Auditing Receiver for Digital Media Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cable TV receivers are unreliable when continuously playing specific channels, leading to high maintenance costs and downtime due to frequent channel lineup changes, which necessitates a reliable system for automatic correction and monitoring.
Innovation Solution
A system that detects and corrects cable TV receiver connection parameter changes by using an auditing receiver to retrieve and verify connection parameters from a virtual channel map, allowing for automatic reconnection of active receivers to ensure continuous monitoring, or by embedding monitoring software on receivers or servers to check for lineup changes and initiate reconnection as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cable TV receivers are used to continuously play specific channels for monitoring, then content monitoring capability is provided, but receiver reliability deteriorates due to frequent channel lineup changes requiring manual re-tuning
Solution Approach 1:
The system enables receivers to automatically detect and correct their own connection parameter changes by comparing against a virtual channel map, eliminating the need for manual re-tuning by operators. The monitoring system autonomously identifies when a receiver has drifted from the correct channel and initiates correction without human intervention.
Solution Approach 2:
The system implements continuous monitoring of receiver connection parameters and compares them against the authoritative virtual channel map. When discrepancies are detected, the system provides feedback to automatically correct the receiver's tuning parameters, creating a closed-loop control system that maintains reliable operation despite provider lineup changes.
2Manufacturing precision
If manual monitoring and correction of cable TV receivers is performed, then connection accuracy can be maintained, but maintenance costs and downtime increase due to frequent interventions
Solution Approach 1:
The system proactively monitors receiver connection parameters and detects drift before it causes complete monitoring failure. By identifying and correcting connection parameter changes in advance, the system prevents downtime and maintains continuous monitoring operation without requiring reactive maintenance interventions.
Solution Approach 2:
The automated monitoring system performs self-diagnosis and self-correction of receiver connection parameters, eliminating the need for external maintenance personnel to manually intervene. This autonomous operation reduces both maintenance costs and downtime by handling corrections immediately when issues are detected.
3Adaptability or versatility
If cable providers change channel lineups to improve service, then service quality is enhanced, but receiver operation stability deteriorates requiring frequent re-tuning
Solution Approach 1:
The virtual channel map serves as an intermediary authority between the cable provider's lineup changes and the receivers. Instead of receivers directly responding to provider changes (which causes instability), the monitoring system uses the virtual channel map as a reference to mediate and coordinate the adaptation process, ensuring receivers transition smoothly to new lineups while maintaining operational stability.
Solution Approach 2:
The system dynamically adapts receiver connection parameters in response to provider lineup changes by continuously comparing against the updated virtual channel map. This dynamic adjustment process allows the system to maintain stability through controlled, automated changes rather than experiencing disruptive manual re-tuning, accommodating provider adaptability while preserving receiver operation stability.
Data Source
AI summary
The invention provides a method for monitoring a digital media receiver (including receivers for television or other type of digital media) to determine whether it is necessary for a receiver to re-connect in order to continue receiving a predetermined channel or stream. This invention is useful in digital media monitoring systems and in situations with many receivers connected to the same signal source and predetermined channels defined to be output by each receiver. One embodiment of the invention uses an auditing receiver that constantly scans the upstream channel-map, guide data, service information or system information to determine if the connection parameters required for receiving each predetermined stream have changed. Some examples of connection parameters include packet identifiers (PIDs), radio frequency (RF) channel and uniform resource locator (URL), depending on the type of broadcast and stream. When the auditing receiver gathers the latest connection parameters, a monitoring system compares the recently checked connection parameters to the connection parameters currently in use on each other receiver to determine if each receiver needs to be re-connected to continue receiving the predetermined stream defined for that receiver.
