IEC TR 63449:2023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。它将具有动态元数据的内容与不具有动态元数据的相同内容的功耗进行比较。诸如HDR10的非动态“静态元数据”HDR技术和诸如HLG的非元数据HDR先前在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，分析了现有的HDR电视功率测量方法以及对这些功率测量标准的任何变化的考虑因素。 而本文档研究了包含杜比视界的内容的结果？和HDR10+动态元数据，这两种技术的任何比较都超出了本文档的范围。

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.
