RF Receiver Signal Path Switching for Satellite Disruptions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Satellite broadcast signal disruptions due to obstructions cause lower signal receive levels, leading to poor video quality and lengthy troubleshooting processes, frustrating consumers.
Innovation Solution
A method where a receiver server monitors signal receive levels, switches to an alternate signal path if necessary, using out-of-band communications, and automatically switches back when the original signal is restored, with a timer-based approach to manage signal path usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system uses a single original signal path for satellite broadcast reception, then the device complexity is reduced, but the reliability deteriorates when signal disruptions occur due to obstructions
Solution Approach 1:
The system dynamically changes the signal path configuration parameter from a single original path to an alternate path when signal quality degrades. The receiver server monitors signal receive levels and switches the signal path configuration in response to detected disruptions, allowing the system to adapt to changing environmental conditions without permanent complex infrastructure
Solution Approach 2:
The receiver server acts as an intermediary between the signal receivers and the signal paths. It monitors signal quality from multiple receivers, determines when disruptions occur, and coordinates the switching to alternate signal paths, centralizing the complexity management rather than distributing it across all receivers
2Loss of time
If manual troubleshooting is used for signal disruptions, then the device complexity is reduced, but the loss of time increases due to lengthy troubleshooting and restoration processes
Solution Approach 1:
The system performs self-diagnosis and self-restoration by automatically monitoring signal receive levels from multiple receivers, detecting disruptions without human intervention, and switching to alternate signal paths autonomously. The receiver server manages the entire process from detection to restoration, eliminating the need for manual troubleshooting
Solution Approach 2:
The system implements continuous feedback by monitoring signal receive levels from multiple receivers in real-time. When signal quality falls below expected thresholds, the feedback triggers automatic switching to alternate paths. The system continues monitoring to detect when the original signal is restored, creating a closed-loop automatic restoration process
3Productivity
If the system implements automated signal monitoring and alternate path switching, then the productivity is improved by quickly restoring service, but the device complexity increases due to multiple signal paths and coordination infrastructure
Solution Approach 1:
The receiver server performs multiple functions: it acts as a signal monitor, a disruption detector, a path switching controller, and a coordination hub. By consolidating these functions in a single multi-functional component, the system achieves rapid automated restoration without proportionally increasing overall system complexity
Solution Approach 2:
The system prepares alternate signal paths in advance before disruptions occur. The receiver server pre-configures alternate paths and maintains readiness to switch, so when disruptions are detected, the transition can occur immediately without delay for path configuration or setup
Data Source
AI summary
A receiver control is configured to receive signal receive level data from a plurality of signal receivers. The receiver control determines if a signal receive level is lower than expected. In response to determining that the signal receive level is lower than expected, it is determined if an alternate signal is available via an alternate signal path. In response to determining that an alternate signal is available, an instruction is transmitted to one of the plurality of signal receivers with an indication that the alternate signal is to be received via the alternate signal path. The receiver control transmits the alternate signal via the alternate signal path to the one of the plurality of signal receivers experiencing lower than expected signal receive levels in one embodiment. The receiver can resume utilizing an original signal via an original signal path when the signal receive level of the original signal returns to expected levels.
