  • Sign Coding and Decoding Using Prediction
    Publication number: 20240089458
    Abstract: 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 whether the sign of a BVD is positive or negative. The sign of a BVD may be predicted based on a range of values for a magnitude of the BVD and independent of a precise value for the magnitude of the BVD. A motion vector difference (MVD) predictor may be used to make predictions about the sign of an MVD. The MVD may be used with a motion vector predictor (MVP) to indicate a motion vector (MV).
