BI-DIRECTIONAL INTER PREDICTION METHOD AND APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18462625 titled 'BI-DIRECTIONAL INTER PREDICTION METHOD AND APPARATUS
Simplified Explanation
The patent application describes a method and apparatus for bi-directional inter prediction in video coding.
- The method involves determining reference picture indices from two reference picture lists and using them to predict the current block.
- The reference picture indices are determined based on their proximity to the picture order count (POC) of the current picture.
- This approach improves coding efficiency in video compression.
Potential Applications
- Video compression and encoding systems
- Multimedia streaming and broadcasting
- Video conferencing and telecommunication
Problems Solved
- Improves coding efficiency in video compression
- Enhances the quality of compressed video
- Reduces bandwidth and storage requirements for video transmission
Benefits
- Higher video compression efficiency
- Improved video quality
- Reduced bandwidth and storage requirements
- Enhanced video streaming and transmission capabilities
Original Abstract Submitted
Embodiments of this application disclose a bi-directional inter prediction method and apparatus. The method includes: determining a reference picture index iof a first reference picture list as a first reference picture index; determining a reference picture index iof a second reference picture list as a second reference picture index; and predicting the current block based on the first reference picture index and the second reference picture index. A POC corresponding to iis a POC, closest to a POC of a current picture, in all POCs that are in the first reference picture list and that are less than the POC of the current picture, a POC corresponding to iis a POC, closest to the POC of the current picture, in all POCs that are in the second reference picture list and that are greater than the POC of the current picture. Coding efficiency can be improved.
