Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video coding technologies, such as MPEG-2, MPEG-4, ITU-T H.263, ITU-T H.264/MPEG-4 AVC, and ITU-T H.265 HEVC, require improvements in coding quality for video processing.
Innovation Solution
A method is proposed that applies a pruning check on motion candidates for video blocks based on coding mode information of reference blocks, enhancing the pruning process and diversifying motion candidates, thereby improving coding quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional pruning check is applied without considering coding mode information, then the processing is simpler and faster, but the motion candidates are limited and coding quality is not optimized
Solution Approach 1:
The patent applies parameter changes by incorporating coding mode information (intra mode, inter mode, skip mode) as additional parameters into the pruning check process. This allows the pruning check to consider multiple coding modes when evaluating motion candidates, thereby improving coding quality while maintaining a structured and manageable process complexity through systematic parameter integration
2Manufacturing precision
If motion candidates are diversified through comprehensive pruning check, then coding quality improves, but the processing time and computational complexity increase
Solution Approach 1:
The patent implements preliminary action by performing pruning check operations before final motion candidate selection. By pre-evaluating motion candidates against multiple coding modes and reference blocks in advance, the system identifies and eliminates unsuitable candidates early in the process, reducing the overall computational burden and processing time while ensuring high coding quality through thorough initial screening

AI summary
Embodiments of the present disclosure provide a solution for video processing. A method for video processing is proposed. The method comprises: applying, for a conversion between a current video block of a video and a bitstream of the video, a pruning check on a first motion candidate and a second motion candidate for the current video block based on coding mode information of a first reference block associated with the first motion candidate and coding mode information of a second reference block associated with the second motion candidate; and performing the conversion based on the applying.
