Classification: CPC H | IPC H

Claim 11:
12. A transmission method of data for an image, the method comprising:
obtaining a bitstream for the image, wherein the bitstream is generated based on prediction samples for a current block; and encoding image information including a Block-based Delta Pulse Code Modulation (BDPCM) enabled flag; and
transmitting the data including the bitstream of the image information including the BDPCM enabled flag,
wherein the BDPCM enabled flag is a flag indicating whether BDPCM is enabled for both a luma block and a chroma block within a current sequence or not,
wherein, in response to a case where the BDPCM enabled flag indicates that the BDPCM is enabled for both the luma block and the chroma block within the current sequence, the bitstream of the image information further includes a BDPCM luma flag indicating whether the BDPCM is applied to a current luma block belonging to the current block and a BDPCM chroma flag indicating whether the BDPCM is applied to current chroma blocks belonging to the current block.
