1. A method of video encoding, the method comprising:
receiving input data related to a current block in a current picture;
signaling, at a high level in a video bitstream, a first syntax regarding residual coding type;
determining a residual coding type of a block that is coded with transform skip mode or DPCM mode;
in response to the current block is coded with transform skip mode or DPCM mode,
encoding the current block by using the residual coding type indicated in the first syntax, wherein the residual coding type of a block that is not coded in the transform skip mode or DPCM mode remain unchanged regardless of the first syntax value.
