METHOD OF RESIDUE DIFFERENTIAL PULSE-CODE MODULATION FOR HEVC RANGE EXTENSION

摘要

A method of RDPCM (Residue Differential Pulse-Code Modulation) coding incorporating unified Intra and Inter RDPCM coding is disclosed. The same RDPCM encoding and decoding steps in the same processing order are applied to blocks coded in the Intra prediction mode and Inter prediction mode/IntraBC prediction mode (Intra-block copy mode). A method of extending Inter RDPCM coding to blocks coded in the IntraBC prediction mode. RDPCM processing in the vertical or horizontal direction is applied to IntraBC residue.
