APPARATUS AND METHOD FOR ENCODING MOTION VECTOR BY USING BASIC MOTION VECTOR, AND DECODING APPARATUS AND METHOD - A simplified explanation of the abstract
This abstract first appeared for US patent application 18153879 titled 'APPARATUS AND METHOD FOR ENCODING MOTION VECTOR BY USING BASIC MOTION VECTOR, AND DECODING APPARATUS AND METHOD
Simplified Explanation
The abstract describes a method for decoding a motion vector in video coding. Here is a simplified explanation of the abstract:
- The method involves determining a prediction motion vector (PMV) candidate block that is used to determine the PMV of a current block in a video.
- The availability of the motion vector of the PMV candidate block is determined.
- If a PMV candidate block is found to be unavailable, a default motion vector (MV) is used to determine the PMV of the current block.
- Finally, the motion vector of the current block is obtained based on the determined PMV.
Potential Applications:
- Video coding and decoding systems
- Video streaming services
- Video compression technologies
Problems Solved:
- Efficient decoding of motion vectors in video coding
- Handling unavailable motion vectors in a video stream
Benefits:
- Improved video coding efficiency
- Reduced bandwidth requirements for video streaming
- Enhanced video compression techniques
Original Abstract Submitted
A method of decoding a motion vector includes: determining at least one prediction motion vector (PMV) candidate block used to determine a PMV of a current block; determining an availability of a motion vector of the at least one PMV candidate block; when there is a PMV candidate block determined to be unavailable, determining the PMV of the current block by using a default motion vector (MV); and obtaining a motion vector of the current block based on the determined PMV.
