| 摘要 |
Aspects of the present invention relate to systems and methods for intra prediction. According to one aspect of the present invention, a macroblock may be partitioned into two, or more, sets of blocks. According to a second aspect of the present invention, when a block is in a first set of blocks, a predicted intra-prediction mode for the block may be predicted based on the intra-prediction modes of available blocks within the first set and of blocks in available neighboring macroblocks. According to a third aspect of the present invention, when a block is in the first set of blocks, a predicted intra-prediction mode for the block may be predicted based on the intra-prediction modes of blocks in available neighboring macroblocks.
