Set-Top Box Diagnostic via Cellular Fallback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of Internet Protocol television (IPTV) services face issues with set-top box devices and residential gateways, such as loss of video or audio streams, and VoIP services, due to connectivity problems, which existing diagnostic methods are unable to efficiently resolve.
Innovation Solution
A system and method utilizing a diagnostic server, set-top box device, and network agile device to initiate a diagnostic test, allowing the set-top box device to connect with the diagnostic server via a preferred connection, and if failed, through a cellular network, to diagnose and resolve issues, update software, and dispatch repair tickets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a diagnostic test is initiated through the preferred connection (residential gateway), then diagnostic efficiency and speed are improved, but connectivity reliability deteriorates when the preferred connection fails
Solution Approach 1:
The system dynamically switches between preferred connection and cellular network based on connection status. The diagnostic method first attempts to initiate through the preferred connection (residential gateway), and if that fails, automatically falls back to cellular network, making the connection path adaptive and resilient to failures.
Solution Approach 2:
The cellular network acts as an intermediary backup connection. When the primary preferred connection (residential gateway) fails to establish or maintain connectivity, the cellular network serves as an intermediate alternative that enables the set-top box device to still access the diagnostic server, ensuring continuous diagnostic capability.
2Speed
If the set-top box device continuously monitors network status, then problem detection speed is improved, but energy consumption increases
Solution Approach 1:
Instead of continuous monitoring, the system employs periodic status checks triggered by specific events (connection failures, service interruptions). The set-top box device monitors network status at key moments rather than continuously, reducing energy consumption while maintaining effective problem detection capability.
Solution Approach 2:
The system uses feedback mechanisms where the diagnostic server communicates status information back to the set-top box device. This feedback loop enables problem detection without requiring constant active monitoring, as the device responds to status changes and diagnostic commands from the server rather than continuously polling.
3Measurement precision
If multiple diagnostic tests are performed sequentially, then diagnostic thoroughness is improved, but total diagnostic time increases
Solution Approach 1:
The system performs preliminary diagnostic actions automatically when connection failures are detected. The diagnostic server initiates diagnostic tests and can automatically execute remedial actions (software updates, parameter adjustments) without requiring manual intervention, thereby reducing the time users would otherwise spend on troubleshooting while maintaining comprehensive diagnostic coverage.
Solution Approach 2:
The diagnostic system performs self-service by automatically executing diagnostic tests and remedial actions. The set-top box device and diagnostic server work together to identify and resolve issues without requiring user involvement in each step, reducing the time users would spend manually diagnosing and fixing problems while maintaining thorough diagnostic coverage.

AI summary
A device having a test module configured to connect with a server through a cellular telephone network and a wireless area network. The test module is also configured to initiate, in the server, a diagnostic test of an interactive television network and a media processor. The test module is further configured to receive information indicating problems with the television network and the media processor, and to display the information on a display.
