Dynamic Channel Allocation for Mobile TV
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile TV systems inefficiently utilize network resources due to static configuration of channels, which cannot adapt to changing viewer behavior, leading to inefficient distribution of unicast and broadcast services.
Innovation Solution
A method dynamically allocates channels to the most suitable transport technique based on the actual number of viewers, using feedback information to switch between unicast and broadcast, optimizing resource utilization and ensuring seamless viewer experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If channels are statically configured for unicast or broadcast, then network resource allocation is simplified, but network resource utilization efficiency deteriorates
Solution Approach 1:
The patent implements dynamic channel allocation where the transport technique (unicast or broadcast) is automatically selected based on real-time viewer demand. The system monitors the number of viewers for each channel and dynamically switches between unicast and broadcast modes, making the previously static configuration adaptive and responsive to changing conditions.
Solution Approach 2:
The system employs feedback mechanisms to monitor viewer demand and channel performance metrics. Based on this feedback information about the number of viewers and network conditions, the system automatically adjusts channel allocation decisions, creating a closed-loop control system that optimizes resource utilization continuously.
2Device complexity
If manual configuration is used for channel distribution, then system complexity is reduced, but adaptability to changing viewer behavior deteriorates
Solution Approach 1:
The system enables self-service automation where the network automatically monitors viewer demand and makes channel allocation decisions without manual intervention. The automated system evaluates feedback information and dynamically adjusts transport techniques based on actual viewer behavior, eliminating the need for manual reconfiguration while maintaining simplicity for operators.
Solution Approach 2:
The patent transforms the static manual configuration into a dynamic automated system that adapts to changing viewer behavior in real-time. The system automatically switches between unicast and broadcast modes based on monitored viewer counts, providing versatility and adaptability while keeping the operator interface simple.
3Adaptability or versatility
If unicast is used for all channels, then service delivery flexibility is improved, but network congestion increases
Solution Approach 1:
The patent combines unicast and broadcast transport techniques into a unified channel distribution system. For channels with low viewer demand, unicast provides individualized delivery, while for channels with high viewer demand, broadcast is used to serve multiple viewers simultaneously through a single transmission, thereby reducing overall network congestion.
Solution Approach 2:
The system dynamically changes the transport parameter (unicast or broadcast mode) based on viewer demand thresholds. When the number of viewers exceeds a certain threshold, the system switches from unicast to broadcast mode, adjusting the delivery parameter to optimize network resource utilization and reduce congestion.
