ISO/IEC JTC 1/SC 29/WG 5 - MPEG Joint Video Coding Team(s) with ITU-T SG 16

This document specifies a set of tests and procedures designed to indicate whether encoders or decoders meet the requirements specified in Rec. ITU‑T H.266 | ISO/IEC 23090-3.

This document specifies advanced video coding for coding of audio-visual objects.

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.

This document establishes a reference software for Rec. ITU-T H.266 | ISO/IEC 23090-3. NOTE The use of this reference software is not required for making an implementation of an encoder or decoder in conformance to Rec. ITU-T H.266 | ISO/IEC 23090-3. Requirements established in Rec. ITU-T H.266 | ISO/IEC 23090-3 take precedence over the behaviour of the reference software.

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.

This document defines various code points and fields that establish properties of a video (or still image) representation and are independent of the compression encoding and bit rate. These properties can describe the appropriate interpretation of decoded data or can, similarly, describe the characteristics of such a signal before the signal is compressed by an encoder that is suitable for compressing such an input signal.

This document describes common industry representation practices for the usage of video signal type code points, as these properties are conveyed across video content production and distribution carriage systems.

This document provides general information about coding efficiency measurement practices for video coding. This document does not provide recommendations for evaluating video quality; it describes the practices that have recently been followed for coding efficiency experiments conducted during work to develop video coding standards.
