Aspects of the disclosure provide a method and an apparatus including processing circuitry for video decoding. The processing circuitry is configured to decode coding information for a current block of a current picture. The coding information can indicate a coding mode for the current block being one of: an intra block copy (IBC) mode and a string copy mode. The processing circuitry is configured to determine current vector information for a current unit of samples in the current block based on the coding mode for the current block and a history buffer. The history buffer can be configured to store vector information of at least a block previously decoded in the IBC mode and a string previously decoded in the string copy mode. The processing circuitry is configured to reconstruct the current unit of samples based on the current vector information.
