Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If video transmission platforms use buffering to relay end-to-end video transmission, then video stability is improved, but transmission delay increases and real-time performance deteriorates
Solution Approach 1:
The patent extracts and removes the buffering function from the video transmission path. By eliminating the buffer that causes delay, the system achieves real-time transmission while maintaining stability through alternative mechanisms such as direct peer-to-peer transmission and adaptive encoding that adjusts to network conditions without requiring storage and retrieval operations.
Solution Approach 2:
The patent introduces a control server as an intermediary that manages transmission parameters and coordinates between sender and receiver. This mediator optimizes transmission settings in real-time, enabling stable video delivery without buffering by dynamically adjusting encoding rates, resolution, and transmission protocols based on current network conditions.
2Loss of time
If video is transmitted with ultra-low latency without buffering, then real-time performance is improved, but transmission reliability may worsen
Solution Approach 1:
The patent implements real-time feedback mechanisms where the receiver sends acknowledgment signals and quality metrics back to the sender and control server. This feedback loop enables dynamic adjustment of transmission parameters to maintain reliability without buffering, ensuring packet delivery and adapting to network conditions changes instantaneously.
Solution Approach 2:
The system employs dynamic transmission protocols that adapt in real-time to network conditions. Encoding parameters, transmission rates, and protocol selections are continuously adjusted based on current bandwidth, latency, and packet loss conditions, enabling reliable ultra-low latency transmission by optimizing settings moment-by-moment rather than using fixed buffered approaches.
