2MPEG-4 Simple Studio Profile Levels 5 & 6
The amendment work to support larger formats (beyond 1920x1080) with MPEG-4 simple studio profile was started by the 82nd meeting. Some necessary modifications to the PDAM text were reported in M15097. Furthermore, work on conformance (both for the newly proposed levels, and for improvements for already existing levels) has progressed (M15099). It was decided to issue Study texts for the PDAMs based on these contributions.

Found some problems in the extension after the last meeting. First issue is macroblock number and total number of macroblocks in slice header. Another issue is wrong syntax for intra_DC in case of RGB. Put first issue in Study of PDAM, and second issue in Study of DCOR.

Add new conformance streams for levels 2-4 into Amd.35 (Study of PDAM). Replace the entire table for StuP conformance streams, including marks that the basic functional testing streams also apply to simple StuP.
