Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If video processing capabilities (transcoding, storage, quality testing) are centralized in production studios or centralized video network offices, then device complexity and manufacturing cost are reduced for network devices, but network bandwidth requirements increase and per-user video handling efficiency deteriorates
Solution Approach 1:
The patent segments video processing capabilities from centralized locations and distributes them to network edge devices. Specifically, transcoders, storage systems, and quality testing equipment are deployed at network edges closer to end users, dividing the previously centralized functions into distributed components that operate independently at multiple locations throughout the network.
Solution Approach 2:
The patent introduces a spatial dimension to video processing by moving functions from the centralized horizontal architecture to a distributed hierarchical structure with multiple tiers. Video processing capabilities are placed at network edges, intermediate nodes, and centralized locations simultaneously, creating a multi-dimensional processing architecture that reduces bandwidth consumption through localized processing.
2Adaptability or versatility
If multiple video streams are sent from centralized video source to end user, then service coverage and adaptability are improved, but network bandwidth consumption and costs increase
Solution Approach 1:
The patent implements preliminary video processing at network edge devices before video content reaches end users. Transcoders at the network edge prepare multiple adapted video streams in advance based on predicted user needs and device capabilities, so that when users request video content, already-prepared streams are delivered immediately without requiring real-time transcoding or sending all possible streams from the centralized source.
3Productivity
If video processing capabilities are distributed to network edge devices, then per-user video handling efficiency and bandwidth optimization are improved, but device complexity and manufacturing cost for network devices increase
Solution Approach 1:
The patent designs network edge devices with universal, multi-functional video processing capabilities that can perform transcoding, storage, quality testing, and video delivery across multiple protocols and formats. These edge devices are configured to handle diverse video processing tasks using integrated systems, reducing the need for separate specialized equipment at each network location while maintaining high per-user handling efficiency.
