音频、视频和相关设备.功耗的测定.第3部分:电视机

[中文适用范围]： 本部分IEC 62087规定了电视机功率消耗及相关特性的测定方法。电视机包括但不限于采用LCD、OLED或投影技术的设备。详细定义了电视机的工作模式和功能。本文件仅适用于可连接外部电源的电视机，不包括带有不可拆卸主电池的电视机（可包含任意数量的辅助电池）。测量条件代表设备正常使用情况，可能与安全标准等特定条件不同。 [外文原描述]： IEC 62087-3:2023 specifies the determination of the power consumption and related characteristics of television sets. Television sets include, but are not limited to, those with LCD, OLED, or projection technologies. The operating modes and functions, as they specifically apply to television sets, are defined in detail in this part of IEC 62087. This document is limited to television sets that can be connected to an external power source. Television sets that include a non-removable, main battery are not covered by this document. Television sets can include any number of auxiliary batteries. The measuring conditions in this document represent the normal use of the equipment and can differ from specific conditions, for example as specified in safety standards. IEC 62087-3:2023 cancels and replaces the first edition published in 2015. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) it introduces measuring procedures for the determination of power consumption in the On mode while viewing static metadata HDR video content; b) all tests for On mode power determination are performed with MDD disabled; c) only progressive video signals are used for testing; d) a dimmable LED reflector lamp is used as a light source for illuminating the ABC sensor to achieve specific illuminance levels; e) a dynamic box and outline video signal is used for determining the ratio of peak luminance.
