Set-Top Box Location Detection via Wireless Environment Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need to detect unauthorized relocation of television receiver devices from their registered residential locations to commercial settings to prevent unfair exploitation of lower pricing for premium content, which can violate laws and unfairly prejudice establishments paying commercial rates.
Innovation Solution
A television set top box or receiver device gathers and stores wireless network information, comparing it over time to detect changes in location, and may report this change to a security service, potentially disabling access to premium content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a television receiver device is registered to a residential address to obtain premium content at residential rates, then the subscriber pays lower fees, but the device can be physically relocated to commercial establishments for unauthorized viewing by large groups
Solution Approach 1:
The system continuously monitors wireless environment parameters (Wi-Fi networks, Bluetooth devices, cellular signals) and compares them against stored baseline data from the registered location. When deviations exceed thresholds, the system triggers location change detection and prevents premium content access, creating a closed-loop feedback mechanism that dynamically authenticates location
Solution Approach 2:
The patent introduces wireless environment parameters as an intermediary layer between the receiver device and the premium content delivery system. These environmental characteristics (Wi-Fi SSIDs, Bluetooth MAC addresses, cellular tower IDs) serve as indirect indicators of physical location, allowing the system to verify location without direct GPS or manual input
2Measurement precision
If the system monitors wireless network information continuously to detect location changes, then location detection reliability improves, but device complexity and energy consumption increase
Solution Approach 1:
The system performs partial monitoring by selectively measuring specific wireless parameters (Wi-Fi SSIDs, Bluetooth device MAC addresses, cellular tower IDs) rather than all possible environmental signals. Comparison is performed against a stored baseline with tolerance thresholds, allowing detection of significant location changes while ignoring minor fluctuations, thus reducing processing complexity
Solution Approach 2:
The monitoring system is divided into separate functional modules: wireless signal acquisition (gatherer component), data processing and comparison (analyzer component), and authentication decision (controller component). Each module handles specific tasks independently, reducing overall system complexity and enabling targeted optimization of each segment
3Object-affected harmful factors
If the system disables premium content access when location change is detected, then prevention of unauthorized viewing improves, but legitimate residential users may experience service interruption
Solution Approach 1:
The system performs preliminary verification by comparing current wireless environment data against the stored baseline before allowing premium content access. This preemptive check prevents unauthorized viewing before it occurs, rather than reacting after detection. The baseline is established during initial device setup at the registered location
Solution Approach 2:
The system dynamically adjusts the strictness of location verification based on the confidence level of the match between current and baseline environmental parameters. When parameters closely match, access is granted smoothly; when significant deviations are detected, access is restricted. This dynamic response prevents false positives while maintaining security
Data Source
AI summary
A television set top box (STB) or similar receiver device uses information obtained from a wireless interface to automatically detect when the device has been moved to a different location. The device may initially obtain a list of wi-fi zones or in-range wireless devices that can be quantified or stored for later comparison. If the device later finds that the original zones/devices are no longer present or that substantial numbers of new zones/devices are present, then the device can recognize that it has been moved to a new location. The device may respond to the detected location change by disabling premium content, by reporting back to a security service, by simply recording the change in location, or by taking other actions as appropriate.
