ENERGY STAR Program Requirements for Set-top Boxes - Eligibility Criteria (Revised Feb-2011) 3 ------- DP.TEC: Total Energy Consumption. TEC is an assessment tool used in this specification that provides flexibility to approach the issue of energy efficiency while retaining a comparable metric to assess performance. In this specification, efficiency criteria are noted in terms of calculated energy use over a year for a typical user (kWh/yr) rather than power (watts) for On and Sleep states. EE. UUT: Unit Under Test (UUT) refers to the product being tested. Source: CSA C380-08 modified. 2) Qualifying Products: In order to qualify as ENERGY STAR under Tier 1 of this specification, STBs must meet the definition for these products in Section 1 and meet the technical requirements in Section 3. The following devices that fall within the definition of a STB, or provide functions similar to STBs, do not qualify under this Tier 1 specification. EPA envisions that the below excluded products list will likely be modified for the Tier 2 phase of this specification: Tier 1 Excluded Products: • Game Consoles (See definition above) • DTAs (See definition above) • IP STBs sold or provided outside of a dedicated service or service contract • Products that meet the definitions in the ENERGY STAR® Program Requirements for Consumer Audio and DVD Products 3) Energy Efficiency and Power Management Criteria: Only those products addressed by the Qualifying Products definition in Section 2 that meet the following criteria may qualify for ENERGY STAR. A) Calculated TEC Criteria The criterion for ENERGY STAR qualified STBs is a calculated TEC (in annual kWh). The criterion (herein called an "allowance") is an allowance for Base Functionality, plus allowances for specific, additional functionalities present across a duty cycle. This duty cycle is further explained in Section 4. B) Base Functionality Allowance The Base Function shall be established as detailed below. a. If the STB meets the definition of Cable STB above, regardless of whether the cable reception is considered the "principal function" by the manufacturer or Service Provider, and/or the STB is capable of receiving cable service after installation of a CableCARD™ or other type of conditional access (CA) system, the Base Functionality is CABLE. b. If the STB Base Function is not CABLE, and the STB meets the definition of Satellite STB above, regardless of whether the satellite reception is considered the "principal function" by the manufacturer or Service Provider, the Base Functionality is SATELLITE. c. If the STB Base Function is not CABLE or SATELLITE, and the STB meets the definition of IP STB above, regardless of whether the IP reception is considered the "principal function" by the manufacturer or Service Provider, the Base Functionality is IP. d. If the STB Base Function is not CABLE, SATELLITE, or IP, and the STB meets the definition of Terrestrial STB above, regardless of whether the terrestrial reception is considered the "principal function" by the manufacturer or Service Provider, the Base Functionality is TERRESTRIAL. ENERGY STAR Program Requirements for Set-top Boxes - Eligibility Criteria (Revised Feb-2011) 4 ------- e. If the STB Base Function is not CABLE, SATELLITE, IP or TERRESTRIAL, and the STB otherwise meets the definition of Thin-Client/Remote, the Base Function is THIN- CLIENT/REMOTE.

(Note there may not be any additional functions in devices such as standard cable or satellite STBs.) This sum is the calculated annual kWh limit, or TEC value. This sum equals the maximum amount of energy the box can use in a given year as calculated following the ENERGY STAR test procedure. Annual Energy Allowance (kWh/year) = Allowance Base Functionality Allowance + Additional Functionalities 1 Tier 2 limits have been provided throughout this specification as preliminary targets that will be reevaluated by EPA and finalized at least nine months prior to the Tier 2 effective date. 2 Additional Tuners adder applies only once, regardless of the number of tuners. 3 Additional Tuners adder applies only once, regardless of the number of tuners. 4 The Adv. Video Processing adder only applies once per box and can not be applied multiple times. 5 Credit for High Definition applies to all STBs except those with Base Functionality of TERRESTRIAL. 6 The Multi-room adder applies only once, regardless of the number of rooms served by the device. 7 The cable card adder can be applied on a per cable card basis. 