Abstract: A video decoder is provided for the decoding of a video bitstream encoded in a temporal interpolated prediction (TIP) mode. First and second motion vectors pointing to respective reference frames, or reference pictures within those frames, are generated for a block of a current picture. The motion vectors are then refined by application of a decoder-side motion vector refinement (DMVR) process, based on a bilateral matching process, and the refined motion vectors are used to decode the block. The refinement may more specifically involve consideration of candidates for the refined motion vectors, selected by the bilateral matching. The refinement may be applied at both block and sub-block divisions of the current picture.
