Abstract:
A video encoder and video decoder may code video data using intra prediction and a block-based delta pulse code modulation (BDPCM) mode. The BDPCM mode may include a vertical mode and a horizontal mode. The video encoder and video decoder may be configured to align the direction of an intra prediction mode to the direction of a BDPCM mode for both luma and chroma blocks.
