7.1Joint Meeting with MPEG Requirements, MPEG Video and VCEG
In a joint meeting session with MPEG Requirements, MPEG Video and VCEG on Wednesday at 1600, the following was recorded.
Hypothetically-applicable JCT-VC docs for scalability issues
JCTVC-F194 Proposal on the support of interlace format in HEVC [S. Sekiguchi, K. Sugimoto, H. Sakate (Mitsubishi)]
JCTVC-F290 Scalability Support in HEVC [D. Hong, W. Jang, J. Boyce, A. Abbas (Vidyo)]
JCTVC-F292 Metrics for evaluation of scalable coding [J. Boyce (Vidyo)] [late upload 07-07]
JCTVC-F096 Scalable structures and inter-layer predictions for HEVC scalable extension [H. M. Choi, J. Nam, D. Sim (Kwangwoon Univ.)]
JCTVC-F618 Resampling filters for scalability and screen content applications [W. Dai, M. Krishnan, P. Topiwala (FastVDO)]
JCTVC-F488 / m20918 Requirements for Scalable extension of HEVC [Edouard Francois, Sebastien Lasserre, Fabrice Le Leannec (Canon)]
m20291 Ad Hoc group recommendations
Phase 1: Multiview & 2D 4:2:0, Phase 2: Chroma and Bit Depth, Phase 3: 3D
Draft CfP Nov; Final CfP Feb …. discussion: Not (final) before Feb.
For MVC we will have a lot more information in Nov.
Conclusion: It was agreed that until after responses to the WG11 3DV CfP (assuming this will happen in a timely fashion), we may include design aspects like, in high-level syntax, ref pic list management, temporal ID, view ID, quality ID, definitions of what subset of the bitstream those apply to, reserved extension bits, but we would not put in scalability-specific coding tools – e.g., specification of upsampling filters for spatial scalability.
Interlace JCTVC-F194 / m20613 and m21411
Without block-level coding changes.
Tested field picture coding (20% better than frame-based for interlaced source).
Possibly include chroma MV alignment
SEI messages (or high-level signalling) don't require formal requirements justification
The requirements docs do not seem to prohibit consideration of interlaced video
Conclusion: We don't have a positive requirement to support interlace, but we are not prohibited from carrying an indicator of interlace.
