APPARATUS AND METHOD FOR CONDITIONAL DECODER-SIDE MOTION VECTOR REFINEMENT IN VIDEO CODING - A simplified explanation of the abstract
This abstract first appeared for US patent application 18067458 titled 'APPARATUS AND METHOD FOR CONDITIONAL DECODER-SIDE MOTION VECTOR REFINEMENT IN VIDEO CODING
Simplified Explanation
The patent application describes a method for inter-prediction of image blocks in a video. The method involves determining the temporal distance between a current image block and two reference pictures. If the temporal distances are not equal, a motion vector refinement procedure is not performed.
- The method determines the temporal distance between a current image block and two reference pictures.
- If the temporal distances are not equal, a motion vector refinement procedure is not performed.
- The method restricts the motion vector refinement procedure to only image blocks with equal-distance references.
Potential Applications

- Video encoding and decoding systems
- Video streaming platforms
Problems Solved
- Efficient inter-prediction of image blocks in videos
- Reducing computational complexity in motion vector refinement procedures
Benefits
- Improved video compression efficiency
- Reduced computational requirements for motion vector refinement
- Enhanced video streaming quality and bandwidth utilization
Original Abstract Submitted
A method for inter-prediction of a current image block in a current picture of a video is provided. The method includes determining whether a first temporal distance (such as TD0) is equal to a second temporal distance (such as TD1), wherein the first temporal distance is represented in terms of a difference between a picture order count value of the current picture and a picture order count value of a first reference picture; and the second temporal distance is represented in terms of a difference between a picture order count value of a second reference picture and the picture order count value of the current picture; and performing no motion vector refinement (DMVR) procedure when it is determined that the first temporal distance (TD0) is not equal to the second temporal distance (TD1). Thus the DMVR procedure is restricted to only the image block with equal-distance references.
