarily been
developed using the draft version of the CEA-2043 standard that was
issued as an email ballot to members of the working group for a vote on
November 27, 2012. However, DOE is proposing some modifications, which
are discussed in sections III.D through III.G.

The draft version of the CEA-2043 standard was in a 30 day voting
period that ended on December 28, 2012. Once the final CEA-2043
standard is published, it will be available on CEA's Web site at http://www.ce.org/Standards/Standard-Listings.aspx. DOE requests comment on
using the draft CEA-2043 standard as the basis for today's proposed
test procedure for STBs.
D. Definitions
1. Definition of Set-Top Boxes
Because there are no statutory definitions for STBs under EPCA
currently, DOE proposes to develop a definition for STBs. Cisco
commented that defining STBs as traditional STBs would capture only
some of the ways in which video program is delivered and a broader
definition that is designed to encompass all means by which a consumer
could receive video signals from multichannel video programming
distributors (MVPD) could inadvertently bring tablet computers,
computers, gaming consoles, and smartphones under this regulation.
(Cisco Systems, Inc., No. 0027 at p. 11) DOE understands these concerns
and is proposing a definition that captures more than just traditional
STBs, while mitigating the issues associated with a broader definition
of STBs. The proposed definition would be included in 10 CFR Part 430.2
and would define STBs as ``a device combining hardware components with
software programming designed for the primary purpose of receiving
television and related services from terrestrial, cable, satellite,
broadband, or local networks, providing
[[Page 5081]]
video output using at least one direct video connection.''
DOE also proposes to include a definition for direct video
connection, in 10 CFR Part 430.2, as ``any connection type that is one
of the following: High-Definition Multimedia Interface (HDMI),
Component Video, S-Video, Composite Video, or any other video interface
that may be used to output video content.''
DOE's proposed definition of STBs is different from the definition
specified in section 4 of the draft CEA-2043 standard. That standard
defines a STB as ``a device that receives video content which is then
delivered to a display device, recording device, or client''. DOE did
not adopt CEA's definition in the NOPR because DOE believes the
definition is vague and can include such devices in the scope of this
rulemaking that are not, in fact, STBs. According to the definition
specified in the draft CEA-2043 standard, any device that can receive
video content and can deliver it to display device, recording device,
or client is a STB. Under this definition, devices such as a smartphone
could potentially be included under the scope. DOE believes these
devices should not be included because the scope of today's rulemaking
is to capture the energy use for those devices that primarily receive
and output video content. Because the primary use of a device such as a
smartphone or gaming console is not to output video content, today's
test procedure would not make adequate energy representations of these
products. DOE believes that smartphones do not meet the definition of a
STB under today's proposed definition.
DOE does not propose to use the definition specified in the draft
CEA-2043 standard. Instead, DOE developed a definition for STBs that
includes specific detail about the types of networks the device can
receive video content from and the allowable output connections for
delivering the video content. The types of networks from which content
could be received--terrestrial, cable, satellite, broadband, or local
networks--are all networks that are commonly used for STBs. In fact,
STBs are often defined by their base type functionality, which
generally includes the network type used. This information was also
included in the definition for STBs in an older draft of the CEA-2043
standard and DOE proposes to include it to add specificity to the STB
definition. Additionally, DOE's proposed definition refers to a device
that is manufactured when both the hardware components and the software
is loaded on the device such that its primary purpose is receiving and
outputting video. DOE believes it is important for the definition of a
STB to include both software and hardware because the underlying
hardware for a STB could look much like a general purpose computer, but
the software added to such hardware distinguishes the unit allowing it
to function as a STB. Further, the proposed DOE definition does not
include specific devices to which the content is delivered, while the
draft CEA-2043 definition specifies that the content is delivered to a
display device, recording device, or client. In lieu of specifying the
types of devices to which the content may be delivered, DOE's proposal
specifies the types of video connections that may be used, since, at a
minimum, a STB must deliver content to a video device. Including detail
about the direct video connections that are permissible ensures that
devices that do not primarily deliver content to a video device do not
meet the proposed definition. For example, devices that receive and
transmit information solely through a network interface and do not have
a video output would not be considered a STB under DOE's proposed
regulatory definition, but would be considered a STB if the draft CEA-
2043 standard's definition were adopted. DOE believes that today's
proposed test procedure would not make appropriate representations of
energy consumption for devices that do not provide a direct video
output, and therefore, has proposed this definition to narrow the scope
compared to the CEA-2043 standard.
Finally, to further aid in defining the scope of coverage of this
rulemaking, DOE proposes to include definitions for Component Video,
Composite Video, HDMI, and S-Video in the test procedure. These terms
are all used in the definition for direct video connection, which is
used to define STBs. DOE proposes to define these terms in section
430.2 of subpart A of 10 CFR part 430 as follows:
Component Video: Component Video is a video display interface that
meets the specification in CEA-770.3-D.
Composite Video: Composite Video is a video display interface that
uses a Radio Corporation of America (RCA) connection to transmit
National Television System Committee (NTSC) analog video.
HDMI: High-Definition Multimedia Interface or HDMI is an audio/
video interface that meets the specification in HDMI Specification
Version 1.0.
S-Video: S-Video is a video display interface that transmits analog
video over two channels: luminance and color.
For the definitions of Component Video and HDMI, DOE proposes to
incorporate by reference two industry standards that are used to define
these terms. Specifically, DOE proposes to define Component Video as a
connection that meets the requirements found in CEA-770.3-D.\12\ For
HDMI, DOE is proposing to define it as a connection that meets the
requirements found in the HDMI Specification Version 1.0.\13\ DOE
believes these industry standards provide the appropriate information
for defining the Component Video and HDMI connections and has therefore
incorporated these standards by reference in section 430.3 of Subpart A
of 10 CFR Part 430.

---------------------------------------------------------------------------
In the 2011 proposed determination, DOE proposed a definition for
STBs and network equipment as ``a device whose principal function(s)
are to receive television signals (including, but not limited to, over-
the-air, cable distribution system, and satellite signals) and deliver
them to another consumer device, or to pass Internet Protocol traffic
among various network interfaces.'' 76 FR at 34915 (June 15, 2011). DOE
received several comments about this definition from stakeholders. The
Northwest Energy Efficiency Alliance (NEEA) suggested a new definition
for STBs that accounts for the fact that these devices serve a broader
function than to simply relay TV signals. (EERE-2010-BT-DET-0040, NEEA,
No. 0006 at p. 2) AT&T and the California Investor Owned Utilities (CA
IOUs) commented that DOE should adopt the definition of STB that has
been developed by the ENERGY STAR program because it is well known by
industry. (EERE-2010-BT-DET-0040, AT&T, No. 0008 at p. 9) (EERE-2010-
BT-DET-0040, CA IOUs, No. 0011 at p. 2) Further, the Northeast Energy
Efficiency Partnerships (NEEP) commented that STBs and network
equipment should have a single definition because they perform similar
functions. (EERE-2010-BT-DET-0040, NEEP, No. 0010 at p. 2) In contrast,
the CA IOUs commented that separated definitions should be adopted for
STBs and network equipment to explicitly describe the products covered.
(EERE-2010-BT-DET-0040, CA IOUs, No. 0011 at p. 2) NCTA commented that
STBs and network equipment vary too
[[Page 5082]]
much to fit under one definition and that network equipment should be
dropped from the rulemaking. (EERE-2010-BT-DET-0040, NCTA, No. 0017 at
p. 8, 22) NRDC commented that the part of the definition that states
``the principal function(s) are to receive TV signals'' should be
expanded because STBs receive more types of signals than TV signals.
(EERE-2010-BT-DET-0040, NRDC, No. 0012 at p. 5) CEA commented that DOE
should adopt the definition that will be specified in the new CEA
standard and should compare the proposed STB definition to the Federal
Communications Commission's (FCC) definition of ``navigation device''
to avoid defining the same product category differently. (EERE-2010-BT-
DET-0040, CEA, No. 0014 at p. 3) CEA also commented that the definition
of STBs should not include a device with gateway functionality, such as
devices that terminate the service provider or IP network for multiple
devices in a home, because such a definition would combine video and
non-video related devices and would include many different products
such as networking switch, hub, Wireless-Fidelity (Wi-Fi) \14\ access
point, Ethernet extending devices, and possibly the entire category of
home automation, security and smart grid products. (EERE-2010-BT-DET-
0040, CEA, No. 0014 at p. 4) Finally, CEA, Verizon, and the
Telecommunications Industry Association (TIA) commented that the phrase
``to pass Internet Protocol traffic among various network interfaces''
should be excluded from the proposed definition as they believe the
scope of the rulemaking is to only cover video related devices. (EERE-
2010-BT-DET-0040, Verizon, No. 0015 at p. 4) (EERE-2010-BT-DET-0040,
TIA, No. 0040 at p. 4)

\14\ Wi-Fi technology allows electronic devices to use radio
waves to exchange data wirelessly over a computer network using the
Institute of Electrical and Electronics Engineers (IEEE) 802.11
standards.
---------------------------------------------------------------------------
DOE reviewed the comments it received on the 2011 proposed
determination and preliminarily concluded that it will not continue
with the definition proposed for STBs and network equipment in the 2011
proposed determination, for the following reasons. First, the intent of
the proposed definition in the 2011 proposed determination was that it
be broad enough so that it covered both STBs and network equipment.
However, as discussed in section III.B, today's proposed rule narrows
the scope of the rulemaking to cover only STBs and not network
equipment. Second, DOE believes that the definition in the 2011
proposed determination may be too broad for the purposes of the STB
test procedure rulemaking. The definition of ``principal function''
could be ambiguous; it is not explicit whether the principal function
is based on how the device is used by the consumer or how the
manufacturer intends the device to be used. Further, the definition in
the 2011 proposed determination does not explicitly state that video
content should be delivered using a direct video connection, which is
included in the definition proposed in today's NOPR. As discussed
previously, specifying that the device should deliver video content
using a direct video connection ensures that devices that do not use
this connection are excluded from the proposed definition of STB.
Therefore, DOE has proposed a new definition solely for STBs as
discussed in the above paragraph.
DOE also considered defining a STB using the base types included in
the ENERGY STAR specification. However, the ENERGY STAR definition is
more suited to differentiating product types for the purposes of
efficiency levels, which is not necessary when it comes to defining
scope of coverage for DOE's regulatory program.
In conclusion, DOE proposes to define STBs as ``a device combining
hardware components with software programming designed for the primary
purpose of receiving television and related services from terrestrial,
cable, satellite, broadband, or local networks, providing video output
using at least one direct video connection.'' DOE invites comment on
this proposed definition of STBs. In particular, DOE requests comment
about whether the proposed definition is specific enough to exclude
non-STB devices such as gaming consoles and smartphones, yet broad
enough to cover traditional STBs as well as newer STBs. DOE also
requests comment on the proposed definitions for direct video
connection, Component Video, Composite Video, HDMI, and S-Video.
2. Basic Model of an STB
In March 2011, DOE published a final rule for `Certification,
Compliance, and Enforcement for Consumer Products and Commercial and
Industrial Equipment'. 76 FR at 12422 (March 7, 2011). In this rule,
DOE codified a definition for basic model in 10 CFR Part 430.2 as
follows:
``Basic model means all units of a given type of covered product
(or class thereof) manufactured by one manufacturer, having the same
primary energy source, and which have essentially identical electrical,
physical, and functional (or hydraulic) characteristics that affect
energy consumption, energy efficiency, water consumption, or water
efficiency; and
(1) With respect to general service fluorescent lamps, general
service incandescent lamps, and incandescent reflector lamps: Lamps
that have essentially identical light output and electrical
characteristics--including lumens per watt (lm/W) and color rendering
index (CRI).
(2) With respect to faucets and showerheads: Have the identical
flow control mechanism attached to or installed within the fixture
fittings, or the identical water-passage design features that use the
same path of water in the highest flow mode.''
For today's NOPR, DOE reviewed this definition of a basic model and
has determined that the definition of basic model codified in 10 CFR
Part 430.2 is applicable to STBs. For STBs, the `identical electrical,
physical, and functional characteristics' that identify two units as
being the same basic model would also cover software download or
hardware integration. This is because hardware components and software
programming can change the functional or physical characteristics of
the box that affect energy consumption and/or energy efficiency. Thus,
in order for multiple STBs to be in the same basic model they must have
essentially the same software downloads and hardware integration.
Additionally, for today's proposed rule, DOE also believes that two STB
units are considered to be the same basic model if they have the same
multi-streaming and DVR functionality as described in section III.D.4.
DOE invites comment on the discussion of basic model as it pertains
to the STB rulemaking.
3. Manufacturer of a Set-Top Box
DOE considers today's proposed test procedure applicable to any
person that meets the definition of manufacturer under EPCA as it
relates to STBs. EPCA defines the term ``manufacture'' as ``to
manufacture, produce, assemble, or import.'' (42 U.S.C. 6291(10)) The
proposed definition of a STB itself is discussed in section III.D.1 of
the NOPR.
4. Other Definitions
For the STB test procedure NOPR, DOE proposes to define terms that
are relevant for the test procedure based on the definitions specified
in section 4 of the draft CEA-2043 standard. Of these definitions, DOE
proposes clarifying information, beyond what is provided in the draft
CEA-2043 standard, for the definitions of DVR, display device, and home
network interface (HNI). Additionally, DOE is including new
[[Page 5083]]
definitions for content provider and multi-stream. The proposed
definitions are included in section 2 (Definitions) of the proposed
Appendix AA to Subpart B of 10 CFR Part 430. All proposed definitions
are listed below, followed by a discussion of any differences from the
draft CEA-2043 standard.
Auto power down (APD): A STB feature that monitors parameters
correlated with user activity or viewing. If the parameters
collectively indicate that no user activity or viewing is occurring,
the APD feature enables the STB to transition to sleep or off mode.
Client: Any device (example: STB, thin-client STB, smart TV,\15\
mobile phone, tablet, or personal computer) that can receive content
over a home network interface (HNI).
---------------------------------------------------------------------------
\15\ A smart TV is a hybrid TV that combines internet features
into modern TVs and STBs.
---------------------------------------------------------------------------
Content provider: An entity that provides video programming
content.
Crest factor: The ratio of the peak current to the root-mean-square
(rms) \16\ current.
---------------------------------------------------------------------------
\16\ Rms current is a statistical measure of the magnitude of a
current signal. Rms current is equal to the square root of the mean
of all squared instantaneous currents over one complete cycle of the
current signal.
---------------------------------------------------------------------------
Digital video recorder (DVR): A STB feature that records TV signals
on a hard disk drive (HDD) or other non-volatile storage device
integrated into the STB. A DVR often includes features such as: Play,
Record, Pause, Fast Forward (FF), and Fast Rewind (FR). STBs that
support a service provider delivery network based ``DVR'' service are
not considered DVR STBs for the purposes of this test procedure. The
presence of DVR functionality does not mean the device is defined to be
a STB.
Display device: A device (example: TV, Computer Monitor, or
Portable TV) that receives its content directly from a STB through a
video interface (example: HDMI, Component Video, Composite Video, or S-
Video), not through a home network interface (HNI), and displays it for
viewing.
Harmonic: A component of order n of the Fourier series \17\ that
describes the periodic current or voltage (where n is an integer
greater than 1).
---------------------------------------------------------------------------
\17\ A Fourier series decomposes period functions or period
signals in terms of an infinite sum of simple oscillating functions,
such as sines and cosines.
---------------------------------------------------------------------------
High definition test stream (HD): Video content delivered to the
STB by the content provider to produce a minimum output resolution of
1280 x 720 pixels in progressive scan mode \18\ at a minimum frame rate
of 59.94 frames per second (fps) (abbreviated 720p60) or a minimum
output resolution of 1920 x 1080 pixels in interlaced scan mode at
29.97 fps (abbreviated 1080i30).
---------------------------------------------------------------------------
\18\ Progressive scan mode is a method of displaying, storing,
or transmitting moving images such that all lines in each frame are
drawn in sequence.
---------------------------------------------------------------------------
Home network interface (HNI): An interface with external devices
over a local area network (example: IEEE 802.11 (Wi-Fi), Multimedia
over Coax Alliance (MoCA) \19\, HomePNA Alliance (HPNA),\20\ IEEE
802.3,\21\ or HomePlug AV \22\) that is capable of transmitting video
content.
---------------------------------------------------------------------------
\19\ MoCA is a trade group that promotes a standard that uses
coaxial cables to connect consumer electronic products and home
networking devices. The connection allows both data communication
and the transfer of audio and video streams. It is the only home
entertainment networking standard used by all three pay TV segments,
such as, cable, satellite, and IPTV.
\20\ HPNA is an incorporated non-profit industry association of
companies that develops home networking specifications for
distributing entertainment and data over existing coaxial cables and
telephone wiring within homes.
\21\ IEEE 802.3 is a working group that develops standards for
Ethernet based local area networks.
\22\ HomePlug is an industry alliance that provides
specifications that support networking over existing home electrical
wiring. HomePlug AV is a specification that provides sufficient
bandwidth for applications such as high definition TV (HDTV) and
voice over IP (VoIP).
---------------------------------------------------------------------------
Low noise block-downconverter (LNB): A combination of low-noise
amplifier, block-downconverter and intermediate frequencies (IF)
amplifier. It takes the received microwave transmission, amplifies it,
down-converts the block of frequencies to a lower block of IF where the
signal can be amplified and fed to the indoor satellite TV STB using
coaxial cable.
Multi-stream: A STB feature that may provide independent video
content to one or more clients, one or more directly connected TVs, or
a DVR.
Outdoor unit (ODU): Satellite signal reception components
including: a receiving dish, one or more LNBs, and imbedded or
independent radio frequency (RF) switches, used to distribute a
satellite service provider network to consumer satellite STBs.
Point of deployment (POD) module: A plug-in card that complies with
the ANSI/SCTE \23\ 28 \24\ interface and is inserted into a digital-
cable-ready device to enable the decryption of services and provide
other network control functions.

Power mode: A condition or state of a device that broadly
characterizes its capabilities, power consumption, power indicator
coding, and responsiveness to input.
Principal STB function: Functions necessary for selecting,
receiving, decoding, decompressing, or delivering video content to a
display device, DVR, or client. Monitoring for user or network requests
is not considered a principal STB function.
Satellite STB: a STB that receives and decodes video content as
delivered from a service provider satellite network.
Service provider: A business entity that provides video content, a
delivery network, and associated installation and support services to
subscribers with whom it has an ongoing contractual relationship.