8 OEMs must test with DOCSIS enabled if DOCSIS is present. Service providers can test with it and take the allowance only if they use it. ENERGY STAR Program Requirements for Set-top Boxes - Eligibility Criteria (Revised Feb-2011) 5 ------- Examples: (A) Under Tier 1, the energy allowance for a high-definition, Cable STB with DVR to qualify for ENERGY STAR would be 165 kWh/y (70 kWh/y for the base function, 35 kWh/y for the high definition and 60 kWh/y for the DVR). (B) Under Tier 2, the energy allowance for the same product would drop to 94 kWh/y. E) STBs Using an External Power Supply To qualify, the external power supply (EPS) used with STBs manufactured after the effective date of this specification must be ENERGY STAR qualified or meet the no-load and active mode efficiency levels provided in the ENERGY STAR Program Requirements for Single Voltage Ac-Ac and Ac-Dc External Power Supplies, Version 2.0. The ENERGY STAR specification and qualified product list can be found at: www.eneravstar.gov/powersupplies. STBs manufactured prior to the effective date of this specification that can meet the energy-efficiency performance requirements in the ENERGY STAR STB specification do not need to use an ENERGY STAR qualified (or equivalent) EPS. F) Multi-Room STBs When using the Multi-Room Additional Functionalities energy allowance to establish the criteria for a STB, the following procedure must be followed. This allowance may only be used for STBs that can provide independent content to more than one display device, e.g., TV, PC, portable media player, etc. For the purposes of this specification, TV can be any device capable of streaming realtime video from the UUT to an independent display while keeping better than 480i resolution. Specific requirements for testing Multi-Room STBs are included below. • First, test the multi-room STB and compare the results to the specification criteria assuming the STB will deliver content to only one TV, i.e., do not include the Multi-Room allowance. If the STB passes, then it qualifies as an ENERGY STAR qualified STB under any installation configuration, i.e., it can be used for one or more TVs. • If the STB does not pass the single TV STB test, then determine if it qualifies as a Multi-Room STB. o Retest with a second TV running the same test simultaneously with the first, o Add the Multi-Room additional annual energy allowance listed in Table 2 to the criteria established for the STB. Compare the test results to the Multi-Room criteria to see if the STB qualifies for ENERGY STAR. For units that can support a second TV without the need for a thin client, and do this via widely used N/ATSC (unencrypted) via RF, the manufacturer can add in half of the relevant thin client adder, o If the STB qualifies as a Multi-Room STB, manufacturer must clearly indicate in product literature that product only qualifies for ENERGY STAR when providing content to more than one TV. G) Speculative Recording Devices that provide for speculative recording must have a user-accessible menu option allowing the user to disable this feature at will. Manufacturers must also include instructions for disabling speculative recording in product materials. ENERGY STAR Program Requirements for Set-top Boxes - Eligibility Criteria (Revised Feb-2011) 6 ------- 4) Testing Products for ENERGY STAR: A) Product Testing Set-up. Procedures, and Documentation The test results produced by the ENERGY STAR test procedure shall be used as the primary basis for determining ENERGY STAR qualification. Manufacturers are required to perform tests and self-certify those models that meet the ENERGY STAR requirements. This is confirmed by testing for ENERGY STAR qualification while the product is connected to the system, either on a live system or at a representative system in a laboratory. When qualifying and reporting STBs for ENERGY STAR, the following procedure shall be used to determine that an appropriate representative sample size has been tested. 1) Select on a random basis five units of the STB model to be tested. If the units have been refurbished, all units must have undergone the same refurbishment or reconfiguration, and must have received the same new hardware components or new or updated software. 