METHOD AND APPARATUS FOR TEMPORAL INTERPOLATED PREDICTION IN VIDEO BITSTREAM - A simplified explanation of the abstract
This abstract first appeared for US patent application 17982071 titled 'METHOD AND APPARATUS FOR TEMPORAL INTERPOLATED PREDICTION IN VIDEO BITSTREAM
Simplified Explanation
- The patent application is for a video decoder that can decode a video bitstream encoded in a temporal interpolated prediction (TIP) mode. - The decoder generates first and second motion vectors for a block of a current picture, which point to reference frames or reference pictures within those frames. - The motion vectors are then refined using a decoder-side motion vector refinement (DMVR) process, which is based on a bilateral matching process. - The refined motion vectors are used to decode the block of the current picture. - The refinement process involves considering candidates for the refined motion vectors, selected through bilateral matching. - The refinement can be applied at both block and sub-block divisions of the current picture.
Original Abstract Submitted
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.
