Parallel Intra-Prediction

摘要

Digital pictures may be encoded and decoded in a way that optimizes parallelization. Selected sections of a digital picture in a first list are encoded independently of encoding any of their neighbor sections. Sections in a second list located to the right of corresponding sections in the first list are encoded using at most the section to their immediate left. Sections in a third list located to the right of a corresponding section in the second list and immediately below a corresponding section in the first list are encoded using at most the sections to the immediate left, immediately above and immediately to its above-right. All other sections of the picture may be encoded in a normal manner.

1. A method, comprising:
encoding selected sections of a digital picture in a first list, wherein each section in the first list is encoded independently of encoding any of its neighbors; encoding selected sections of the digital picture in a second list, wherein each section in the second list is located to the right of a corresponding section in the first list and wherein each section in the second list is encoded using at most the section to its immediate left; encoding selected sections of the digital picture in a third list, wherein each section in the third list is located to the right of a corresponding section in the second list and immediately below a corresponding section in the first list, wherein each section in the third list is encoded using at most the sections to its immediate left, immediately above it and immediately to its above-right; and encoding all other sections of the digital picture.
