1. A method for video encoding, comprising:
determining whether coding of a current block in an intra block copy (IBC) prediction mode is performed in an explicit mode or an implicit mode based on whether a difference exists between a block vector and a corresponding block vector predictor, the current block being part of a current picture to be coded, the coding of the current block being determined to be in the implicit mode when the difference does not exist and being determined to be in the explicit mode when the difference does exist;
constructing a block vector predictor candidate list for the current block based on a sequence of candidates, the block vector predictor candidate list having a first number of block vector predictor candidates in the implicit mode, and having a second number of block vector predictor candidates in the explicit mode;
selecting a block vector predictor candidate from the constructed block vector predictor candidate list and encoding the current block according to the selected block vector predictor candidate; and
encoding, in prediction information of the current block, an index indicating the selected block vector predictor candidate.
