标准范围

ISO/IEC 23002-7:20 22本文件规定了视频可用性信息（VUI）参数和补充增强信息（SEI）消息的语法和语义。本文档中定义的VUI参数和SEI消息被设计成以视频译码规范中指定的方式在经译码视频比特流内传送，或者由利用这种经译码视频比特流的系统的规范所确定的其它装置传送。本文档特别旨在与如由Rec指定的经译码视频位流一起使用。尽管它是以旨在足够通用的方式起草的，使得它也可以与其他类型的编码视频比特流一起使用。VUI参数和SEI消息可以帮助与解码、显示或其他目的相关的过程。然而，除非在参考说明书中另外指定，否则本文档中指定的VUI参数和SEI消息的解释和使用不是视频解码器或接收视频系统的所需功能。尽管为VUI参数和SEI消息指定了语义，但是解码器和接收视频系统可以简单地忽略VUI参数和SEI消息的内容，或者可以以与本文档中指定的内容有些不同的方式使用它们。

ISO/IEC 23002-7:2022 This document specifies the syntax and semantics of video usability information (VUI) parameters and supplemental enhancement information (SEI) messages. The VUI parameters and SEI messages defined in this document are designed to be conveyed within coded video bitstreams in a manner specified in a video coding specification or to be conveyed by other means determined by the specifications for systems that make use of such coded video bitstreams. This document is particularly intended for use with coded video bitstreams as specified by Rec. ITU？T H.266 | ISO/IEC 23090-3, although it is drafted in a manner intended to be sufficiently generic that it can also be used with other types of coded video bitstreams.
VUI parameters and SEI messages can assist in processes related to decoding, display or other purposes. However, unless otherwise specified in a referencing specification, the interpretation and use of the VUI parameters and SEI messages specified in this document is not a required functionality of a video decoder or receiving video system. Although semantics are specified for the VUI parameters and SEI messages, decoders and receiving video systems can simply ignore the content of the VUI parameters and SEI messages or can use them in a manner that somewhat differs from what is specified in this document.