Standard definition test stream (SD): Video content delivered to
the STB by the content provider to produce an output resolution of 640
x 480 pixels in interlaced scan mode at minimum frame rate of 29.97 fps
(abbreviated 480i30).
Thin-client STB: A STB that can receive content over an HNI from
another STB, but is unable to interface directly to the service
provider network.
DOE proposes to incorporate by reference the industry standards
that are used in the definitions of POD and smart card. These standards
are: ANSI/SCTE 28 for the definition of POD and ISO/IEC 7816-12 for the
definition of Smart Card. These industry standards are part of the
definition provided in the draft CEA-2043 standard, and DOE believes
the standards provide necessary information to define the POD and Smart
Card plug-in cards.
The definition of DVR in the draft CEA-2043 standard is, ``a STB
feature that records TV signals on a hard disk drive (HDD) or other
non-volatile storage device. A DVR often includes features such as:
Play, Record, Pause, Fast Forward (FF), and Fast Rewind (FR). STBs that
support a service provider delivery network based ``DVR'' service are
not considered DVR STBs for the purposes of this test procedure. The
presence of DVR functionality does not mean the device is defined to be
a STB.'' The definition of DVR in the draft CEA-2043 standard does not
explicitly state that the HDD should be integrated into the STB, while
DOE's proposed definition adds the specification that the HDD or other
non-volatile storage
[[Page 5084]]
device shall be integrated into the STB. DOE has included this
information to explicitly state that this proposed rule does not
consider STBs with an external HDD as STBs with DVR capability. This
requirement is similar to the ENERGY STAR specification and has been
included in today's proposed DVR definition because external storage
devices are usually optional, and existing test procedures do not
address how to test STBs with the external HDD attached.
In today's NOPR, DOE is proposing only to test STBs with integrated
storage as a DVR. For STBs that support DVR only through an external
storage device, DOE is proposing to test these basic models as a STB
without DVR. There are currently a wide selection of external storage
devices that can be paired with a STB to support DVR functionality, and
DOE believes the choice of external storage device paired with the unit
could impact the energy consumption of the STB itself. While DOE's
preferred approach is to test the STB without DVR capabilities if they
use an external storage device, DOE did consider an alternative that
would capture this use. For testing purposes, DOE could specify the
external storage device such as the storage device that is shipped with
the STB or specifying a standard storage device that is for testing all
applicable STBs across the board. DOE requests comment on the proposed
approach of not testing STBs with external storage as a DVR. If DOE
does consider testing the STB with an external storage device as a DVR
in response to comments, DOE specifically requests comments on the
proper external storage device to use.
The definition of display device in the draft CEA-2043 standard is,
``a display device (example: TV, Computer Monitor, or Portable TV)
receives its content directly from a STB through a video interface
(example: HDMI, Component Video, Composite Video, or S-Video), and not
through a home network interface (HNI).'' DOE's proposed definition of
a display device adds clarification that the content that is received
from the STB through a video interface is displayed for viewing. DOE
proposes to include this clarification to the definition of display
device, because the definition specified in the draft CEA-2043 standard
explains the functionality of a display device but does not explicitly
define the device itself.
The definition of HNI in the draft CEA-2043 standard is, ``the
interface with external devices over a local area network (example:
IEEE 802.11 (Wi-Fi), MoCA, HPNA, IEEE 802.3, or HomePlug AV).'' DOE
proposes to include clarifying information in the definition of HNI to
explain that the interface is capable of transmitting video content.
DOE believes that the definition in the draft CEA-2043 standard, which
specifies that HNI is the interface with external devices over a local
area network, is vague and could potentially include other interfaces
that may not be capable of transmitting video content, and therefore,
not applicable for connecting with a STB. Therefore, DOE is proposing
to clarify that the HNI connection should be such that is capable of
transmitting video content.
Finally, DOE proposes to include a definition for content provider
and multi-stream that is not included in the draft CEA-2043 standard.
DOE is proposing a definition for content provider because the term is
used in today's proposed test procedure to explain the type of content
that should be streamed to a connected display device or client. DOE's
proposed definition for multi-stream was adopted from an older version
of the draft CEA standard, which included this definition. While CEA
has removed the definition for multi-stream from the most recent
version of the draft, DOE proposes to include it in this NOPR because
DOE uses the definition to describe STBs that have multi-streaming
capability and also proposes a multi-stream test to determine the power
consumption of such STBs (section III.G.5.b).
In addition to the definitions adopted from the draft CEA-2043
standard, DOE proposes to include the terms ANSI, IEC, ISO, and SCTE in
the definition section of the proposed Appendix AA to Subpart B of 10
CFR Part 430. These terms are used in the definitions of POD and Smart
Card and therefore, DOE has included the full forms of these terms.
DOE invites interested parties to comment on the proposed
definitions for the STB test procedure NOPR, and, in particular, the
clarifying information included for the definitions of DVR, display
device, HNI, and the definitions included for content provider and
multi-stream.
5. Definitions of Power Modes
While power mode is defined in section III.D.4 above, DOE proposes
to define the different modes of operation for the STB in further
detail similar to those provided in section 6 of the draft CEA-2043
standard. The draft CEA-2043 standard describes the on, sleep, and off
modes of STB operation, which are defined and discussed below. The
proposed power mode definitions would be included in section 2.25
(Definition of Power Modes) of the proposed Appendix AA to Subpart B of
10 CFR Part 430. DOE invites interested parties to comment on the
proposed definitions for each mode of operation of the STB.
On mode: The STB is connected to a mains power source. At least one
principal STB function is activated and all principal STB functions are
provisioned for use. The power consumption in on mode may vary based on
specific use and configuration.
DOE's view is that a STB has ``all principal STB functions
provisioned for use'' if all principal STB functions are prepared or
equipped for use by the consumer. This description of on mode aligns
with the consumer's expectation of what a STB should do when it is
turned on, or when it is ``in-use''. The proposed definition also
aligns with the definition in the ENERGY STAR specification for on mode
operation.
Sleep mode: A range of reduced power states where the STB is
connected to a mains power source and is not providing any principal
STB function. The STB may transition to on or off mode due to user
action, internal signal, or external signal. The power consumed in this
mode may vary based on specific use or configuration. If any principal
STB function is activated while operating in this mode, the STB is
assumed to transition to on mode. Monitoring for user or network
requests is not considered a principal STB function. The STB shall be
able to transition from this mode to on mode within 30 seconds, to be
considered in sleep mode.
The proposed definition for sleep mode is similar to the definition
for sleep mode in the draft CEA-2043 standard with one key addition.
The proposal that the STB should transition to on mode within 30
seconds has been included to ensure that a valid sleep mode includes
the ability to resume full functionality in a timely manner. DOE
received a comment from AT&T in response to the 2011 RFI that
referenced consumer studies to indicate strong consumer resistance to
any recovery time from ``minimum power'' mode longer than 1 minute.
(AT&T, No. 0032 at p. 16) AT&T further indicated that this was true
even when the consumer was prompted that longer recovery times would
have environmental and energy saving benefits. (AT&T, No. 0032 at p.
16) Additionally, CA IOUs indicated that long wake times are a
significant barrier to consumer adoption. (CA IOUs, No. 0033 at p. 6)
NCTA also commented that a STB could take much longer than 2 to 5
minutes if the STB were to shut off power
[[Page 5085]]
completely, which would negatively impact the user's experience. (NCTA,
No. 0034 at p.14)
Because the overall energy consumption of a STB is dependent on
consumer adoption of sleep modes that can resume functionality quickly,
DOE proposes to set a maximum allowable transition time of 30 seconds
from sleep mode to on mode, which is half the acceptable duration
referenced in AT&T's studies. If the STB cannot transition from sleep
mode to on mode in 30 seconds or less, it is not considered to have
sleep mode capability and shall not be tested for the energy
consumption in sleep mode, which is discussed in section III.G.6. That
is, if the STB does not transition from sleep mode to on mode within 30
seconds, the value of the power consumption in sleep mode for the AEC
metric (discussed in detail in section III.I of the NOPR) would be set
equal to the power consumption in on (watch TV) mode for such STBs. It
is DOE's view that market forces will drive STBs to utilize a shorter
transition period; however, DOE adds this limit as an upper bound to
facilitate consumer adoption of sleep mode. If a STB takes very long to
resume functionality from sleep mode, it is DOE's assumption that
consumers are less likely to place the STB in sleep mode. The 30 second
upper limit may mitigate some of these consumer concerns of resuming
functionality quickly from sleep mode. DOE also considered other
allowable transition times less than 30 seconds or more than 30
seconds. However, its view is that a transition time shorter than 30
seconds may be too restrictive for certain STB designs. Conversely, DOE
believes a transition time greater than 30 seconds may discourage
consumers from using sleep mode and would affect DOE's estimated usage
profile for the calculation of AEC as discussed in section III.I.
DOE recognizes that imposing the 30 second requirement would not
measure any sleep power saving techniques that may take longer than 30
seconds to resume functionality and may subsequently discourage power
saving techniques in that area. On the other hand, excluding this
requirement would essentially treat all low power sleep modes the same
for the purposes of power measurement, regardless of whether or not the
STB resumed functionality quickly. STBs that resume functionality more
quickly could have higher consumer adoption and thus, more overall
energy savings, which would not be captured if there were no
requirement for resuming functionality. This is because, as indicated
by AT&T's consumer studies and other public commenters, consumers are
less likely to use the various sleep modes if it takes too long to
resume functionality,, which would result in more STBs staying in on
mode all day. Therefore, DOE is proposing the requirement that the STB
shall transition to on mode within 30 seconds and requests stakeholders
to comment on the proposed requirement.
DOE invites interested parties to comment, and provide data if
available, on the proposed requirement of transitioning from sleep mode
to on mode within 30 seconds or whether a different maximum allowable
transition time should be considered.
Off mode: The STB is connected to a mains power source, has been
de-activated, and is not providing any function. The STB requires a
user action to transition from this mode to on or sleep mode.
The proposed definition for off mode is exactly as specified in the
draft CEA-2043 standard. A STB that is de-activated does not provide
any functions and a user action is required for the STB to provide any
function. A user action means an action that would require the consumer
to interact with the STB using either a single or a series of
keystrokes or button presses, either on a remote control or on the STB
unit. DOE understands that this is the generally accepted definition by
industry for off mode.
E. Test Conditions
1. Set-Top Box Settings
DOE received comments regarding the configuration in which the STB
should be setup for testing. NCTA stated that STBs should be tested in
``as-shipped'' condition and as normally installed for an end-user.
(NCTA, No. 0034 at p. 19) AT&T and CEA commented that in order to
reduce the risk of stifling innovation, the STB test procedure
rulemaking should require that newly introduced features be turned off
to the extent possible. CEA commented similarly but further stated that
turning off newly introduced features during testing could reduce the
accuracy and utility of the test procedure. (AT&T, No. 0032 at p. 22)
(CEA, No. 0031 at p. 5)
DOE proposes the following requirements for setting up the STB for
testing. There are different requirements depending on whether the STB
can be installed by the consumer using the user manual shipped with the
unit or whether a technician is required to install the STB per the
manufacturer's instructions. These proposed requirements are included
in section 3.1 (Set-top Box Settings) of the proposed Appendix AA to
Subpart B of 10 CFR Part 430.
For all STBs that require subscription to a service, the simplest
available video subscription that supports all functionality proposed
in today's test procedure shall be selected for operating the STB. That
is, subscriptions with TV services only shall be selected and packages
with non-video capability, such as telephony, shall not be selected.
If the STB can be installed by the consumer per the manufacturer's
instructions without the service of a technician, then it shall be
installed and setup according to the user manual shipped with the unit.
Only those instructions in the user manual should be used for setting
up the STB and setup should be considered complete once they are
followed.
If the STB must be installed by a technician per the manufacturer's
instructions, then the unit shall be setup as installed by the
technician for testing. All steps that a technician would follow when
installing a STB for use in a consumer residence should be followed.
DOE recognizes that for testing a STB in the setup in which it is
installed in a consumer's home, a third-party test lab would require
this setup information. Therefore, information about each of the steps
that were performed to setup the STB by a technician shall be recorded
and maintained by the manufacturer pursuant to 10 CFR Part 429.71 as
part of the test data underlying the ratings.
The goal of DOE's proposed requirements for the STB settings is to
ensure that the STB is tested under the same settings as it would be
when installed in a consumer's home. This proposal is similar to an
older draft version of the CEA-2043 standard, which required STBs to be
tested in the configuration in which it is supplied to consumers. DOE
proposes to use the simplest available video subscription that supports
all functionality proposed in today's test procedure for testing
because, at a minimum, all STBs will provide these services. Testing
all STBs with the simplest subscription ensures consistency across
testing of the different STB models. Further, DOE believes that setting
up the STB in the same configuration that the consumer would use the
STB, ensures that the test is representative.
DOE requests comment on the proposed requirements for setting up
the STB as installed in a consumer's home for testing.
In regards to comments made by AT&T and CEA about newly introduced
features on STBs, DOE disagrees with commenters and is not proposing to
turn off or disable any such features.
[[Page 5086]]
DOE believes that turning off newly introduced features that are
enabled as part of the typical set-up process would not be
representative of the energy use the consumer would see once installed.
Instead, it is more representative of the consumer's use to keep these
features in the setting in which they are when first installed in a
consumer's home per the manufacturer's instructions. DOE expects that
most consumers typically do not change the settings of the STB after it
is installed. That is, DOE believes the configuration in which the STB
is installed by a technician is the configuration in which the STB is
operated most commonly and, therefore, keeping non-tested features in
these initial settings would capture the most representative energy
consumption of the STB. This proposed requirement is consistent with
requirement specified in section 8.1.9 of the draft CEA-2043 standard,
which optionally specifies that non-tested product features may be left
in the default condition.
2. Test Room
DOE proposes to specify ambient conditions for testing STBs that
are similar to the requirements specified in section 7.3 of the draft
CEA-2043 standard. DOE recognizes that the power consumption of the STB
could vary with the ambient conditions of the room in which the STB is
tested. Therefore, the ambient conditions shall be controlled to ensure
that the power measurements are repeatable and reproducible. The test
conditions specified in the draft CEA-2043 standard, proposed in this
NOPR, ensure that the test results are repeatable, reliable, and
consistent without significant test burden. These conditions are
discussed in further detail below and are included in section 3.2 (Test
Room) of the proposed Appendix AA to Subpart B of 10 CFR Part 430.
DOE proposes that testing shall be carried out in a test room where
the ambient temperature is maintained at 23 degrees Celsius ([deg]C)
5 [deg]C. DOE's believes that 23 [deg]C represents the
temperature of a typical room in which a STB may be used; it is DOE's
understanding that this is the temperature range in which most
household appliances are typically tested. Further, a tolerance of 5
[deg]C for the ambient temperature is achievable because temperature
measurement instruments generally provide for a greater accuracy than 5
[deg]C and DOE expects it would not be burdensome for test labs to
climate control the test room to meet these requirements. Finally, the
temperature requirement of 23 [deg]C 5 [deg]C is the same
as that specified in the ENERGY STAR specification, which requires that
the ambient temperature should remain between 18 [deg]C and 28 [deg]C,
inclusive, throughout testing.
DOE further proposes that the test room shall be such that the air
movement surrounding the STB shall be less than or equal to 0.5 meters
per second (m/s), as required in the draft CEA-2043 standard. However,
DOE understands that it may be difficult to maintain the required
ambient temperature range at such a low air speed. This is because the
heat generated from the STB may heat up the surrounding air, and at
such a low air speed, the ambient temperature may exceed the required
range. Since it is likely that the power consumption of a STB does not
change significantly at moderately higher air speeds, the requirement
specified in the draft CEA-2043 standard may be stringent in
conjunction with the temperature requirements. DOE therefore requests
comments and data, if available, on the proposed 0.5 m/s air movement
requirement and whether this value should be relaxed to a higher value
or removed altogether.
Finally, DOE proposes that the STB shall be tested on a thermally
non-conductive surface, which is a requirement specified in the draft
CEA-2043 standard. This requirement ensures that the internal
temperature of the STB is maintained at a level consistent with a
typical consumer setup, which usually does not have a thermally
conductive surface. DOE requests comment on the proposed test room
conditions for testing STBs, including the air temperature, air speed,
and thermally non-conductive test surface requirements.
F. Test Setup
1. Test Voltage
DOE proposes that the input power requirements for testing STBs
shall be as specified in section 7.4 of the draft CEA-2043 standard and
are included in section 4.1 (Test Voltage) of the proposed Appendix AA
to Subpart B of 10 CFR Part 430. These requirements state that an
alternating current (AC) power source shall be used to power the STB
with an input voltage of 115 volts (V) 1 percent. Further,
the frequency of the power source shall be 60 hertz (Hz) 1
percent. The total harmonic distortion of the supply voltage when
supplying power to the STB in the specified mode shall not exceed 2
percent, up to and including the 13th harmonic. Finally, the peak value
of the test voltage shall be between 1.34 and 1.49 times its rms value;
that is, the value of the crest factor shall be between 1.34 and 1.49.
DOE's understanding is that the proposed requirements for input power
are typical for testing consumer electronics and notes that this aligns
with the requirements specified in the ENERGY STAR specification for
qualifying STBs in the North American market. DOE invites interested
parties to comment on the proposed input power requirements.
2. Measurement Accuracy
DOE proposes to specify the accuracy of power measurements similar
to those required in section 7.2 of the draft CEA-2043 standard. These
requirements are included in section 4.2 (Measurement Accuracy) of the
proposed Appendix AA to Subpart B of 10 CFR Part 430. The draft CEA-
2043 standard specifies that power measurements of 0.5 watt (W) or
greater shall be made such that the uncertainty of the measurement is
less than or equal to 2 percent at the 95 percent confidence level. For
power measurements of less than 0.5 W, the uncertainty of the
measurement shall be less than or equal to 0.01 W at the 95 percent
confidence level. The resolution of the instrument used to measure
power shall be 0.01 W or better for power measurements of 10 W or less,
0.1 W or better for power measurements greater than 10 W and up to 100
W, and 1 W or better for power measurements greater than 100 W. For
equipment connected to more than one phase, the power measurement
instrument shall be equipped to measure the total power of all phases
that are connected. DOE's view is that these requirements are
reasonable and generally accepted by industry for the accuracy of power
measurements. The uncertainty requirements are specified in IEC-
62301,\27\ which is referenced by IEC-62087, and also match the
requirements listed in the ENERGY STAR specification for testing STBs.
DOE invites interested parties to comment on the proposed requirements
for measurement accuracy.

