标准摘要
[中文适用范围]： 本文件研究了具有"动态元数据"的高动态范围（HDR）技术对电视亮度和功耗的影响。它将带有动态元数据的内容与不带动态元数据的相同内容的功耗进行了比较。非动态"静态元数据"HDR技术（如HDR10）和非元数据HDR（如HLG）已在IEC TR 63274:2021中进行了研究。 本文件还回顾了当前的HDR电视市场，并分析了现有的HDR电视功率测量方法以及对那些功率测量标准进行任何更改的考虑。 虽然本文件研究了包括Dolby Vision®和HDR10+动态元数据在内的内容的结果，但比较这两种技术不在本文件的范围内。 [外文原描述]： IEC TR 63449:2023 presents a study of the impact of high dynamic range (HDR) technologies with "dynamic metadata" on TV luminance and power consumption. It compares the power consumption of content with dynamic metadata to the same content without dynamic metadata. Non-dynamic "static metadata" HDR technologies such as HDR10 and non-metadata HDR such as HLG, were previously studied in IEC TR 63274:2021. This document also reviews the current HDR TV market and analyses existing HDR TV power measurement methods and considerations for any changes to those power measurement standards. While this document studies the results of content that include Dolby Vision® and HDR10+ dynamic metadata, any comparison of these two technologies is outside of the scope of this document.
