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.

Abstract: This disclosure generally describes a set of advanced video coding technologies, and is specifically related to cross-component sample offset (CCSO) filtering. For example, a CCSO filter having fractional CCSO filtering tap positions may be used to generate sample offsets from one color component of a reconstructed video. The sample offsets may then be applied to a second color component of the reconstructed video. The reconstructed samples of the first color component may first be interpolated by an interpolation filter in order to generate interpolated samples of the first color component at the fractional CCSO tap positions. The interpolated samples may be used as input to the CCSO filter for the generation of the sample offsets.

The current coding block is reconstructed at least by adjusting the first color sample based on the first sample offset.
