INTRA PCM (IPCM) AND LOSSLESS CODING MODE VIDEO DEBLOCKING

摘要

PROBLEM TO BE SOLVED: To provide techniques for deblocking filtering on blocks of video data coded using an intra pulse code modulation (IPCM) coding mode and/or a lossless coding mode.SOLUTION: The lossless coding mode uses prediction. The techniques include assigning a non-zero quantization parameter (QP) value for at least one block coded using the coding mode. The techniques also include performing deblocking filtering on one or more of a plurality of blocks of video data on the basis of the coding mode used to code the at least one block and the assigned non-zero QP value for the at least one block.SELECTED DRAWING: Figure 9
