ENERGY STAR®
Qualifying Criteria for Audio/Video Equipment

Version 2.1

Download the PDF version of this document.

Products sold in Canada must meet all Canadian regulatory and safety requirements. Eligible equipment is to be qualified by the U.S. EPA.

In order to promote ENERGY STAR qualified Audio/Video Equipment in Canada, manufacturers are required to sign a Memorandum of Understanding (MOU) with the US Environmental Protection Agency (EPA). We encourage manufacturers, retailers and distributors to sign a Participant Administrative Arrangement with Natural Resources Canada to take advantage of promotional and communications opportunities provided by the program. More information

Please note that the U.S. EPA has made changes to the ENERGY STAR qualification process, in particular to include mandatory third party testing. You can find more information about those changes on the following web site: http//www.energystar.gov.

These criteria are the same as the program requirements published on the U.S. ENERGY STAR web site and are provided as information only. Administered by Natural Resources Canada's Office of Energy Efficiency, the ENERGY STAR program in Canada uses the term Participant to designate companies, organizations and stakeholders who promote the use of the ENERGY STAR mark on products or in promotional and marketing material and activities. This technical specification was modified to include this change. The use of the term Participant is similar in scope to that of Partner, which is used by the EPA ENERGY STAR Program.

Following is the Version 2.1 of the ENERGY STAR qualifying criteria for Audio/Video equipment. A product shall meet all of the identified criteria to earn the ENERGY STAR mark. Also, the EPA and Natural Resources Canada both reserve 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. A product must meet all of the identified criteria to earn the ENERGY STAR registered trademark.

1) Definitions

A. Product Types

  1. AV Product: A mains-connected product that offers audio amplification and/or optical disc drive functions. This definition does not include Dedicated Audio DSP Devices.
  2. Dedicated Audio DSP Device: A device that meets all of the following criteria:
    1. provides audio digital signal processing as its primary function;
    2. Provides support for RS-232, Ethernet, WiFi, IEEE-1394 FireWire or similar protocol for hard-wired or wireless remote control.
    3. does not provide audio amplification.

B. APD (Auto Power Down)

The capability to automatically switch a device from On mode to Sleep mode after a predetermined period of time (APD timing) has elapsed. APD timing begins when the following criteria have been met: (1) the device has ceased performance of all primary functions, or (2) the last user input has been received (e.g., remote control signal, volume adjustment). The intent of APD is that products will automatically power down into Sleep Mode when not in active use.

EXAMPLE: A DVD player is by definition performing a primary function during active video playback from the disc; and thus is not required to APD for the duration of active video playback. The same DVD player is expected to power down to Sleep Mode when video content playback concludes, such that the product does not indefinitely remain in On Mode while sitting in a disc menu screen.

C. Loss of Signal (LOS)

  1. For audio signals, LOS is defined as:
    1. Analog inputs: Less than 1 dB above the measured noise floor for 60 seconds.
    2. HDMI: Receive <Inactive Source> or <Standby> signal over the CEC channel, or [Power Status] of an upstream device goes to “Standby” or    “In Transition to Standby” over the CEC channel.
    3. Other Digital Inputs (e.g., Ethernet): No audio information in the data stream.
    4. Detectable cable disconnects.
  2. For video signals, LOS is defined as:
    1. Analog Inputs: Loss of either the horizontal or vertical sync signal.
    2. HDMI: Receive <Inactive Source> or <Standby> signal over the Consumer Electronics Control (CEC) channel, or [Power Status] of an upstream device goes to “Standby” or “In Transition to Standby” over the CEC channel; or detection of a disabled TMDS link, a TMDS clock line signal below 22.5 MHz for more than one second, or a TMDS link operating outside of the valid frequency range.
    3. DVI: Detection of a disabled TMDS link, a TMDS clock line signal below 22.5 MHz for more than one second, or a TMDS link operating outside of the valid frequency range.
    4. Other Digital Inputs (e.g., Ethernet): No video information in the data stream.
    5. Detectable cable disconnects.

D. Primary Function

Any discrete, dynamic device function that can be perceived by an end user, including the delivery or processing of audio/video content, and excluding the following:

  1. Continuous device functions (e.g. clocks, status displays, indicator lamps);
  2. Static device functions, such as:
    1.   No active audio or video processing or output;
    2.   Playback paused or stopped;
    3.   No optical disc media in disc drive; and,
    4.  Waiting in disc menu or other menu for user input.

E. Operational Modes

  1. On Mode
    Where the product is connected to a mains power source, has been activated and is capable of providing one or more primary functions. The common terms “active”, “in-use” and “normal operation” also describe this mode.
    1. Active State: A state within On mode in which a product is performing a primary function.
    2. Idle State: A state within On mode in which a product is not performing a primary function and no content is actively being delivered to the end-user.
  2. Sleep Mode
    The common term “standby” may also describe this mode, where the product is connected to a mains power source, is incapable of providing a primary function, and offers one or more of the following user oriented or protective functions which may persist for an indefinite time:
    1. to facilitate the activation of other modes (including activation of On mode) by remote switch (including remote control), internal sensor, timer;
    2. continuous function: information or status displays including clocks;
    3. continuous function: sensor-based functions.
      For purposes of this specification, Sleep Mode is defined as the time when the product is connected to a power source, produces neither sound nor picture, neither transmits nor receives program information and/or data (excluding data transmitted to change the unit’s condition from Sleep Mode to On Mode), and is waiting to be switched to On Mode by a direct or indirect signal from the consumer (e.g., with the remote control).