Measurement of standby power.'' Edition 2.0 2011-01.
---------------------------------------------------------------------------
3. Test Equipment
Section 7.5 of the draft CEA-2043 standard provides recommendations
for equipment that may be used to monitor AC line current, voltage, and
frequency. DOE proposes to include this recommended equipment that is
optional for testing. The following recommended equipment are included
in section 4.3 (Test Equipment) of the
[[Page 5087]]
proposed Appendix AA to Subpart B of 10 CFR Part 430:
(1) An oscilloscope with a current probe to monitor the AC line
current waveform, amplitude, and frequency.
(2) A true rms voltmeter to verify the voltage at the input of the
STB; and
(3) A frequency counter to verify the frequency at the input of the
STB.
DOE's view is that these instruments would be appropriate to ensure
that the current, voltage, and frequency measurements are accurate. DOE
invites interested parties to comment on the recommended test equipment
to measure the AC line current, voltage, and frequency.
4. True Power Wattmeter
DOE proposes that the power meter attributes shall be as specified
in section 7.5.2 of the draft CEA-2043 standard, which provides the
crest factor, bandwidth, frequency response, and sampling interval
requirements for the power wattmeter. Each of these attributes is
discussed in section III.F.4.a through III.F.4.d below and are included
in section 4.4 (True Power Wattmeter) of the proposed Appendix AA to
Subpart B of 10 CFR Part 430. These requirements are necessary because
electronic equipment can cause harmonics that lead to inaccurate power
measurements. The proposed requirements are standard specifications for
measuring power using a power wattmeter and are listed as the
characteristics of approved meters in IEC-62301. Additionally, these
requirements are specified in the ENERGY STAR specification for testing
STBs. Due to widespread industry acceptance, DOE's view is that these
requirements are reasonable and it should not be burdensome for
stakeholders to meet these conditions. DOE invites interested parties
to comment on the proposed power meter instrumentation requirements,
such as the crest factor, bandwidth, frequency response requirements,
and sampling interval.
a. Crest Factor
DOE proposes that the crest factor attributes shall be as specified
in the draft CEA-2043 standard, which requires that the power wattmeter
shall have an accuracy and resolution in accordance with that proposed
in section III.F.2 of this NOPR and sufficient bandwidth. Additionally,
the crest factor rating shall be appropriate for the waveforms that are
measured, and it shall be capable of reading the available current
waveform without clipping the waveform. Consistent with the draft CEA-
2043 standard, DOE also proposes that the peak of the current waveform
that is measured during the on and sleep modes of the STB shall be used
to determine the crest factor rating and the current range setting. The
full-scale value of the selected current range multiplied by the crest
factor for that range shall be at least 15 percent greater than the
peak current to prevent measurement error.
b. Bandwidth
DOE proposes the following requirements as specified in the draft
CEA-2043 standard. The current and voltage signal shall be analyzed to
determine the highest frequency component (that is, harmonic) with a
magnitude greater than 1 percent of the fundamental frequency under the
test conditions. Additionally the minimum bandwidth of the test
instruments shall be determined by the highest frequency component of
the signal.
c. Frequency Response
As specified in the draft CEA-2043 standard, DOE proposes that a
wattmeter with a frequency response of at least 3 kilo-hertz (kHz)
shall be used in order to account for harmonics up to the 50th
harmonic.
d. Sampling Interval
DOE proposes to adopt the sampling interval requirement as
specified in the draft CEA-2043 standard. This requirement specifies
that the wattmeter shall be capable of sampling at intervals less than
or equal to 1 second.
5. Calibration
DOE proposes to specify test instrument calibration requirements
that are identical to those required in section 7.5.1 the draft CEA-
2043 standard. The draft CEA-2043 standard specifies that the testing
equipment shall be calibrated annually to traceable national standards
to ensure that the limits of error in measurement are not greater than
0.5 percent of the measured value over the required
bandwidth of the output. The annual calibration requirement proposed by
DOE is typical for the equipment required for testing of all electrical
products. The proposed calibration requirements are included in section
4.5 (Calibration) of the proposed Appendix AA to Subpart B of 10 CFR
Part 430. DOE invites interested parties to comment on the proposed
calibration requirements for testing STBs.
6. Network Setup
a. Home Network Connection
As specified in section 8.1.4 of the draft CEA-2043 standard, DOE
proposes that for STBs that require the use of a home network, such as
thin-client STBs, an HNI connection shall be used. Further, DOE
proposes that the HNI connection shall be used in the following order
of preference: MoCA, HPNA, Wi-Fi, or any other HNI connection. That is,
if MoCA connection is available, the STB shall be tested using MoCA. If
MoCA is not available, HPNA shall be used followed by Wi-Fi as the last
option. These proposed requirements are consistent with the
requirements listed in the ENERGY STAR specification and are sequenced
based on most commonly used HNI connections to least commonly used HNI
connections. These requirements are included in section 4.6.1 (Home
Network Connection) of the proposed Appendix AA to Subpart B of 10 CFR
Part 430. DOE invites interested parties to comment on the proposed
requirements for testing STBs that require an HNI connection. DOE also
requests comment about whether there are any additional HNI connections
that should be included and the order of preference in which they
should be included.
b. Broadband Service
DOE proposes to specify setup requirements for STBs requiring
broadband service connections that are similar to the requirements
stated in section 8.1.5 of the draft CEA-2043 standard. These
requirements are included in section 4.6.2 (Broadband Service) of the
proposed Appendix AA to Subpart B of 10 CFR Part 430. The draft CEA-
2043 standard specifies that if the STB includes an HNI and the HNI
shall be connected to broadband service for operation of a principal
STB function, then it shall be tested while connected to a broadband
network. Broadband performance criteria, such as download speed, upload
speed, and latency shall meet the specific requirements of the STB to
fulfill the principal STB functions. DOE understands that certain STBs,
such as IPTV STBs, require a broadband connection to provide the
principal STB functions and is therefore proposing this requirement.
DOE also proposes to include clarification that for STBs designed to
operate both with a broadband connection and service provider network
connection (as discussed in section III.F.6.e), the service provider
connection takes precedence, and a broadband connection shall only be
made if the STB requires it for operating a principal STB function.
This clarification has been included because there may be some STBs
that are able to provide service on both a broadband network as
[[Page 5088]]
well as a service provider network. DOE's understanding is that STBs
typically operate on the service provider network connection rather
than the broadband connection, and thus, proposes to test with only the
service provider connection unless a broadband connection is required.
DOE requests comment on the proposed setup requirements for STBs
requiring broadband service as well as the clarification that a service
provider network connection takes precedence over a broadband
connection for STBs that are designed to operate on either connection.
c. Service Provider Network Distribution Equipment
As specified in section 8.1.6 of the draft CEA-2043 standard, DOE
proposes that for STBs that require the use of external equipment to
connect the service provider network to the STB, the power consumption
of the external equipment shall not be included with the power
consumption of the STB itself. If such equipment is integrated into the
STB in the future, the power consumption of the equipment shall be
included in the power consumption of the STB. Such external equipment
may include network gateways, network routers, network bridges, ONTs,
wireless access points, media extenders, or any other device that is
required for the distribution of a service provider network to the STB.
DOE is excluding the power consumption of the external equipment
because network distribution equipment does not meet the proposed
definition of the STB. As discussed in section III.B of this NOPR, if
DOE initiates a rulemaking for network equipment in the future, the
external equipment required to connect the service provider network to
the STB would likely be under the scope of that rulemaking. DOE invites
interested parties to comment on the proposed exclusion of external
equipment power consumption from the power consumption of the STB
itself. These requirements are included in section 4.6.3 (Service
Provider Network Distribution Equipment) of the proposed Appendix AA to
Subpart B of 10 CFR Part 430. If stakeholders indicate that the power
consumption of such external equipment should be included with the
power consumption of the STB, DOE requests input on the test method and
standard configuration that could be used to measure the power
consumed.
d. Input Signal Equipment
As discussed in section III.B of this NOPR, DOE received several
comments from stakeholders regarding the inclusion of specific types of
input signal equipment, such as LNB equipment, in the scope of this
proposed rule. However, as explained in section III.B, DOE does not
believe input signal equipment meets the definition of STB as proposed
in this NOPR because of significant operational differences from STBs.
There is no standard configuration for the number of STBs that can be
connected to any single input signal equipment. For example, for a
certain household an LNB may be connected to three STBs and a different
household may require two LNBs to connect three STBs. This lack of
standardization does not allow a direct comparison between the
different STBs that are connected to these equipment and therefore DOE
does not propose to test input signal equipment while testing STBs.
Instead, DOE proposes to adopt the specifications stated in section
8.1.7 of the draft CEA-2043 standard with some modification. DOE
proposes that when an ODU, over the air (OTA) antenna amplifier, cable
TV (CATV) distribution amplifier, or similar signal equipment is
required to operate the STB, the measurement shall not include the
power consumption of this equipment, if it can be powered from a source
other than the STB. If the signal equipment cannot be powered from a
different source, then the power for these equipment shall be included
in the STB power consumption measurement, and the signal equipment
should be configured in its lowest power consuming mode. However, if
the equipment is powered from a source other than the STB, it shall be
powered from another source, and the signal equipment shall not deliver
any power to the connected STB.
DOE's proposed specification is slightly different from that in the
draft CEA-2043 standard. DOE proposes to include the requirement that
if the input signal equipment cannot be powered from a source other
than the STB, then it shall be powered from the STB and the power
supplied to these equipment shall be included in the STB power
consumption measurement. Further, DOE proposes to include the
additional clarification that the signal equipment should not deliver
any power to the STB, if the equipment is powered from a different
source, to avoid the possibility of circumvention. This would occur if
the power consumption of the STB is rated lower than the actual
consumption of the STB because a separately powered device, the input
signal equipment, provides the additional power required to operate the
STB. DOE also considered requiring the use of a direct current (DC)
block in order to prevent power transfer to and from any such input
signal equipment; however, DOE has not proposed this requirement
because the DC block could potentially impact the functionality of such
input signal equipment. These requirements are included in section
4.6.4 (Input Signal Equipment) of the proposed Appendix AA to Subpart B
of 10 CFR Part 430.
DOE requests comment on the proposed exclusion of the power
consumption of the input signal equipment from the power consumption of
the STB and the additional clarification that such equipment should not
supply power to the STB. DOE also requests feedback on the potential
use of a DC block to prevent power transfer to and from any input
signal equipment. Further, if stakeholders indicate that such equipment
should be tested and the power consumption be measured as part of this
proposed rule, DOE requests comment on the test method and standard
configuration that could be used to test this equipment.
e. Service Provider Network Connection
DOE received some comments from NRDC and CA IOUs about testing STBs
on a live network or closed network. NRDC commented that STBs should be
tested as they are deployed in the field with ``live'' head-end
equipment. (NRDC, No. 0017 at p. 4) Further the CA IOUs commented that
while testing performed on a live network would result in real power
consumption, it also may be impractical. They further stated that if
testing was performed during a period of a large software update, the
power consumption of the STB may be elevated and atypical.
Additionally, it may take longer measurement periods to yield
repeatable results on the live network. (CA IOUs, No. 0033 at p. 7)
Finally, DISH, EchoStar, and DIRECTV commented that the energy
consumption of a satellite STB on a live network is generally not
affected by geography, location, time of day, or subscription package,
which are possible sources of variation when using a live network.
(DISH, EchoStar, DIRECTV, No. 0030 at p. 11)
Based on its review of the comments received, the practicality of
testing a STB on a live network compared to a closed network, and a
review of CEA's requirements in the draft CEA-2043 standard, DOE
proposes to adopt the same requirements listed in section 8.1.8 of the
draft CEA-2043 standard. These requirements allow either a live network
or closed network to be used for testing and provide specific
[[Page 5089]]
requirements for both. The draft CEA-2043 standard specifies that the
STB shall be tested with a specific service provider network or a
simulated environment that is verified by the service provider, and the
STB shall be configured to simulate a subscriber operating environment.
This shall include the ability to access the full services of the
service provider network required by the STB. These services include
content, program guides, software updates, and other STB features that
require network services to function completely. If the STB requires a
POD or Smart Card, then it shall be connected, authorized, and
operational. Essential peripheral devices that are required for the
normal operation of the STB, such as a Universal Serial Bus (USB)
powered external HDD, a USB powered Wi-Fi dongle, or a USB powered OTA
receiver, shall be connected and operational during testing. Optional
peripheral devices shall not be connected to the STB.
For testing the STB in a laboratory environment, DOE proposes to
adopt the specification in the draft CEA-2043 standard, which states
that the STB may be tested in a laboratory environment containing
control equipment comparable to a live service provider system. For a
cable STB, this would require a laboratory that contains a conditional
access system, the appropriate equipment to communicate with the STB
(such as ANSI/SCTE 55-1 \28\ or ANSI/SCTE 55-2 \29\ forward and reverse
data channel hardware or data-over-cable service interface
specification (DOCSIS) infrastructure), and the appropriate
interconnections (such as diplexers, splitters, and coaxial cables).
DOE proposes to incorporate by reference, in 10 CFR Part 430.3, the
industry standards ANSI/SCTE 55-1 and ANSI/SCTE 55-2 to describe the
equipment required to communicate with the STB when testing in a
laboratory environment.

---------------------------------------------------------------------------
These requirements are included in section 4.6.5 (Service Provider
Network Connection) of the proposed Appendix AA to Subpart B of 10 CFR
Part 430. DOE invites interested parties to comment on the proposed
requirements for service provider network connection. Particularly, DOE
requests comment and data, if available, about whether the power
consumption of a given STB is similar when it is operated on a live
network versus a closed network.
G. Test Method and Measurements
1. Set-Top Box Warm-Up
The first step in measuring the power consumption of the STB after
setting up the test room and equipment is to connect the STB and
operate it for a certain period of time until it reaches a stable
condition. It is important to warm-up, or stabilize, the STB so that
the measured values of power consumption are not fluctuating
dramatically, and a repeatable measurement can be taken. To stabilize
the STB, DOE proposes to adopt the requirement specified in section
8.1.1(e) of the draft CEA-2043 standard. The standard requires the STB
be operated in on mode (as discussed in section III.G.5 of this NOPR)
while receiving and decoding video for at least 15 minutes for the STB
to achieve stable condition. DOE expects that 15 minutes should be
sufficient to warm-up the STB. This warm-up is also consistent with the
ENERGY STAR test method. The STB warm-up requirements are specified in
section 5.1 (Set-top Box Warm-up) of the proposed Appendix AA to
Subpart B of 10 CFR Part 430. DOE invites interested parties to comment
on the proposed warm-up time for stabilizing the STB.
2. Test Configuration Information
To test the STB in on, sleep, and off modes, DOE proposes to
specify the configuration in which the STB shall be connected with one
or more display devices and clients. This information is not specified
in the draft CEA-2043 standard; instead section 8.1.11 of the standard
states that the entity specifying the use of the CEA standard is
expected to provide this information. Because DOE is proposing to adopt
the requirements specified in the draft CEA-2043 standard, DOE
qualifies as the entity specifying the use of the CEA standard.
Accordingly, DOE proposes to specify this information, as discussed in
the following paragraphs. The proposed test configuration information
is included in section 5.2 (Test Configuration Information) of the
proposed Appendix AA to Subpart B of 10 CFR Part 430.
The draft CEA-2043 standard requires the following information to
be specified: a configuration diagram of the STBs, clients, display
devices, and any other devices required for testing; the specific
network technology to be used for each test, if applicable; the maximum
number of connected display devices and clients for each test, if
applicable; devices in the network configuration that cannot be tested;
required tests to be run on each device; and, test parameters for each
required test.
Accordingly, DOE proposes to specify that the test configuration
described in Table 1 shall be used to configure all STBs and connected
devices. Because it is possible to configure STBs in several different
ways, DOE is proposing a table that lists the priority in which STBs
shall be configured rather than providing several different
configuration diagrams to cover the various possibilities. For multi-
streaming STBs, the proposed configuration in Table 1 describes the
number of display devices and clients that shall be connected to the
STB depending on its capabilities. If a STB is not capable of multi-
streaming, that is, if the STB cannot connect to multiple display
devices and does not support DVR and clients, then it shall be
connected to only one display device according to the proposed
configuration in the last row of Table 1. Each STB type is expected to
fall in one of the rows of Table 1 only. For example, a STB with DVR
capability that supports connections to multiple display devices and
clients shall be connected to one display device and one client
according to the configuration proposed in the first row of Table 1.
DOE developed the proposed configuration table such that a maximum of
three different content streams are enabled for multi-streaming STBs
for the multi-stream test, which is discussed in section III.G.5.b.
[[Page 5090]]

* The highest number of connections supported by the STB shall be used.
DOE further proposes that the same test configuration shall be used
throughout testing in the on, sleep, and off modes of operation for all
STBs. The draft CEA-2043 standard also requires DOE to propose the
maximum number of display devices and clients that shall be connected
to the STB. Because the number of connections depends on the
configuration that is feasible from Table 1, DOE is not proposing the
maximum number of connections. Instead, DOE proposes to use as many
connections as required for the configuration that is feasible from
Table 1. For example, a STB that can be connected to multiple display
devices and a client, but does not have DVR capability, shall be
connected to two display devices and one client throughout testing.
DOE proposes that the connection type that is used to connect the
display device to the STB shall be selected in the following order of
preference. The first preference shall be to connect a display device
to the STB using an HDMI connection, followed by Component Video, S-
Video, and Composite Video, respectively. If none of these connections
are available or feasible, then any other video interface that is
feasible shall be used. The order of preference for connecting display
devices to the STB is adopted from the comments received from
stakeholders in response to the TVs test procedure rulemaking. 77 FR
2830, 2839-2840 (January 19, 2012). Sharp commented that video input to
a TV should be selected in the following order: HDMI, Component Video,
S-Video, and Composite Video. (EERE-2010-BT-TP-0026, Sharp, No. 45 at
p. 6) Mitsubishi Electric Visual Solutions America (MEVSA) suggested
the following input hierarchy definition: ``Testing shall be performed
using a HDMI input. If the TV does not have an HDMI input, the
following inputs shall be used in the following order: component, S-
Video, and composite. If the TV has none of these inputs, an
appropriate interface shall be used.'' (EERE-2010-BT-TP-0026, MEVSA,
No. 44 at p. 3)
Additionally, DOE proposes that the connection type that is used to
connect the client to the STB shall be an HNI connection. The order of
preference in which an HNI connection shall be selected is discussed in
section III.F.6.a of this NOPR.
Finally, the draft CEA-2043 standard provides that the entity
specifying the use of the CEA-2043 standard (which is DOE in this case)
is expected to specify the required tests to be run on each device and
the test parameters for each required test. DOE proposes these test
specifications in the on, sleep, and off modes in sections III.G.5 to
III.G.7 of the NOPR.
DOE invites interested parties to comment on all aspects of the
proposed configuration for testing STBs in the on, sleep, and off modes
of operation. DOE is especially interested in receiving comments on the
proposed connections for the test configuration. DOE also invites
comments on the proposed order of preference for connecting a display
device to the STB.
3. Test Conduct
DOE proposes to specify the type of content that shall be streamed
to each device that is connected to the STB according to the
configuration discussed in section III.G.2 above. The information about
the streaming content is included in section 5.3 (Test Conduct) of the
proposed Appendix AA to Subpart B of 10 CFR Part 430. While the
connections required for the STB configuration during testing shall
remain the same throughout testing, the number and type of test streams
that shall be enabled for the various tests are proposed to be
different. This is similar to the usage expected in a typical household
that has all display devices and clients connected to the STB at all
times, but the number of streams enabled to each connected device is
different depending on the number of active viewers on different
display devices at a given point of time. When multiple streams are
enabled to output connect to a display device, record on a DVR that is
integrated into the STB, or stream content to a connected client, DOE
proposes that the content streamed to each shall be different. That is,
the content outputted to a display device for viewing a channel shall
be different from the content recorded on a DVR, which shall also be
different from the content streamed to a connected client. DOE is
proposing this requirement because DOE believes consumers generally
view and record different content simultaneously. Further, DOE proposes
the following specifications for the content stream that is used for
streaming to a display device, DVR, and client.
a. Output to a Display Device
For tests requiring output to be sent to a display device(s), DOE
proposes that a channel shall be selected and viewed on the connected
display device(s) as required by the test configuration. If the STB
does not support channels, an appropriate SD or HD test stream shall be
selected and viewed on the display device(s). If more than one display
device is connected to the STB based on the test configuration that is
feasible, then the content outputted on each display device shall be
different.
DOE's proposed requirements for providing video output to a display
device have been adopted from the draft CEA-2043 standard, which
specifies that a channel, if supported, or other appropriate content,
shall be sent to a connected display device. DOE additionally proposes
that if multiple display devices are connected to the STB, then the
content on each display device shall be different. This requirement has
been specified because DOE believes it mirrors typical user operation
wherein if two TVs are operating in a household at the same time, most
of the time the content being viewed would be different. DOE requests
comment on the proposed
[[Page 5091]]
requirements for providing video output to a display device.
b. Recording for a STB With DVR Capability
For tests that require recording on a STB with DVR capability, DOE
proposes that a channel shall be selected using a connected display
device or a client and the program shall be recorded. If more than one
recording is required on a DVR that is integrated into the STB, the
content for each recording shall be different.
DOE is proposing to test the record functionality of STBs with DVR
capability because it believes that this is one of the most commonly
used features of such a STB. The proposed method to record the content
on a DVR that is integrated into the STB is adopted from the draft CEA-
2043 standard's on (record)--DVR STB test. Similar to its proposal in
section III.G.3.a above for outputting content to a display device, DOE
is proposing that different content be recorded on a DVR integrated
into the STB if more than one recording is enabled. This is because it
is unlikely that users would record the same programming
simultaneously. DOE invites comment on the proposed requirements to
record on a DVR integrated into the STB.
c. Streaming to a Connected Client
DOE proposes that the content streamed to a client shall be
selected in the following order of preference depending on the number
of streams enabled. The first available stream that is supported by
each connected client shall be enabled and the content on each stream
shall be different. The first preference shall be to use a stream with
recorded content to stream to the client. That is, content that has
been recorded previously shall be streamed to the client and viewed on
a display device connected to the client. If the client does not
support streaming of recorded content, then a stream with channel
content shall be used. That is, a channel shall be viewed on the
display device connected to the client. An SD test stream shall be
viewed if it is an SD client and an HD test stream shall be viewed if
it is an HD client. For clients that do not support channels, an
appropriate SD or HD test stream shall be selected and viewed. Finally,
if the client does not support either a recorded stream or a channel
stream, then any other stream that is supported by the client shall be
used.
DOE believes that by proposing a hierarchy for the selection of
streams for the connected client(s), there will be consistency and
repeatability between tests without imposing an undue burden on
manufacturers. DOE selected the proposed hierarchy based on the most
power consumptive option to the least power consumption option. The
power consumed by a STB when streaming recorded content, which requires
the HDD to operate as well, is expected to be higher compared to when
streaming a channel. This proposed hierarchy would ensure consistency
in the results by accounting for the power differences.
DOE's proposed specification for playing back recorded content or
streaming a channel to the connected client is adopted from the
requirements specified in the draft CEA-2043 standard's on (play)--DVR
STB test and on (watch TV) test, respectively. DOE requests comment on
the proposed requirements to stream to a connected client.
Specifically, DOE requests comment on the proposed hierarchy of content
to stream to a connected client.
4. Calculation of Average Power Consumption
For all tests in the on, sleep, and off modes (NOPR sections
III.G.5, III.G.6, and III.G.7, respectively), DOE proposes that the
average power consumption shall be calculated using one of two methods.
The two proposed methods are included in section 5.4 (Calculation of
Average and Rated Power Consumption) of the proposed Appendix AA to
Subpart B of 10 CFR part 430.
The first method is as specified in section 8.2.1 and 8.3.1 of the
draft CEA-2043 standard. The standard specifies that the accumulated
energy (Ei) in kWh consumed over a period of time
(Ti) shall be recorded and the average power consumption
(Pi) is calculated as the quotient of the accumulated energy
over the time period, that is, Pi = Ei/
Ti. DOE proposes to adopt this specification from the draft
CEA-2043 standard to determine the average power consumption and, in
addition, proposes a second method to calculate average power.
The second method proposed by DOE allows for the average of
multiple power samples at a rate of at least 1 sample per second. The
average power value is calculated by taking the arithmetic mean of all
the power samples over a period of time. This type of measurement is
typical of many laboratory setups that perform AC power measurements
and therefore DOE is proposing to allow this method in addition to the
accumulated energy consumption method above.
For both methods, DOE is proposing an average power measurement
rather than an instantaneous measurement. This is consistent with
comments from CA IOUs, who are in favor of using an average power
consumption value rather than an instantaneous one. Specifically, the
CA IOUs commented that if testing is performed during a period of a
large software update, the power consumption of the STB could be
elevated and atypical. (CA IOUs, No. 0033 at p. 7) DOE believes an
average measurement would average out any elevated power consumption.
DOE is proposing an average measurement of power consumption based
on comments received from CA IOUs and DOE's internal testing results.
DOE tested eight STB models during internal testing using both HD and
SD test streams, for a total of 16 tests in the on, sleep, and off
modes of operation. The STBs that were tested included two STBs with
DVR functionality, two STBs without DVR functionality, and four over-
the-top (OTT) STBs. DOE also performed one repeatability test each on
three STBs using the HD test stream. The power meter that was used
during internal testing provided the accumulated energy consumption
over time (the first proposed method) as well as the average power
consumption values sampled over time (the second proposed method). The
average power consumption using both methods was the same. DOE sampled
the power consumption values over a duration of 10 minutes at the rate
of one sample per second. That is, DOE collected data that provided the
instantaneous power consumption at any point of time over the 10 minute
duration as well as the average power consumption over different time
periods (example: 2 minutes, 5 minutes, etc.). Figure 1 below compares
the instantaneous power versus the 2 minute and 5 minute average power
in the on mode for a STB that DOE tested internally. The power
consumption values have been normalized to the total average power over
the 10 minute test duration.
[[Page 5092]]
[GRAPHIC] [TIFF OMITTED] TP23JA13.000
Figure 1 indicates that an average value over 2 minutes and 5
minutes for the on mode test provided a more stable and repeatable
measurement compared to the instantaneous measurement. This result is
expected for STBs given the different activities that are performed
from time to time, such as maintenance or software updates. If the
power is measured at a particular instant, there is a possibility that
the recorded value may be too high or too low depending on the content
being streamed at that time. Further, for the sleep mode tests which
require the power consumption to be determined over 4 to 8 hours, an
average measurement could capture the potential decrease in power
consumption if the STB powered down into lower power modes, depending
on the time when the measurement is taken. DOE's proposed average power
measurement is consistent with the requirements specified in section
8.6.5 of the IEC 62087 standard as well.
DOE requests comment on the proposed methods to determine the
average power consumption of the STB in each mode of operation.
5. On Mode Power Measurement
For on mode testing, DOE proposes two tests: An on (watch TV) test
and a multi-stream test, which combines the multiple principal STB
functions into a single test. Rather than testing each individual
principal STB function separately, which may be burdensome to test, DOE
is proposing to use these two tests to best represent typical STB
usage. This would simplify testing as well as allow for different STBs
to be operated under different conditions. The on (watch TV) test
evaluates the power consumption of the STB when utilizing the most
basic function that all STBs share in common, watching a channel
outputted on a display device from a STB. The multi-stream test
evaluates the power consumption of the STB when multiple principal STB
functions are used simultaneously.
DOE further proposes that the time period for each test in the on
mode, TON, shall be 2 minutes. The draft CEA-2043 standard
from which DOE's proposed on mode test procedure is derived, does not
specify the duration of time the STB shall be operated for the on mode
test; instead, in section 8.1.11 it states that the entity specifying
the use of the CEA-2043 standard (which is DOE in this case) shall
specify the time period. Therefore, DOE is proposing that the duration
of the test shall be 2 minutes, which is consistent with the time
period specified in section 8.6.5 of IEC 62087 for the on mode tests.
Additionally, as shown in Figure 1 in section III.G.4 of the NOPR,
results from internal testing conducted by DOE indicated that the
average power consumption over 2 minutes was sufficient to provide
repeatable results. That is, the 2 minute moving average over a 10
minute test duration showed less variability compared to the
instantaneous power measurements. Additionally, the average power
consumption of the STB over 2 minutes was similar to the average power
consumption of the STB over 5 minutes during internal testing as seen
in Figure 1 in section III.G.4 of the NOPR.
DOE invites comment on all aspects of the proposed approach for
testing the STB in the on mode of operation.
a. On (Watch TV) Testing
DOE proposes to adopt the on (watch TV) test procedure specified in
section 8.2.2.1 of the draft CEA-2043 standard with some modification.
First, the STB shall be configured as proposed in Table 1 in section
III.G.2 of the NOPR. The STB shall be configured such that all devices
for the feasible configuration are connected to the STB. Of all the
connections to the STB, only one stream shall be enabled and shall
stream to a connected display device. All other connected display
devices and clients shall not have any content streamed to them. Next,
an SD channel shall be selected and viewed on the connected display
device. If the STB uses a content provider that does not support
channels, an appropriate SD test stream shall be selected and viewed on
the display device. Finally, the power consumption measurement shall be
started and the average power consumption shall be recorded for 2
minutes as PWATCH--SD. For STBs that support HD streaming,
the
[[Page 5093]]
test shall be repeated using HD content and the average power shall be
recorded for 2 minutes as PWATCH--HD. The average power
consumed in the on (watch TV) mode, PWATCH, shall be
calculated using the following equation:
[GRAPHIC] [TIFF OMITTED] TP23JA13.001
DOE's proposed method for testing in the on (watch TV) mode is
included in section 5.5.2 (On (Watch TV)) of the proposed Appendix AA
to Subpart B of 10 CFR part 430. DOE's proposed test method is
different from that specified in the draft CEA-2043 standard in one key
area. The draft CEA-2043 standard tests an HD STB using an HD test
stream only; DOE's proposed approach tests an HD STB for 2 minutes
using an SD test stream, followed by 2 minutes of testing using an HD
test stream. DOE proposes to use both the SD and HD test streams to
test HD STBs because it does not expect all content to be available on
an HD stream in the near future. That is, DOE's expectation is that HD
STBs may continue to stream some content using an SD stream because the
content would not be available in an HD broadcast stream. Therefore,
testing an HD STB using both an SD and HD test stream would represent
the typical use of an HD STB better than testing it on an HD stream
only. This requirement is also specified in the ENERGY STAR
specification, and it allows stakeholders the opportunity to represent
energy savings if a STB can be designed to consume less energy while
streaming SD content compared to streaming HD content. DOE expects this
additional test will have minimal impact on testing burden.
Further, DOE proposes that for HD enabled STBs, the average power
in on (watch TV) mode shall be the average of the average power
consumed using an SD stream and HD stream. DOE also considered whether
different weights, other than the average, should be used to combine
the power consumption using SD and HD streams for an HD STB that is
representative of consumers' usage of each of these streams. However,
DOE does not have any data that indicates the percentage of streams
that are available only in SD for HD STBs.
DOE requests comment on the proposed method to test the on (watch
TV) principal STB function. DOE also requests interested parties to
comment, and provide data if available, on the percentage of streams
that are available in SD and HD for HD STBs, and whether the proposed
equation for calculating PWATCH should be changed.
b. Multi-Stream Testing
To test other principal STB functions that are capable of multi-
streaming as defined in section III.D.4 of the NOPR, DOE proposes a
multi-stream test that simultaneously tests the most common STB
functions such as, viewing a channel, recording, and playback. The
proposed multi-stream test is included in section 5.5.3 (Multi-stream)
of the proposed Appendix AA to Subpart B of 10 CFR part 430. DOE
proposes to test the power consumption of STBs that are capable of
multi-streaming as follows: First, the STB shall be configured as
proposed in Table 1 in section III.G.2 of the NOPR. The STB shall be
configured such that all devices required for the feasible
configuration are connected to the STB. Next, the number of streams
that shall be enabled and the type of content that shall be streamed
using the STB shall be as specified in Table 2 of the NOPR. The highest
priority (smallest number in column 1 of Table 2) of streaming content
that is supported by the STB shall be selected. All streams required
for the supported priority shall be enabled using appropriate content
as described in section III.G.3 of the NOPR. As an example, if the STB
does not have DVR capability but can connect to multiple display
devices and clients, priority 3 shall be selected and the STB shall
output different content to two display devices and shall playback
previously recorded content on a connected client.
Table 2--Priority List for the Multi-Stream Test
----------------------------------------------------------------------------------------------------------------
Number of streams enabled
Priority for Enabling Multi-streaming - 1 is highest -----------------------------------------------------
priority - 9 is lowest priority To display To record on To connect to

