Abstract
Official abstract text for this publication.
A method of selecting reference blocks for intra or inter prediction coding of a current block of a video signal. Each reference blocks is selected by: (i) determining a group of candidate blocks comprising at least some candidate blocks other than immediately adjacent spatial neighbors of the current block; and (ii) selecting one of the candidate blocks as the reference block based on a second metric, different from the first metric, the second metric relating to a number of bits that would be required in the encoded bitstream to encode both the residual block and the side information identifying the respective reference block.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of compressing a video signal, comprising: receiving a video signal comprising a plurality of video frames, each frame representing an image at a different respective time, and each frame comprising a plurality of constituent blocks of the respective image; forming a sorted list of blocks that includes at least a plurality of current blocks to be encoded within a frame of the video signal, the plurality of blocks having both interframe and intrafr…