2) Test three units drawn at random from the pool of five units following the test procedure specified in the ENERGY STAR Program Requirements for Set-top Boxes - Version 2.0. a) If all three units meet the applicable ENERGY STAR criteria, and are not within 10% of the allowance in the specification, then the STB model meets ENERGY STAR requirements and no more testing is needed. b) If all three units meet the applicable ENERGY STAR criteria, but any are within 10% of the allowance in the specification, go to step 3. c) If any of the three units do not meet the ENERGY STAR criteria, then the STB model does not meet ENERGY STAR requirements and cannot be referred to as ENERGY STAR qualified. 3) Test the additional two units in the pool. If both units meet the applicable ENERGY STAR criteria, then the STB model meets ENERGY STAR requirements and no more testing is needed. If either of the two units does not meet the applicable ENERGY STAR criteria, then the STB model does not meet ENERGY STAR requirements and cannot be referred to as ENERGY STAR qualified. B) TEC Assessment In this specification, the power consumed in the On and Sleep states will be multiplied by the number of hours a defined typical device spends in On and Sleep. The result will be a single energy value representing the energy usage of the device over the course of an entire year. To determine if a STB meets the ENERGY STAR specification criteria (Annual Energy Allowance), the TEC of the STB shall be calculated as follows. If the TEC assessed for the product is less than the Annual Energy Allowance calculated from Section 3D, the product meets the criteria and has earned the ENERGY STAR. C) Equation 1: Base Assessment Applies To All Products Calculate the Base energy consumption by multiplying the measured power consumption as specified in this test procedure by the hours per day values in the equations below. If the UUT (Unit Under Test) does not include the capability for auto power down, then use the first equation (a). If the product does include auto power down capability, and it meets the requirements in section (F) below then use the second equation (b). Ptv, Psieep and PAut0 pd are power levels in watts as measured according to the ENERGY STAR test procedure. ENERGY STAR Program Requirements for Set-top Boxes - Eligibility Criteria (Revised Feb-2011) 7 ------- a) Annual energy (kWh/yr) for a product with no auto power down kWhs^ = 0-365 x(l4x Ptv +10 x Pslee^) b) Annual energy (kWh/yr) for a product with auto power down capability kWhn-Asc = 0-365x((7x I'rv)+ (j 0 /Psleep(7xPAut0PD Examples: (C) The UUT (HD DVR cable STB, Tier 1) does not have auto power down capability, and the measurements during the test procedure are as follows: PTV = 24.0 watts and PsieeP= 18.0 watts. The annual energy consumption is then: kWhBase= 0.365 *(14 *24.0 + 10* 18.0) = 188.3 kWh/yr (D) The UUT (HD DVR cable STB, Tier 1) does have auto power down capability, and the measurements during the test procedure are similar to example A: PTV = 24.0 watts, PSieep = 18.0 watts and PAutoPD = 18 watts. The annual energy consumption is then: kWhBase= 0.365 *(7 *24.0 + 10* 18.0 + 7* 18.0) = 173 kWh/yr D) Equation 2: Playback and Record Assessment The table and equation below illustrate how to calculate from the values measured in the test procedure the annual energy consumption for the added functionalities such as playback and record. These apply only to products with a DVR, Removable Media Playback, or Removable Media Playback with Record capabilities. Sum the results for all functionalities applicable to the UUT. Ptv, Ppiayback and PReCord are power levels in watts as measured according to the ENERGY STAR test procedure. 2 kWH Play/Record =0-365 X^(Pmodg - PTp ) X Hmod e Table 3: Duty Cycle Mode DVR (Hours/Day) Removable Media Playback (Hours/Day) Removable Media Playback w / Record capability (Hours/Day) Hours On-Playback (H Playback) 2 2 2 Hours On-Record (H Record) 3 0 1 Example: (E) Consider the Cable STB with DVR product in example (C) above with a PTV of 24.0 watts. Following the test procedure, it is found that Ppiayback is 30.0 watts and PreCord is 32.0 watts. kWhplay/Record = 0.365 * ((30.0 - 24.0) * 2 + (32.0 - 24.0) * 3) = 13.1 kWh/yr ENERGY STAR Program Requirements for Set-top Boxes - Eligibility Criteria (Revised Feb-2011) 8 ------- E) Total Energy Consumption If the STB includes a DVR, Removable Media Playback, or Removable Media Playback with Record capability, add the results of Equation 1 and Equation 2. If the STB does not include DVR, Removable Media Playback, or Removable Media Playback w/ Record capability, the TEC is equal to Equation 1. Example: (F) In the