信息技术 沉浸式媒体的编码表示 第3部分：多功能视频编码

[中文适用范围]： 本文档规定了一种称为通用视频编码 (VVC) 的视频编码技术，该技术包括一种视频编码技术，其压缩能力大大超出此类标准的前几代，并且具有足够的通用性，可在广泛的应用中有效使用。仅指定了语法格式、语义和相关的解码过程要求，而其他事项（例如预处理、编码过程、系统信令和多路复用、数据丢失恢复、后处理和视频显示）被认为超出了本文档的范围。此外，解码器内执行的内部处理步骤也被认为超出了本文档的范围；只需要外部可观察的输出行为即可符合本文档的规范。本文档旨在通用，因为它适用于广泛的应用、比特率、分辨率、质量和服务。应用包括但不限于数字存储媒体、电视广播和实时通信的视频编码。在创建本文档的过程中，我们考虑了典型应用的各种要求，开发了必要的算法元素，并将它们集成到单个语法中。因此，本文件旨在促进不同应用程序之间的视频数据交换。 [外文原描述]： This document specifies a video coding technology known as versatile video coding (VVC), comprising a video coding technology with a compression capability that is substantially beyond that of the prior generations of such standards and with sufficient versatility for effective use in a broad range of applications. Only the syntax format, semantics, and associated decoding process requirements are specified, while other matters such as pre-processing, the encoding process, system signalling and multiplexing, data loss recovery, post-processing, and video display are considered to be outside the scope of this document. Additionally, the internal processing steps performed within a decoder are also considered to be outside the scope of this document; only the externally observable output behaviour is required to conform to the specifications of this document. This document is designed to be generic in the sense that it serves a wide range of applications, bit rates, resolutions, qualities and services. Applications include, but are not limited to, video coding for digital storage media, television broadcasting and real-time communication. In the course of creating This document, various requirements from typical applications have been considered, necessary algorithmic elements have been developed, and these have been integrated into a single syntax. Hence, this document is designed to facilitate video data interchange among different applications.