7......................................................... 1 1 ................
8......................................................... 1 ................ 1
9......................................................... 2 ................ ................
----------------------------------------------------------------------------------------------------------------
If the STB or connected client supports HD streaming, an HD test
stream shall be used, otherwise an SD stream shall be used. Finally,
the multi-stream mode power consumption measurement shall be started
and the average power consumed by the STB shall be recorded for 2
minutes as PMULTI--STREAM.
The multi-stream test proposed by DOE to test multiple
functionalities of the STB simultaneously, is not explicitly specified
in the draft CEA-2043 standard, but the standard contains most of the
information that DOE has combined for the multi-stream test. The
standard specifies the methods to test the play (section 8.2.2.2 of the
standard) and record (section 8.2.2.3 of the standard) functionality of
STBs with DVR capability, it provides recommendations for concurrent
testing of networked STBs, and the different
[[Page 5094]]
tests that may be performed on different types of STBs. However, the
draft CEA-2043 standard does not require any of these tests and states
that the entity specifying the use of the draft CEA-2043 standard
(which is DOE in this case) shall provide the specific configuration
and type of tests to be performed. Therefore, DOE is proposing the
multi-stream test, which specifies that: (1) The STB shall be set up
according to the configuration in Table 1 in section III.G.2 of the
NOPR; and, (2) different functionalities that are to be tested shall be
enabled using the priority listed in Table 2. Once the STB is set up
and the different functionalities are enabled, the power consumption of
the STB in multi-stream shall be measured. To develop this proposed
multi-stream test for power consumption measurement, DOE has adopted
the draft CEA-2043 standard's play and record tests.
DOE's view is that the proposed multi-stream test is representative
of typical consumer usage of a STB compared to individually testing the
different STB features. That is, DOE expects that users would operate
multiple, different functions of the STB at the same time rather than
operate each function in sequence.
Further, for STBs that are capable of multi-streaming, DOE is
proposing that a maximum of three streams shall be enabled, if
feasible. If the STB supports only two streams, then two streams shall
be enabled. DOE is proposing to enable a maximum of three streams
because, according to data published by The Nielsen Company in January
2011, the average number of TVs per U.S. household is 2.5.\30\ Based on
this data, DOE approximated that a typical household in the U.S. has up
to three TVs and DOE assumed that a STB would typically be performing
up to three functions at a time. Therefore, DOE is proposing that a
maximum of three streams are enabled. While there may be STBs that are
capable of streaming more than three different content streams at a
time, attempting to test all available streams would result in testing
the STB at an extreme condition and would not be representative of
typical STB usage. DOE, however, is considering implementing a maximum
power test in which the STB is tested at maximum functionality where
the maximum number of streams is exercised simultaneously. DOE is not
currently proposing such a test, but requests feedback on including a
maximum streaming test, and if included, also requests comment on the
weightings that should be applied to the AEC calculation (discussed in
further detail in section III.I).

