DECODER-SIDE CONTROL POINT MOTION VECTOR REFINEMENT FOR AFFINE INTER-PREDICTION IN VIDEO CODING - A simplified explanation of the abstract
This abstract first appeared for US patent application 18476931 titled 'DECODER-SIDE CONTROL POINT MOTION VECTOR REFINEMENT FOR AFFINE INTER-PREDICTION IN VIDEO CODING
Simplified Explanation
The example device for decoding video data described in the abstract utilizes a processing system to refine control point motion vectors (CPMVs) of video data using decoder-side motion vector refinement (DMVR) processes, form prediction blocks, and decode video blocks.
- The processing system refines a first CPMV of a current block using a first DMVR process to form a first refined CPMV.
- It refines a second CPMV of the current block using a second DMVR process independently of the first DMVR process to form a second refined CPMV.
- A prediction block for the current block is formed using the first and second refined CPMVs.
- The current block is decoded using the prediction block.

Original Abstract Submitted
An example device for decoding video data includes a memory configured to store video data; and a processing system comprising one or more processors implemented in circuitry, the processing system being configured to: refine a first control point motion vector (CPMV) of a current block of the video data using a first decoder-side motion vector refinement (DMVR) process to form a first refined CPMV for the current block; refine a second CPMV of the current block of video data using a second DMVR process, independently of the first DMVR process, to form a second refined CPMV for the current block; form a prediction block for the current block using the first refined CPMV and the second refined CPMV; and decode the current block using the prediction block. In some examples, the CPMVs may each be decoded using a respective merge index and a respective motion vector difference (MVD).
