    摘要： Aspects of the present invention relate to systems and methods for intra prediction. According to a first aspect of the present invention, a pixel value, in a first block of a macroblock, may be predicted according to a first-direction intra-prediction mode when a flag has a first value and may be predicted according to a second-direction intra-prediction mode when the flag has a second value, wherein the first-direction intra-prediction mode and the second-direction intra-prediction mode are associated with opposite prediction directions.According to a second aspect of the present invention, a pixel value, in a first block of a macroblock, may be predicted according to a first-direction intra-prediction mode when a flag has a first value and, when the flag has a second value, the pixel value may be predicted based on a weighted average of a first value predicted according to the first-direction intra-prediction mode and a second value predicted according to a second-direction intra-prediction mode, wherein the first-direction intra-prediction mode and the second-direction intra-prediction mode are associated with opposite prediction directions.

    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. The pixel values for a block within a first set of blocks may be predicted using reconstructed values from only neighboring macroblocks. The pixel values for a block within another set of blocks may be subsequently predicted using reconstructed values from blocks in previously reconstructed sets of blocks and/or reconstructed values from neighboring macroblocks. The pixel values for blocks within a set of blocks may be predicted in parallel.

The pixel values for blocks within a set of blocks may be predicted in parallel.
