Subject: [AVTCORE] New Version Notification for draft-ietf-payload-rtp-jpegxs-02.txt

Dear all,

As indicated hereunder, a new version of the JPEG XS RTP payload has been submitted today.

The main difference with previous version is the removal of the EOC marker that shall be discarded from the JPEG XS codestream before RTP transport. Rationale behind this is to avoid having a RTP packet entirely dedicated to the EOC marker (as metadata and entropy coding data are transported in different packets).

There is still a remaining issue to be addressed and for which a new version will be submitted shortly: namely the fact that the current proposal might imply a different number of RTP packets from one frame to the other, which goes against one of the ST2110-22 requirements. One of the solutions we are currently envisioning to tackle this issue would be to allow more than one slice per RTP packet. I’ll keep the reflector informed of the path eventually selected to solve this issue.

Any comment on this matter is welcome.

Kind regards,

Antonin Descampe

Title: RTP Payload Format for ISO/IEC 21122 (JPEG XS)

Abstract:
  This document specifies a Real-Time Transport Protocol (RTP) payload
  format to be used for transporting JPEG XS (ISO/IEC 21122) encoded
  video.  JPEG XS is a low-latency, lightweight image coding system.
  Compared to an uncompressed video use case, it allows higher
  resolutions and frame rates, while offering visually lossless
  quality, reduced power consumption, and end-to-end latency confined
  to a fraction of a frame.

Please note that it may take a couple of minutes from the time of submission
until the htmlized version and diff are available at tools.ietf.org<http://tools.ietf.org>.
