1MPEG-2 Support for 1080/50p/60p

Amendment 3 for MPEG-2 video (enabling a new level for 1080p 50 and 60 fps formats in main profile), as well as the associated conformance testing specifications were progressed to FDAM. Except editorial updates, no changes were made as compared to FPDAM.

2MPEG-4 Simple Studio Profile Levels 5 & 6

The amendment work to support larger formats (beyond 1920x1080) with MPEG-4 simple studio profile, as well as the associated conformance testing specifications, were progressed for FDAM. Except editorial updates, no changes were made as compared to FPDAM.

3MPEG-4 Visual Software and Conformance Maintenance

In the course of the work of the AHG on maintenance of MPEG-4 Visual, another bug fix of software is reported in M15927. It was decided to make this available in the reference software package on the MPEG SVN repository. Problems with another three streams in the visual conformance testing suite were reported as well (minor issue with timing syntax in one frame). It was decided to issue a defect report on this. Corrigenda and/or new editions of visual software and conformance will be issued by an appropriate time. For conformance streams, it is necessary to identify an appropriate facility (SVN preferable) for exchange and downloads.

4Development of AVC

The video subgroup jointly approved the ISO standard related output documents that were produced during the 29^th JVT meeting which was held in parallel. Important work items in this context were

• 
  Final work on reference software for SVC (Study of FPDAM)
  
• 
  Work on MVC software (Study of PDAM) and conformance (PDAM)
  
• 
  Further work on the Cor.1 (Study of DCOR)
  
• 
  Work for new edition, which will include the 2008 edition, Cor.1 and Amd.1 (MVC)
  
• 
  Work for a new amendment (Amd.1 of the new edition), defining the previously discussed Constrained Baseline Profile and a new SEI message defining usage of a checkerboard (quincunx) pattern for interlacing left/right stereo views.
  

On the new SEI message proposal, it is understood that the proposed checkerboard pattern extends over the existing stereo SEI, giving support for another specific type of display. Better understanding will be sought during the development of the amendment about the impact on compression performance, as well as looking for more complete support of stereo interlacing methods that are currently used or expected to be used.

Another profile proposal (brought in M15854) was discussed jointly with the Requirements subgroup. At this moment, the proposals appears to be not sufficiently clear in terms of its technical maturity, as well as its place relative to other AVC profiles, where typically the baseline profile is used for video telephony applications currently.
