Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If service-compatible mode is used for 3D broadcast transmission, then compatibility with existing broadcast systems is maintained, but the ability to transmit detailed information about multiplexing modes is insufficient
Solution Approach 1:
The transmission system is segmented into different multiplexing modes (TS-level and ES-level) with specific identification mechanisms for each mode. This segmentation allows the system to maintain compatibility through standardized transmission while providing detailed mode information through mode-specific identification fields and descriptors in the bitstream
Solution Approach 2:
Mode identification fields and descriptors are introduced as intermediary elements that carry detailed information about the multiplexing mode without disrupting the existing service-compatible transmission framework. These intermediaries enable receivers to recognize and adapt to specific multiplexing modes while maintaining backward compatibility
2Adaptability or versatility
If both TS-level and ES-level multiplexing are supported, then flexibility in broadcast transmission is improved, but system complexity increases
Solution Approach 1:
The system dynamically adapts between TS-level and ES-level multiplexing modes based on service requirements and receiver capabilities. Mode switching is enabled through identification fields that allow the transmission system to flexibly select appropriate multiplexing strategies without requiring complex static configuration
Solution Approach 2:
The multiplexing mode is controlled through configurable parameters and identification fields that can be adjusted to switch between TS-level and ES-level multiplexing. This parameter-based control simplifies system management by providing a standardized interface for mode selection rather than requiring complex structural changes
3Reliability
If mode identification is implemented for receiving end, then accurate reception of 3D broadcast is improved, but transmission overhead increases
Solution Approach 1:
Mode identification information is extracted and placed in dedicated, sparsely distributed fields within the bitstream structure rather than being embedded throughout the entire data flow. This extraction approach provides reliable mode recognition at critical points while minimizing the overall quantity of identification data that must be transmitted
