Receiver Location Discrepancy Detection in Content Delivery Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Content delivery networks face challenges in identifying and managing discrepancies in the location of receivers, leading to inventory management errors, unauthorized usage, and inappropriate pricing due to inconsistencies between subscriber management systems and conditional access systems.
Innovation Solution
A method and system are implemented to analyze indicia of location for receivers, comparing communication paths, signal response characteristics, and inventory states to detect and correct location errors, ensuring accurate inventory management and preventing unauthorized usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple systems (subscriber management system and conditional access system) independently maintain receiver location records, then each system can independently control access and manage its own inventory, but location discrepancies arise between systems leading to inventory management errors and unauthorized usage
Solution Approach 1:
The patent merges the location management functions of the subscriber management system and conditional access system into a unified location determination mechanism. The system combines communication path data from the conditional access system with inventory state data from the subscriber management system to create a comprehensive location verification process, eliminating location discrepancies between the two systems.
Solution Approach 2:
The patent implements a feedback mechanism where the system continuously monitors receiver location through communication path analysis and compares it against expected location based on inventory state. When location discrepancies are detected, the system generates alerts and takes corrective actions such as disabling the receiver, creating a closed-loop control system that maintains location information consistency.
2Measurement precision
If the system implements comprehensive location verification by analyzing communication paths and inventory states, then location accuracy improves and unauthorized usage is prevented, but system complexity and processing requirements increase
Solution Approach 1:
The patent enables the receiver system to self-report its location information through communication path data, and the system automatically verifies this information against inventory state records. The conditional access system autonomously determines location discrepancies and executes corrective actions without requiring manual intervention, reducing the perceived complexity for operators while maintaining high measurement precision.
Solution Approach 2:
The patent performs location verification as a preliminary check before granting or maintaining service access. By analyzing communication paths and comparing them against expected locations in advance, the system prevents unauthorized usage before it occurs, rather than detecting and responding to violations after they happen, which simplifies the overall control logic.

AI summary
A method and system is provided to analyse receiver indicia of location for a set of at least one receivers to determine whether a receiver has an erroneous indicator of location. The embodiment may take further steps to confirm whether or not inappropriate usage has occurred. The method and system includes identifying a first indicia of location for a set of one or more receivers, identifying a second indicia of location for one or more receivers from the set, and determining if the first and second indicia of location are mutually inconsistent. Indicia of location include indicators of receiver location, inventory state, communication path and definition on systems. The method and system may optionally include action to report or correct the location error.
