Method and apparatus for video coding
Aspects of the disclosure provide methods and apparatuses for video encoding/decoding. In some examples, an apparatus for video decoding includes receiving circuitry and processing circuitry. For example, the processing circuitry decodes prediction information of a current block in a current coding tree unit (CTU) from a coded video bitstream. The prediction information is indicative of an intra block copy mode. A size of the current CTU is smaller than a maximum size of a reference sample memory for storing reconstructed samples. The processing circuitry determines a block vector that points to a reference block in a same picture as the current block. The reference block has reconstructed samples buffered in the reference sample memory. Then, the processing circuitry reconstructs at least a sample of the current block based on the reconstructed samples of the reference block that are retrieved from the reference sample memory.
