MULTI-REGION SEARCH RANGE FOR BLOCK PREDICTION MODE FOR DISPLAY STREAM COMPRESSION (DSC)

A method for coding a block of video data in simplified block prediction mode of a constant bitrate video coding scheme for transmission over display links is disclosed. In one aspect, the method includes determining a candidate block to be used to predict a current block in a current slice, the candidate block being within a range of pixel positions that each correspond to a reconstructed pixel in the current slice. The range of pixel positions may comprise (i) a first region including one or more first pixel positions in a first line of pixels that overlaps the current block, and (ii) a second region including one or more second pixel positions in a second line of pixels that does not overlap the current block. The method may further comprise determining and signaling a prediction vector indicative of a pixel position of the candidate block.
