Claim 0:
1. A decoding apparatus for image decoding, the decoding apparatus comprising:
a memory; and
at least one processor connected to the memory, the at least one processor configured to:
obtain image information; and
generate a reconstructed picture based on the image information,
wherein the obtaining the image information comprises:
obtaining a residual coding flag; and
obtaining syntax elements of a current block according to a residual coding syntax structure determined based on the residual coding flag,
wherein the current block is a transform skip block,
wherein syntax elements according to a regular residual coding syntax structure for the current block are obtained based on the residual coding flag representing that a transform skip residual coding syntax structure is not enabled,
wherein the syntax elements according to the regular residual coding syntax structure include position information on a position of a last non-zero residual coefficient in a residual coefficient array of the current block.
