Method and apparatus for improvement on decoder side motion derivation and refinement
A method of video decoding for a video decoder includes receiving a coded video bitstream and obtaining, for a current block from the coded video bitstream, one or more initial motion vectors. The method further includes determining whether a decoder side motion vector refinement process is enabled. In response to determining that the decoder side motion vector refinement process is enabled, the method further includes determining whether the one or more initial motion vectors are included in a latency region that indicates a region of one or more blocks having unrefined motion vectors. In response to determining that the one or more initial motion vectors are not included in the latency region, the method further includes performing the motion vector refinement process using the one or more initial motion vectors to generate a plurality of refined motion vectors.
