  • Block Vector Difference (BVD) Indication with Reduced Overhead
    Publication number: 20240155131
    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 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 comprise a null component, for example, based on the BV comprising a null component. Signaling overhead may be reduced by indicating whether the BV comprises a null component and/or a direction of the null component.
    Type: Application

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 comprise a null component, for example, based on the BV comprising a null component. Signaling overhead may be reduced by indicating a difference between non-null components of the BVP and the BV.

  • Block Vector Predictor Candidate Selection
    Publication number: 20240031557
    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 in a different frame. The reference block may be indicated by a block vector (BV). The BV may be encoded as difference between a block vector predictor (BVP) and the BV. The BVP may be selected based on a distance between the BVP and another BVP which may improve diversity of selected BVPs and improve prediction accuracy of the BVP.
