Abstract:
1. A method for decoding video comprising: (a) decoding a first block of video using a plurality of second blocks of said video, where said plurality of second blocks of said video comprises blocks having different respective sizes relative to each other; (b) decoding a first group of said second blocks in a manner such that each of said first group of said second blocks is predicted independently of the other ones of said second blocks not included within said first group, and where prediction is based upon a first plurality of prediction directions; (c) decoding a second group of said second blocks in manner such that at least one block of said second group of said second blocks is predicted in a manner that is dependent on at least one block of said first group of said second blocks, where said first group of said second blocks does not include any blocks included in said second group of second blocks, and where prediction is based upon a second plurality of prediction directions different from said first plurality of directions; (d) wherein a prediction mode of a selected block from said second group of blocks is based upon a mapping that associates respective directions from said second plurality of directions with respective directions from said first plurality of directions.
