VIDEO DECODING METHOD AND APPARATUS, AND VIDEO ENCODING METHOD AND APPARATUS INVOLVING SUB-BLOCK MERGE INDEX CONTEXT AND BYPASS MODEL - A simplified explanation of the abstract
This abstract first appeared for US patent application 18148937 titled 'VIDEO DECODING METHOD AND APPARATUS, AND VIDEO ENCODING METHOD AND APPARATUS INVOLVING SUB-BLOCK MERGE INDEX CONTEXT AND BYPASS MODEL
Simplified Explanation
The patent application describes a method and apparatus for video decoding that involves encoding and decoding processes.
- The method involves obtaining a first bin, which is arithmetic-encoded using a context model, and represents a candidate motion vector of a sub-block merge mode.
- A second bin is obtained based on the first value obtained by arithmetic-decoding the first bin in a bypass mode.
- A second value is obtained by arithmetic-decoding the second bin in the bypass mode.
- Prediction on a current block is performed in the sub-block merge mode, based on the first value and the second value.
Potential applications of this technology:
- Video compression and decompression algorithms
- Video streaming services
- Video editing and post-production software
Problems solved by this technology:
- Efficient video encoding and decoding processes
- Improved video compression and decompression techniques
- Enhanced video streaming and playback performance
Benefits of this technology:
- Higher video compression ratios, reducing storage and bandwidth requirements
- Improved video quality and resolution
- Faster video encoding and decoding speeds
- Enhanced user experience in video streaming and playback
Original Abstract Submitted
Provided are a video decoding method and apparatus, in which, during video encoding and decoding processes: in which a first bin of a sub-block merge index indicating a candidate motion vector of a sub-block merge mode is obtained, the first bin being arithmetic-encoded using a context model, a second arithmetic-encoded in a bypass mode is obtained based on a first value obtained by arithmetic-decoding the first bin by using the context model, a second value is obtained by arithmetic-decoding the second bin in the bypass mode, and prediction on a current block is performed in the sub-block merge mode, based on the first value and the second value.
