Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If redundant data is repeatedly transmitted in large quantity to reduce packet loss impact, then data transmission reliability is improved, but network resource consumption and processing time increase significantly
Solution Approach 1:
The patent implements dynamic adjustment of the redundancy factor based on real-time transmission status information. The transmitting end monitors network conditions and dynamically modifies the redundancy factor to adapt to changing channel states, ensuring optimal balance between reliability and efficiency without fixed over-provisioning of redundant data.
Solution Approach 2:
The patent introduces a compression factor and redundancy factor that can be dynamically adjusted based on transmission status. By changing these parameters adaptively, the system optimizes the balance between data compression ratio and redundancy level, resolving the contradiction between transmission reliability and network resource consumption.
2Reliability
If redundant data is transmitted in large quantity to compensate for packet loss, then audio quality stability is improved, but transmission latency increases
Solution Approach 1:
The system dynamically adjusts the redundancy factor based on real-time transmission status, avoiding fixed high redundancy that would cause excessive latency. The adaptive mechanism ensures redundancy is added only when necessary, maintaining audio quality stability while minimizing transmission delay.
Solution Approach 2:
The patent performs time domain data compression processing on audio data before channel coding and transmission. This preliminary compression reduces the overall data volume and redundancy requirements, thereby reducing transmission latency while still maintaining sufficient redundancy for packet loss compensation.
3Productivity
If time domain data compression is applied to audio data, then data transmission efficiency is improved, but audio data quality may be compromised
Solution Approach 1:
The patent dynamically adjusts the compression factor based on transmission status information. By adaptively changing the compression level, the system optimizes the balance between compression efficiency and audio quality, ensuring high transmission efficiency without excessive quality degradation.
Solution Approach 2:
The system uses transmission status information as feedback to adjust the compression factor. This feedback mechanism ensures that compression levels are optimized in real-time based on actual network conditions, maintaining audio quality while maximizing transmission efficiency.
