Standard: MPEG-C
Part: 7

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.

Editions

Edition - 1: Versatile supplemental enhancement information messages for coded video bitstreams

Publication Year: 0
Status: released
Motivations: Supplemental enhancement information contained in this standard is valuable for applications but not mandatory to decode the video bitstream itself.
Objectives: It is targeted to make the supplemental enhancement information contained in this standard shall be usable in combination with various video coding standards, including Versatile Video Coding.

Edition - 3: Versatile SEI 3rd edition

Publication Year: 0
Status: ongoing
Motivations: The new edition is produced for the benefit of industry, integrating additional SEI messages requested, and as such making the text better readible than with a separate amendment. Furthermore, this is beneficial for consistent alignment with the twin text published by ITU-T.
Objectives: To keep the stabdard up to date with newest developments.