---------------------------------------------------------------------------
DOE invites interested parties to comment on the proposed test
procedure for testing STBs with multi-streaming capability. DOE is
especially interested in receiving comments on the proposed priority
list for enabling streams for testing STBs with multi-streaming
capability. DOE also seeks feedback on whether the number of additional
streams that should be enabled should be other than three and the
reasons for enabling a different number of streams. DOE requests
comment on the possibility of including a maximum power test, which
would test the STB such that the maximum number of streams are enabled.
If included, DOE requests comment on the weighting that should be
applied for the maximum streaming test in the calculation of the AEC.
6. Sleep Mode Power Measurement
For sleep mode testing, DOE proposes two tests only for those STBs
that are capable of transitioning from sleep mode to on mode within 30
seconds as defined in section III.D.5 of this NOPR. If the STB cannot
be placed in sleep mode, DOE proposes that this test be skipped. For
manufacturers that wish to determine whether a given basic model
contains a sleep mode that meets the 30 second transition time
requirement, DOE is proposing that the sleep to on mode transition time
test should be performed as described in section III.G.8 of the NOPR.
While this test is not necessary for determining the power consumption
values in the three modes, DOE would perform this test to determine how
the sleep mode consumption should be determined.
The two sleep mode tests are: A manual sleep test in which the STB
enters sleep mode through a user action, and an APD test in which the
STB automatically enters sleep mode after a period of user inaction.
The proposed sleep mode test is included in section 5.6 (Sleep Mode
Power Measurement) of the proposed Appendix AA to Subpart B of 10 CFR
Part 430.
DOE further proposes that the time period for each test in the
sleep mode, TSLEEP, shall be at least 4 hours and up to a
maximum of 8 hours. The time period shall be extended beyond 8 hours if
a network initiated action occurs which requires the sleep mode test to
be performed for a longer duration (discussed below in further detail).
Similar to the on mode test, section 8.1.11 of the draft CEA-2043
standard specifies that the entity specifying the use of the CEA-2043
standard (which is DOE in this case) shall provide the time period.
Therefore, DOE is proposing that the power consumption be determined
over 4 to 8 hours. The proposed time duration for the sleep mode tests
is much longer than the 2 minutes proposed for the on mode tests
because DOE expects that many STBs may transition to lower power
consumption modes after being in sleep mode for a couple of hours.
Testing over a duration of 4 to 8 hours shall capture the decreased
power consumption if it occurs within the 4 to 8 hour time period.
DOE considered other options for the time period over which the
average power of the STB in sleep mode should be measured, such as more
than 8 hours, only 8 hours, only 4 hours, or less than 4 hours. DOE did
not pursue the option of testing sleep mode over a period greater than
8 hours because of the large testing burden associated with such a long
duration. DOE also considered a value less than 4 hours but is
concerned that a STB may not power down to the lowest possible energy
consumption mode in less than 4 hours. DOE is proposing between 4 to 8
hours for testing the STB because it is the half (4 hours) to full (8
hours) duration of an expected over-night sleep mode of a STB, assuming
an 8 hour over-night duration during which most consumers are not using
the STB. Further, DOE expects that if a STB has the capability to power
down to lower sleep modes, it would do so within 4 to 8 hours.
For both, the manual sleep test and APD test, DOE proposes that
certain conditions be ensured while the STB is in sleep mode. That is,
it shall be ensured that no recording events are scheduled over the
entire duration of the test, including the time the STB is in on mode
prior to transitioning to sleep mode. Further, if a STB is capable of
scheduling a recording, a recording shall be scheduled 24 or more hours
into the future.
Next, no service provider network initiated action (such as,
content downloads or software updates) requiring a transition to on
mode shall occur over the 4 to 8 hours that the STB is in sleep mode.
If a service provider network initiated activity cannot be disabled,
then this requirement shall be monitored by sampling the power
consumption at a rate of at least 1 sample per second over the entire
duration of the test and observing the changes to the power consumption
over time. If the input power is less than or equal to 1 W, then a
linear regression through all power readings shall have a
[[Page 5095]]
slope of less than 10 mill-watts per hour (mW/h). If the slope of the
linear regression is equal to or greater than 10 mW/h, it is assumed
that a network activity has occurred and the test shall either be
restarted or extended until the slope is less than 10 mW/h. For input
powers greater than 1 W, a linear regression through all power readings
shall have a slope of less than 1 percent of the measured input power
per hour. If the slope is equal to or greater than 1 percent, it is
assumed a network activity has occurred and the test shall either be
restarted or extended until the slope is less than 1 percent. In
addition, if the test is extended beyond 8 hours to meet the required
conditions, the average power consumption over the entire test duration
shall be used to calculated the rated power consumption in sleep mode.
Finally, no local area network initiated actions requiring a
transition to on mode shall be scheduled over the 4 to 8 hours that the
STB is in sleep mode (example: mobile applications or other network
devices requesting service).
The above requirements for sleep mode testing have been adopted
from the draft CEA-2043 specification with some differences. For
example, section 8.3.1 of the draft CEA-2043 standard specifies that no
recording shall be scheduled while the STB is in sleep mode. However,
DOE proposes that no recording shall be scheduled for the entire
duration that the STB is tested for the sleep mode test, including the
time the STB is in on mode prior to transitioning to sleep mode. For
the manual sleep test, the time period in on mode is 5 minutes (as
discussed in section III.G.6.a of the NOPR) and for the APD test, this
time period is a maximum of 4 hours (as discussed in section III.G.6.b
of the NOPR). This proposed requirement enables the STB to transition
to sleep mode as desired, without any scheduled recordings keeping the
STB in on mode.
DOE is also proposing, for sleep mode testing, that a recording be
scheduled 24 or more hours into the future on STBs that are capable of
scheduling a recording. This proposed requirement is not part of the
draft CEA-2043 standard. DOE has included the recording requirement
because it understands that the power consumption of the STB may be
different when a recording is scheduled compared to when it is not.
When a recording is scheduled, the STB performs some non-primary
functions in the background to keep track of time and ensure that it
transitions to on mode once it is time to initiate recording. On the
other hand, if the STB does not have any recording or other functions
scheduled for the future, it may not perform any function until the
user transitions it back to the on mode using a remote control. DOE
expects that a STB in a consumer's home typically keeps track of some
command that requires it to initiate an action in the future while it
is still in sleep mode. For example, while the STB is in sleep mode it
may have to transition to on mode because the user had scheduled a
recording prior to placing it in sleep mode. Therefore, DOE proposes
that a recording shall be initiated 24 or more hours into the future
from test time.
Another difference between DOE's proposed test method and the
requirements specified in the draft CEA-2043 standard is that section
8.3.1 of the standard specifies that it shall be ensured that no
service provider network initiated actions occur while the STB is in
sleep mode. However, for STBs that may not be tested by a manufacturer
and are tested at a third-party laboratory, it might not be possible to
know when a service provider network initiated action occurs. Because
it is not possible to control the initiation of this activity, DOE is
proposing that the power readings recorded at a rate of at least 1
sample per second shall be observed for changes in power consumption
and a linear regression shall be performed to determine whether a
service provider initiated activity has occurred. As discussed above,
if the slope of the linear regression is greater than 1 percent, for
input powers greater than 1 W, then it is assumed a network initiated
action occurs and the test shall be restarted or extended until the
slope is less than 1 percent. The proposed requirements for analyzing
the power consumption readings have been adopted from the IEC 62301
standard with some modification. IEC 62301 specifies similar
requirements for determining the power consumption within a mode that
is not cyclic. A potential drawback of DOE's proposed method to check
for a network initiated action is that if the slope of the linear
regression is analyzed and used to gauge for network initiated
activities, it is possible that the slope may vary even when the STB
transitions to lower power consumption modes through the sleep mode.
That is, if a STB enters sleep mode when the ``Power'' button on the
remote is pressed, and then continues to transition to lower power
consumption modes over the 4 to 8 hour time period of the sleep mode
test, then the slope of the linear regression may not be less than 1
percent of the measured input power per hour as specified in the
requirements. In such a scenario, the test duration for the sleep mode
may be extended until the power consumption of the STB stabilizes
around a particular value. While this would increase the test burden
for manufacturers and third-party laboratory testing, an advantage
would be that the lowest power consumption modes of the STB would be
captured and included in the sleep mode power consumption measurements.
Alternatively, DOE is concerned that if the time period of the sleep
mode test is extended to be much longer than 8 hours, the test may
increase test burden.
DOE also considered other options to monitor for network initiated
activities, which it has not proposed in today's rulemaking. One of
these options would be to sample the power consumption at a rate of at
least 1 sample per second and determine if the power samples
continuously exceed the median power consumption by more than 10
percent of the median power for more than 15 minutes over the 4 to 8
hour sleep mode duration. However, DOE did not propose this approach
for several reasons. First, any value that is selected for comparing
the power samples to the median power (such as 10 percent in the setup
discussed here) as well as the duration of time (15 minutes) may not
encompass all possible scenarios of a transition from sleep to on mode
during the sleep mode test. For example, if a network event increases
power by 5 percent over a duration of 2 hours, this approach would not
capture the transition from sleep to on mode even though the increase
in power consumption would be significant. Another disadvantage of this
approach is that periodic events that may be intended to occur during
sleep mode would be falsely captured as a network initiated activity.
For example, if a STB wakes up for 15 minutes every 2 hours while in
sleep mode, this approach would capture it as a network event, while in
fact it is a scheduled activity that should be part of the sleep mode
power consumption measurement.
Another approach that DOE considered but has not proposed would be
to test the STB in sleep mode for a very long period of time, such as
24 hours, so that the effect of a network initiated activity is
mitigated over the long time period. However, DOE determined not to
propose this approach because of the significant test burden to testing
laboratories.
Finally, once all the conditions for performing the sleep mode test
are met, DOE proposes that the STB shall be configured as proposed in
Table 1 in section III.G.2 of the NOPR. The STB
[[Page 5096]]
shall be configured such that all devices required for the feasible
configuration are connected to the STB. Once the STB is configured it
shall be placed into sleep mode as described in section III.G.6.a for
the manual sleep test and as described in section III.G.6.b for the APD
test.
DOE invites comment on all aspects of the proposed specification
for setting up STBs for testing in the sleep mode of operation. In
particular, DOE is interested in receiving comments on the proposed
time duration of 4 to 8 hours over which the power consumption shall be
measured and whether this duration should be increased or decreased to
better represent STB power consumption in sleep mode. DOE also requests
comment on the proposed scheduled recording requirement prior to
placing the STB in sleep mode to measure its power consumption. DOE
requests interested parties to provide data, if available, on the
variation in power consumption of a STB when a recording is scheduled
versus when it is not. Finally, DOE invites interested parties to
comment on all aspects of the proposed method to address network
initiated actions. DOE requests comment and data, if available, on the
approach proposed in today's NOPR, the approaches that were considered
but have not been proposed, as well as any other approach that
stakeholders believe would best capture the transition of the STB from
sleep mode to on mode due to network initiated activities.
a. Manual Sleep Testing
DOE proposes to measure the STB power consumption in the manual
sleep mode only for STBs that can transition from sleep mode to on mode
within 30 seconds as defined in section III.D.5 of the NOPR. For STBs
that cannot support sleep mode, DOE proposes that the power consumption
in manual sleep mode, PSLEEP--MANUAL, shall be set equal to
PWATCH. For STBs that support sleep mode, DOE proposes to
measure the STB power consumption in manual sleep mode as follows. Once
the STB is configured it shall be operated in the multi-stream test
configuration (section III.G.5.b of the NOPR) for at least 5 minutes,
if the STB supports multi-streaming. If the STB does not support multi-
streaming, it shall be operated in the on (watch TV) configuration
(section III.G.5.a of the NOPR) for at least 5 minutes. Next, the
``Power'' button on the remote for the STB and each locally connected
display device and client shall be pressed momentarily (for less than 1
second) to place the STB and each locally connected display device and
client into sleep mode, as defined in section III.D.5 of the NOPR. The
STB remote control shall not be used (or moved) after the STB has been
placed in sleep mode. It must be ensured that the STB and each locally
connected client has entered sleep mode. This shall be done by ensuring
no channel viewing or recording is supported on the STB and clients.
That is, there shall be no video output on the connected display
device(s) from the STB and any locally connected clients. The manual
sleep mode power consumption measurement shall be started and the
average power consumed by the STB shall be recorded as
PSLEEP--MANUAL over the time period as determined in section
III.G.6 of the NOPR. DOE's proposed test for the manual sleep mode is
included in section 5.6.7 (Manual Sleep Test) of the proposed Appendix
AA to Subpart B of 10 CFR Part 430.
DOE is proposing to set PSLEEP--MANUAL equal to
PWATCH for STBs that may not necessarily support the manual
sleep mode test. This is because assigning a value of 0 kWh for the
power consumption in manual sleep mode for such STBs would be
misleading. A 0 kWh power consumption value in manual sleep mode may
indicate that the STB does not consume any energy when it is placed in
sleep mode, which is inaccurate. Further, for the purposes of the
calculation of the AEC metric (discussed in detail in section III.I of
the NOPR), setting PSLEEP--MANUAL equal to PWATCH
would count the STB as being in the on mode if it does not support the
manual sleep mode test. This would ensure that the AEC metric is a
representation of STB operation that is consistent with the definition
of sleep mode proposed in this NOPR.
DOE's proposed test procedure for determining the average power
consumed by the STB in manual sleep mode is similar to the requirements
specified in section 8.3.4 of the draft CEA-2043 standard for the sleep
mode test procedure, with some minor differences. While DOE proposes
that the STB shall operate in on mode for at least 5 minutes prior to
placing the STB in sleep mode, the draft CEA-2043 standard does not
specify any time requirement. DOE is proposing this requirement to
ensure that all STBs that are tested are operated for the same duration
of time prior to transitioning to sleep mode. DOE selected 5 minutes as
the minimum proposed duration to operate the STB in on mode prior to
placing it in sleep mode to ensure that the STB is fully functional
before sleep mode is initiated, without increasing the test burden
significantly. During internal testing (described in section III.G.4 of
the NOPR), DOE observed that none of the tested STBs took longer than 5
minutes to turn on and enable functionality. DOE believes this
requirement will ensure that there is consistency and repeatability
between tests without imposing an undue burden on manufacturers.
Another difference between DOE's proposed test and the draft CEA-
2043 standard is that the standard provides three different methods to
verify that the STB has entered sleep mode and specifies that any of
the three methods can be used for verification. These are: ensuring
that no channel viewing or recording is supported on the STB; observing
a sleep mode indicator on the STB, which may be found from the user
manual; or, waiting for a predetermined period of time that is provided
by the entity specifying the use of the CEA-2043 standard. Of these
methods, DOE is proposing to use the first approach, which requires
ensuring that no channel viewing or recording is supported on the STB.
DOE expects this method to be the most common way for determining
whether or not a STB has entered sleep mode. Not all STBs have a sleep
mode indicator on the box and a standard predetermined wait time for
all STBs could potentially be long or short for at least some of the
STBs. An individual check on each STB guarantees that the STB has
transitioned to sleep and that the measurement may be taken.
DOE invites interested parties to comment on the proposed
requirements for testing STBs in manual sleep mode.
b. Auto Power Down Testing
DOE proposes to perform an APD test as a second sleep mode test.
The APD test is included in section 5.6.8 (Auto Power Down (APD) Test)
of the proposed Appendix AA to Subpart B of 10 CFR Part 430. To measure
the power consumption of a STB that is capable of APD, DOE proposes the
following test. Similar to the manual sleep test, once the STB is
configured it shall be operated in the multi-stream test configuration
(section III.G.5.b of the NOPR) for at least 5 minutes, if the STB
supports multi-streaming. If the STB does not support multi-streaming,
it shall be operated in the on (watch TV) configuration (section
III.G.5.a of the NPR) for at least 5 minutes. Next, the ``Power''
button on the remote shall be pressed momentarily (for less than 1
second) only for any locally connected clients to place the connected
clients into sleep mode, as defined in section III.D.5 of the NOPR.
Additionally, if more than one display device is locally connected to
the STB, the ``Power'' button on the remote for the additional
[[Page 5097]]
locally connected display devices shall be pressed and the STB shall
stream content to one connected display device only. Once all but one
connected display device are ``off'', the STB remote control shall not
be used. The STB shall be operated until it enters sleep mode or until
4 hours elapse, whichever occurs first. If the STB does not transition
into sleep mode at the end of 4 hours, then the STB is not considered
to support APD and PSLEEP--APD shall be set equal to
PWATCH. Once the STB is in APD, the power consumption
measurement in APD shall be started and the average power shall be
recorded as PSLEEP--APD over the time period as determined
in section III.G.6 of the NOPR.
DOE's proposed test is similar to the manual sleep test discussed
in section III.G.6.a of the NOPR; the only difference is that in the
manual sleep mode test the STB is placed into sleep mode manually,
while in the APD test the STB transitions to sleep mode because no user
activity occurs over a certain time period. DOE's proposed test for APD
also has some differences from the power mode transition--``on to APD''
transition test described in section 8.5.1 of the draft CEA-2043
standard. First, the test specified in the draft CEA-2043 standard
records both the power consumption to transition from on mode to APD
and the time it takes to transition from on mode to APD. In DOE's
proposed test procedure, however, DOE proposes a maximum time of 4
hours for the STB to transition to sleep mode through APD. DOE proposes
that the STB should transition to sleep mode within 4 hours, or else
the STB is not considered to support APD. DOE's proposed 4 hour time
limit to transition to APD is adopted from the ENERGY STAR
specification, which states that products that offer the APD feature
should be shipped with APD enabled by default and with the APD timing
set to engage after a period of inactivity less than or equal to 4
hours.
DOE considers the 4 hour time limit to be reasonable because it
assumes that TV programming typically does not exceed 4 hours in
duration. Therefore, if a viewer is watching such programming without
sending any other commands to the STB over the duration of the program,
the STB may transition to APD at the end of 4 hours without shutting
off the viewer's program of interest. DOE also considered allowing the
STB configuration to be changed from its default APD behavior to a
shorter period for the purposes of testing APD as long as the default
behavior was to power down within 4 hours. This would shorten the test
time for the APD test; however, DOE does not propose this approach at
this time as it may not be clear as to whether or not the default
behavior meets the required 4 hour limit without exercising the test.
DOE also considered a period less than 4 hours for the APD test, but
preliminarily determined that any mandated time period that is shorter
may have a negative impact on the consumer, because it may transition
the STB to sleep mode while the consumer may still be viewing the
programming.
DOE also considered scaling the APD, wherein the power consumption
in APD would be dependent on the duration required for the STB to
transition from on mode to sleep mode using the APD feature. For
example, DOE currently proposes to assign 7 hours to the APD power
consumption value while calculating the AEC metric as discussed in
detail in section III.I of the NOPR. The proposed method to calculate
AEC allocates these 7 hours to APD assuming it would require 4 hours to
transition from on mode to sleep mode using the APD feature. DOE also
considered allowing for a higher daily hour allocation for STBs that
entered APD within 1 or 2 hours. However, DOE is concerned that
proposing scaling of power consumption in APD in the test procedure may
encourage manufacturers to use a very short default APD time period
that might be intrusive to the consumer experience. This would hamper
consumer adoption of APD because the STB may transition to sleep mode
while a consumer is still viewing content. In such a situation, if the
consumer disables the APD feature, the potential energy savings for APD
enabled STBs may not be realized in the field. While DOE is not
proposing a scaled APD power consumption value in today's NOPR, it
requests stakeholders to comment on potential methods to scale APD and
the advantages and disadvantages of scaling the power consumption in
APD. DOE also requests comment on the impact of a scaling APD power
consumption value on the proposed AEC metric (discussed in section
III.I of the NOPR) and potential methods to account for a scaling APD
value in the AEC metric.
Another difference between DOE's proposed test for APD and the test
specified in the draft CEA-2043 standard is that DOE proposes the same
configuration of connections for the STB as is used for all other
tests. In contrast, the test specified in the draft CEA-2043 standard
tests on an individual STB only. As discussed in section III.G.3 of the
NOPR, DOE's proposed method matches the usage expected in a typical
household. That is, all connected devices will be connected to the STB
at all times, but the STB will be performing different functions at
different times. Therefore, DOE has not changed the configuration in
which the STB is tested for the APD test.
DOE invites interested parties to comment on the proposed test for
determining the STB power consumption in APD. Particularly, DOE
requests comment and data, if available, on the time required to
transition to sleep mode and whether this time period should be set at
a default value of 4 hours or adjusted during testing.
7. Off Mode Power Measurement
DOE's proposed test procedure for determining the power consumption
of a STB in off mode is similar to the test procedure specified in
section 8.4.1 of the draft CEA-2043 standard. The proposed off mode
test is included in section 5.7 (Off Mode Power Measurement) of the
proposed Appendix AA to Subpart B of 10 CFR Part 430. DOE proposes the
following test to determine the off mode power consumption of the STB.
If the STB supports off mode as defined in section III.D.5 of the NOPR,
it shall be placed in off mode. If it does not support off mode as
defined in section III.D.5, this test shall be skipped. Next, wait
until the STB enters off mode and record the average power consumed by
the STB for 2 minutes as POFF.
DOE invites interested parties to comment on the proposed
requirements for testing STBs in off mode.
8. Sleep to On Mode Transition Time Measurement
DOE proposes to include a test to verify the time required to
transition from sleep mode to on mode to help manufacturers to
determine if the basic model contains a sleep mode per DOE's proposed
regulatory definition (discussed in section III.D.5 of the NOPR).
According to the definition proposed for sleep mode in section III.D.5
of the NOPR, a STB is considered to be in sleep mode only if it can
transition from sleep mode to on mode within 30 seconds. While STB
manufacturers may know the time it takes for the STB to transition, DOE
is including this test in today's proposed test procedure in the event
there is any uncertainty if the STB meets the sleep mode requirements.
The proposed test procedure for determining the transition time from
sleep mode to on mode is described below and has been adopted from
section 8.5.5 of the draft CEA-2043 standard's Power Mode Transition--
``Sleep to On'' Transition test method. The proposed sleep to on mode
transition time measurement test is
[[Page 5098]]
included in section 5.8 (Sleep to On Mode Transition Time Measurement)
of the proposed Appendix AA to Subpart B of 10 CFR Part 430.
DOE proposes the following test to determine the sleep to on mode
transition time. The test shall be used to verify two different cases.
First, to determine the transition time from sleep to on mode for the
manual sleep test, and second, to determine the transition time from
sleep to on mode for the APD test. For the manual sleep test, the STB
shall be placed into sleep mode according to the steps specified in the
manual sleep mode test (described in section III.G.6.a of the NOPR).
For the APD test, the STB shall be allowed to transition to sleep mode
from on mode automatically, according to the steps specified in the APD
test (described in section III.G.6.b of the NOPR). For both sleep mode
tests, once the STB enters sleep mode, wait until the STB power
consumption (PSLEEP, which is generic for
PSLEEP--MANUAL or PSLEEP--APD) is between
PSLEEP and PSLEEP + 0.5W. That is, the power
consumption should be less than PSLEEP + 0.5 W and greater
than PSLEEP. After the power consumption reaches the desired
value, wait for at least 5 minutes before pressing the ``Power'' button
on the remote or front panel of the STB. Once the STB is powered,
elapsed time measurement shall be started and the duration shall be
measured until the STB enters on mode. It shall be ensured that the STB
has entered on mode when it supports channel viewing on the connected
display device or client. The duration to transition from sleep mode to
on mode shall be recorded as TSLEEP--TO--ON. If
TSLEEP--TO--ON is greater than 30 seconds then
PSLEEP--MANUAL and/or PSLEEP--APD shall be set
equal to PWATCH.
DOE's proposed test to determine the transition time from sleep
mode to on mode is similar to the sleep to on mode transition test
specified in the draft CEA-2043 standard, with some additional
specifications. First, DOE's proposed test specifies that the STB shall
be placed into sleep mode in two different ways; manually using the STB
remote for the manual sleep test, and automatically for the APD test as
described in section III.G.6.b of the NOPR. DOE has included this
requirement to ensure that the STB is placed into sleep mode according
to both sleep mode tests proposed in this NOPR. Next, the draft CEA-
2043 standard does not explicitly specify the amount of time a STB
should be kept in sleep mode, but states that it should be for the
predetermined stabilization time. Therefore, DOE is proposing that the
STB shall remain in sleep mode for at least 5 minutes to stabilize the
STB in sleep mode. DOE believes that 5 minutes is a sufficient period
of time to ensure the STB has completed any remaining operations.
For the sleep to on mode transition time measurement test, DOE also
proposes that if TSLEEP--TO--ON is greater than 30 seconds,
then PSLEEP--MANUAL shall be set equal to PWATCH
and PSLEEP--APD shall also be set equal to
PWATCH. DOE has included this requirement because if the
transition time is greater than 30 seconds, then the STB will not meet
the sleep mode definition described in section III.D.5 of the NOPR and
will therefore, not be considered in sleep mode.
DOE requests comment on the proposed sleep to on mode transition
time measurement test.
H. Sampling Plan
DOE is proposing the following sampling plan and rounding
requirements for STBs to enable manufacturers to make representations
of power consumption in the on, sleep, and off modes of operation. The
represented power consumption values shall be used to calculate the AEC
metric (discussed in section III.I of the NOPR), which shall be rounded
according to the requirements proposed below. The sampling requirements
are included in the proposed section 429.55 of Subpart B of 10 CFR Part
429.
DOE is proposing to keep the minimum sample size of STBs that shall
be tested to determine rated power consumption at two, as defined in 10
CFR Part 429.11. However, manufacturers may choose to test a greater
number of samples of a given basic model, if desired. Additionally, DOE
is proposing that the rated value of power consumption in the on,
sleep, and off modes of operation of a basic STB model for which
consumers would favor lower power consumption values shall be greater
than or equal to the higher of the mean of the sample or the 95 percent
UCL of the true mean divided by 1.05. The equations below show the
calculation of the mean and the UCL, respectively.
The mean of the sample is calculated as follows:
[GRAPHIC] [TIFF OMITTED] TP23JA13.002
Where:
x = the sample mean,
n = the number of samples, and
xi= the ith sample.
The UCL is calculated as follows:
[GRAPHIC] [TIFF OMITTED] TP23JA13.003
Where:
x= the sample mean,
s = the sample standard deviation,
n = the number of samples, and
t0.95 = the t statistic for a 95 percent one-tailed
confidence interval with n-1 degrees of freedom.
Based on internal testing DOE conducted on STBs (described in
section III.G.4 of the NOPR), DOE expects that the proposed test
procedure can provide repeatability within 2 percent. Thus, DOE
proposes to divide the UCL value by 1.05. In the case where the two
samples differ by 2 percent, the UCL value will be 6 percent greater
than the mean, and dividing by 1.05 would result in a value that is
only 1 percent greater than the mean. Larger variances in samples would
result in greater UCL values as dictated by the 95 percent confidence
interval. DOE invites interested parties to comment on the proposed
sampling plan.
DOE proposes that only the mean and the UCL of the samples tested
shall be rounded, while all calculations to
[[Page 5099]]
determine the mean and UCL shall be performed with unrounded values.
For making representations using the power consumption values in each
mode of operation, DOE proposes that the accuracy requirements
discussed in section III.F.2 of the NOPR shall be used as rounding
requirements. The proposed rounding requirements for the rated power
consumption values are included in section 5.4 (Calculation of Average
and Rated Power Consumption) of the proposed Appendix AA to Subpart B
of 10 CFR Part 430.
Once the rated power consumption values for the on, sleep, and off
modes are calculated and rounded, DOE proposes that these rated values
shall be used to calculate the AEC metric, which is discussed in
section III.I of the NOPR. For the rounding requirements of the AEC
metric from the rated power consumption values, DOE proposes the
following: If the AEC is 100 kWh or less, the value shall be rounded to
the nearest tenth of a kWh. If the AEC is greater than 100 kWh, the
value shall be rounded to the nearest kWh. The proposed rounding
requirements for the AEC metric are also based on the accuracy
requirements discussed in section III.F.2 of the NOPR. The proposed
rounding requirements for the AEC metric are included in section 6
(Calculation of the Annual Energy Consumption of the Set-top Box) of
the proposed Appendix AA to Subpart B of 10 CFR Part 430.
DOE requests comment on the proposed rounding requirements for
representing the power consumption in each mode of operation and the
rounding requirements for the AEC metric, which is calculated from the
rated power consumption values.
I. Method To Calculate the Energy Consumption of a Set-Top Box
DOE received several comments about the metric that should be used
to determine the annual energy consumption of a STB. CA IOUs commented
that while typical energy consumption (TEC) calculation is common
practice for rulemakings, it would not work for STBs because these
products do not fit the mold for typically regulated products. (CA
IOUs, No. 0033 at p. 3) Instead, they suggested a metric that would
focus on sleep power levels. In contrast, AT&T commented that
consistency with the ENERGY STAR testing methodology was desirable,
particularly because regulation is being layered onto an already-
existing voluntary program. (AT&T, No. 0032 at p. 28) AT&T further
commented that the user profile should reasonably reflect the current
usage patterns of their customers. (Id.) Finally, Cisco commented that
the user profiles cannot be the only metrics considered by DOE for
establishing STB testing and standards. Cisco commented that STBs are
not manufactured based on the average usage profile, but on outlier
consumer usage and worst case scenarios addressing decoding, multiple
streams, maximal DVR usage, etc. (Cisco Systems, Inc., No. 0027 at p.
31)
Based on the comments received and analyzing the current STB
market, DOE proposes that individual power consumption values in each
mode of operation and an annualized energy metric, the AEC metric,
shall be the metrics from today's proposed test procedure. That is, the
power consumption in on mode (PWATCH and
PMULTI--STREAM), sleep mode (PSLEEP--MANUAL and
PSLEEP--APD), and off mode (POFF), and the AEC
metric are the results of the proposed test procedure.
The average power consumption in each mode of operation is
determined as described in sections III.G.5 through III.G.7 of the
NOPR. Once the individual average power consumption values are
determined, the rated power consumption in each mode of operation is
calculated using the sampling plan and statistics discussed in section
III.H. The rated power consumption in each mode of operation is then
rounded according to the rounding requirements which are also discussed
in section III.H. Finally, the AEC metric shall be calculated as a
weighted average of the rounded, rated power consumption values, based
on the expected time spent by the STB in the respective mode. DOE
believes including both the individual power consumption metrics and an
annualized metric provides both voluntary and State programs with the
flexibility they may wish to run their respective programs. However,
DOE reiterates that all representations of STB energy use must be made
in accordance with one of these four metrics resulting from the DOE
test procedure and sampling plan and as required by applicable State
and federal law.
While the draft CEA-2043 standard describes how to measure the
power in each mode of operation for a STB, it does not offer a way to
combine the values into a single AEC metric. Therefore, to create a
metric, DOE studied the ENERGY STAR test method for STBs. DOE believes
the TEC metric used by ENERGY STAR is conceptually similar to the AEC
metric that DOE is proposing in today's NOPR.
TEC is defined by ENERGY STAR as, ``a means for evaluating energy
efficiency through a calculation of expected energy consumption for a
typical user over a 1-year period, expressed in units of kilo-watt
hours per year (kWh/year)''. The TEC metric uses a table of time
coefficients to weight individual power measurements that are obtained
under the proposed test procedure. DOE proposes to use the same
approach, and to name the metric AEC. Like TEC, the AEC metric will
produce values measured in kWh/year. The equation below presents this
approach mathematically. Power values (Pi) are the rated values
obtained from the proposed measurement tests for each mode of STB
operation as discussed in sections III.G.5 through III.G.7 of the NOPR
and calculated using the sampling plan and rounding requirements
discussed in section III.H of the NOPR. Further, DOE proposes that the
time coefficients (Hi) shall be obtained from a table according to the
type of STB being tested, and the mode of STB operation.
[GRAPHIC] [TIFF OMITTED] TP23JA13.004
Where:
i = the mode of operation.
The main modes of operation measured by the proposed measurement
tests are:
PWATCH = the rated power consumption (in W) in on (watch
TV) mode,
PMULTI--STREAM = the rated power consumption (in W) in
the multi-stream test in on mode,
PSLEEP--MANUAL = the rated power consumption (in W) in
the manual sleep test in sleep mode,
PSLEEP--APD = the rated power consumption (in W) in the
APD test in sleep mode, for STB's with APD capability, and
POFF = the rated power consumption (in W) in off mode.
Inserting each of these modes into the above equation, results in
the equation below for AEC.
[GRAPHIC] [TIFF OMITTED] TP23JA13.005
[[Page 5100]]
To determine the time coefficients, DOE evaluated the ENERGY STAR
specification time coefficients as a possible source for the usage
weightings. Table 3 below lists the ENERGY STAR usage weightings. For
the sake of simplicity, the table excludes the ENERGY STAR weightings
for deep sleep, which DOE is not proposing to adopt. DOE does not
propose to adopt the ENERGY STAR deep sleep weightings because it
believes that the proposed power consumption in sleep mode would
capture the STB's deep sleep power as well, for any STBs that have deep
sleep capabilities. This is because DOE's proposed time period for the
sleep mode test is 4 to 8 hours, compared to ENERGY STAR's time period
of 5 minutes.

