Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If service providers deploy error identification devices and implement comprehensive error tracking systems to accurately diagnose video tiling issues, then diagnostic accuracy and troubleshooting efficiency improve, but device complexity and implementation costs increase
Solution Approach 1:
The patent introduces an error identification device as an intermediary component deployed within the multicast network. This device collects state information signals from routers, tracks packet data and errors across links and paths, and generates logical representations of the multicast tree. By placing this intermediary error tracking system within the network infrastructure, the patent enables accurate error detection without requiring complex modifications to existing video receivers or transmission sources, thus improving diagnostic accuracy while managing system complexity.
Solution Approach 2:
The patent implements a feedback mechanism where the error identification device continuously monitors the multicast network, collects error data from routers and links, and provides actionable information back to service technicians. The device generates logical representations that feed back into the troubleshooting process, enabling technicians to accurately identify error sources. This feedback loop transforms raw error data into diagnostic insights, improving measurement precision through systematic information collection and analysis.
2Loss of time
If service providers implement comprehensive error tracking across all network components to identify the root cause of video tiling, then troubleshooting time is reduced, but the complexity of error identification and data analysis increases
Solution Approach 1:
The patent segments the error detection and analysis function into a dedicated error identification device separate from the video transmission and reception components. This device independently collects state information from multiple routers, tracks errors across different links and paths, and generates separate logical representations for each multicast tree. By segmenting the error tracking function, the patent simplifies the complexity of error identification while enabling comprehensive monitoring, thus reducing troubleshooting time without overwhelming service technicians with integrated system complexity.
Solution Approach 2:
The patent creates logical representations (copies) of the multicast tree structure and error data that mirror the actual network topology and error conditions. These logical representations are generated by the error identification device and provide service technicians with simplified views of the network state without requiring direct analysis of the complex physical network infrastructure. By working with these copied logical models, technicians can efficiently identify error sources while avoiding the complexity of directly analyzing the full network system.
3Reliability
If video receivers are replaced to resolve video tiling issues without accurate error source identification, then customer service is maintained, but unnecessary equipment replacement and costs occur
Solution Approach 1:
The patent enables preliminary error identification and diagnosis before any equipment replacement is considered. The error identification device continuously monitors the multicast network and can identify the precise location and source of errors causing video tiling. This preliminary error detection allows service providers to determine whether the issue lies with transmission sources, routers, links, or receivers before taking action. By performing this preliminary diagnostic action, the patent prevents unnecessary receiver replacements and directs repairs to the actual error source, reducing equipment waste while maintaining service reliability.
Data Source
AI summary
A method for detecting errors on an audio/video (A/V) data stream in a data service network includes providing multicast components operably coupled to each other via respective links for transmitting the A/V data stream to a user and for defining at least one multicast tree. The method further includes generating a state information signal indicative of a number of errors on the A/V data stream for at least one of the links and at least one of the plurality of multicast components. The method further includes determining the cumulative number of errors on the A/V data stream that are indicative of the number of errors for the at least one of the links and the at least one of the plurality of multicast components in the multicast tree in response to the state information signal.
