Abstract

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 block residuals for the first set of blocks may be signaled, and the block residuals for subsequently predicted blocks may be signaled. The pixel values for blocks within a set of blocks may be predicted in parallel.
