1. A method for processing a video signal comprising:
receiving intra prediction mode information for a current block indicating one of a plurality of intra prediction modes including a basic angle mode corresponding to an angle within a preset angle range;
determining an extended angle mode based on a sum of an index of the basic angle mode corresponding to the intra prediction mode information and a predetermined offset; and
obtaining a prediction sample of the current block based on the extended angle mode,
wherein the extended angle mode indicates a wide angle direction outside the preset angle range.
