15.0.0.1.1.1.1.1.84m30337 RVC: Updates on HEVC decoder status on conformance test streams [Khaled Jerbi, Damien De Saint Jorre, Mickaël Raulet, Daniele Renzi, Marco Mattavelli, Claudio Alberti]

Conformance (23002-5) amendment is planned to be started once the 23002-4 amendment is complete. The exercise uses available HEVC conformance streams, most of which already pass without errors through the RVC implementation of HEVC.

1. Jointly-discussed requirements-related issues

• 
  HEVC range extensions profiles were discussed. It was suggested for JCT-VC to identify a somewhat-reduced set of profiles relative to those proposed in JCTVC-N0191 for specification action at the current meeting, and for the remainder to be considered in further study.
  
  • 
    Separate colour plane mode should be prohibited.
    
  • 
    Aux pics (if specified) should not be profiled (at the moment).
    
  • 
    Define the following new profiles:
    
    • 
      4:4:4/10, 12
      
    • 
      4:2:2/10, 12
      
    • 
      4:2:0/12 (note that 8 and 10 bit profiles have already been specified)
      
  • 
    The 4:2:2 and 4:4:4 cases should have 1.25 and 1.5 times the bit rate capability and half the minimum compression ratio MinCr requirement
    
  • 
    The maximum CPB size should not be increased for the 4:2:2 and 4:4:4 cases – so, in these cases, the maximum CPB size will be less than a 1 second buffer at the max bit rate.
    
  • 
    It was suggested to use one profile_idc for a syntax family, and use constraint flags for subset profiles within that (when feasible).
    
  • 
    It was remarked that intra-only is also very desirable to consider (for further study).
    
• 
  JCTVC-N0050 also has aspects related to profile/level (for use of an AVC base layer in an SHVC video context). There remains an interest in enabling hybrid codec scalability, although some specifics need to be sorted out.
  
• 
  There is keen interest in further work on screen content coding (SCC) as a focus of development (versus designing a "generic" video coding standard intended to handle a broad range of applications). WG 11 is developing a plan to issue a Call for Proposals for new work on the subject. Members of both parent bodies expressed an interest in this work, and potentially in conducting it jointly.
  
• 
  Work has been progressing in WG 11 regarding the potential benefit for modification of HEVC for improving the coding efficiency of coding interlaced video, and the study will be continued.
  
• 
  The potential use of the "tiled" frame packing arrangement with HEVC for stereoscopic video coding has been under discussion at the parent body level, and a suggestion under consideration in WG 11 was to specify such an indication in a separate SEI message rather than adding it to the existing frame packing arrangement SEI message.
  
• 
  A proposal had been submitted to both WG 11 and VCEG regarding still picture coding with HEVC. It was agreed to move forward toward specification of a "level 8.5" with unlimited picture size, for which decoding is optional but normatively specified if decoded. Other aspects, including tiling constraints, are for further study.
  
• 
  "Best effort" decoding with degraded quality remains under investigation for potential action.
  
• 
  3D-HEVC beyond multi-view, and ultra-multiview video coding has been investigated in some recent work.
  
• 
  Input was received by WG 11 and VCEG regarding using a different sort of color representation for coded video content than has typically been used in past practice. This has sometimes been referred to as the coding of XYZ video content.
  
• 
  3GPP is evaluating the possibility of using HEVC and may request the specification of another tier/level of HEVC.
