Method and apparatus for video coding

An apparatus of video decoding, comprising:

• processing circuitry configured to:
• decode prediction information of a current block of a current coding region in a coded video bitstream, the prediction information being indicative of an intra block copy mode;
• determine a block vector that points to a reference block in a same picture as the current block, the reference block being located within a search range, the search range including reconstructed samples of coding regions comprising a coding tree unit (CTU) of the current block and reconstructed samples of at least one coding region comprising a CTU adjacent to the CTU of the current block;
• reconstruct at least a sample of the current block based on reconstructed samples of the reference block;
• and
• updating the search range for reconstruction of a next coding region such that reconstructed samples of the current block are included in the updated search range and the reconstructed samples of the at least one coding region comprising the CTU adjacent to the CTU of the current block are not available in the updated search range.