--------------------------------------------------------------------------------------------------------------------------------------------------------
The values in the ENERGY STAR specification do not directly map to
the modes DOE is proposing to test. In particular, there are no
separate record and playback tests in DOE's proposed test procedure
because these are bundled into a single multi-stream test as discussed
in section III.G.5.b of this NOPR. However, DOE is proposing to adopt
the ENERGY STAR weightings with the following changes: The 3 hour
record time is combined with the 2 hour playback time into a single 5
hour multi-stream test. Further, the ENERGY STAR specification does not
test the STB in off mode, and therefore does not assign any weighting
to the STB power consumption in off mode. While DOE is proposing a test
procedure to test the STB in off mode, it is not proposing any
weighting to the STB power consumption in off mode because consumers
typically do not turn off STBs. This is because often a STB cannot be
turned off. Further, for STBs that can be turned off, the time required
to start up a STB from off mode is lengthy and this discourages
consumer adoption to turn off the STB. Table 4 describes the weightings
DOE is proposing to use, which have been developed from the ENERGY STAR
weightings.

--------------------------------------------------------------------------------------------------------------------------------------------------------
While DOE is proposing the hour weightings listed in Table 4 above,
it also considered an alternative approach to estimate the time
coefficients for each mode by researching STB usage profiles. The time
coefficients from STB usage profiles is discussed in the following
paragraphs and presented in Table 5, but is not proposed in today's
NOPR. DOE is including this discussion to obtain stakeholders' feedback
on the different possibilities to determine the hour weightings and the
preferred approach that should be used for the calculation of AEC.
To determine STB usage profiles, DOE researched publically
available usage data. According to the most recent publically available
data from the Nielson Company, Americans spent 146.75 hours per month,
or approximately 5 hours per day, watching TV in the home.\31\ DOE
interpreted this to mean that the average STB spends 5 hours per day in
the on (watch TV) mode. DOE determined the number of hours a STB may be
in sleep mode by referring to survey data from Fraunhofer USA developed
for CEA. The survey indicates that 60 percent of STBs are turned
``off'' in tandem with the TV, while 40 percent are left on and run
continuously.\32\ Because a STB enters sleep mode when the power button
on the remote is pressed to turn it ``off'', DOE assumes that the 60
percent value refers to the number of STBs that are placed in sleep
mode. DOE estimates that the average STB spends virtually no time in
off mode.
---------------------------------------------------------------------------
\31\ State of the Media: U.S. Digital Consumer Report, Q3-Q4
2011, The Nielsen Company, p. 5.
\32\ Energy Consumption of Consumer Electronics in U.S. Homes in
2010, Fraunhofer USA, December 2011, p. 88. DOE's understanding is
that survey respondents interpreted the words ``off'' as a
colloquialism for sleep mode.
---------------------------------------------------------------------------
Using these data, DOE assumed that for STBs without APD or multi-
streaming capability, 40 percent remain in the on mode 24 hours per
day. The remaining 60 percent spend 5 hours in on mode, and 19 hours in
sleep mode. Time spent in APD and multi-streaming is zero. Therefore,
the average STB that does not have APD or multi-streaming capability,
is in on (watch TV) mode approximately 13 hours per day (40 percent x
24 hours + 60 percent x 5 hours) and sleep mode 11 hours per day (40
percent x 0 hours + 60 percent x 19 hours).
DOE researched market data from The Nielsen Company and found that
STBs with DVR capability spend approximately 5 hours viewing live
programming and approximately 2 hours recording content and playing it
back. For STBs with multi-streaming functionality, DOE assumed that of
the 5 hours that are spent viewing live programming, at least 3 hours
are viewed on a display device that is connected to a client. That is,
at least 3 hours of TV programming is viewed through the multi-
streaming functionality of the STB. While DOE does not have any market
data that describes the number of hours a STB streams content to a
client because multi-streaming is new functionality, it assumed that an
increasing amount of content shall be viewed through a client as the
technology progresses. Summing the 2 hours for recording and playing
back content with the 3 hours for viewing a channel through a client,
DOE
[[Page 5101]]
assumed that the multi-streaming functionality of a STB is exercised
approximately 5 hours per day and the on (watch TV) functionality is
exercised approximately 2 hours per day. Therefore, for STBs with
multi-streaming functionality, but no APD functionality, DOE assumed
that an average STB spends approximately 9 hours per day in on (watch
TV) mode (40 percent x 19 hours per day + 60 percent x 2 hours per
day); 5 hours per day in multi-streaming functionality; and 10 hours
per day in sleep mode (40 percent x 0 hours per day + 60 percent x 17
hours per day).
To determine the number of hours a STB with APD functionality would
spend in APD, DOE assumed that users that place their STB into sleep
mode manually when not being used do not get any benefit from APD. APD
functionality is only triggered if the STB is left in on mode for a
long period of time. DOE has assumed that, for STBs that would
otherwise be left in on mode all day, the presence of APD implied that
the STB enters sleep mode via APD for 12 hours per day. DOE does not
have data on the actual amount of time a STB is in sleep mode via APD
and requests stakeholders to submit data, if available. The assumption
of 12 hours per day is an estimate based on the expectation that the
STB is likely to enter sleep mode via APD during times of light TV use,
such as overnight and/or during mid-day. Based on these assumptions,
the average STB that has APD but not multi-streaming capabilities is in
APD approximately 5 hours per day (40 percent x 12 hours + 60 percent x
0 hours). Thus, DOE expects that STBs that enable APD by default would
be in sleep via APD 5 hours per day instead of being in the on (watch
TV) mode.
Finally, for STBs that are capable of both multi-streaming and APD
functionality and are placed into sleep mode, DOE again assumed that
the STB spends 5 hours per day in multi-streaming functionality and 2
hours per day in on (watch TV) mode. For STBs that always remain in on
mode, DOE assumed that the total time spent in APD is 10 hours. This
assumption is made based on the previous assumption that a STB that is
not capable of multi-streaming spends a total of 12 hours per day in
APD. That is, for STBs that are not placed into sleep mode manually,
the viewer watches content on a TV for approximately 5 hours per day
and of the remaining 19 hours, the STB spends approximately 12 hours
per day in APD. Therefore, for a STB that has multi-streaming
functionality, the viewer watches, records, or plays back content for
approximately 7 hours per day and of the remaining 17 hours, the STB
spends approximately 10 hours per day in APD. For STBs that are not
placed into sleep mode, the remaining 9 hours per day are spent in on
(watch TV) mode. That is, DOE assumed that an average STB spends
approximately 5 hours per day in on (watch TV) mode (40 percent x 9
hours per day + 60 percent x 2 hours per day); approximately 10 hours
per day in sleep mode (40 percent x 0 hours per day + 60 percent x 17
hours per day); approximately 5 hours in multi-streaming functionality;
and, approximately 4 hours per day in APD (40 percent x 10 hours per
day + 60 percent x 0 hours per day).
The resulting estimates for time coefficients are presented in
Table 5 below as alternative weightings to the proposed AEC metric.

DOE has proposed the hour weightings based on the ENERGY STAR
specification (Table 4) in today's NOPR and requests comment on the
proposed weightings and calculation of AEC. DOE also requests comment
on the alternative hour weightings (Table 5) that were developed by
researching STB usage profiles. In particular, DOE seeks feedback on
the time coefficients for AEC and whether one approach is preferred
over the other. The proposed AEC calculation is included in section 6
(Calculation of the Annual Energy Consumption of the Set-top Box) of
the proposed Appendix AA to Subpart B of 10 CFR Part 430).
IV. Procedural Issues and Regulatory Review
A. Review Under Executive Order 12866
The Office of Management and Budget has determined that test
procedure rulemakings do not constitute ``significant regulatory
actions'' under section 3(f) of Executive Order 12866, Regulatory
Planning and Review, 58 FR 51735 (Oct. 4, 1993). Accordingly, this
action was not subject to review under the Executive Order by the
Office of Information and Regulatory Affairs (OIRA) in the Office of
Management and Budget (OMB).
B. Review Under the Regulatory Flexibility Act
The Regulatory Flexibility Act (5 U.S.C. 601 et seq.) requires
preparation of an initial regulatory flexibility analysis (IFRA) for
any rule that by law must be proposed for public comment, unless the
agency certifies that the rule, if promulgated, will not have a
significant economic impact on a substantial number of small entities.
As required by Executive Order 13272, ``Proper Consideration of Small
Entities in Agency Rulemaking,'' 67 FR 53461 (August 16, 2002), DOE
published procedures and policies on February 19, 2003, to ensure that
the potential impacts of its rules on small entities are properly
considered during the DOE rulemaking process. 68 FR 7990. DOE has made
its procedures and policies available on the Office of the General
Counsel's Web site: http://energy.gov/gc/office-general-counsel.
DOE reviewed today's proposed rule under the provisions of the
Regulatory Flexibility Act (RFA) and the policies and procedures
published on February 19, 2003. The proposed rule prescribes the test
procedure to measure the power consumption of STBs in the on, sleep,
and off modes of operation and the calculation of an annualized energy
metric, AEC, as a weighted average of the individual power consumption
values. The initial regulatory flexibility analysis (IRFA) below
discusses the potential impacts of the test procedure on small
businesses and alternatives that would minimize the impact on small
businesses consistent with statutory objectives.
(1) Description of the reasons why action by the agency is being
considered.
A description of the reasons why DOE is considering this test
procedure are
[[Page 5102]]
stated elsewhere in the preamble and not repeated here.
(2) Succinct statement of the objectives of, and legal basis for,
the proposed rule.
The objectives of and legal basis for the proposed rule are stated
elsewhere in the preamble and not repeated here.
(3) Description of and, where feasible, an estimate of the number
of small entities to which the proposed rule will apply.
The Small Business Administration (SBA) has set a size threshold
for manufacturers of STBs that defines those entities classified as
``small businesses'' for the purposes of the RFA. DOE used the SBA's
small business size standards to determine whether any small
manufacturers of STBs would be subject to the requirements of the rule.
65 FR 30836, 30849 (May 15, 2000), as amended at 65 FR 53533, 53545
(Sept. 5, 2000) and codified at 13 CFR part 121. The size standards are
listed by North American Industry Classification System (NAICS) code
and industry description and are available at http://www.sba.gov/sites/default/files/files/Size_Standards_Table.pdf. DOE identified three
NAICS codes that apply to the manufacturers of STBs. The reasons for
selecting the following NAICS codes are discussed in further detail
below.
Radio and Television Broadcasting and Wireless Communications
Equipment Manufacturing are classified under NAICS 334220. SBA sets a
threshold of 750 employees or less for an entity to be considered a
small business for this category.
Audio and Video Equipment Manufacturing are classified under NAICS
334310. SBA sets a threshold of 750 employees or less for an entity to
be considered a small business for this category.
Cable and Other Subscription Programming are classified under NAICS
515210. The SBA threshold to qualify as a small business for this
category requires that the average annual receipts should be
$15,000,000 or less.
NAICS code 334220--Radio and Television Broadcasting and Wireless
Communications Equipment Manufacturing covers manufacturers of all
products except OTT STBs. Because some manufacturers of OTT STBs were
not listed under NAICS code 334220, DOE added consideration of small
business manufacturers listed under NAICS code 334310--Audio and Video
Equipment Manufacturing. Additionally, DOE included a search for small
businesses listed under NAICS code 515210--Cable and Other Subscription
Programming as some businesses in this category would also be subject
to today's rulemaking based on the definition of manufacturer discussed
in section III.D.3 of the NOPR.
To determine the number of small business manufacturers of STBs in
each NAICS code category, DOE compiled a preliminary list of potential
small business manufacturers of STBs by searching the Hoovers \33\ and
SBA databases. DOE confirmed if the companies were indeed small
businesses by reviewing the company Web site and/or calling the
company. Through this process, DOE identified five small business
manufacturers of STBs that manufacture STBs as defined in section
III.D.1. Of these five small business manufacturers, DOE identified two
small business manufacturers each under NAICS codes 334220 and 334310
and one small business manufacturer under NAICS code 515210. DOE
invites interested parties to comment on the expected number of small
business manufacturers of STBs.

---------------------------------------------------------------------------
(4) Description of the projected reporting, recordkeeping and other
compliance requirements of the proposed rule.
To determine the costs of the proposed test procedure on small STB
manufacturers, DOE estimated the cost of testing two STBs, the minimum
required sample size as discussed in section III.H of this NOPR. DOE
estimated a one time setup cost and a labor cost for performing the
tests. The labor cost of testing was then multiplied over the estimated
number of basic models produced by a small manufacturer. The estimated
cost of testing is discussed in further detail below.
For the initial setup for testing STBs, manufacturers require power
supply, power meter, cables to connect equipment, and hardware and
software instrumentation to measure the power consumption of the STB.
DOE estimated an approximate cost of $4,000 for the power supply and
$3,000 for the power meter. Further, the equipment cost for cables,
monitors, and software was estimated at approximately $3,100 for a
total initial setup cost of approximately $10,100.
DOE then estimated the time required to test each basic model of
STB based on conservative estimates of the duration proposed for each
test in the on, sleep, and off modes of operation. DOE's estimates
assume the longest proposed duration for the tests in sleep mode (that
is, 8 hours) and are as follows: 1 hour to set up and warm up the STB;
half an hour each to perform the on (watch TV) test and multi-stream
test of the STB in on mode; 8 hours for the manual sleep test; 12 hours
to test the STB in APD; and, half an hour to test the STB in off mode.
The total number of hours required to test one STB would be 22.5 hours.
For testing two STBs by an electronics engineer whose rate is $40.98
per hour,\34\ the labor cost would be approximately $1,850 for each STB
model. Estimates for the labor cost associated with testing are based
on feedback received during manufacturer interviews and Bureau of Labor
Statistics regarding average salaries for engineering staff. For the
five small business manufacturers of STBs that DOE identified, the
average number of models produced per manufacturer is four. Therefore,
for testing an average of four STB models, the testing cost in the
first year would be approximately $7,400. DOE expects this cost to be
lower in subsequent years because only new or redesigned STB models
would need to be tested.

(``Full-time civilian workers,'' mean and median hourly wages) <
http://bls.gov/ncs/ocs/sp/nctb0717.pdf.
---------------------------------------------------------------------------
DOE used company reports from Dunn & Bradstreet to estimate the
revenue for the five small business manufacturers identified. DOE then
applied an industry weighted average research and development estimate
to determine the budget for research and development for each small
business. The average revenue of the five small business manufacturers
is approximately $21.8M and the average budget for research and
development is approximately $2.02M, or 9.4 percent of revenues.
Relative to the average revenue and average research and development
budget per small business manufacturer, the total testing cost in the
first year is approximately $17,100. This cost is less than 0.1 percent
of the average revenue and approximately 0.1 percent of the average
research and development budget; that is, DOE believes the cost of
testing STBs is relatively small. Therefore, DOE has tentatively
concluded that testing costs would not be significant enough to pose a
substantial burden on small manufacturers. DOE requests comments on its
analysis of burden to small businesses for testing STBs according to
the proposed test procedure.
[[Page 5103]]
(5) Relevant Federal rules which may duplicate, overlap or conflict
with the proposed rule.
This proposed rule would, if adopted, establish a test procedure
for STBs. DOE is not aware of any other Federal rules that establish
such a procedure or would otherwise duplicate, overlap or conflict with
this test procedure.
(6) Description of any significant alternatives to the proposed
rule.
DOE considered a number of existing and under-development industry
standards that measure the energy consumption of STBs to develop the
proposed test procedure in today's rulemaking as discussed in section
III.C of the NOPR. Of the standards reviewed, today's proposed rule is
primarily based on the draft CEA-2043 standard because DOE believes it
provides most of the information required for testing STBs and expects
this standard to be adopted across industry to test the power
consumption of STBs. DOE seeks comment and information on the need, if
any, for alternative test methods that, consistent with the statutory
requirements, would reduce the economic impact of the rule on small
entities. DOE will consider any comments received regarding alternative
methods of testing that would reduce economic impact of the rule on
small entities. DOE will consider the feasibility of such alternatives
and determine whether they should be incorporated into the final rule.
C. Review Under the Paperwork Reduction Act of 1995
There is currently no information collection requirement related to
the test procedure for STBs. In the event that DOE proposes to require
the collection of information derived from the testing of STBs
according to this test procedure, DOE will seek OMB approval of such
information collection requirement.
DOE established regulations for the certification and recordkeeping
requirements for certain covered consumer products and commercial
equipment. 76 FR 12422 (March 7, 2011). The collection-of-information
requirement for the certification and recordkeeping was subject to
review and approval by OMB under the Paperwork Reduction Act (PRA).
This requirement was approved by OMB under OMB Control Number 1910-
1400. Public reporting burden for the certification was estimated to
average 20 hours per response, including the time for reviewing
instructions, searching existing data sources, gathering and
maintaining the data needed, and completing and reviewing the
collection of information.
As stated above, in the event DOE proposes to require the
collection of information derived from the testing of STBs according to
this test procedure, DOE will seek OMB approval of the associated
information collection requirement. DOE will seek approval either
through a proposed amendment to the information collection requirement
approved under OMB control number 1910-1400 or as a separate proposed
information collection requirement.
Notwithstanding any other provision of the law, no person is
required to respond to, nor shall any person be subject to a penalty
for failure to comply with, a collection of information subject to the
requirements of the PRA, unless that collection of information displays
a currently valid OMB Control Number.
D. Review Under the National Environmental Policy Act of 1969
In this proposed rule, DOE proposes a test procedure for STBs that
it expects will be used to develop and implement any future energy
conservation standard. DOE has determined that this rule falls into a
class of actions that are categorically excluded from review under the
National Environmental Policy Act of 1969 (42 U.S.C. 4321 et seq.) and
DOE's implementing regulations at 10 CFR part 1021. Specifically, this
proposed rule would propose a test procedure without affecting the
amount, quality or distribution of energy usage, and, therefore, would
not result in any environmental impacts. Thus, this rulemaking is
covered by Categorical Exclusion A5 under 10 CFR part 1021, subpart D,
which applies to any rulemaking that does not result in any
environmental impacts. Accordingly, neither an environmental assessment
nor an environmental impact statement is required.
E. Review Under Executive Order 13132
Executive Order 13132, ``Federalism,'' 64 FR 43255 (August 4, 1999)
imposes certain requirements on agencies formulating and implementing
policies or regulations that preempt State law or that have Federalism
implications. The Executive Order requires agencies to examine the
constitutional and statutory authority supporting any action that would
limit the policymaking discretion of the States and to carefully assess
the necessity for such actions. The Executive Order also requires
agencies to have an accountable process to ensure meaningful and timely
input by State and local officials in the development of regulatory
policies that have Federalism implications. On March 14, 2000, DOE
published a statement of policy describing the intergovernmental
consultation process it will follow in the development of such
regulations. 65 FR 13735. DOE has examined this proposed rule and has
determined that it would not have a substantial direct effect on the
States, on the relationship between the national government and the
States, or on the distribution of power and responsibilities among the
various levels of government. EPCA governs and prescribes Federal
preemption of State regulations as to energy conservation for the
products that are the subject of today's proposed rule. States can
petition DOE for exemption from such preemption to the extent, and
based on criteria, set forth in EPCA. (42 U.S.C. 6297(d)) No further
action is required by Executive Order 13132.
F. Review Under Executive Order 12988
Regarding the review of existing regulations and the promulgation
of new regulations, section 3(a) of Executive Order 12988, ``Civil
Justice Reform,'' 61 FR 4729 (Feb. 7, 1996), imposes on Federal
agencies the general duty to adhere to the following requirements: (1)
Eliminate drafting errors and ambiguity; (2) write regulations to
minimize litigation; (3) provide a clear legal standard for affected
conduct rather than a general standard; and (4) promote simplification
and burden reduction. Section 3(b) of Executive Order 12988
specifically requires that Executive agencies make every reasonable
effort to ensure that the regulation: (1) Clearly specifies the
preemptive effect, if any; (2) clearly specifies any effect on existing
Federal law or regulation; (3) provides a clear legal standard for
affected conduct while promoting simplification and burden reduction;
(4) specifies the retroactive effect, if any; (5) adequately defines
key terms; and (6) addresses other important issues affecting clarity
and general draftsmanship under any guidelines issued by the Attorney
General. Section 3(c) of Executive Order 12988 requires Executive
agencies to review regulations in light of applicable standards in
sections 3(a) and 3(b) to determine whether they are met or it is
unreasonable to meet one or more of them. DOE has completed the
required review and determined that, to the extent permitted by law,
the proposed rule meets the relevant standards of Executive Order
12988.
G. Review Under the Unfunded Mandates Reform Act of 1995
Title II of the Unfunded Mandates Reform Act of 1995 (UMRA)
requires
[[Page 5104]]
each Federal agency to assess the effects of Federal regulatory actions
on State, local, and Tribal governments and the private sector. Public
Law 104-4, sec. 201 (codified at 2 U.S.C. 1531). For a proposed
regulatory action likely to result in a rule that may cause the
expenditure by State, local, and Tribal governments, in the aggregate,
or by the private sector of $100 million or more in any one year
(adjusted annually for inflation), section 202 of UMRA requires a
Federal agency to publish a written statement that estimates the
resulting costs, benefits, and other effects on the national economy.
(2 U.S.C. 1532(a), (b)) The UMRA also requires a Federal agency to
develop an effective process to permit timely input by elected officers
of State, local, and Tribal governments on a proposed ``significant
intergovernmental mandate,'' and requires an agency plan for giving
notice and opportunity for timely input to potentially affected small
governments before establishing any requirements that might
significantly or uniquely affect small governments. On March 18, 1997,
DOE published a statement of policy on its process for
intergovernmental consultation under UMRA. 62 FR 12820; also available
at http://energy.gov/gc/office-general-counsel. DOE examined today's
proposed rule according to UMRA and its statement of policy and
determined that the rule contains neither an intergovernmental mandate,
nor a mandate that may result in the expenditure of $100 million or
more in any year, so these requirements do not apply.
H. Review Under the Treasury and General Government Appropriations Act,
1999
Section 654 of the Treasury and General Government Appropriations
Act, 1999 (Pub. L. 105-277) requires Federal agencies to issue a Family
Policymaking Assessment for any rule that may affect family well-being.
This rule would not have any impact on the autonomy or integrity of the
family as an institution. Accordingly, DOE has concluded that it is not
necessary to prepare a Family Policymaking Assessment.
I. Review Under Executive Order 12630
DOE has determined, under Executive Order 12630, ``Governmental
Actions and Interference with Constitutionally Protected Property
Rights'' 53 FR 8859 (March 18, 1988), that this regulation would not
result in any takings that might require compensation under the Fifth
Amendment to the U.S. Constitution.
J. Review Under Treasury and General Government Appropriations Act,
2001
Section 515 of the Treasury and General Government Appropriations
Act, 2001 (44 U.S.C. 3516 note) provides for agencies to review most
disseminations of information to the public under guidelines
established by each agency pursuant to general guidelines issued by
OMB. OMB's guidelines were published at 67 FR 8452 (Feb. 22, 2002), and
DOE's guidelines were published at 67 FR 62446 (Oct. 7, 2002). DOE has
reviewed today's proposed rule under the OMB and DOE guidelines and has
concluded that it is consistent with applicable policies in those
guidelines.
K. Review Under Executive Order 13211
Executive Order 13211, ``Actions Concerning Regulations That
Significantly Affect Energy Supply, Distribution, or Use,'' 66 FR 28355
(May 22, 2001), requires Federal agencies to prepare and submit to OMB,
a Statement of Energy Effects for any proposed significant energy
action. A ``significant energy action'' is defined as any action by an
agency that promulgated or is expected to lead to promulgation of a
final rule, and that: (1) Is a significant regulatory action under
Executive Order 12866, or any successor order; and (2) is likely to
have a significant adverse effect on the supply, distribution, or use
of energy; or (3) is designated by the Administrator of OIRA as a
significant energy action. For any proposed significant energy action,
the agency must give a detailed statement of any adverse effects on
energy supply, distribution, or use should the proposal be implemented,
and of reasonable alternatives to the action and their expected
benefits on energy supply, distribution, and use.
Today's regulatory action to establish a test procedure for
measuring the energy consumption of STBs is not a significant
regulatory action under Executive Order 12866. Moreover, it would not
have a significant adverse effect on the supply, distribution, or use
of energy, nor has it been designated as a significant energy action by
the Administrator of OIRA. Therefore, it is not a significant energy
action, and, accordingly, DOE has not prepared a Statement of Energy
Effects.
L. Review Under Section 32 of the Federal Energy Administration Act of
1974
Under section 301 of the Department of Energy Organization Act
(Pub. L. 95-91; 42 U.S.C. 7101), DOE must comply with section 32 of the
Federal Energy Administration Act of 1974, as amended by the Federal
Energy Administration Authorization Act of 1977. (15 U.S.C. 788; FEAA)
Section 32 essentially provides in relevant part that, where a proposed
rule authorizes or requires use of commercial standards, the notice of
proposed rulemaking must inform the public of the use and background of
such standards. In addition, section 32(c) requires DOE to consult with
the Attorney General and the Chairman of the Federal Trade Commission
(FTC) concerning the impact of the commercial or industry standards on
competition.
The proposed rule incorporates the following commercial standards:
CEA-770.3-D, ``High Definition TV Analog Component Video Interface;''
HDMI Specification Version 1.0, ``High-Definition Multimedia Interface
Specification;'' ISO/IEC 7816-12, ``Identification cards--Integrated
circuit cards--Part 12: Cards with contacts--USB electrical interface
and operating procedures;'' ANSI/SCTE 28 2007, ``HOST-POD Interface
Standard;'' ANSI/SCTE 55-1 2009, ``Digital Broadband Delivery System:
Out of Band Transport Part 1: Mode A;'' and ANSI/SCTE 55-2 2008,
``Digital Broadband Delivery System: Out of Band Transport Part 2: Mode
B''. These standards would be incorporated by reference in 10 CFR 430.3
(Materials incorporated by reference). The incorporated standards are
respectively used to describe Component Video, HDMI, POD, smart card,
and equipment that communicate with the STB. The Department has
evaluated these standards and is unable to conclude whether these
industry standards fully comply with the requirements of section 32(b)
of the FEAA, (i.e., that they were developed in a manner that fully
provides for public participation, comment, and review). DOE will
consult with the Attorney General and the Chairman of the FTC
concerning the impact of these test procedures on competition, prior to
prescribing a final rule.