case of a HD STB with a DVR as used above, the TEC would be the sum of Equation 1 and Equation 2 (188.3 + 13.1) for a total of 201.4 kWh/yr for this STB. F) Auto Power Down Auto power down (APD) capability is not a requirement under this specification. However, credit for anticipated energy savings for STBs that include APD capability is provided in Section C: Equation 1: Base Assessment - if the requirements in this subsection (F) are met. When claiming the presence of APD functionality for purposes of using equation 1b (Section C: Equation 1: Base Assessment) and calculating the TEC, the following requirements must be met: The STB must be shipped from the manufacturer with the APD setting engaging at four hours or less of inactivity. It is acceptable for the current program to complete before switching to the Sleep state. The energy-related settings shipped as the default by the manufacturer shall persist unless the user chooses at a later date to manually: a) disable the APD, or b) adjust the default time period from four hours or less to some other value. Partner may choose to not allow user the option of changing the power down settings. The STB may exit an automatically-initiated Sleep state in order to download content and scan for program and system information, scheduling information, or any other maintenance activity. After activity is complete, STB must return to Sleep state within no more than 15 minutes. If this occurs, the STB may exit the Sleep state for no longer than an average of two hours in a twenty-four (24) hour period. This requirement of two hours per day does not include activities that an end user schedules (e.g. video recording of a daily show). Video downloads that are not user-requested (e.g. "speculative recording", or "push") are to be counted against the two hour average per day requirement. G) Submittal of Qualified Product Data to EPA Partners are required to report data on those models that meet the ENERGY STAR guidelines to EPA. The test results must be reported to EPA using the Set-top Box Version 2.0 Qualifying Product Information (QPI) Form. 5) User Interface: Although not mandatory, manufacturers are strongly recommended to design products in accordance with the Power Control User Interface Standard — IEEE 1621 (formally known as "Standard for User Interface Elements in Power Control of Electronic Devices Employed in Office/Consumer Environments"). Compliance with IEEE 1621 will make power controls more consistent and intuitive across all electronic devices. For more information on the standard, see http://eetd.LBL.gov/Controls. 6) Effective Date: The ENERGY STAR specification for STBs (Version 2.0) Tier 1 is effective January 1, 2009. Tier 2 will become effective on January 1, 2011. Any previously executed agreement on the subject of ENERGY STAR qualified set-top boxes terminated effective February 2, 2005. 1. Qualifying and Marking products under the Tier 1 Version 2.0 specification: All products, including models originally qualified under Version 1.0, with a date of manufacture on or after January 1, 2009, must meet the new (Version 2.0) requirements in order to qualify for ENERGY STAR. The date of manufacture is specific to each unit and is the date (e.g., month and year) on which a unit is considered to be completely assembled. ENERGY STAR Program Requirements for Set-top Boxes - Eligibility Criteria (Revised Feb-2011) 9 ------- 2-.—Qualifying and Marking products under the Tier 2 Version 2.0 specification: All products, including models originally qualified under Tier 1 Version 2.0, with a date of manufacture on or after January 1, 2011, must meet the Tier 2 requirements in order to qualify for ENERGY STAR. 3. Elimination of Grandfathering: EPA will not allow grandfathering under this Version 2.0 ENERGY STAR specification. ENERGY STAR qualification under previous Versions is not automatically granted for the life of the product model. Therefore, any product sold, marketed, or identified by the manufacturing partner as ENERGY STAR must meet the current specification in effect at the time of manufacture of the product. 