Abstract:
This disclosure describes techniques for coding video data according to an intra Block Copy (BC) coding mode. A block vector difference that identifies a prediction block may be represented by a plurality of syntax elements, which may be encoded and decoded. This disclosure proposes various techniques whereby a video encoder may conditionally signal syntax elements representing the absolute value and/or sign of the components of the block vector difference. Likewise, a video decoder may be configured to infer the values of the syntax elements representing the absolute value and/or sign of the components of the block vector difference when such syntax elements are not signaled.