E. Issues on Which DOE Seeks Comment
Although DOE welcomes comments on any aspect of this proposal, DOE
is particularly interested in receiving comments and views of
interested parties concerning the following issues:
1. DOE requests comment on narrowing the scope of today's
rulemaking to STBs and excluding network equipment. See section III.B
for further detail.
2. DOE requests comment on using the draft CEA-2043 standard as the
basis for today's proposed test procedure for STBs. See section III.C
for further detail.
3. DOE requests comment on the proposed definition of STBs. In
particular, DOE requests comment about whether the proposed definition
is specific enough to exclude non-STB devices such as gaming consoles
and smartphones, yet broad enough to cover traditional STBs and newer
boxes. DOE also requests comment on the proposed definitions for direct
video connection, HDMI, Component Video, S-Video, and Composite Video.
See section III.D.1 for further detail.
4. DOE invites comment on the discussion of basic model as it
pertains to the STB rulemaking. See section III.D.2 for further detail.
5. DOE invites interested parties to comment on the proposed
definitions for the STB test procedure NOPR including the definitions
for content provider and multi-stream and clarifying information
included for the definitions of DVR, display device, and HNI. For the
definition of DVR, DOE requests comment on the proposed approach of not
testing STBs with external storage as a DVR. If DOE does consider
testing the STB with an external storage device as DVR in response to
comments, DOE specifically requests comments on the proper external
storage device to use. See section III.D.4 for further detail.
6. DOE invites interested parties to comment on the proposed
definitions of on, sleep, and off modes of operation of a STB. In
particular, DOE requests comment, and data, if available, on the
proposed requirement to transition from sleep mode to on mode within 30
seconds, or whether a different maximum allowable transition time
should be considered. See section III.D.5 for further detail.
7. DOE requests comment on the proposed requirements for setting up
the STB as installed in a consumer's home for testing. See section
III.E.1 for further detail.
8. DOE requests comment on the proposed test room conditions for
testing STBs, including air temperature, air speed, and thermally non-
conductive test surface requirements. In particular, DOE invites
interested parties to comment on the proposed air speed requirement of
0.5 m/s and whether this requirement should be relaxed to a higher
value or removed altogether. See section III.E.2 for further detail.
9. DOE invites interested parties to comment on the proposed input
power requirements for testing STBs. See section III.F.1 for further
detail.
10. DOE requests comment on the proposed requirements for the
accuracy of measuring the power consumption of STBs. See section
III.F.2 for further detail.
11. DOE invites interested parties to comment on the recommended
test equipment to measure the AC line current, voltage, and frequency.
See section III.F.3 for further detail.
12. DOE requests comment on the proposed power meter
instrumentation requirements such as, crest factor, bandwidth,
frequency response, and sampling interval requirements. See section
III.F.4 for further detail.
13. DOE requests comment on the proposed calibration requirements
for testing STBs. See section III.F.5 for further detail.
14. DOE requests comment on the proposed requirements for testing
STBs that require an HNI connection. Particularly, DOE requests comment
on the proposed order in which HNI connections shall be used, that is,
MoCA, followed by HPNA, followed by Wi-Fi, and finally any other
connection. DOE also requests comment about whether there are any
additional HNI connections that should be included and the order of
preference in which they should be included. See section III.F.6.a for
further detail.
15. DOE invites interested parties to comment on the proposed setup
requirements for STBs requiring broadband service. Particularly, DOE
requests comment on the clarification that a service provider network
connection should take precedence over a broadband connection for STBs
that are designed to operate on either connection. See section
III.F.6.b for further detail.
16. DOE requests comment on the proposed exclusion of external
equipment power consumption from the power consumption of the STB
itself. Further, if stakeholders suggest that the power consumption of
external equipment be tested and measured, DOE requests comment on the
test method and standard configuration that should be used to test the
external equipment. See section III.F.6.c for further detail.
17. DOE requests comment on the proposed exclusion of power
consumption of the input signal equipment from the power consumption of
the STB. Further, DOE requests comment on the clarification that such
equipment should not supply any power to the STB. DOE also requests
feedback on the potential use of a DC block to prevent power transfer
to and from any input signal equipment. Finally, if stakeholders
indicate that this equipment should be tested and the power consumption
be measured, DOE requests comment on the test method and standard
configuration that should be used to test this equipment. See section
III.F.6.d for further detail.
18. DOE invites interested parties to comment on the proposed
requirements for service provider network
[[Page 5107]]
connection. In particular, DOE requests comment and data, if available,
about whether the power consumption of a STB is similar on a live
network versus a closed network. See section III.F.6.e for further
detail.
19. DOE requests comment on the proposed warm-up time for
stabilizing the STB. See section III.G.1 for further detail.
20. DOE invites interested parties to comment on all aspects of the
proposed configuration for testing STBs in the on, sleep, and off modes
of operation. DOE is especially interested in receiving comments on the
proposed connections for the test configuration. DOE also invites
comments on the proposed order of preference for connecting a display
device to the STB. See section III.G.2 for further information.
21. DOE requests comment on the proposed requirements for streaming
an appropriate SD or HD stream to a display device. DOE also invites
comment on the proposed requirement to record content on a DVR
integrated into the STB. Finally, DOE requests comment on the proposed
requirements to stream content to a connected client. Specifically, DOE
requests comment on the proposed hierarchy of content to stream to a
connected client, which is a recorded stream followed by a channel. See
section III.G.3 for further detail.
22. DOE requests comment on the proposed methods to determine the
average power consumption of the STB in each mode of operation. See
section III.G.4 for further detail.
23. DOE invites comment on all aspects of the proposed approach for
testing the STB in the on mode including the proposed time period of 2
minutes for all tests in the on mode. The on mode measurement test
includes the on (watch TV) test and multi-stream test. See section
III.G.5 for further detail.
24. DOE requests comment on the proposed method for the on (watch
TV) test. In particular, DOE requests comment on the approach of using
both, an SD and HD stream for testing HD STBs. DOE also requests
interested parties to comment, and provide data if available, on the
percentage of streams that are available in SD and HD for HD STBs, and
whether the proposed equation for calculating PWATCH should
be changed. See section III.G.5.a for further detail.
25. DOE requests comment on the approach of using a single multi-
stream test as well as the test procedure to test STBs with multi-
streaming capability. DOE is especially interested in receiving
comments on the proposed priority list for enabling streams for testing
STBs with multi-streaming capability. DOE also seeks feedback on
whether the number of additional streams that should be enabled should
be other than three and the reasons for enabling a different number of
streams. DOE requests comment on the possibility of including a maximum
power test, which would test the STB such that the maximum number of
streams is enabled. If included, DOE requests comment on the weighting
that should be applied for the maximum streaming test in the
calculation of the AEC. See section III.G.5.b for further detail.
26. DOE requests comment on all aspects of the proposed
specification for setting up STBs for testing in sleep mode. In
particular, DOE invites comment on the proposed duration (4 to 8 hours
unless network activities prompt a longer time period) over which the
power consumption of the STB shall be measured and averaged, and
whether this duration should be increased or decreased to better
represent the STB power consumption in sleep mode. See section III.G.6
for further detail.
27. DOE also requests comment on the proposed scheduled recording
requirement prior to placing the STB in sleep mode to measure its power
consumption. DOE requests interested parties to provide data, if
available, on the variation in power consumption of a STB when a
recording is scheduled versus when it is not scheduled. See section
III.G.6 for further detail.
28. DOE invites interested parties to comment on all aspects of the
proposed method to address network initiated actions. DOE requests
comment and data, if available, on the approach proposed in today's
NOPR, the approaches that were considered but have not been proposed,
as well as any other approach that stakeholders believe would best
capture the transition of the STB from sleep mode to on mode due to
network initiated activities. See section III.G.6 for further detail.
29. DOE invites comments on the proposed requirements for testing
STBs in manual sleep mode. See section III.G.6.a for further detail.
30. DOE requests comment on the proposed test for determining the
STB power consumption in APD. In particular, DOE requests comment and
data, if available, on the time required to transition to sleep mode
from on mode and whether this time period should be set at a default
value of 4 hours or adjusted during testing. DOE also requests comment
on potential methods to scale APD and the advantages and disadvantages
of scaling the power consumption in APD. Finally, DOE requests comment
on potential methods to account for a scaling APD value in the AEC
metric. See section III.G.6.b for further detail.
31. DOE invites interested parties to comment on the proposed
requirements for testing STBs in off mode. See section III.G.7 for
further detail.
32. DOE requests comment on the proposed sleep to on mode
transition time measurement test. See section III.G.8 for further
detail.
33. DOE requests comment on the proposed sampling plan and rounding
requirements for making representations of the STB power consumption in
each mode of operation. DOE also requests comment on proposed rounding
requirements for AEC, which is calculated from the rated power
consumption values. See section III.H for further detail.
34. DOE requests comment on the proposed calculation of the AEC
metric for determining the annual energy consumption of the STB. DOE
requests comment on the proposed hour weightings that were developed
based on the ENERGY STAR specification or whether the alternate hour
weightings should be considered instead. DOE also invites comment and
data, if available, on the time coefficients for each mode of operation
to calculate the AEC. See section III.I for further detail.
35. DOE requests comment on the analysis of the burden to small
businesses for testing STBs according to the proposed test procedure.
DOE also requests comment on the expected number of small business
manufacturers of STBs. See section IV.B for further detail.
36. DOE requests additional information and comment for the
development of a test procedure for LNBs, ONTs, ODUs, or other
infrastructure devices and the standard configuration in which these
devices should be tested, if stakeholders support developing a test
procedure for them. See section III.B for further detail.

7. Appendix AA to Subpart B of Part 430 is added to read as follows:
Appendix AA to Subpart B of Part 430--Uniform Test Method for Measuring
the Energy Consumption of Set-top Boxes
1. Scope: This appendix covers the test requirements to measure
the power consumption of set-top boxes (STBs) in the on, sleep, and
off modes and provides the method to calculate the annual energy
consumption (AEC) of the STB.
2. Definitions
2.1. ANSI means the American National Standards Institute.
2.2. Auto power down (APD) means a STB feature that monitors
parameters correlated with user activity or viewing. If the
parameters collectively indicate that no user activity or viewing is
occurring, the APD feature enables the STB to transition to sleep or
off mode.
2.3. Client means any device (example: STB, thin-client STB,
smart television (TV), mobile phone, tablet, or personal computer)
that can receive content over a home network interface (HNI).
2.4. Content provider means an entity that provides video
programming content.
2.5. Crest factor means the ratio of the peak current to the
root-mean-square (rms) current.
2.6. Digital video recorder (DVR) means a STB feature that
records television signals on a hard disk drive (HDD) or other non-
volatile storage device integrated into the STB. A DVR often
includes features such as: Play, Record, Pause, Fast Forward (FF),
and Fast Rewind (FR). STBs that support a service provider network-
based ``DVR'' service are not considered DVR STBs for purposes of
this test procedure. The presence of DVR functionality does not mean
the device is defined to be a STB.
2.7. Display device means a device (example: TV, Computer
Monitor, or Portable TV) that receives its content directly from a
STB through a video interface (example: High-Definition Multimedia
Interface (HDMI), Component Video, Composite Video, or S-Video), not
through an HNI, and displays it for viewing.
2.8. Harmonic means a component of order n of the Fourier series
that describes the periodic current or voltage (where n is an
integer greater than 1).
2.9. High definition test stream (HD) means video content
delivered to the STB by the content provider to produce a minimum
output resolution of 1280 x 720 pixels in progressive scan mode at a
minimum frame rate of 59.94 frames per second (fps) (abbreviated
720p60) or a minimum output resolution of 1920 x 1080 pixels in
interlaced scan mode at 29.97 fps (abbreviated 1080i30).
2.10. Home network interface (HNI) means an interface with
external devices over a local area network (example: Institute of
Electrical and Electronics Engineers (IEEE) 802.11 (Wireless-
Fidelity or Wi-Fi), Multimedia over Coax Alliance (MoCA), HomePNA
alliance (HPNA), IEEE 802.3, HomePlug AV) that is capable of
transmitting video content.
2.11. IEC means International Electrotechnical Commission.
2.12. ISO means the International Organization for
Standardization.
2.13. Low noise block-downconverter (LNB) means a combination of
low-noise amplifier, block-downconverter and intermediate
frequencies (IF) amplifier. It takes the received microwave
transmission, amplifies it, down-converts the block of frequencies
to a lower block of IF where the signal can be amplified and fed to
the indoor satellite TV STB using coaxial cable.
2.14. Multi-stream means a STB feature that may provide
independent video content to one or more clients, one or more
directly connected TVs, or a DVR.
2.15. Outdoor unit (ODU) means satellite signal reception
components including: a receiving dish, one or more LNBs, and
imbedded or independent radio frequency (RF) switches, used to
distribute a satellite service provider network to consumer
satellite STBs.
2.16. Point of deployment (POD) module means a plug-in card that
complies with the ANSI/SCTE 28 (incorporated by reference; see Sec.
430.3) interface and is inserted into a digital-cable-ready device
to enable the decryption of services and provide other network
control functions.
2.17. Power mode means a condition or state of a device that
broadly characterizes its capabilities, power consumption, power
indicator coding, and responsiveness to input.
2.18. Principal STB Function means functions necessary for
selecting, receiving, decoding, decompressing, or delivering video
content to a display device, DVR, or client. Monitoring for user or
network requests is not considered a principal STB function.
2.19. Satellite STB means a STB that receives and decodes video
content as delivered from a service provider satellite network.
2.20. SCTE means The Society of Cable Telecommunications
Engineers, Inc.
2.21. Service provider means a business entity that provides
video content, a delivery network, and associated installation and
support services to subscribers with whom it has an ongoing
contractual relationship.
2.22. Smart Card means a plug-in card that complies with ISO/IEC
7816-12 (incorporated by reference; see Sec. 430.3) and is inserted
into a satellite STB to enable the decryption of services and
provide other network control functions.
2.23. Standard definition test stream (SD) means video content
delivered to the STB by the content provider to produce an output
resolution of 640 x 480 pixels in interlaced scan mode at minimum
frame rate of 29.97 fps (abbreviated 480i30).
2.24. Thin-client STB means a STB that can receive content over
an HNI from another STB, but is unable to interface directly to the
service provider network.
2.25. Definitions of Power Modes.
2.25.1. On mode means the STB is connected to a mains power
source. At least one principal STB function is activated and all
principal STB functions are provisioned for use. The power
consumption in on mode may vary based on specific use and
configuration.
2.25.2. Sleep mode means a range of reduced power states where
the STB is connected to a mains power source and is not providing
any principal STB function. The STB may transition to on or off mode
due to user action, internal signal, or external signal. The power
consumed in this mode may vary based on specific use or
configuration. If any principal STB function is activated while
operating in this mode, the STB is assumed to transition to on mode.
Monitoring for user or network requests is not considered a
principal STB function. The STB shall be able to transition from
this mode to on mode within 30 seconds to be considered in sleep
mode.
2.25.3. Off mode means the STB is connected to a mains power
source, has been de-activated, and is not providing any function.
The STB requires a user action to transition from this mode to on or
sleep mode.
Note: Sleep and off modes may not be available on all STBs.
3. Test Conditions
3.1. Set-top Box Settings.
3.1.1. For STBs that require subscription to a service, select
the simplest available video subscription that supports all
functionality specified in this test procedure (example: HD
streaming, multi-stream, DVR, etc.). That is, select a subscription
with TV services only; services with non-video capability, such as
telephony, shall not be selected.
3.1.2. If the STB can be installed by the consumer per the
manufacturer's instructions without the service of a technician,
then install and setup the STB according to the instructions
provided in the user manual shipped with the unit. Setup the STB
using only those instructions in the user manual. Setup is
considered complete once these instructions are followed.
3.1.3. If the STB must be installed by a technician per the
manufacturer's instructions, then it shall be setup as installed by
the technician using this test procedure. All steps that a
technician would follow when installing a STB for use in a consumer
residence should be followed. Information about each of the steps
that were performed to setup the STB by a technician shall be
recorded and maintained by the manufacturer pursuant to 10 CFR Part
429.71.
3.2. Test Room. Tests shall be carried out in a room with the
following requirements:
3.2.1. The air speed surrounding the STB shall be less than or
equal to 0.5 meters per second (m/s).
3.2.2. The ambient temperature shall be maintained at 23 [deg]C
5 [deg]C for the duration of the test.
3.2.3. The STB shall be tested on a thermally non-conductive
surface.
[[Page 5110]]

