VOD Terminal Signal Route Detection for Dynamic Resource Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In digital television networks, existing VOD systems require complex static configuration management to ensure that on-demand program streams can reach VOD terminal devices, limiting their mobility and scalability, as the location of the terminal must be fixed and the configuration relation is complex.
Innovation Solution
A method and system for automatically identifying the location of VOD terminal devices and establishing a corresponding relation with IPQAM/QAM resources using a signal route detection method, allowing for dynamic allocation of resources without the need for complex configuration management, enabling terminal roaming and seamless service support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If static configuration scheme is adopted to manage VOD terminal and IPQAM/QAM resource relation, then configuration management can be realized, but terminal location must be fixed and configuration relation becomes very complex
Solution Approach 1:
The VOD terminal automatically detects its own location and identifies available IPQAM/QAM resources without external configuration assistance. The terminal independently performs route detection by sending detection messages and processing detection streams, eliminating the need for complex manual configuration management while maintaining reliable resource allocation
Solution Approach 2:
The system transitions from static configuration to dynamic automatic detection. The terminal's location is no longer fixed but dynamically determined through automatic route detection. The configuration relation adapts automatically based on real-time terminal location and available resources, allowing terminals to roam freely while maintaining service continuity
2Reliability
If static configuration is used to determine signal route, then service delivery can be ensured, but terminal cannot roam and system scale expansion requires reconfiguration
Solution Approach 1:
The system enables dynamic terminal mobility by replacing static configuration with automatic route detection. Terminals can freely move and roam within the service area while the system automatically detects new locations and allocates appropriate IPQAM/QAM resources, maintaining service delivery without requiring reconfiguration for system scale expansion
Solution Approach 2:
The terminal performs automatic route detection by sending detection messages and receiving detection streams to identify available resources. This feedback mechanism continuously updates the terminal's location information and resource allocation, ensuring reliable service delivery while supporting terminal roaming and system scalability
3Reliability
If manual configuration management is implemented for VOD terminals, then resource allocation can be controlled, but configuration work becomes very complex and time-consuming
Solution Approach 1:
The VOD terminal autonomously performs resource allocation by automatically detecting its location and identifying available IPQAM/QAM resources through route detection. This eliminates time-consuming manual configuration work while maintaining controlled and reliable resource allocation, as the terminal independently determines its own resource requirements and assignments

AI summary
The present invention relates to a method, a terminal and a server for allocating a signal route resource in a Video On Demand (VOD) service. The method includes: sending a route detection message to a VOD server; receiving a route resource list replied by the VOD server; receiving a route detection stream according to a signal route resource in the obtained route resource list; judging, according to the received route detection stream, whether the signal route resource corresponding to the received route detection stream is valid; and reporting valid signal route resource information to the VOD server. Through a signal route detection method, a location of a VOD terminal device is automatically identified, so that roaming of the VOD terminal device may be realized, and when a coverage relation of the terminal is changed, the VOD service may be normally supported without any additional processing.
