Usage of BitDepthC when ChromaArrayType is equal to 0

Reported by: davidf Owned by:
Priority: minor Milestone: RExt D7
Component: RExt text Version: RExt D4 (N1005) v3
Keywords: Cc: davidf, joels@…, teruhikos@…


The value and use of BitDepthC needs attention when ChromaArrayType is equal to 0:

  • bit_depth_chroma is not used in the decoding process and decoders shall ignore its value
  • BitDepthC shall be 0
  • Don't define CoeffMinC, CoeffMaxC
  • Update Generation of one unavailable picture to only generate a monochrome picture
  • Update D.3.8 Recovery point SEI message semantics, NOTE3
  • Check VUI colour matrix definition and usage of BitDepthC. For the purposes of this subclause, BitDepthC may need to have the value of BitDepthY (See also Clip1C).
