Claim 14:
15. An apparatus of processing video data in a video coding system, the apparatus comprising one or more electronic circuits configured for:
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 the current block and the adjacent block are both coded in a Block Differential Pulse Code Modulation (BDPCM) mode or are both coded in a Residual Differential Pulse Code Modulation (RDPCM) mode, wherein each current pixel in each BDPCM coded block in the current picture is predicted by one or more neighboring pixels of the current pixel in the current picture, and RDPCM is applied to quantized residues of each RDPCM coded block according to a prediction direction of the RDPCM coded 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; and
encoding or decoding the current block and the adjacent block in the current picture.
