Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If 3D video content is distributed across multiple service providers and devices with different infrastructure and transmission formats, then the reach and accessibility of 3D content is improved, but the stereoscopic effect quality deteriorates due to format incompatibilities
Solution Approach 1:
The system segments the 3D video signal into separate left-eye and right-eye video streams, allowing independent processing and optimization for different transmission formats. This segmentation enables each eye's signal to be handled according to specific device requirements while maintaining overall stereoscopic quality
Solution Approach 2:
A centralized production system acts as an intermediary between content creation and multiple distribution channels. This intermediary processes and formats the 3D content appropriately for different service providers and devices, ensuring stereoscopic effect preservation across diverse infrastructure
2Ease of operation
If signal processing and formatting are distributed across multiple on-site locations, then local flexibility is improved, but equipment complexity and resource requirements worsen
Solution Approach 1:
The system merges multiple signal processing functions (multiplexing, audio synchronization, compression, file capture) into a centralized production location. This consolidation eliminates the need for complex equipment at distributed on-site locations, reducing local equipment complexity while maintaining processing capabilities
Solution Approach 2:
Complex signal processing functions are extracted from distributed on-site locations and centralized in a single production facility. This extraction removes the burden of maintaining complex equipment at multiple locations while preserving the ability to perform necessary processing
3Adaptability or versatility
If multiple service providers access the same 3D content through different protocols, then content distribution reach is improved, but synchronization and format consistency worsen
Solution Approach 1:
The centralized production system performs preliminary formatting and synchronization of 3D video signals before distribution to multiple service providers. By pre-processing the content into appropriate formats and ensuring synchronization at the source, the system maintains signal consistency across different protocols and providers
