Note: In response to questions received during the implementation of the Version 4.0 specification, EPA
has made several minor changes to the Version 4.2 specification for additional clarity. Clarifications and
additions are annotated throughout this document with note boxes. Version 4.2 and Version 5 have been
placed in separate documents to minimize confusion about specification effective dates. The changes
included in Version 4.2 will also be included in the Version 5 specification.
-------
34 c) a power state that meets the definition of Download Acquisition Mode.
35 7) Analog Television: A television product which has an NTSC, PAL, or SECAM tuner, and may
36 have analog video inputs (e.g., composite video, component video, S-video, RGB).
37 8) Digital Television: A television product which has at least one digital tuner or at least one digital
38 video input (e.g., HDMI). Products with an analog tuner and both analog and digital inputs are
39 considered digital products under this specification.
40 B) Native Vertical Resolution: The physical pixel count for the vertical axis of the television (e.g, a
41 television with a screen resolution of 1920 x 1080 (horizontal x vertical) would have a native vertical
42 resolution of 1080).
43 C) Electronic Program Guide (EPG): An interactive on-screen menu of TV program information
44 downloaded from an external source (e.g., program time, date, descriptions).
45 D) External Power Supply (EPS): Also referred to as External Power Adapter. A component contained in
46 a separate physical enclosure external to the television casing, designed to convert line voltage ac
47 input from the mains to lower dc voltage(s) in order to provide power to the television. An EPS
48 connects to the television via a removable or hard-wired male/female electrical connection, cable,
49 cord or other wiring.
50 E) Point of Deployment (POD) Module: A conditional access module for digital cable signal reception.
51 F) Luminance: The photometric measure of the luminous intensity per unit area of light traveling in a
52 given direction, expressed in units of candelas per square meter (cd/mA2).
53 G) Operational Modes:
54 1) On Mode: The power mode in which the product is connected to a mains power source, has been
55 activated, and is providing one or more of its principal functions. The common terms "active", "in-
56 use" and "normal operation" also describe this mode. The power in this mode is typically greater
57 than the power in Sleep Mode and in Download Acquisition Mode.
58 a) Power Overhang State: A power state within On Mode that is intended to facilitate a rapid
59 return to full functionality in the event a product is accidentally switched off. This feature is
60 present in some products that are designed to remain in a highly-functional "ready" state for a
61 limited amount of time after being switched off by the user.

ENERGY STAR Program Requirements for Televisions - Eligibility Criteria Page 2 of 10
Note: A definition for Power Overhang has been added to this document in response to stakeholder
questions about whether time spent in a high power operating state after the user has turned off the
television should be classified as part of Download Acquisition Mode. It is EPA's belief that these limited-
duration events have a negligible impact on total TV energy consumption, and should be allowed as an
extension of On Mode provided that power does not exceed On Mode limits and duration is limited to 3
minutes per occurrence. Requirements for Power Overhang are established in Section 3 of this
document.
2) Sleep Mode: The power mode, sometimes referred to as "Standby," in which the product is
connected to a mains power source, is not providing a principal function, and offers one or more
of the following user oriented or protective functions, which may persist for an indefinite time:
a) to facilitate the activation of other modes (including activation or deactivation of On Mode) by
remote switch (including remote control), internal sensor, timer.
-------
74 b) continuous function: information or status displays including clocks.
75 c) continuous function: sensor-based functions.
76 Sleep Mode is defined as the time when the product is connected to a power source, produces
77 neither sound nor picture, neither transmits nor receives program information and/or data
78 (excluding data transmitted to change the unit's condition from Sleep Mode to On Mode), and is
79 waiting to be switched to On Mode by a direct or indirect signal from the consumer (e.g., with the
80 remote control).
81 3) Off Mode: The power mode in which the product is connected to a mains power source, is not
82 providing any On Mode or Sleep Mode functions, and where the mode may persist for an
83 indefinite time. An indicator that only shows the user that the product is in the off position is
84 included within the classification of an Off Mode.
85 4) Download Acquisition Mode (DAM): The power mode in which the product is connected to a
86 mains power source, produces neither sound nor picture, and is actively downloading data. Data
87 downloads may include channel listing information for use by an electronic programming guide,
88 TV setup data, channel map updates, firmware updates, monitoring for emergency messaging /
89 communications or other network communications. The power in DAM is typically greater than
90 the power in Sleep Mode and is typically less than the power in On Mode.
