This contribution proposes that the bitdepth range information (BRI) SEI message in the VSEI TuC be included in the initial VSEI version 5 working draft.
Request was withdrawn, obsolete at this moment due to decision on JVET-AQ0096.
General
- After further review of inputs related to the SEI messages and extensions requested to be included, decide which SEI messages and extensions should be selected for inclusion in WD. Based on new modifications proposed, the aspect a (maturity) might need to be re-assessed for certain cases. Only SEI messages and extensions that can be assessed to be sufficiently stable should be included in the first draft of the WD.
- Missing document numbers for showcases should be added
- A table should be created from the criteria a-g for the different proposed messages
Follow-up discussion was conducted in the HLS track on Monday 13 July at 1650, considering the spreadsheet summarizing status of SEI messages proposed for VSEI v5 WD (see under plenary discussion 7.1.2). The following issues were identified:
- The SW availability status of NNPF additional URI tags was wrong in the original table, as indeed software is available.
- The SDI SEI message extensions are considered to be necessary for inclusion in the WD because some other SEI messages that will be included rely on it, including CR and ECFI.
In a follow-up discussion in JVET conducted on Tuesday 14 July 1200. It was agreed to include NNPF additional URI tags in JVET-AQ2006.
As both CR and ECFI are incomplete without being signalled in SDI, it is asserted to be better first working towards full maturity of SDI, and putting the package of all three into the WD by the time that would have been achieved.
Identify potential needs for additional SEI messages, including study of AVC and HEVC SEI messages for use in VVC (11)
