Supplemental enhancement information messages for coded video bitstreams

Standard: 
Part number: 
7
Activity status: 
Open
Technologies: 

This standard specifies the syntax and semantics of supplemental enhancement information (SEI) messages. The SEI messages defined in this standard may be conveyed within coded video bitstreams in a manner specified in a video coding specification or may be conveyed by other means as 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.VVC | ISO/IEC 23090-3, although it is drafted in a manner intended to be sufficiently generic that it may also be used with other types of coded video bitstreams.

This document is written in a manner such that it is intended to be referenced by other technical specifications. Such other technical specifications are to be written in a manner to specify certain necessary elements to enable the use of these SEI messages.

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 SEI messages specified in this document is not a required functionality of a video decoder or receiving video system. Although semantics are specified for these SEI messages, decoders and receiving video systems may simply ignore the content of these SEI messages or may use them in some manner not specified in this document.
