JVET-AQ0240 Status of SEI messages in the VSEI TuC [J. Boyce]

It was agreed to include all SEI messages and extension in JVET-AQ2006 which are assessed to be mature enough an well understood in usefulness by the criteria that had been defined, as expressed of all fields of the corresponding row marked as green. These elements should be removed in JVET-AQ2032. At this moment, a differential text is defined as WD, which can better be managed than an integrated version.

It is emphasized by software coordinators that the current practice of doing frequent software changes in case of relatively early study on a large number imposes a large amount of work. It would be desirable to have a discussion on practices for implementing SEI messages in software, and potentially having a dedicated software coordinator would be necessary, also to avoid delays in the implementation. To be discussed in a future meeting.
