Classification: CPC H | IPC H

Claim 1:
2. An encoding apparatus for image encoding, the encoding apparatus comprising:
a memory; and
at least one processor connected to the memory, the at least one processor configured to:
encode image information; and
generate a bitstream including the encoded image information,
wherein the encoding the image information comprises:
determining whether a transform skip residual coding syntax structure is enabled for a current block in a current slice;
encoding syntax elements of the current block according to a residual coding syntax structure determined based on a result of the determination; and
encoding a residual coding flag for whether the transform skip residual coding syntax structure is enabled for the current block in the current slice,
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 encoded based on a determination that the 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.
