Audio Video Server Dynamic Parameter Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current audio and video transmission systems lack flexibility in adjusting parameters, leading to increased operating costs and poor network performance, especially when direct channel connections fail and require relay connections.
Innovation Solution
An audio and video server system that receives and analyzes information from terminals to adjust transmission parameters based on terminal types, connection request types, and network conditions, dynamically optimizing parameters such as code rate, frame rate, and FEC codes for improved quality and efficiency.

Engineering Contradiction Analysis
1Manufacturing precision
If audio and video transmission parameters are adjusted at client terminals, then transmission quality can be optimized, but control flexibility deteriorates and operating costs increase due to requiring new application versions
Solution Approach 1:
The patent introduces a server as an intermediary between multiple client terminals to centrally manage and adjust audio and video transmission parameters. The server receives transmission data from clients, analyzes network conditions, and dynamically adjusts parameters such as code rate, frame rate, and resolution. This centralized approach eliminates the need to modify client terminal control logic, thereby maintaining control flexibility while achieving optimized transmission quality through adaptive parameter adjustment based on real-time network conditions.
2Reliability
If a relay channel connection is used when direct connection fails, then connection reliability is improved, but transmission efficiency deteriorates due to additional routing hops
Solution Approach 1:
The patent dynamically adjusts transmission parameters based on the connection type (direct or relay). When relay channel connection is used, the server modifies parameters such as reducing frame rate, lowering resolution, or decreasing code rate to compensate for the additional routing hop. This adaptive parameter adjustment maintains acceptable transmission quality and efficiency even when reliability improvements require suboptimal transmission paths.
