Classification: CPC H | IPC H

Claim 6:
7. A method of encoding video data, the method comprising:
determining, for a first block of a picture, a maximum block size used for a transform skip mode, wherein the maximum block size is limited to a range of sizes from 4 to 32;
determining, for a second block of the picture, a maximum block size for a block-based delta pulse code modulation (BDPCM) mode based on the maximum block size used for the transform skip mode;
based on the maximum block size for the transform skip mode, include a BDPCM mode flag in a bitstream of the encoded video data in response to a size for the second block being less than or equal to the maximum block size for the BDPCM mode; and
encoding the second block based on the determined maximum block size for the BDPCM mode, wherein encoding the second block based on the determined maximum block size for the BDPCM mode comprises generating, for inclusion in a sequence parameter set syntax structure applying to the picture, a syntax element indicating the maximum block size used for both the transform skip mode and the BDPCM mode.
