Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If digital broadcast systems transmit large amounts of video/audio data, then service quality is improved, but data transmission efficiency deteriorates
Solution Approach 1:
The patent segments broadcast services into different categories (first broadcast services and second broadcast services) with different transmission characteristics. First broadcast services use unicast transmission for reliable delivery, while second broadcast services use multicast transmission for efficiency. This segmentation allows optimized transmission for each service type, resolving the contradiction between data quantity and transmission efficiency.
Solution Approach 2:
The patent changes transmission parameters based on service characteristics by introducing a service category indication in signaling information. The receiver adjusts transmission parameters (unicast vs. multicast, quality of service levels) according to the service category, enabling efficient transmission of large data amounts for appropriate service types while maintaining reliability for others.
2Quantity of substance
If digital broadcast systems provide HD images and multichannel audio, then service quality is improved, but network robustness deteriorates
Solution Approach 1:
The patent segments services into two categories with different robustness requirements. First broadcast services (requiring higher robustness) use unicast transmission with dedicated resources, while second broadcast services (tolerating lower robustness) use multicast. This segmentation allows HD content to be delivered reliably when needed while using efficient multicast for less critical services.
Solution Approach 2:
The patent provides beforehand cushioning by establishing quality of service parameters and transmission modes in advance through signaling information. The receiver pre-configures reception parameters based on service category, ensuring robust reception for first broadcast services while optimizing for second broadcast services, thus preventing reception failures before they occur.
3Adaptability or versatility
If broadcast systems support mobile reception equipment, then network flexibility is improved, but transmission robustness deteriorates
Solution Approach 1:
The patent segments broadcast services based on reception scenario requirements. Services suitable for mobile reception (less demanding on robustness) are transmitted via multicast, while services requiring high robustness use unicast. This segmentation enables the system to support mobile devices without compromising the reliability of critical services.
Solution Approach 2:
The patent introduces dynamic transmission mode selection based on reception conditions. The receiver determines the appropriate transmission mode (unicast or multicast) based on service category and current reception environment, allowing flexible adaptation to mobile scenarios while maintaining robustness when needed through dynamic decision-making.
