FIXED BIT DEPTH PROCESSING FOR CROSS-COMPONENT LINEAR MODEL (CCLM) MODE IN VIDEO CODING

Abstract:

A video decoder can be configured to determine that a first block of the video data is encoded in a cross component linear model (CCLM) mode; determine that the first block has a first bit depth; determine that a second block of the video data is encoded in the CCLM mode; determine that the second block has a second bit depth that is different than the first bit depth; and decode the first block and the second block in the CCLM mode using a fixed bit depth, wherein the fixed bit depth is different than at least one of the first bit depth or the second bit depth.