  3. Off Mode
    Where the product is connected to a mains power source, is not providing any On mode or Sleep mode functions, and cannot be switched into any other mode except by user actuation of a manual power switch. An indicator that only shows the user that the product is in the off position is included within the classification of an Off mode.

F. EPS (External Power Supply)

Also referred to as External Power Adapter. A component contained in a separate physical enclosure external to the AV product, designed to convert line voltage AC input from the mains to lower DC voltage(s) in order to provide power to the AV product.

6) Effective Date

6.1.1 Effective Date: The Version 2.1 ENERGY STAR Audio/Video specification shall take effect on the dates specified inTable 6. To qualify for ENERGY STAR, a product model shall meet the ENERGY STAR specification in effect on its date of manufacture. 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.

Table 6: Specification Effective Dates
  Tier 2     Tier 3  
 July 30, 2010   March 30, 2012 

6.1.2 Future Specification Revisions: EPA reserves the right to change this specification should technological and/or market changes affect its usefulness to consumers, industry, or the environment. In keeping with current policy, revisions to the specification are arrived at through stakeholder discussions. In the event of a specification revision, please note that the ENERGY STAR qualification is not automatically granted for the life of a product model.

TEST METHOD

1) Overview

The following test method shall be used for determining product compliance with requirements in the ENERGY STAR Eligibility Criteria for Audio/Video.

2) Applicability

ENERGY STAR test requirements are dependent upon the feature set of the product under evaluation. The following guidelines shall be used to determine the applicability of each section of this document:

  • Power mode tests (Section 7) shall be performed on every product;
  • Optical media player tests (Section 8) shall be performed on any product capable of playback or recording of audio and/or video stored on optical media (e.g., CD, SA-CD, DVD, Blu-ray Disc); and
  • Audio amplification tests (Section 9) shall be performed on any product that offers audio amplification.
  • Tests of the auto-power down (APD) function (Section 7.1) shall not be applicable to products subject to 3rd-party performance standards that prohibit APD.

Example: A typical Home Theater in a Box (HTIB) system with an integrated DVD player/recorder and audio amplifiers would be subject to the power mode tests in Section 7, several of the optical disc player tests in Section 6, and the full-spectrum audio amplifier tests in Section 8. In contrast, a stand-alone rack-mount audio amplifier would likely only be subject to the power mode tests in Section 5 and the full-spectrum audio amplifier tests in Section 9.

3) Definitions

Unless otherwise specified, all terms used in this document are consistent with the definitions contained in the ENERGY STAR Eligibility Criteria for Audio/Video.

4) Test Setup

The following tests shall be performed on any product capable of playback or recording of audio and/or video on optical disc media (e.g., CD, DVD, Blu-ray Disc). Tests shall be performed with both SD and HD video sources for devices capable of processing both SD and HD content.

8.1 Video Playback Test

  1. Insert / install the removable media and begin playback of IEC-62087 SD video content.
  2. Measure and record the average power over a 2 minute period.
  3. If the UUT is capable of playing HD content, repeat the test with IEC-62087 HD video content and record the average power over a 2 minute period.

8.2 Video Recording Test

  1. Insert / install the removable media and begin recording of IEC-62087 SD video content.
  2. Measure and record the average power over a 2 minute period.
  3. If the UUT is capable of recording HD content, repeat the test with IEC-62087 HD video content and record the average power over a 2 minute period.

8.3 Audio Playback Test

  1. Insert / install the optical disc media with a 1 kHz sine wave signal per Section 5.E) and begin playback.
  2. Measure and record the average power (PDISC) over a 2 minute period.

8.4 Audio Recording Test

  1. Insert / install the optical disc media and begin recording of a 1 kHz sine wave signal per Section 5.E).
  2. Measure and record the average power over a 2 minute period.

9) Test Procedures for Products with Audio Amplification

1) Connect the UUT to the output of the signal generator.

2) Connect an input of the UUT to a generated 1 kHz sine wave input signal per Section 5.E).

  1. For devices that accept only digital input signals, generate a representation of a 1 kHz sine wave.
  2. For devices without AV inputs, play back an audio disc with a 1 kHz sine wave signal per Section 5.E.
  3. If 1 kHz is outside the range of any bandwidth-limited channel in the UUT and the UUT has AV inputs, sweep the input signal frequency between the upper and lower -3 dB points of each channel. Record the input signal frequency when the UUT input power is at its maximum and use this frequency for the bandwidth-limited channel for the remainder of the test.

3) Monitor each channel, one at a time, with a distortion analyzer and power meter.

4) Set the volume of the UUT to 100% and adjust the amplitude of the input signal until the THD of any single channel is 1% or greater. For devices without AV inputs that are tested with an audio disc, adjust the volume until the THD of any single channel is 1% or greater.

5) Identify the channel or channels with the greatest output power. These shall be considered the reference channels and their output power shall be considered the maximum undistorted power (MUP)***.
*** If the UUT performs signal processing such that the amplifier output does not clip, maximum undistorted power shall be obtained by monitoring input signal amplitude and output power simultaneously to identify the point beyond which output power remains constant despite increases in input signal amplitude.

6) Measure and record the input power.

7) Reduce the input signal amplitude until the output power of the reference channel(s) is at 1/8 MUP. For devices without AV inputs that are tested with an audio disc, adjust the volume until the output power of the reference channel(s) is at 1/8 MUP

8) Measure and record the input power (PIN).

9) With the reference channel(s) at 1/8 MUP, measure and record the output power for all channels, averaged over a 2 minute period. Record the sum (POUT) of all output power measurements.
