Residual differential pulse code modulation (DPCM) expansion and harmony with conversion skip, rotation, and scanning

摘要

Techniques for reconciling coding techniques when residual differential pulse code modulation (RDPCM) is applied to residual blocks are described. In some examples, the scan order used for such residual blocks is when the residual block is generated from intra-predicting the current block, and when the residual block inter-predicts the current block or It may be necessary to be the same as that generated from intra block copy prediction.
