摘要

A system encoding and decoding video that uses a parallel encoding and decoding technique.

主权项

1. A method for decoding video comprising:
(a) decoding a first block of video using a plurality of second blocks of said video; (b) decoding a first group of said second blocks such that each of said first group of said second blocks is predicted in a first manner such that prediction is independent of the other ones of said second blocks not included within said first group of said second blocks, prediction based upon selection of a prediction direction from among a plurality of prediction directions; (c) decoding a second group of said second blocks such that at least one block of said second group of said second blocks is predicted in a second manner such that prediction is dependent on the other ones of said second blocks not included in said second group of said second blocks, where said first group of said second blocks does not include any blocks included in said second group of said second blocks, and where prediction is based upon selection of a prediction direction from among a plurality of prediction directions; and (d) selecting one of a first scan order and a second scan order different from said first scan order when decoding a selected one of said second plurality of blocks, selection based upon which of said plurality of prediction directions was selected for said selected one of said second plurality of blocks.
