Claim 15:
16. An apparatus for transmitting data for an image, the apparatus comprising:
at least one processor configured to obtain a bitstream generated based on deriving prediction samples for a current block based on prediction mode information, deriving residual samples based on the prediction samples, deriving transform coefficients based on the residual samples, deriving quantized transform coefficients through a quantization process based on the transform coefficients, and encoding image information including residual information generated based on the quantized transform coefficients and the prediction mode information to generate the bitstream; and
a transmitter configured to transmit the data comprising the bitstream,
wherein the image information includes an adaptation parameter set (APS),
wherein the APS is identified based on APS ID information related to an identifier of the APS,
wherein the APS includes scaling list data based on APS type information for APS parameters included in the APS, and
wherein a range of values of the APS ID information is determined based on the APS type information.