7) Future Specification Revisions: EPA reserves the right to revise the specification should technological and/or market changes affect its usefulness to consumers or industry or its impact on the environment. In particular, EPA will finalize Tier 2 elements identified as TBD and reevaluate the appropriateness of other Tier 2 criteria at least nine months prior to the Tier 2 effective date. In keeping with current policy, revisions to the specification will be discussed with stakeholders. In the event of a specification revision, please note that ENERGY STAR qualification is not automatically granted for the life of a product model. To qualify as ENERGY STAR, a product model must meet the ENERGY STAR specification in effect on the model's date of manufacture ENERGY STAR Program Requirements for Set-top Boxes - Eligibility Criteria (Revised Feb-2011) 10 ------- ENERGY STAR for Set-top Boxes Test Procedure I Nf.MGY S1AK pahim:r This document is being proposed for addition to C380-08: Test procedure for the measurement of energy consumption of set-top boxes (STBs) for purposes of testing and qualifying products under: (1) ENERGY STAR Program Requirements for Set-Top Boxes - Version 2.0; and (2) ENERGY STAR Program Requirements for Cable, Satellite, and Telecom Service Providers - Version 1.0. All requirements for qualifying to the ENERGY STAR requirements are contained herein. 5 Duty Cycle Workload Testing Procedure 5.1 Background The purpose of this section is to provide a workload-based test procedure centered on the actions of the user and the practical output of STBs when placed in situ. These are meant to mimic general actions and general conditions of STBs when used by the average user and are not meant to represent all conditions for all possible box functions and user scenarios. 5.1.1. Definitions For purposes of this section (5 Duty Cycle Workload Testing Procedure), the definitions contained in (1) ENERGY STAR Program Requirements for Set-Top Boxes - Version 2.0, and (2) ENERGY STAR Program Requirements for Cable, Satellite, and Telecom Service Providers - Version 1.0 supercede those in section "3 Definitions and abbreviations" of C380-08 Test procedure for the measurement of energy consumption of set-top boxes (STBs). 1 ------- 5.2 Preparation 5.2.1 Measurement of Energy Consumption For purposes of this workload-based test procedure, the following portions of section 4 of C380- 08 as amended, shall be followed. 4.1 General Average power shall be measured from the AC power source to the equipment being tested. 4.2 Test conditions 4.2.1 General Unless otherwise specified, measurements shall be made under test conditions and with equipment specified below. 4.2.3 Test room The tests shall be carried out in a room that has an air speed close to the UUT of <0.5 m/s, and the ambient temperature shall be maintained at 23°C ± 5°C throughout the test. The UUT shall be tested on a thermally non-conductive surface 4.2.4 Test voltage An AC power source shall be used to provide input voltage and frequency of 115± 1% at 60 Hz to the UUT. The Total Harmonic Distortion (THD) of the supply voltage when supplying the UUT in the specified mode shall not exceed 2%, up to and including the 13th harmonic. The peak value of the test voltage shall be within 1.34 and 1.49 times its RMS value. 4.2.5 Test leads All leads used in the test set-up shall be of a sufficient gauge and length in order to avoid the introduction of errors in the testing process. Note: For further guidance, see Table B.2, "Commonly used values for wire gages and related voltage drops" in IEEE 1515. 4.4 Test equipment 4.4.1 General The following should be considered when selecting test equipment: (a) an oscilloscope with a current probe, to monitor AC line current waveform, amplitude, and frequency; (b) a true rms volt meter, to verify voltage at the input of the unit being tested (optional if AC source output is sufficiently accurate); and (c) a frequency counter, to verify frequency at the input of the unit being tested (optional if AC source output is sufficiently accurate). 2 ------- 4.4.2 Calibration Test instruments shall be calibrated annually to traceable national standards to ensure limits of error in measurement no greater than ± 0.5% of the measured value over the required bandwidth of the output. 4.4.3 True power watt meter 4.4.3.1 Crest Factor A true power watt meter, with accuracy and, resolution in accordance with 4.4.2, and 4.4.3.4 and sufficient bandwidth , and crest factor rating appropriate for the waveforms being measured, shall be used. The selected watt meter's crest factor rating shall be capable of reading the available current waveform without clipping the waveform. The peak of the current waveform measured during SLEEP and ON states for the UUT shall determine the crest factor rating requirement and the appropriate 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% greater than the peak current to prevent any measurement error. 