CSA ISO/IEC 21122-3:20
Information technology — JPEG XS low-latency lightweight image coding system — Part 3: Transport and container formats (Adopted ISO/IEC 21122-3:2019, first edition, 2019-08)
Standards development within the Information Technology sector is harmonized with international standards development. Through the CSA Technical Committee on Information Technology (TCIT), Canadians serve as the SCC Mirror Committee (SMC) on ISO/IEC Joint Technical Committee 1 on Information Technology (ISO/IEC JTC1) for the Standards Council of Canada (SCC), the ISO member body for Canada and sponsor of the Canadian National Committee of the IEC. Also, as a member of the International Telecommunication Union (ITU), Canada participates in the International Telegraph and Telephone Consultative Committee (ITU-T).
At the time of publication, ISO/IEC 21122-3:2019 is available from ISO and IEC in English only. CSA Group will publish the French version when it becomes available from ISO and IEC.
This Standard has been formally approved, without modification, by the Technical Committee and has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.
This document defines transport and container formats for JPEG XS code streams as specified in ISO/IEC 21122-1. It defines file formats for working with still image and motion image sequence files on computer platforms and gives guidance on how to embed the code stream in transport streams, allowing internet-based communication.
This document uses already existing specifications for file formats and extends them for the embedding of JPEG XS code streams.
