Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If hybrid services are introduced in digital broadcasting, then service functionality is improved, but signaling information data size increases
Solution Approach 1:
The signaling information is segmented into two separate transmission paths: broadcast signaling information (first signaling information) transmitted via broadcast wave for broadcast components, and communication signaling information (second signaling information) transmitted via communication for communication components. This segmentation prevents the aggregation of all signaling data through the broadcast channel, thereby suppressing the increase in broadcast signaling data size while maintaining hybrid service functionality.
2Adaptability or versatility
If signaling information includes both broadcast and communication components, then service capability is improved, but transmission efficiency deteriorates
Solution Approach 1:
The system separates signaling information transmission into two independent channels: broadcast wave for broadcast components and communication for communication components. This segmentation allows each channel to transmit only the signaling information relevant to its function, improving transmission efficiency by avoiding unnecessary data transmission while maintaining comprehensive service capability.
Solution Approach 2:
The invention extracts communication component management information from the broadcast signaling information and transmits it separately through communication channels. This extraction removes the burden of transmitting communication-related signaling data through the broadcast channel, thereby improving broadcast transmission efficiency while preserving the ability to manage both broadcast and communication components.
3Device complexity
If all component management information is transmitted through broadcast, then system simplicity is maintained, but data size increases
Solution Approach 1:
The system is segmented into two independent signaling information transmission paths: broadcast wave for broadcast components and communication for communication components. This segmentation maintains relative system simplicity by keeping each transmission path dedicated and purpose-specific, while avoiding the data size increase that would result from consolidating all signaling information in the broadcast channel.
