Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all metadata for video data processing is transmitted to the receiver, then the receiver can access complete video processing information, but the data transmission load and processing complexity increase significantly
Solution Approach 1:
The transmitter extracts and transmits only the necessary subset of metadata required for the receiver to perform video processing, rather than transmitting all available metadata. This reduces the data load on the receiver while maintaining the essential information needed for HDR and WCG processing.
Solution Approach 2:
The metadata is segmented into different types and categories (e.g., HDR metadata, WCG metadata, basic video parameters). The receiver can then selectively acquire only the metadata segments it needs based on its capabilities and the specific processing requirements, reducing overall processing complexity.
2Manufacturing precision
If comprehensive metadata is transmitted for HDR and WCG processing, then video quality enhancement is achieved, but data transmission efficiency decreases
Solution Approach 1:
The transmitter extracts only the essential metadata elements required for HDR and WCG processing and transmits them to the receiver. This selective transmission maintains video quality enhancement capabilities while reducing the overall data transmission volume and improving transmission efficiency.
3Manufacturing precision
If the receiver processes all received metadata, then complete video processing capability is achieved, but processing time and computational resources increase
Solution Approach 1:
The receiver extracts and processes only the necessary metadata elements from the received data stream, ignoring unnecessary metadata. This selective processing approach maintains high video processing quality while significantly reducing the time and computational resources required.
Solution Approach 2:
The receiver dynamically determines which metadata to process based on its own capabilities, the type of content being received, and the specific processing requirements. This dynamic selection optimizes processing efficiency while maintaining video quality.
