标准范围

本文档规定了一种被称为通用视频编码(VVC)的视频编码技术，其包括一种视频编码技术，该视频编码技术具有基本上超过前几代此类标准的压缩能力，并且具有用于在广泛应用中有效使用的足够多功能性。仅规定了语法格式、语义和相关联的解码过程要求，而诸如预处理、编码过程、系统信令和复用、数据丢失恢复、后处理和视频显示等其他事项被认为超出了本文档的范围。另外，在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；只有外部可观察的输出行为需要符合本文件的规范。本文档被设计为通用的，因为它服务于广泛的应用、比特率、分辨率、质量和服务。应用包括但不限于用于数字存储介质的视频编码、电视广播和实时通信。在创建本文档的过程中，考虑了典型应用程序的各种需求，开发了必要的算法元素，并将这些元素集成到单个语法中。因此，本文档旨在促进不同应用之间的视频数据交换。

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.
