Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If users share streaming media from mobile devices while moving, then mobility and accessibility are improved, but transmission fluency deteriorates due to communication status limitations and internet speed variations
Solution Approach 1:
The system dynamically adjusts coding parameters based on real-time transmission rate information obtained from the database. The mobile device queries the database using location and time information to get appropriate coding parameters that adapt to current network conditions, enabling flexible adaptation to varying communication status while maintaining transmission fluency
Solution Approach 2:
The database pre-stores transmission rate information for multiple regions and time periods. Before actual media transmission, the system queries the database to obtain anticipated transmission rates for the current location and time, allowing proactive adjustment of coding parameters before transmission issues occur
2Reliability
If coding parameters are adjusted in real-time based on transmission rate, then transmission quality is improved, but system complexity increases due to database management and parameter adjustment mechanisms
Solution Approach 1:
A server-based database acts as an intermediary between network conditions and coding parameter adjustment. The database collects, stores, and manages transmission rate information for multiple regions and time periods, shielding the mobile device from complex data management tasks while providing simplified query interfaces for obtaining appropriate coding parameters
Solution Approach 2:
The system establishes a feedback loop where transmission performance is continuously monitored, location and time information is updated, and coding parameters are adjusted based on database queries. This automated feedback mechanism maintains transmission quality without requiring complex manual intervention

AI summary
A transmission rate determination method for streaming media is disclosed. The transmission rate determination method includes the following steps: collecting a location message, a time message, a communication parameter information and a transmission bit rate of a mobile device; updating a database of streaming throughput according to the location message, the time message, the communication parameter information and the transmission bit rate; wherein the database of streaming throughput includes information regarding a plurality of regions. The information of each of the plurality of regions includes an average transmission rate. The average transmission rate is related to the location message, the time message, the communication parameter information and the transmission bit rate.
