Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If streaming distribution is performed with encoding data and data distribution, then service accessibility and network utilization are improved, but image visibility and quality are impaired
Solution Approach 1:
The system performs preliminary evaluation of image quality by decoding the encoded data before actual distribution. This advance assessment allows the generation of guidance information that pre-adjusts encoding parameters, ensuring that image quality issues are addressed before they affect the distributed content.
Solution Approach 2:
The system implements a feedback mechanism where evaluation results from decoding processed data are used to generate guidance information. This guidance information is then fed back to adjust the encoding process, creating a closed-loop system that continuously improves image quality based on actual decoding performance.
2Productivity
If encoding parameters are optimized for data distribution, then transmission efficiency is improved, but decoded image quality deteriorates
Solution Approach 1:
The system dynamically adjusts encoding parameters based on real-time evaluation results. Instead of using fixed encoding settings, the system modifies parameters such as bit rate, resolution, and compression level according to the specific characteristics of the content being encoded, optimizing both transmission efficiency and decoded quality for each scenario.
Solution Approach 2:
The system changes multiple encoding parameters simultaneously based on evaluation guidance. This includes adjusting compression ratios, color depth, frame rate, and other technical parameters to achieve the optimal balance between transmission efficiency and image quality, rather than relying on a single parameter adjustment.
