Original Abstract Submitted
Aspects of the disclosure provide a method and an apparatus for video coding. In some examples, the apparatus includes processing circuitry for video encoding. The processing circuitry selects a resolution from a set of resolutions that includes a 1-integer-pel resolution and a 4-integer-pel resolution. A current block is encoded with an intra block copy mode based on the selected resolution. The processing circuitry determines a block vector of the current block. The processing circuitry determines a block vector difference of the current block based on the block vector and a block vector predictor of the current block. The block vector difference is in the selected resolution. The processing circuitry encodes prediction information indicating the selected resolution and the block vector difference.
