Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video coding technologies face challenges in improving coding efficiency, particularly in handling different chroma components using the same coding scheme, which limits the overall quality of video processing.
Innovation Solution
Implementing different coding schemes for different chroma components within a video block, allowing for independent coding of each component to enhance coding quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the same coding scheme is used for all chroma components, then the coding process is simple and efficient, but the coding quality cannot be optimized for each component
Solution Approach 1:
The patent applies different coding schemes to different chroma components (Cb and Cr) based on their specific characteristics. The Cb component uses a first coding scheme optimized for its properties, while the Cr component uses a second coding scheme optimized for its properties. This local differentiation allows each component to be coded with the most suitable method, improving overall coding quality while maintaining manageable complexity through component-specific optimization
2Manufacturing precision
If different coding schemes are used for different chroma components, then the coding quality is improved, but the coding process becomes more complex
Solution Approach 1:
The patent changes the coding parameters and schemes based on the specific characteristics of each chroma component. By adjusting the coding parameters separately for Cb and Cr components, the system optimizes the balance between coding quality and efficiency for each component, allowing high quality coding while maintaining overall productivity through targeted parameter optimization rather than uniform treatment
