Introduction

As important consumer products, audio and video products are widely used in consumers' homes: The power consumption of audio and video and related equipment has become a major concern for consumers:

The development of this document provides a practical evaluation method for the power consumption evaluation of audio and video and related equipment, which will help strengthen the consumer product field:

It has played a positive role in building the domain standard system and promoting the healthy development of the industry:

GB/T 44021 "Measurement of power consumption of audio, video and related equipment" is planned to consist of 6 parts:

--- Part 1: General: The purpose is to specify general requirements for power consumption measurements of audio, video and related equipment:

--- Part 2: Test signals and media: The purpose is to give the test signals for audio, video and related equipment such as televisions and computer monitors:

Signals and media used when measuring power consumption:

--- Part 3: Television sets: The purpose is to specify the power consumption measurement and related characteristics of television sets:

--- Part 4: Video recording equipment: The purpose is to describe the power consumption measurement method of video recording equipment with removable media and give the power consumption Measurement related various operation modes:

--- Part 5: Set-top Box (STB): The purpose is to describe the power consumption measurement method of the set-top box and give various Operation mode:

--- Part 6: Audio equipment: The purpose is to describe the power consumption measurement method of audio equipment:

Power consumption measurement of audio, video and related equipment Part 1: General

1 Scope

This document specifies general requirements for the measurement of power consumption in audio, video and related equipment: Requirements for specific types of equipment are specified in other documents:

may supersede the requirements given in this document:

Additionally, this document defines various operating modes that are relevant for power consumption measurements:

The other documents apply only to devices powered by an external power source: Devices with a non-removable main battery are not included in this document:

Any number of auxiliary batteries may be included:

This document provides an example of a verification process for using indicated values to access the compatibility of a specific model of equipment:

The measurement conditions in this document represent normal usage of the device and may differ from usage under specific conditions, such as those specified in safety standards:

The usage is different under the specified conditions:
