Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If digital broadcasting transmits large amounts of video/audio data, then high definition image and multi-channel audio quality is improved, but data transmission efficiency deteriorates
Solution Approach 1:
The service data is divided into multiple service data blocks, each containing a specific number of service data. This segmentation allows for more efficient transmission and management of large data volumes while maintaining high definition image and audio quality
Solution Approach 2:
The patent introduces a new dimension of organization by creating service data blocks as an intermediate structure between individual service data and the overall broadcast stream. This block-based approach enables parallel processing and more efficient utilization of transmission bandwidth
2Manufacturing precision
If digital broadcasting transmits large amounts of video/audio data, then high definition image and multi-channel audio quality is improved, but network robustness deteriorates
Solution Approach 1:
By segmenting service data into blocks with defined structures including block headers and identifiers, the system enhances network robustness through improved error detection, localization, and recovery capabilities while maintaining high definition content delivery
3Manufacturing precision
If digital broadcasting transmits large amounts of video/audio data, then high definition image and multi-channel audio quality is improved, but network flexibility for mobile receivers deteriorates
Solution Approach 1:
The service data block structure enables dynamic adaptation to mobile receiver requirements through flexible block sizing, adaptive transmission scheduling, and mobile-optimized error correction mechanisms that maintain high definition quality while supporting mobility
Solution Approach 2:
The system allows parameter changes in service data block configuration to optimize for different reception conditions, including mobile environments, while preserving high definition image and audio quality through adaptive encoding and transmission parameters
