Abstract
A system and method for coding a block of video data in block prediction mode for display stream compression (DSC) is disclosed. In one aspect, the method includes determining a candidate block to be used for predicting a current block in a current slice. The candidate block may be within a range of locations defined by one or more block prediction parameters. The method further includes determining, based on the candidate block and the current block, a prediction vector identifying a location of the candidate block with respect to the current block, and coding the current block in block prediction mode at least in part via signaling the prediction vector identifying the location of the candidate block with respect to the current block.
