HEVC-UHD-Dec in MV-HEVC OP probably redundant and to be removed

Current definitions:

MV-HEVC-Main-Dual-layers-UHD420-Dec: the capability to decode bitstreams with

  • an HEVC/ITU-T H.265 Main 10 Profile base layer (nuh_layer_id==0),
  • and a single enhancement layer (nuh_layer_id!=0) that is tagged as an HEVC/ITU-T H.265 Multiview Main 10 layer [5],
  • where each layer conforms to Main Tier, Level 5.1 and where UE should be capable of supporting single layer decoding of HEVC/ITU-T H.265 Main 10 Profile bitstreams at Main Tier, Level 5.2.

HEVC-UHD-Dec: the capability to decode

  • a bitstream containing a single sub-bitstream conforming to HEVC/ITU-T H.265 Main 10 Profile, Main Tier, Level 5.1 [5] with progressive constraints as defined in clause 4.5.3, or
  • a bitstream containing multiple layers where the base layer sub-bitstream conforms to HEVC/ITU-T H.265 Main 10 Profile, Main Tier, Level 5.1 [5] with progressive constraints as defined in clause 4.5.3.
  1. The bitstream shall contain a first output layer set containing the layer (nuh_layer_id = 0) which follows the constraints specified in the HEVC-UHD-Dec decoding capabilities as defined in clause 5.3.2.
