METHOD AND DEVICE FOR ENCODING/DECODING MOTION VECTOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 17972013 titled 'METHOD AND DEVICE FOR ENCODING/DECODING MOTION VECTOR
Simplified Explanation
The patent application describes a motion vector encoding apparatus that predicts and encodes motion vectors in video compression. Here are the key points:
- The apparatus uses a predictor to determine motion vector predictor candidates based on a spatial candidate block and a temporal candidate block of a current block.
- The motion vector predictor candidates are used to determine the motion vector predictor, motion vector, and motion vector resolution of the current block.
- An encoder then encodes information related to the motion vector predictor, the residual motion vector between the actual motion vector and the predictor, and the motion vector resolution of the current block.
- The motion vector resolutions include a higher resolution than the traditional one-pel unit, allowing for more accurate motion estimation.
Potential applications of this technology:
- Video compression and encoding algorithms
- Video streaming services
- Video conferencing and telecommunication systems
Problems solved by this technology:
- Improved accuracy in motion estimation for video compression
- Efficient encoding of motion vectors in video data
- Reduction in bandwidth and storage requirements for video transmission and storage
Benefits of this technology:
- Higher quality video compression with more accurate motion estimation
- Reduced bandwidth and storage requirements for video transmission and storage
- Improved video streaming and video conferencing experiences with smoother motion playback.
