Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the key frame generating frequency is increased to ensure users receive clear video images immediately, then the video quality and user experience improve, but the network bandwidth consumption and server processing load increase
Solution Approach 1:
The patent implements dynamic adjustment of key frame generating frequency based on real-time network conditions. The server monitors network status and adapts the key frame generation rate accordingly - increasing frequency when network conditions are good to ensure video quality, and reducing frequency when bandwidth is constrained. This dynamic approach resolves the contradiction by making the system flexible rather than fixed.
Solution Approach 2:
The invention changes the parameter of key frame generating frequency dynamically. By adjusting this parameter based on network conditions, the system can optimize between video quality and bandwidth consumption. The server can modify the frequency parameter in response to changing network states, thereby resolving the trade-off between maintaining high video quality and conserving network resources.
2Reliability
If the key frame generating frequency is increased to improve video streaming quality, then users see clear video images faster, but the server processing load and system complexity increase
Solution Approach 1:
The server implements self-service mechanisms by automatically monitoring its own processing load and network conditions, then autonomously adjusting the key frame generating frequency without requiring external intervention or complex centralized control. This self-regulating approach reduces system complexity while maintaining optimal video streaming quality.
Solution Approach 2:
The system incorporates feedback loops where the server monitors video streaming quality metrics and network conditions, then uses this feedback to adjust the key frame generating frequency. This closed-loop control enables the server to automatically optimize video quality while managing processing load, resolving the contradiction between quality and complexity.
3Adaptability or versatility
If the key frame generating frequency is dynamically adjusted based on network conditions, then the adaptability and user experience improve, but the control system complexity and implementation difficulty increase
Solution Approach 1:
The patent makes the control system dynamic by enabling real-time adjustment of key frame generating frequency in response to changing network conditions. This dynamic control approach improves network adaptability while keeping the implementation relatively simple through straightforward monitoring and adjustment mechanisms.
Solution Approach 2:
The invention simplifies the control system by focusing on changing a single key parameter (key frame generating frequency) rather than implementing complex multi-parameter control. This single-parameter adjustment approach achieves good network adaptability while minimizing control system complexity and implementation difficulty.
