Method and apparatus for block vector prediction with integer offsets in intra picture block compensation
A method of video decoding performed by a video decoder includes receiving a coded video bitstream containing a current picture. The method includes determining whether a current block in the current picture is coded in intra block copy (IBC) mode. The method includes in response to a determination that the current block is coded in IBC mode, determining whether a mode with a motion vector offset is enabled for the IBC encoded current block. The method further includes in response to a determination that the mode with the motion vector offset is enabled for the IBC encoded current block, decoding the current block in accordance with an offset associated with the current block. Furthermore, the fractional offsets are not permitted for the IBC encoded current block.
