Claim:
1. A method for decoding video data, the method comprising: for a current video block, determining a first most probable intra prediction mode and a second most probable intra prediction mode; receiving one or more codewords indicating that an actual intra prediction mode used to code the current video block is an intra prediction mode other than the first most probable intra prediction mode and other than the second most probable intra prediction mode; in response to the one or more codewords indicating that the actual intra prediction mode used to code the current video block is the intra prediction mode other than the first most probable intra prediction mode and other than the second most probable intra prediction mode, selecting one of the first most probable mode or the second most probable mode as an estimate of the actual intra prediction mode used to code the current video block, wherein selecting the estimate of the actual intra prediction mode comprises: receiving difference information; determining an actual intra prediction mode for the current video block based on the estimate of the actual intra prediction mode and the difference information; and generating a reconstructed video block using the actual intra prediction mode.
