Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If video processing algorithms are applied at both source and sink devices, then video image quality can be improved, but device complexity and power consumption increase
Solution Approach 1:
The system enables automatic selection of video processing algorithms by having each device communicate its capabilities to the other, allowing the recipient device to autonomously determine the optimal processing configuration without manual intervention, thereby resolving the contradiction between quality improvement and complexity management
Solution Approach 2:
The patent dynamically changes the processing parameters by selecting different video processing algorithms based on the communicated capabilities of both devices, allowing the system to adapt the level of processing to achieve optimal quality while managing complexity through intelligent parameter selection
2Manufacturing precision
If video processing algorithms are applied at both source and sink devices, then video image quality can be improved, but power consumption increases
Solution Approach 1:
The system autonomously determines the optimal processing configuration by exchanging capability information between devices, enabling automatic power management decisions that balance video quality improvement with power consumption reduction without user intervention
Solution Approach 2:
The patent applies video processing algorithms selectively rather than universally, enabling processing only when and where it is most beneficial based on the capabilities of both devices, thereby improving quality while minimizing unnecessary power consumption
3Productivity
If video processing capabilities are communicated between devices, then algorithm selection can be optimized, but communication overhead increases
Solution Approach 1:
The patent extracts only the essential capability information needed for algorithm selection and transmits it between devices, removing unnecessary data communication overhead while retaining the critical information required for optimized processing efficiency
Solution Approach 2:
The capability communication mechanism acts as an intermediary that enables optimized algorithm selection by exchanging structured capability information between source and sink devices, facilitating efficient processing decisions with minimal communication overhead

AI summary
At one of a video source device and a video sink device, an indication of video processing capabilities of the other of the video source device and said video sink device is received. Based upon the indication and an indication of video processing capabilities of the one device, one of a plurality of video processing algorithms is selected for execution by the one device. The selecting may be based upon a set of precedence rules. Categories of video processing may for example include scan-rate conversion, interlacing, de-interlacing, de-noise, scaling, color correction, contrast correction and detail enhancement.
