IPTV Terminal CDN Fallback for Service Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users cannot access video services due to IPTV service system failures such as upgrading, server failure, or network failure, with existing technologies lacking effective solutions to provide continuous service.
Innovation Solution
A method and device that detect IPTV service system accessibility, providing video services through a Content Delivery Network (CDN) subsystem when inaccessible, with threshold-based notifications to users for logging back into the system and limiting emergency video service usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the IPTV service system is used to provide video services, then the service quality and user experience are improved, but the system becomes vulnerable to failures during upgrading, server issues, or network problems
Solution Approach 1:
The patent introduces a CDN subsystem as an intermediary backup system. When the primary IPTV service system becomes inaccessible, the terminal switches to obtain video services through the CDN subsystem, ensuring continuous service availability without direct dependency on the primary system's operational status
Solution Approach 2:
The patent implements beforehand cushioning by pre-configuring the terminal with alternative service acquisition paths. The terminal is capable of switching to the CDN subsystem in advance, so when failures occur during upgrading, server issues, or network problems, service continuity is maintained without interruption
2Reliability
If video services are provided through the CDN subsystem during IPTV system failures, then service continuity is maintained, but unauthorized or excessive usage may occur
Solution Approach 1:
The patent implements feedback mechanisms through threshold-based notifications. The system monitors usage frequency and time duration of CDN subsystem access, and when predefined thresholds are exceeded, it notifies users to log back into the IPTV service system, providing feedback control over emergency service usage
Solution Approach 2:
The patent applies dynamics by making the service access conditions adaptive. The system dynamically adjusts access control based on usage patterns, allowing emergency access within reasonable limits (below thresholds) while requiring re-authentication when limits are approached, creating a flexible rather than rigid access control system

AI summary
Provided are a method and device for providing a video of an Internet Protocol TV or Interactive Personal TV (IPTV) service. The method includes: detecting whether an IPTV service system is accessible for a terminal or not; and when the IPTV system is detected to be inaccessible for the terminal, providing a video for the terminal through a Content Delivery Network (CDN) subsystem. By the technical solution, the technical problems that the user cannot enjoy services such as the video service in case of upgrading, server failure or network failure in the related technology are solved, and live video service can still be provided for the user even though the service of the IPTV service system is inaccessible due to upgrading, server failure or network failure.
