Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If streaming media transmission is implemented with real-time segment-by-segment transmission, then users can obtain media data in real time without downloading complete files, but transmission efficiency and stability are reduced due to high device performance and network condition requirements
Solution Approach 1:
The patent segments streaming media objects into multiple categories based on quality and priority levels. Each segment is transmitted independently with its own quality parameters, allowing the system to transmit critical segments with high priority while reducing or skipping less important segments when network conditions degrade, thus maintaining both efficiency and stability
Solution Approach 2:
The patent implements dynamic adaptation by adjusting transmission parameters based on real-time network conditions and device performance. The system dynamically selects which media segments to transmit and at what quality level, allowing the transmission to adapt between high efficiency modes (when network is good) and high stability modes (when network degrades), resolving the contradiction between productivity and reliability
2Manufacturing precision
If high quality streaming media is transmitted to ensure good viewing experience, then media quality is improved, but transmission stability deteriorates under degraded network conditions
Solution Approach 1:
The patent applies local quality by differentiating media objects into multiple quality levels (e.g., high quality, medium quality, low quality segments). Instead of transmitting all media at uniform high quality, the system transmits high quality only to critical segments while using lower quality for less important segments, maintaining overall media quality where possible while ensuring stability through selective quality reduction
Solution Approach 2:
The patent changes transmission parameters such as bit rate, resolution, and segment selection based on network conditions. When network conditions are good, high quality parameters are used; when conditions degrade, the system switches to lower quality parameters or prioritizes transmission of critical segments, thus maintaining transmission stability while preserving media quality when conditions permit
3Reliability
If streaming media transmission adapts to device and network conditions to improve stability, then transmission reliability is improved, but transmission efficiency deteriorates
Solution Approach 1:
The patent implements feedback mechanisms that continuously monitor network conditions and device performance, then adjust transmission strategies accordingly. The system receives feedback about network status and automatically modifies which segments are transmitted and at what quality level, enabling the system to achieve high stability when network conditions are poor while maintaining high efficiency when conditions are good, thus resolving the contradiction between reliability and productivity

AI summary
A streaming media transmission method and apparatus are provided. The method may include: parsing streaming media transmission signaling to obtain a ranking relationship descriptor of each streaming media object.) The method may further include forming a ranking relationship set with at least two streaming media objects having the same ranking identifier field. The method may further include ranking the at least two streaming media objects in the ranking relationship set according to the ranking information field to obtain a streaming media object sequence. The method may further include selecting a to-be-received target streaming media object from the streaming media object sequence, and transmitting a streaming media transmission request for the target streaming media object, the streaming media transmission request being used for requesting to acquire the target streaming media object.
