Streaming Server Dynamic Bit Rate Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current streaming servers lack the ability to inform clients about time-varying data flow rates and the causes of these variations, leading to potential data loss and quality issues due to unknown discrepancies between specified and actual data transmission rates.
Innovation Solution
A data-streaming server that determines and communicates permissible bit rates to clients based on transmission medium and equipment conditions, using feedback information to adjust encoding rates and notify clients of changes, ensuring data integrity and quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the streaming server transmits data at a high specified flow rate, then the data transmission speed is improved, but data loss occurs due to transmission medium limitations and equipment conditions
Solution Approach 1:
The patent implements dynamic flow rate adjustment by continuously monitoring transmission medium conditions and equipment status, then adapting the encoding rate in real-time to match current capabilities, preventing data loss while maximizing transmission speed
Solution Approach 2:
The system employs feedback mechanisms where the server receives status information from clients and transmission medium, uses this feedback to determine actual permissible flow rate, and adjusts encoding accordingly to maintain data integrity
2Productivity
If the streaming server uses data compression techniques to increase flow rate, then the data transmission efficiency is improved, but the actual received flow rate becomes fluctuating and differs from specified flow rate
Solution Approach 1:
The patent implements feedback loops where the server monitors actual encoding rates produced by compression techniques, compares them against specified rates, and adjusts compression parameters to maintain accuracy while preserving transmission efficiency
Solution Approach 2:
The system replaces fixed mechanical flow rate specifications with adaptive electronic control that dynamically adjusts encoding rates based on real-time conditions, substituting rigid predetermined values with flexible condition-based determination
3Reliability
If the streaming server adapts signals to match transmission limitations, then data integrity is preserved, but the client has no means of determining the actual flow rate or cause of discrepancies
Solution Approach 1:
The patent introduces notification messages as intermediary information carriers that convey flow rate determination reasons from server to client, bridging the information gap while maintaining signal integrity adaptation
4Reliability
If the streaming server monitors and adjusts encoding rates in real-time, then data quality is maintained, but the system complexity increases due to feedback processing and notification mechanisms
Solution Approach 1:
The patent implements multi-functional components where the flow controller simultaneously performs monitoring, determination, adjustment, and notification functions, reducing overall system complexity through functional consolidation