91
92
93 H) Screen Area: The viewable screen area of the product, calculated by multiplying the viewable image
94 width by the viewable image height.
95 I) Product Family: A group of product models that are (1) made by the same manufacturer, (2) subject
96 to the same ENERGY STAR qualification criteria, and (3) of a common basic design. Product models
97 within a family differ from each other according to one or more characteristics or features that either
98 (1) have no impact on product performance with regard to ENERGY STAR qualification criteria, or (2)
99 are specified herein as acceptable variations within a product family. For Televisions, acceptable
100 variations within a product family include:
101 1) Color, and
102 2) Housing.
Note: EPA has adopted the definition of Download Acquisition Mode that was proposed in the CEA DAM
test procedure, with minor edits for consistency with ENERGY STAR specification language.
103

213 3.6 Download Acquisition Mode (DAM) Requirements
214 3.6.1 A product may automatically exit Sleep Mode and enter Download Acquisition Mode according to
215 a predefined schedule, in order to:
216 i. Download channel listing information for use by an electronic programming guide,
217 ii. Monitor for emergency messaging/communications, or
218 iii. Communicate via a network protocol.
219 3.6.2 Measured energy consumption for all DAM states (EDAm) shall be less than or equal to 0.08 kWh
220 per day (80 W-h per day).
ENERGY STAR Program Requirements for Televisions - Eligibility Criteria Page 6 of 10
EXAMPLE: The maximum On Mode power requirement for a TV with a width of 36.6 inches and a height
of 20.6 inches (screen area of 754 in2) would be: (0.120 * 754) +25= 115.4 watts, or 115 watts when
rounded to the nearest whole number.
3.3.3 Power Overhang:
Note: Stakeholders have advised EPA that many products on the market today make use of a "power
overhang" state of no more than 3 minutes duration to provide for a quick re-start if the television is
inadvertently turned off, and inquired as to whether this state should be classified as part of Download
Acquisition Mode.
EPA believes that an additional few minutes of power at the end of each On Mode power cycle will have
minimal impact on total energy consumption, and should not be considered part of DAM, but invites
additional comments related to this proposal.
The "minimal impact" rationale is as follows: Assume 3 power cycles per day x 3 minutes of On Mode
power = 9 additional minutes of On Mode. TEC assumes 5 hours (300 minutes) of On mode per day, so
the net effect of power overhang on TEC is 9/300 minutes, or 3%. For the most consumptive TV on the
current ENERGY STAR qualified products list (~ 400 kWh per year TEC) power overhang would result in
no more than an additional 12 kWh per year. For the average TV on the qualified products list, the net
impact on TEC would be no more than 5 kWh per year.
-------
221 3.7 Hospitality Television Requirements
222 3.7.1 Hospitality Television TEC (TECHosp), as calculated per Equation 2, shall be less than or equal to
223 the Maximum Hospitality Television TEC Requirement (TECHosp_max), as determined per Table 2.
224 3.7.2 For Hospitality Televisions that feature an always-on DAM, measured DAM power (PDAm) shall be
225 less than or equal to 1.0 W when tested per the Sleep Mode test procedures in the ENERGY
226 STAR Test Method for Televisions.
227
228
229
230
Note: EPA has proposed an exception to the qualifying products section to allow hospitality TVs with an
always-on DAM (but no traditional Sleep Mode, due to active networking) to qualify for ENERGY STAR,
provided that DAM power does not exceed the Sleep Mode power limit of 1.0 watt, and that the calculated
TEC does not exceed the TEC limit for Hospitality Televisions.
231 Equation 3: Calculation of TEC for Hospitality Televisions (TECHosp)

1. Energy Star TV Program Requirements - Procedure for DAM Testing
2. ENERGY STAR® Program Reguirements for Televisions Eligibility Criteria Versions 4.1 and 5.1
4 Definition of DAM mode
In Energy Star 4.1, the EPA defines the following:
Download Acquisition Mode (DAM): Where the product is connected to a mains
power source, is not producing a sound or a picture, and is actively
downloading data, to include but not limited to, channel listing information
according to a defined schedule for use by the electronic programming guide,
TV setup data, channel map updates, TV firmware updates, monitoring for
emergency messaging/communications and/or otherwise communicating
through a network protocol. The power use in this mode is typically greater than
the power requirement in Sleep and less than that in On Mode.
This test procedure introduces the following definitions:
Infrequent Download: Any DAM download that occurs no more than four times
per year and has a duration of less than six hours per instance (i.e., total of less
than 24 hours/year or 0.27%). Some examples of infrequent downloads are TV
firmware updates, TV setup data downloads, and the Rovi EPG Setup State.
