Claim 0:
1. An image decoding method performed by a decoding apparatus, the method comprising:
obtaining a dependent quantization enabled flag;
obtaining a Transform Skip Residual Coding (TSRC) disabled flag based on the depenendent quantization enabled flag;
obtaining residual information for a current block based on the TSRC disabled flag;
deriving a residual sample of the current block based on the residual information; and
generating a reconstructed picture based on the residual sample,
wherein the depenendent quantization enabled flag is a flag for whether depenendent quantization is enabled,
wherein the TSRC disabled flag is a flag for whether TSRC is used,
wherein the TSRC disabled flag is obtained from a bitstream based on a value of the depenendent quantization enabled flag being equal to 0,
wherein the TSRC disabled flag having a value of 1 represents that the TSRC is not used, and
wherein the TSRC disabled flag having the value of 0 represents that the TSRC is used.
