Radio Receiver Location Determination via Broadcast Metadata
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing television and radio receivers lack the ability to accurately determine and adapt to their geographical location, leading to incorrect information dissemination during disasters, especially when receiving signals from multiple overlapping broadcast areas, which can result in misinterpretation of local vs. national content.
Innovation Solution
A receiver configured to determine its geographical location using stored geographic transmission information and tuning information, allowing it to prioritize and access local content relevant to its area without the need for GPS or GLONASS, by scanning available frequencies and matching them with stored data to identify the most relevant broadcast zone.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the receiver uses GPS or GLONASS for location determination, then the location accuracy is improved, but the device complexity and cost increase
Solution Approach 1:
The patent uses broadcast signals and geographic transmission information as an intermediary to determine receiver location. Instead of directly using GPS/GLONASS hardware, the system mediates location determination through analyzing received broadcast signals' geographic metadata, thereby achieving location accuracy without adding complex positioning hardware.
Solution Approach 2:
The patent replaces the mechanical/GPS-based location determination system with a signal-processing-based system. By substituting physical positioning hardware with electronic analysis of broadcast signal geographic information, the system achieves location determination without the complexity of GPS receivers.
2Reliability
If the receiver prioritizes local content access, then the reliability of information dissemination is improved, but the adaptability to different geographical areas decreases
Solution Approach 1:
The patent implements dynamic content prioritization based on determined geographical location. The receiver automatically adjusts content priority levels dynamically according to its detected location, ensuring reliable local information delivery while adapting to different geographical areas through automated location-based reconfiguration.
Solution Approach 2:
The patent changes the parameter of content priority based on geographical location parameters. By monitoring location parameters and adjusting content priority parameters accordingly, the system ensures reliable local information dissemination while adapting to different geographical contexts through parameter transformation.
3Measurement precision
If the receiver stores extensive geographic transmission information, then the measurement precision of location determination is improved, but the loss of memory resources increases
Solution Approach 1:
The patent applies partial action by storing only the essential geographic transmission information needed for location determination rather than complete geographic databases. The system stores sufficient information to achieve accurate location determination through signal analysis without occupying excessive memory resources.
Solution Approach 2:
The patent extracts only the necessary geographic transmission information from complete geographic data sets. By extracting and storing only the essential location-determination-related information, the system achieves accurate location measurement while minimizing memory resource consumption.