Frequent Download: Any DAM download that does not meet the definition of an
Infrequent Download.
5 Qualifications to the DAM mode power usage
5.1 All frequent downloads must be included in the DAM mode power measurement.
Note: All DAM functionalities, both frequent and infrequent must be declared, but
those meeting the definition of infrequent can be excluded from the measurement
procedure. (This declaration is so that the EPA is made aware of, and thereby has
the option to evaluate the validity of, and test for the occurrences of, those
downloads defined as infrequent.)
5.1.1. Downloads that happen at a frequency of less than once per day, but do
not meet the definition of infrequent, must be averaged to come up with
an equivalent daily value for the DAM measurement.
5.2 There are also various triggers for the initiation of a DAM sequence. It may be a
daily trigger at a certain time of day (as an EPG download), or a TV power state
trigger (as a clock update that is performed each time the TV "turned off" before it
actually enters Sleep mode.) There are also other asynchronous external triggers
possible. Daily triggers need no further discussion, a TV power state trigger will be
-------
CEA Procedure for DAM Testing:
° 8 September 2010
For TVs
Page 3 of 8
assumed to happen five times per day. Asynchronous triggers must be estimated
in good faith, conservatively towards the high side of expected occurrence.
(Significant underestimation is clearly grounds for de-listing.)
6 DAM power measurement
To test for the power consumed in DAM, the Ideal or the Practical test method may
be used.
6.1 Ideal
6.1.1 To ideally measure the DAM mode power consumption, the TV should
be connected to power meter that measures the total energy consumed
(E_TOTAL) and a signal source that can provide a signal containing the
same type and amount or duration of data that the TV will acquire in its
actual application DAM use. The following procedure should be followed:
1. UUT shall be connected to a power meter that will measure the
total energy consumed over duration of the test.
2. A signal source shall be prepared that can provide a signal
containing the same type and amount or duration of data that the
TV will acquire over the course of an average 24 hour period. This
signal shall include representative segments from all Frequent
Downloads.
3. The energy consumption of the UUT shall be measured over a 24
hour period (E_TOTAL), during which the TV is turned on for 1 hour
then turned off for 1.5 hours 4 times then turned on for 1 hour and
off for 13 hours.
4. The following equation shall be used to derive the energy used in
DAM (E_DAM):
E_DAM = E_TOTAL - (P_ON * 5 Hours) - (P_SLEEP * 19 Hours)
Where:
E_TOTAL - Total energy used by the UUT over a 24 hour period
P_ON - On mode power consumption
P_SLEEP - Sleep mode power consumption
Time_DAM - Average time spent in DAM per day
6.2 Practical
6.2.1 For practical measurement of DAM mode power consumption, it can be
verified that the E_DAM can be calculated by simply multiplying the
-------
CEA Procedure for DAM Testing:
° 8 September 2010
For TVs
Page 4 of 8
instantaneous (P_DAM - P_SLEEP) by the time in DAM mode. The
following steps should be followed:
1. The TV shall be connected to a power meter and power source.
2. The TV shall be connected to an appropriate signal source for
communicating with the DAM function being tested.
3. The signal which causes the TV to activate the DAM function
should be applied.
4. Confirm that the TV has activated the DAM function and is
communicating with the DAM signal source as appropriate for the
DAM function being tested.
5. Record "P_DAM" (watts) power consumption in DAM using the
power meter.
6. Confirm "Time_DAM" (hours) time of DAM per day, and calculate
"E_DAM" by
the following equation:
E_DAM = (P_DAM - P_SLEEP) x Time_DAM
7. If there are different DAM functions for the same TV, repeat steps
1 through 6 for each DAM function. In this case, the total E_DAM
is calculated:
E_DAM = SUM((P_DAM - P_SLEEP) x Time_DAM)
Where:
P_SLEEP - Sleep mode power consumption
P_DAM - DAM power consumption for each DAM function
Time_DAM - Time spent in DAM for each DAM function
6.3 Verification
6.3.1 The average time per day spent in DAM mode is easily estimated and
easily verified by connecting the TV into its intended application and
monitoring the energy usage. It is self evident when the TV is in On
mode. When the TV is off and drawing less than 1W it must be in Sleep
mode, and when it is off and drawing more than 1W, it must be in DAM
mode. The verification should be repeated for several days in case a
less frequent download occurs on one day.
