Classification: CPC H | IPC H

Claim 16:
17. An apparatus for transmitting data for an image, the apparatus comprising:
at least one processor configured to obtain a bitstream for the image, wherein the bitstream is generated based on generating reconstructed samples including reconstructed luma samples and reconstructed chroma samples of a current block in a current picture, deriving adaptation loop filtering (ALF) filter coefficients for an ALF process, generating ALF-related information based on the ALF filter coefficients, deriving cross-component filter coefficients for a cross-component filtering process, generating cross-component filtering-related information based on the cross-component filter coefficients, and encoding image information to generate the bitstream, wherein the image information includes information for generating the reconstructed samples, the ALF-related information, and the cross-component filtering-related information; and
a transmitter configured to transmit the data comprising the bitstream,
wherein the cross-component filtering-related information includes information on a number of cross-component filters and information on cross-component filter coefficients.
