bit_depth_chroma_minus8 syntax inconsistent in monochrome SPS between HM and Text

Reported by: marcin.jasinski Owned by:

Component: HM RExt Version: RExt-7.2 (HM-14.0)

In Text bit_depth_chroma_minus8 is supposed to be alwas present when in HM there is a condition for monochrome and it seems to be proper:

if (chromaEnabled)
    WRITE_UVLC( chromaEnabled ? (pcSPS->getBitDepth(CHANNEL_TYPE_CHROMA) - 8):0,  "bit_depth_chroma_minus8" ); // NOTE: RExt - This SE is not in the SPS header for 4:0:0.


const Bool bChroma=(pcSPS->getChromaFormatIdc() != CHROMA_400);
if (bChroma)
    READ_UVLC( uiCode,    "bit_depth_chroma_minus8" ); // NOTE: RExt - This SE is not in the SPS header for 4:0:0

  • Component changed from RExt text to HM RExt
  • Milestone set to HM+RExt-8.0
  • Version changed from RExt D7 (Q1005) v8 to RExt-7.2 (HM-14.0)

The SPS and PPS have been designed such that there is no requirement to interpret the profile in order to parse them.

The software should be adjusted to match the text.
