ISO/IEC TR 23008-14:2018本文件提供了高动态范围（HDR）和宽色域（WCG）视频内容处理指南。本文件旨在为适用于压缩HDR/WCG视频的AVC或HEVC视频编码系统的操作提供一套可供公众参考的推荐指南，以供消费者分销应用。本文档描述了将4:4:4 RGB线性光表示视频信号转换为非线性光表示视频信号的处理步骤-恒定亮度（NCL）Y′CbCr视频信号，使用SMPTE ST 2084和建议ITU-R BT.2100中定义的感知量化器（PQ）传递函数。尽管本文件的重点主要是4:2:0 Y′CbCr 10位表示，但这些指南也适用于具有更高位深度或其他颜色格式的其他表示，例如4:4:4 Y′CbCr 12位视频。此外，本文件还提供了一些使用AVC或HEVC视频编码标准压缩这些信号的高级建议。还包括用于将这些NCL Y′CbCr信号转换回线性光、4:4:4 RGB表示的解码后处理步骤的描述。

ISO/IEC TR 23008-14:2018 This document provides guidance on the processing of high dynamic range (HDR) and wide colour gamut (WCG) video content. The purpose of this document is to provide a set of publicly referenceable recommended guidelines for the operation of AVC or HEVC video coding systems adapted for compressing HDR/WCG video for consumer distribution applications. This document includes a description of processing steps for converting from 4:4:4 RGB linear light representation video signals into non-constant luminance (NCL) Y′CbCr video signals that use the perceptual quantizer (PQ) transfer function defined in SMPTE ST 2084 and Rec. ITU-R BT.2100. Although the focus of this document is primarily on 4:2:0 Y′CbCr 10 bit representations, these guidelines are also applicable to other representations with higher bit depth or other colour formats, such as 4:4:4 Y′CbCr 12 bit video. In addition, this document provides some high-level recommendations for compressing these signals using either the AVC or HEVC video coding standards. A description of post-decoding processing steps is also included for converting these NCL Y′CbCr signals back to a linear light, 4:4:4 RGB representation.
