Original Abstract Submitted
Encoding and/or decoding a block of a video frame may be based on a previously decoded reference block in the same frame or in a different frame. The reference block may be indicated by a block vector (BV). The BV may be encoded as difference (e.g., block vector difference (BVD)) between a block vector predictor (BVP) and the BV. The BVP may indicate a codeword comprising a prefix part and a suffix part. Efficient entropy coding may be achieved by selectively using variable length coding for the prefix part and the suffix part. For example, variable length coding for the prefix part and the suffix part may be used if the prefix part indicates a maximum prefix value.
