Claim 7:
8. A method of processing video data in a video coding system, comprising:
receiving input data associated with a current block and an adjacent block in a current picture, wherein the adjacent block is spatially adjacent to the current block;
determining if the current block and the adjacent block are both coded in a Residual Differential Pulse Code Modulation (RDPCM) mode, wherein RDPCM is applied to quantized residues of the current block according to a prediction direction of the current block, and RDPCM is applied to quantized residues of the adjacent block according to a prediction direction of the adjacent block;
performing a deblocking filtering operation on an edge between the current block and the adjacent block by de-activating deblocking filtering for a first color component on the edge between the current block and the adjacent block and activating deblocking filtering for a second color component on the edge between the current block and the adjacent block when the current block and the adjacent block are coded in a RDPCM mode; and
encoding or decoding the current block and the adjacent block in the current picture.
