Solution Overview
Problem
Satellite-based media content processors face disruptions due to weather events or satellite signal blockages, leading to service outages and quality issues, which existing systems struggle to address effectively.
Innovation Solution
An adaptive backup system that monitors satellite signal quality and switches to an Internet-based media content delivery when the signal falls below a threshold, using available network connections such as Internet Service Providers or cellular networks, ensuring continuous media content provision and minimizing 'flip-flopping' between sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If satellite signal is used for media content delivery, then service coverage and bandwidth capacity are improved, but service reliability deteriorates due to weather events and signal blockages
Solution Approach 1:
The patent combines satellite delivery and Internet-based delivery into a unified hybrid system. The media processor receives content from both satellite and Internet sources simultaneously, enabling seamless switching and content aggregation between the two delivery mechanisms to maintain service reliability while preserving bandwidth capacity.
Solution Approach 2:
The system dynamically changes the delivery parameter by switching between satellite-based delivery and Internet-based delivery based on signal quality conditions. When satellite signal quality falls below a threshold, the system transitions to Internet-based delivery, and vice versa, optimizing both reliability and bandwidth utilization.
2Reliability
If backup system switches to Internet connection when satellite signal quality drops, then service continuity is improved, but system complexity increases
Solution Approach 1:
The media processor performs self-service by autonomously monitoring satellite signal quality and automatically switching between satellite and Internet delivery modes without requiring external intervention. The system self-manages the complexity of dual-source integration through built-in quality assessment and automatic route selection.
Solution Approach 2:
The system implements feedback control by continuously monitoring satellite signal quality and using this information to dynamically adjust the content delivery source. The quality metric feeds back to the switching logic, creating a closed-loop system that maintains service continuity while managing complexity through adaptive decision-making.
3Adaptability or versatility
If frequent switching between satellite and Internet sources occurs, then service adaptability is improved, but service stability deteriorates due to flip-flopping
Solution Approach 1:
The system takes preliminary action by establishing a quality threshold before switching occurs. The threshold is set in advance to prevent premature or unnecessary switching, ensuring that only significant quality degradation triggers a source change. This preliminary condition stabilizes the system by filtering out minor fluctuations.
Solution Approach 2:
The switching mechanism is made dynamic with hysteresis characteristics. The system uses different threshold levels for switching from satellite to Internet versus switching back, creating a dynamic buffer zone that prevents oscillation. This dynamic approach maintains adaptability while ensuring service stability by avoiding flip-flopping between sources.
