Original Abstract Submitted
Aspects of the disclosure include methods and an apparatus for video coding. The apparatus includes processing circuitry that receives coded information of a current block in a current picture. The current block is predicted based on a reference block in the current picture indicated by a block vector (BV) to be determined based on a BV predictor (BVP) and a BV difference (BVD). The processing circuitry determines a BVD list including BVD candidates based at least on BVD offsets from the BVP, determines the BVD from the BVD candidates in the BVD list, and reconstructs the current block using the BVD. For each adjacent pair of the BVD offsets, an initial interval size indicates a difference between the adjacent pair of the BVD offsets. Each of the initial interval sizes is different from other initial interval sizes corresponding to other adjacent pairs of the BVD offsets.
