MoQ MPEG-TS Catalog Extension rev 00 lands on the IETF Datatracker
This document defines the mpegts catalog section, which records what demultiplexing an MPEG-2 Transport Stream [mpeg2] into a MoQ broadcast would otherwise lose: each track's PID and PMT descriptors, the program identity, the service information tables, and a carriage record for every elementary stream the publisher did not decode. It is a root member of either the hang catalog [hang] or the MSF catalog [msf], so a subscriber that ignores it still plays the broadcast and one that reads it can rebuild the source multiplex.
