Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If video quality optimization is performed without feedback on reception status, then transmission complexity is reduced, but transmission accuracy deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where the reception device sends reception status information (packet loss rate, reception quality) back to the transmission device. This enables the transmission device to adjust transmission parameters dynamically based on actual reception conditions, resolving the contradiction by maintaining low complexity through automated feedback-based control while achieving high transmission accuracy.
Solution Approach 2:
The transmission device performs preliminary actions by pre-calculating optimal transmission parameters based on predicted reception status and sending control instructions to the reception device in advance. This allows the system to maintain accurate transmission conditions without requiring complex real-time feedback processing during video streaming.
2Speed
If transmission conditions are set without real-time feedback, then system response time is reduced, but transmission quality deteriorates
Solution Approach 1:
The system implements periodic feedback collection and transmission condition adjustments at predetermined time intervals. This periodic action maintains reliable video transmission quality by regularly updating transmission parameters while keeping the control response speed fast through automated periodic adjustments rather than continuous complex processing.
3Measurement precision
If feedback mechanism is implemented for accurate transmission control, then transmission accuracy is improved, but device complexity increases
Solution Approach 1:
The reception device automatically generates and sends feedback information about its reception status without requiring complex processing from the transmission device. The transmission device simply receives this feedback and adjusts parameters accordingly, maintaining high transmission condition setting accuracy while minimizing the complexity of the feedback system through this self-service approach.
