Assignee: LG ELECTRONICS INC.
Field: Audio-visual technology (Electrical engineering)
Classification: CPC H | IPC H

Claim 3:
4. 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 deriving residual samples for a current block, generating information related to the residual samples for the current block, and encoding image information including the information related to the residual samples; and
a transmitter configured to transmit the data comprising the bitstream,
wherein the information related to the residual samples includes information on a multiple transform selection (MTS) index and information on transform coefficients,
wherein the information on the transform coefficients is generated from the residual samples for the current block using a transform kernel set,
wherein the MTS index indicates the transform kernel set among transform kernel set candidates,
wherein at least one bin among bins of a bin string of the MTS index is derived based on a context coding,
wherein the context coding is performed based on a value of a context index increment for the MTS index,
wherein the bin string of the MTS index includes up to 4 bins, and a number of context index increment values allocated to a bin which is derived by the context coding among the 4 bins is one,
wherein a value of the MTS index is represented based on the bin string of the MTS index, and
wherein the value of the MTS index is represented as one of candidates including 0 to 4.
