Abstract:
An apparatus for video decoding includes processing circuitry. The processing circuitry can be configured to receive data of a current block coded with an intra block copy (IBC) mode in a bitstream. A block vector of the current block can be determined based on a history-based block vector prediction (HBVP) table that includes one or more entries each corresponding to a previously decoded block. Each entry can include a block vector of the corresponding previously decoded block and a location of the corresponding previously decoded block. The current block can be reconstructed based on the determined block vector of the current block.
