Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual broadcast directing is used with multiple camera positions, then comprehensive multi-angle coverage is achieved, but labor costs increase and real-time performance decreases
Solution Approach 1:
The system performs self-service by automatically selecting and switching between camera positions based on event recognition. The broadcast directing system autonomously monitors video streams, identifies events, and generates switching commands without human intervention, thereby achieving real-time multi-angle coverage while reducing labor costs
Solution Approach 2:
The patent replaces the mechanical manual operation system with an automated computer vision system. Event recognition algorithms and automatic switching logic substitute for the manual work of directors and editors, enabling real-time broadcast directing through automated event detection and camera position selection
2Measurement precision
If multiple camera positions are monitored manually, then event detection accuracy is improved, but time consumption increases
Solution Approach 1:
The system maintains continuous monitoring of all camera positions simultaneously through automated event recognition. Multiple video streams are processed in parallel by the system, ensuring that events are detected continuously without the time loss associated with manual switching between cameras
Solution Approach 2:
The system creates digital copies of video streams from multiple camera positions and processes them concurrently through event recognition algorithms. This allows simultaneous analysis of all camera feeds without the time consumption of manual review, maintaining high event detection accuracy
3Manufacturing precision
If automated event recognition is implemented, then broadcast directing accuracy is improved, but system complexity increases
Solution Approach 1:
The system segments the broadcast directing task into distinct modules: video stream acquisition, event recognition, camera position selection, and video switching. Each module performs a specific function, and the segmentation allows the complex automated system to achieve high directing accuracy through coordinated operation of simpler subsystems
