The following joint meetings were held (for first three bullets see notes, as applicable, in the corresponding sections)
CD of 23001-11 was reviewed. An SEI message is included in the CD of 23001-11 for AVC, indicating number of zero blocks, number of half pel MC, number of deblocked instances. There is also intent to define a similar message for HEVC, but this has not been done yet Further, a display adaptation (particularly backlight) SEI message is defined The SEI messages could either be conveyed in the video stream or at the systems level. When in the video stream, it is necessary to reserve the corresponding code points in AVC and HEVC. Clarification is needed regarding how that is done – e.g., whether there would there be a reserved number space referring to 23001-11. CICP was raised as a related topic. It was suggested to use a new NAL unit for green metadata in AVC. This was not agreed, as they can be sent as an SEI NAL unit.