4.1. Test Voltage. STBs intended to be powered by the
alternating current (AC) mains shall utilize a power source with the
following requirements:
4.1.1. An input voltage of 115 volts 1 percent.
4.1.2. A frequency of 60 hertz 1 percent.
4.1.3. Total harmonic distortion of the supply voltage shall not
exceed 2 percent up to and including the 13th harmonic.
4.1.4. The peak value of the test voltage shall be between 1.34
and 1.49 times its rms value. That is, the crest factor shall be
between 1.34 and 1.49.
4.2. Measurement Accuracy. Power measurements of 0.5 watt (W) or
greater shall be made with an uncertainty of less than or equal to 2
percent at the 95 percent confidence level. Power measurements of
less than 0.5 W shall be made with an uncertainty of less than or
equal to 0.01 W at the 95 percent confidence level. The power
measurement instrument shall have a resolution of:
4.2.1. 0.01 W or better for power measurements of 10 W or less;
4.2.2. 0.1 W or better for power measurements of greater than 10
W and up to 100 W; and
4.2.3. 1 watt or better for power measurements of greater than
100 W.
For equipment connected to more than one phase, the power
measurement instrument shall be equipped to measure the total power
of all of the phases connected.
4.3. Test Equipment. The following should be considered when
selecting test equipment:
4.3.1. An oscilloscope with a current probe to monitor AC line
current waveform, amplitude, and frequency.
4.3.2. A true rms voltmeter to verify voltage at the input of
the STB.
4.3.3. A frequency counter to verify frequency at the input of
the STB.
4.4. True Power Wattmeter.
4.4.1. Crest factor. A true power wattmeter shall be used and
shall have:
4.4.1.1. Accuracy and resolution in accordance with section 4.2.
4.4.1.2. Sufficient bandwidth.
4.4.1.3. A crest factor rating that is appropriate for the
waveforms being measured and capable of reading the available
current waveform without clipping the waveform. The peak of the
current waveform measured during sleep and on modes for the STB
shall be used to determine the crest factor rating and the current
range setting. The full-scale value of the selected current range
multiplied by the crest factor for that range shall be at least 15
percent greater than the peak current to prevent measurement error.
4.4.2. Bandwidth. The current and voltage signal shall be
analyzed to determine the highest frequency component (that is,
harmonic) with a magnitude greater than 1 percent of the fundamental
frequency under the test conditions. The minimum bandwidth of the
test instruments shall be determined by the highest frequency
component of the signal.
4.4.3. Frequency response. A wattmeter with a frequency response
of at least 3 kilo-hertz (kHz) shall be used in order to account for
harmonics up to the 50th harmonic.
4.4.4. Sampling Interval. The wattmeter shall be capable of
sampling at intervals less than or equal to 1 second.
Note: Electronic equipment can cause harmonic waveforms that
lead to inaccuracies in power measurements.
4.5. Calibration. Test instruments shall be calibrated annually
to traceable national standards to ensure that the limits of error
in measurement are not greater than 0.5 percent of the
measured value over the required bandwidth of the output.
4.6. Network Setup.
4.6.1. Home Network Connection. STB configurations that require
the use of a home network (example: thin-client STB) shall use the
HNI option according to the following order of preference. The first
available connection that the STB supports shall be used:
1. Multimedia over Coaxial Alliance (MoCA);
2. Home PNA Alliance (HPNA);
3. Wi-Fi (802.11); or
4. Other HNI connection.
4.6.2. Broadband Service. If the STB includes an HNI, and the
HNI shall be connected to broadband service for operation of a
principal STB function, it shall be tested while connected to a
broadband network. Broadband performance criteria (that is, download
speed, upload speed, latency, etc.) shall meet the specified
requirements of the STB to fulfill the principal STB functions. For
STBs designed to operate both with a broadband connection and a
service provider network connection, the service provider connection
takes precedence, and the broadband connection shall only be made if
the STB requires it for operating a principal STB function.
4.6.3. Service Provider Network Distribution Equipment. If the
STB requires the use of external equipment to connect the service
provider network to the STB, then the power consumption of this
equipment shall not be included as part of the STB power
measurement. This includes required service provider network
distribution equipment such as network gateways, network routers,
network bridges, optical network terminals (ONTs), wireless access
points, media extenders, or any other device required for
distribution of a service provider network to the STB.
4.6.4. Input Signal Equipment. When an ODU, over the air (OTA)
antenna amplifier, cable TV (CATV) distribution amplifier, or
similar signal equipment is required and the power for that
equipment is supplied from the STB, then the measurement shall not
include the power consumption of that equipment, unless the
equipment cannot be powered from a source other than the STB. If the
signal equipment cannot be powered from a source other than the STB,
then the power for these equipment shall be included in the STB
power consumption measurement and the signal equipment should be
configured in its lowest power consuming mode. However, if the
signal equipment can be powered from a source other than the STB,
then it shall be powered from another source, and such equipment
shall not deliver any power to the connected STB.
4.6.5. Service Provider Network Connection. The STB shall be
tested with a specific service provider network or a simulated
environment verified by the service provider, and the STB shall be
configured to simulate a subscriber operating environment. This
shall include the ability to access the full services of the service
provider network required by the STB, such as content, program
guides, software updates, and other STB features that require
network services to fully function. If the STB requires a POD or
Smart Card, then it shall be connected, authorized, and operational.
Essential STB peripheral devices, required for the normal operation
of the STB, such as a Universal Serial Bus (USB) powered external
HDD, a USB powered Wi-Fi dongle, or a USB powered OTA receiver,
shall be connected and operational. Optional peripheral devices
shall not be connected to the STB. The STB may be tested in a
laboratory environment containing control equipment comparable to a
live service provider system. For example, a cable STB may be tested
in a laboratory that contains a conditional access system, the
appropriate equipment to communicate with the STB (example: ANSI/
SCTE 55-1 (incorporated by reference; see Sec. 430.3) or ANSI/SCTE
55-2 forward and reverse data channel hardware or data-over-cable
service interface specification (DOCSIS) infrastructure), and the
appropriate interconnections (example: Diplexers, splitters, and
coaxial cables).
5. Test Procedure for Determining the Power Consumption of the
Set-top Box in different Modes of Operation
5.1. Set-top Box Warm-up. Allow the STB to operate in on mode
while receiving and decoding video for at least 15 minutes so the
STB can achieve stable condition.
5.2. Test Configuration Information.
5.2.1. The display device and client setup is described in Table
1 of this appendix. Based on the capability of the STB, the
appropriate number of display devices and clients shall be
connected.

5.2.2. Connecting to a Display Device. The STB shall be
connected to the number of display devices required based on the
setup requirements specified in Table 1. The following order of
preference shall be used to connect each display device to the STB.
The first available connection that the STB supports shall be used:
1. HDMI
2. Component Video
3. S-Video
4. Composite Video
5. Other video interface
5.2.3. Connecting to a Client. The STB shall be connected to the
number of clients required based on the setup requirements specified
in Table 1. An HNI connection shall be used to connect the client to
the STB. The order of preference in which an HNI connection shall be
selected is specified in section 4.6.1.
5.3. Test Conduct.
The following section is provided as guidance when conducting
the various on, sleep, and off mode tests. When multiple streams are
enabled, different content shall be selected to output to a display
device, record on a DVR integrated into the STB, and stream to a
connected client.
5.3.1. Output to a Display Device. For tests requiring output to
a display device, a channel shall be selected and viewed on the
connected display device(s) as required by the test configuration.
For STBs that do not support channels, an appropriate SD or HD test
stream shall be selected and the content shall be viewed as
indicated. If more than one display device is connected to the STB
based on the test configuration from Table 1, then the content
outputted on each display device shall be different.
5.3.2. Recording for a STB with DVR capability. For tests that
require recording on a DVR, a channel shall be selected using a
connected display device or a client and the program shall be
recorded. If more than one recording is enabled on a DVR that is
integrated into the STB, the content for each recording shall be
different.
5.3.3. Streaming to a Connected Client. The content streamed to
a client shall be selected in the following order of preference
depending on the number of streams enabled. The first available
stream that is supported by each connected client shall be enabled
and the content on each stream shall be different.
5.3.3.1. Stream with recorded content. That is, previously
recorded content shall be viewed on a display device connected to a
client.
5.3.3.2. Stream with channel content. That is, a channel (SD
stream for an SD client and HD stream for an HD client) shall be
viewed on the connected display device. For clients that do not
support channels, select an appropriate SD or HD test stream and
view the content as indicated.
5.3.3.3. Other streaming option. If the streams from sections
5.3.3.1 and 5.3.3.2 are not supported, use another stream that is
available.
5.4. Calculation of Average and Rated Power Consumption.
5.4.1. For all tests in the on, sleep, and off modes (sections
5.5, 5.6, and 5.7), the average power shall be calculated using one
of the following two methods:
5.4.1.1. Record the accumulated energy (Ei) in kilo-
watt hours (kWh) consumed over the time period specified for each
test (Ti). The average power consumption is calculated as
Pi = Ei/Ti.
5.4.1.2. Record the average power consumption (Pi) by
sampling the power at a rate of at least 1 sample per second and
computing the arithmetic mean of all samples over the time period
specified for each test (Ti).
5.4.2. The rated power consumption in the on, sleep, and off
modes shall be determined as follows:
5.4.2.1. Apply the sampling and statistical requirements
described in 10 CFR part 429.55 to the average power consumption
values in each mode of operation.
5.4.2.2. The resulting rated power consumption value, for each
mode of operation, shall be rounded according to the accuracy
requirements specified in section 4.2.
5.5. On Mode Power Measurement.
5.5.1. The time period for each test in the on mode (sections
5.5.2 and 5.5.3), TON, is 2 minutes.
5.5.2. On (Watch TV). The on (watch TV) test shall be performed
on all STBs as follows.
5.5.2.1. On (Watch TV SD).
5.5.2.1.1. Configure the STB as specified in section 5.2.
5.5.2.1.2. Of all the connections to the STB, only one stream
shall be enabled and shall stream to a display device. No additional
streams shall be sent to other connected display devices and/or
clients.
5.5.2.1.3. If supported, select an SD channel and view on the
connected display device. For STBs using a content provider that
does not support channels, select an appropriate SD test stream and
view the content as indicated.
5.5.2.1.4. Begin on mode power consumption measurement and
record the average power consumption with the SD source content for
2 minutes as PWATCH--SD.
5.5.2.2. On (Watch TV HD).
5.5.2.2.1. If the STB supports HD streaming, repeat the test in
section 5.5.2 using HD content instead of SD content and record this
value as PWATCH--HD.
5.5.2.3. Calculation of PWATCH. Compute PWATCH according to the
following equation:
[GRAPHIC] [TIFF OMITTED] TP23JA13.013
Where:
PWATCH = the power consumption (in watts (W)) in on
(watch TV) mode,
PWATCH--SD = the power consumption (in W) in on (watch TV
SD) mode when an SD test stream is used, and
PWATCH--HD = the power consumption (in W) in on (watch TV
HD) state when an HD test stream is used.
5.5.3. Multi-stream.
5.5.3.1. Perform this test only if the STB supports multi-
streaming as defined in section 2.14.
5.5.3.2. Configure the STB as specified in section 5.2 of this
appendix. Table 2 of this
[[Page 5112]]
appendix describes how to setup the multi-stream test. Choose the
highest priority (smallest number option) that the STB supports.

5.5.3.3. All streams required for the feasible STB configuration
shall be enabled using appropriate content as described in section
5.3 of this appendix. If the STB or connected client(s) support HD
streaming, an HD stream shall be used, otherwise an SD stream shall
be used.
5.5.3.4. Begin the multi-stream mode power consumption
measurement and record the average power consumption for 2 minutes
as PMULTI--STREAM.
5.6. Sleep Mode Power Measurement.
5.6.1. Only run the test for each mode if the STB supports this
functionality, as defined in section 2.25.2. If the STB cannot be
placed in sleep mode as defined in section 2.25.2 using a remote
control, then this test shall be skipped.
5.6.2. The time period for each test in the sleep mode (sections
5.6.7 and 5.6.8 of this appendix), TSLEEP, shall be
between 4 to 8 hours. The time period shall be extended beyond 8
hours only if required as described in section 5.6.4 of this
appendix.
5.6.3. Assure no recording events are scheduled over the entire
duration of the test, including the time prior to transitioning to
sleep mode. If the STB is capable of scheduling a recording,
schedule a recording 24 or more hours into the future.
5.6.4. Assure no service provider network initiated actions
requiring a transition to on mode occur during the 4 to 8 hour time
period that the STB is in sleep mode (example: Content downloads or
software updates). If a service provider network initiated activity
cannot be disabled, then this shall be monitored as follows:
5.6.4.1. The power consumption shall be sampled at a rate of at
least 1 sample per second.
5.6.4.2. For input powers less than or equal to 1 W, a linear
regression through all power readings shall have a slope of less
than 10 milli-watts per hour (mW/h). If the slope of the linear
regression is equal to or greater than 10 mW/h the test shall either
be restarted or extended until a slope of less than 10 mW/h is
achieved.
5.6.4.3. For input powers greater than 1 W, a linear regression
through all power readings shall have a slope of less than 1 percent
of the measured input power per hour. If the slope of the linear
regression is equal to or greater than 1 percent the test shall
either be restarted or extended until a slope of less than 1 percent
is achieved.
5.6.4.4. If the test is extended beyond 8 hours to achieve the
desired condition, the average power consumption over the entire
test duration shall be reported for PSLEEP--MANUAL and
PSLEEP--APD and these values shall be used to determine
the AEC.
5.6.5. Assure no local area network initiated actions requiring
a transition to on mode are scheduled during the 4 to 8 hour time
period that the STB is in sleep mode (example: Mobile applications
or other network devices requesting service).
5.6.6. Configure the STB as specified in section 5.2 of this
appendix.
5.6.7. Manual Sleep Test.
5.6.7.1. If the STB does not support sleep mode, then set
PSLEEP--MANUAL equal to PWATCH.
5.6.7.2. For STBs that are capable of transitioning to sleep
mode, operate the STB in the multi-stream test configuration
(section 5.5.3 of this appendix) for at least 5 minutes if the STB
supports multi-streaming. If the STB does not support multi-
streaming, operate the STB in the on (watch TV) configuration
(section 5.5.2 of this appendix) for at least 5 minutes.
5.6.7.3. Momentarily (<1 second) press the ``Power'' button on
the remote for the STB, and each locally connected display device
and client, to place the STB, and each locally connected display
device and client, into sleep mode as defined in section 2.25.2.
Some STBs may require a short period of time before they actually
enter a lower power consumption mode.
5.6.7.4. Do not use (or move) the STB remote control after
section 5.6.7.3 of this appendix.
5.6.7.5. Ensure that the STB and each locally connected client
has entered sleep mode by verifying no channel viewing or recording
is supported on the STB and client(s). That is, there shall be no
video output on the connected display device(s) from the STB and any
locally connected clients.
5.6.7.6. Begin manual sleep mode power consumption measurement
and record the average power consumed as PSLEEP--MANUAL
over the time period as determined in section 5.6.2 of this
appendix.
5.6.8. Auto Power Down (APD) Test.
5.6.8.1. Perform this test only if the STB supports auto power
down as defined in section 2.2 of this appendix.
5.6.8.2. If the STB supports multi-streaming, operate the STB in
the multi-stream configuration (section 5.5.2 of this appendix) for
at least 5 minutes. If the STB does not support multi-streaming,
operate the STB in the on (watch TV) configuration (section 5.5.2 of
this appendix) for at least 5 minutes.
5.6.8.3. Momentarily (<1 second) press the ``Power'' button on
the remote only for any locally connected clients to place the
clients into sleep mode as defined in section 2.25.2. Some clients
may require a short period of time before they actually enter a
lower power consumption mode. If more than one display device is
locally connected to the STB, press the ``Power'' button for the
additional locally connected display devices and stream content to
one display device only.
5.6.8.4. Do not use (or move) the STB remote control after
section 5.6.8.3 of this appendix.
5.6.8.5. Allow the STB to operate until the STB enters sleep
mode or until 4 hours have elapsed, whichever occurs first.
5.6.8.6. If 4 hours have elapsed and the STB is not in sleep
mode, then the unit is not considered to support APD and
PSLEEP--APD shall be set equal to PWATCH.
5.6.8.7. Once the STB is in APD, begin power consumption
measurement in APD and record the average power consumed as
PSLEEP--APD over the time period as determined in section
5.6.2 of this appendix.
5.7. Off Mode Power Measurement.
5.7.1. Place the STB in off mode. If the STB cannot be placed
off mode as defined in section 2.25.3, then this test shall be
skipped.
5.7.2. Wait until the STB enters off mode.
5.7.3. Record the average power for 2 minutes as
POFF.
5.8. Sleep to On Mode Transition Time Measurement. The following
test is optional and should be performed to verify that the STB's
operation qualifies for sleep mode as described in section 2.25.2.
5.8.1. For the manual sleep test, place the STB in sleep mode
according to the steps specified in sections 5.6.7.2 through 5.6.7.5
of this appendix. For the APD test, place the STB in sleep mode
according to the steps
[[Page 5113]]
specified in sections 5.6.8.2 through 5.6.8.6 of this appendix.
5.8.2. Once the STB enters sleep mode, wait until the STB power
consumption reaches PSLEEP--MANUAL (+0.5 W, -0.0 W) for
the manual sleep test and PSLEEP--APD (+0.5 W, -0.0 W)
for the APD test.
5.8.3. After the STB power consumption reaches the desired value
as specified in section 5.8.2 of this appendix, remain in sleep mode
for at least 5 minutes.
5.8.4. Momentarily (<1 second) press the ``Power'' button on the
remote or front panel of the STB.
5.8.5. Begin the elapsed time measurement.
5.8.6. Stop elapsed time measurement when the STB enters on
mode. It shall be ensured that the STB has entered on mode when it
supports channel viewing on the connected display device or client.
5.8.7. The duration to transition from sleep mode to on mode
shall be recorded as TSLEEP--TO--ON, and this value shall
be used to compare against the sleep mode requirements described in
section 2.25.2.
6. Calculation of the Annual Energy Consumption of the Set-top
Box
6.1. The AEC of the STB shall be calculated using the rated
values of power consumption in the on, sleep, and off modes of
operation (see section 5.4.2 for calculation of rated power
consumption values).
6.2. Compute the AEC of the STB using the equation below. The
computed AEC value shall be rounded as follows:
6.2.1. If the computed AEC value is 100 kWh or less, the rated
value shall be rounded to the nearest tenth of a kWh.
6.2.2. If the computed AEC value is greater than 100 kWh, the
rated value shall be rounded to the nearest kWh.

Where:
AEC = annual energy consumption (in kWh per year),
PWATCH = the rated power consumption value (in W) in on
(watch TV) mode,
HWATCH = the number of hours assigned to on (watch TV)
mode according to Table 3 of this appendix,
PMULTI--STREAM = the rated power consumption (in W) in
the multi-stream test in on mode,
HMULTI--STREAM = the number of hours assigned to multi-
stream according to Table 3 of this appendix,
PSLEEP--MANUAL = the rated power consumption (in W) in
the manual sleep test in sleep mode,
HSLEEP--MANUAL = the number of hours assigned to manual
sleep according to Table 3 of this appendix,
PSLEEP--APD = the rated power consumption (in W) in the
APD test in sleep mode,
HSLEEP--APD = the number of hours assigned to APD
according to Table 3 of this appendix,
POFF = the rated power consumption (in W) in off mode,
and
HOFF = the number of hours assigned to off mode according
to Table 3 of this appendix.
