Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional wireless content delivery systems face challenges in providing a constant stream of data to users, as signals from primary sources can be interrupted, and there is a lack of feedback mechanisms to adapt to changing network conditions, leading to disruptions in mobile television and other multimedia services.
Innovation Solution
A system that establishes dual data links between a mobile device and two sources, allowing the device to receive and transmit data streams, and uses transmission statistics to switch between sources based on signal quality, ensuring seamless content delivery and providing additional data streams or consumer purchasing opportunities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single data link is used for mobile TV delivery, then the system complexity is reduced, but the reliability of continuous content delivery deteriorates due to signal interruptions
Solution Approach 1:
The patent applies local quality by evaluating and selecting data streams based on their individual signal qualities (SNR, bit error rate) at the mobile device location. The system monitors the quality of each data link locally and switches between them based on real-time conditions, ensuring reliable delivery without requiring complex centralized control.
Solution Approach 2:
The patent implements feedback mechanisms where the mobile device continuously monitors transmission statistics and signal quality from multiple data streams, feeds this information back to the controller, which then adjusts the active data link accordingly. This closed-loop feedback enables automatic adaptation to changing network conditions and maintains delivery reliability.
2Adaptability or versatility
If multiple data streams are received and monitored, then the adaptability to network conditions improves, but the device processing complexity increases
Solution Approach 1:
The patent applies partial action by selectively monitoring and processing only the essential transmission statistics (SNR, bit error rate) from multiple data streams rather than analyzing every possible parameter. This approach provides sufficient adaptability to network conditions while keeping the processing burden manageable for mobile devices.
Solution Approach 2:
The system performs preliminary actions by pre-establishing multiple data links and pre-configuring the mobile device with the capability to monitor and switch between them. When network conditions change, the device can quickly switch to an alternative pre-configured link without requiring complex real-time analysis or reconfiguration.
3Stability of the object's composition
If real-time switching between data streams is implemented, then the service continuity improves, but the measurement and detection difficulty increases
Solution Approach 1:
The patent applies self-service by having the mobile device autonomously monitor its own reception quality and make switching decisions without requiring complex external measurement systems. The device uses built-in receivers and processors to measure SNR and bit error rates, then automatically selects the best data stream, eliminating the need for sophisticated external detection and measurement infrastructure.
