Abstract

In a method for video decoding in a decoder, reconstructed samples of a reconstructed block of a picture are stored. When a current sub-block in a current block of the picture is to be reconstructed using intra block copy (IBC) based on a reference sub-block in the reconstructed block, the reference sub-block for the current sub-block is identified, whether the reconstructed samples of the reference sub-block stored are indicated as overwritten is determined based on a position of the current sub-block, reconstructed samples of the current sub-block for output are generated based on the reconstructed samples of the reference sub-block when the reconstructed samples of the reference sub-block stored are determined to be indicated as not overwritten, and the reconstructed samples of a collocated sub-block in the reconstructed block stored are overwritten with the generated reconstructed samples of the current sub-block.