4.4.3.2 Bandwidth The current and voltage signal shall be analyzed to determine the highest frequency component (harmonic) with a magnitude greater than 1% of the fundamental frequency under the test conditions. This shall determine the minimum bandwidth of the test instruments. The meter shall be capable of sampling at a minimum of one second intervals. 4.4.3.3 Frequency response A watt meter with a frequency response of at least 9 kHz shall be used, which accounts for harmonics up to the 50th. Note: Electronic equipment can cause harmonic waveforms that lead to inaccuracies in power measurements. 4.4.3.4 Resolution The power measurement instrument shall have a resolution of: • 0.01 W or better for power measurements of 10 W or less; • 0.1 W or better for power measurements of greater than 10 W up to 100 l/l/; and • 1 W or better for power measurements of greater than 100 l/l/. 3 ------- 5.2.2 General The box and test conditions should be prepared according to section 5.2.1 above. a. Begin the test by connecting all relevant A/V connectors. b. Next plug the box into the power source and let the unit sit for 15 minutes as the unit initializes and comes to a ready state. c. Do not attach external devices that are not required for operation and/or that will not be used with the device under normal operation. d. For signal source input, ensure that the box is connected to the input source and the input source conforms to the source signal requirements below e. Connect the UUT to a display device (e.g. TV) via the applicable interface(s) supported by the UUT (e.g. composite video output). f. If the UUT supports conditional access system control, then provision the UUT as applicable for the UUT type (e.g. Cable, Satellite, Telcocom, or IP STB). g. Functions to disable: WiFi (unless WiFi is the primary network connection), VOIP and data services (those exposed to the user for external use such as broadband services) h. Source Signals a. All Cable STBs interacting with Conditional Access (CA)system data via DOCSIS Set-top Gateway (DSG) orSCTE-55 as applicable for the product b. All Telcocom QAM/IP STBs interacting with CA system data via SCTE-55 and/or via an applicable LAN technology (e.g. Multimedia Over Coax - MoCA). c. All IP STBs interacting with CA system data via applicable LAN technology (e.g. IEEE-802.3, Multimedia Over Coax - MoCA) d. STBs with POD/CableCard - encrypted content is decrypted by POD/CableCard e. All Satellite STBs - interacting with CA system via LNB and POTS modem f. All Terrestrial STBs - ATSC signal from a live source. 5.2.3 Duty Cycle Specific Test Conditions a. Remote: In all cases, user input should be accomplished with the remote in cases where the unit ships with one, otherwise the unit's face controls should be utilized. In cases where the functionality needed is not on the remote, then for that particular function the face mounted controls should be utilized. b. Reset the meter after each test. c. When tuning to a broadcast video source, this is defined as one tuner acquiring an encrypted digital video service, where the video service is rendered on all analog audio/video output (e.g. RF modulated, S-Video, composite and component) and on all SPDIF audio outputs (if equipped). d. If the UUT uses Smart card or POD technology for conditional access system control, then insert the applicable card into the UUT prior to applying power. i. Reference Channels: a. [A] Standard Definition network TV (minimum 480i) b. [B] Live/Recorded Sporting channel. When the box is HD-capable, this channel should be the HD version, (minimum 480i in SD, 720p in HD) c. [C] Standard Definition news channel, i.e., 24 hour news channel, (minimum 480i) 5.2.4 Other Specific Test Conditions The following additional test conditions apply. a. Satellite Low Noise Block (LNB): incremental power required to operate the LNB(s), if drawn from the STB, may be subtracted from the power measurements. It is preferable that all LNB power drawn be supplied separately. Otherwise, the amount subtracted must be clearly noted on the Qualified Product Information (QPI) form. b. Functions to Disable: WiFi (unless WiFi is the primary network connection), VOIP and Data services (those exposed to the user for external use such as broadband services) 4 ------- 5.3 Active Tests 5.3.1 Live TV (PTv) a.
