Detecting Unauthorized Set-Top Box Use via Broadcast Fingerprint
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Content providers face difficulties in detecting unauthorized use of devices programmed for private residence service being used in public places, as this misuse is hard to detect without physical inspection.
Innovation Solution
An operator device receives a fingerprint from a user equipment device, which is a unique identifier, and compares it with user account information to determine if the device is being used unauthorized, displaying or transmitting the fingerprint to detect misuse.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If physical inspection of each suspected consumer device is performed to detect unauthorized use, then detection accuracy is improved, but device complexity and operational difficulty increase
Solution Approach 1:
The patent extracts the device identifier information from the physical device itself and places it in the broadcast signal. The set-top box extracts and compares this identifier with authorized device identifiers, eliminating the need for physical inspection while maintaining detection accuracy.
Solution Approach 2:
The patent replaces the mechanical/physical inspection process with an electronic signal-based system. Device identifiers are transmitted through broadcast signals and processed electronically, substituting manual physical inspection with automated electronic detection.
2Device complexity
If no detection system is implemented, then device complexity remains low, but unauthorized use cannot be detected
Solution Approach 1:
The system implements feedback by continuously monitoring device identifiers in broadcast signals and comparing them against authorized device lists. This closed-loop feedback mechanism enables automatic detection and reporting of unauthorized devices without requiring complex manual intervention.
Solution Approach 2:
The set-top box automatically performs detection, comparison, and identification of unauthorized devices without requiring external inspection. The system serves itself by autonomously monitoring and reporting misuse, reducing the need for external detection mechanisms.

AI summary
Systems and methods for detecting unauthorized use of a user equipment device are provided. An instruction is transmitted, using communications circuitry of a handheld device, to the user equipment device directing the user equipment device to display a unique identifier associated with the user equipment simultaneously with media content. An image of the media content and unique identifier simultaneously displayed on a display screen coupled to the user equipment device is captured using camera equipment of the handheld device. The image is automatically processed with the handheld device to extract the unique identifier from the image. The extracted unique identifier is cross-referenced, using the handheld device, with user account information associated with the user equipment device to determine whether use of the user equipment device is unauthorized.
