    摘要: Encoding and/or decoding a block of a video frame may be based on a previously decoded reference block in the same frame or a different frame. The reference block may be indicated by a block vector (BV). A block vector difference (BVD) predictor may be used to make predictions about the symbols of one or more magnitude components of a BVD. A quantity of symbols used for BVD magnitude prediction may be limited. The limited quantity of symbols used for prediction may be allocated to one or more of the magnitude components. Allocation of the symbols used for BVD magnitude prediction may be based on the total quantity of symbols used for BVD magnitude prediction and the respective quantities of symbols available for prediction of each of the magnitude components. Symbols of a motion vector difference (MVD) likewise may be predicted.
