Claim One:
1. A method for processing a video signal, the method comprising: receiving, with a decoding apparatus, the video signal; determining, with the decoding apparatus, a candidate mode list based on intra prediction mode information of neighboring blocks adjacent to a current block, the candidate mode list including at least three candidate prediction modes; parsing, with the decoding apparatus, a mode indication flag of the current block from the video signal, the mode indication flag indicating whether an intra prediction mode of the current block is directly determined from a most probable mode; when the mode indication flag indicates that the intra prediction mode of the current block is not directly determined from the most probable mode: parsing, with the decoding apparatus, first intra prediction mode information of the current block from the video signal; reordering, with the decoding apparatus, the at least three candidate prediction modes such that a lower index is assigned to a candidate prediction mode having a lower value; obtaining, with the decoding apparatus, second intra prediction mode information of the current block from the first intra prediction mode information based on the at least three reordered candidate prediction modes; and decoding, with the decoding apparatus, the current block using the second intra prediction mode information, wherein obtaining the second intra prediction mode information comprises: comparing the first intra prediction mode information with one of the at least three reordered candidate prediction modes, and increasing a value of the first intra prediction mode information by one when the first intra prediction mode information is greater than or equal to the one of the at least three reordered candidate prediction modes.
