Claim 13:
14. An apparatus for encoding a video signal, comprising:
a memory storing the video signal, and
a processor coupled to the memory and configured to process the video signal,
wherein the processor is configured to:
check a size of a current block,
determine a prediction mode of the current block based on the size of the current block and a block size permitting an intra block copy (IBC), and
encode information on the prediction mode,
wherein the processor is configured to determine whether an IBC mode is applied based on a rate-distortion cost for the IBC mode when the size of the current block is smaller than or equal to the block size permitting the IBC in order to determine the prediction mode, and
wherein the information on the prediction mode comprises an IBC flag indicating whether the IBC mode is applied.
