Indexing of BdpcmFlag for chroma

Reported by: bheng Owned by:
Priority: minor Milestone:
Component: spec Version: VVC D10 vG
Keywords: Cc: ksuehring, bbross, XiangLi, fbossen, jvet@…


Section includes the following condition:

BdpcmFlag[ xTbCmp ][ yTbCmp ][ cIdx ] is equal to 0;

For chroma, the index [xTbCmp][yTbCmp] used here is a chroma component position. However, everywhere else in the text BdpcmFlag is stored and referenced using a luma position.

Good catch, thanks! I suggest to fix it as follows:

BdpcmFlag[ xTbCmp * ( cIdx > 0 ? SubWidthC : 1 ) ][ yTbCmp * ( cIdx > 0 ? SubHeightC : 1 ) ][ cIdx ] is equal to 0;
