Multipoint Video Distribution System Importance-Based Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multipoint video distribution systems switch between primary and backup systems based solely on distribution availability, leading to temporary interruptions at important destinations when unimportant destinations experience issues, causing significant disruptions, especially in live video streaming.
Innovation Solution
Implementing a multipoint distribution system with an importance level database to determine whether to switch from the primary to the backup system only when an important distribution destination is affected, allowing continued distribution to important destinations while restoring service to unimportant ones.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If automatic switching between primary and backup distribution systems is implemented based on distribution availability, then system reliability is improved, but important distribution destinations experience temporary interruptions when unimportant destinations have issues
Solution Approach 1:
The patent applies local quality by assigning different importance levels to different distribution destinations. The management device determines switching based on the importance level of the affected destination rather than treating all destinations uniformly. This allows the system to prioritize critical destinations and avoid switching when only unimportant destinations are affected, thereby preventing harmful interruptions at important locations while maintaining overall system reliability.
2Ease of repair
If system switching is triggered by any distribution failure, then service restoration is achieved, but critical destinations suffer interruptions to restore unimportant destinations
Solution Approach 1:
The patent implements dynamics by making the switching decision adaptive based on real-time conditions. The management device dynamically evaluates the importance level of affected distribution destinations and adjusts the switching behavior accordingly. This dynamic approach allows the system to maintain flexibility in service restoration while minimizing unnecessary interruptions at critical destinations, optimizing the balance between repair efficiency and service continuity.
3Device complexity
If uniform switching policy is applied to all distribution destinations, then system simplicity is maintained, but important destinations experience unnecessary disruptions
Solution Approach 1:
The patent applies preliminary action by pre-establishing importance levels for different distribution destinations before failures occur. The management device stores and retrieves this importance information to guide switching decisions. This preliminary classification enables the system to implement differentiated switching policies without requiring complex real-time analysis during failures, maintaining operational simplicity while ensuring service continuity at important destinations.
Data Source
AI summary
An object is to provide a multipoint distribution system, a distribution method, a management apparatus, and a program which determine whether or not to switch between a current-use system and a backup system in consideration of the importance levels of distribution destinations. The multipoint distribution system according to the present invention includes a distribution destination system importance level database that stores the importance levels of distribution destinations. When a distribution destination not able to communicate with a current-use video distribution system is detected, the multipoint distribution system performs switching from the current-use video distribution system to a backup video distribution system only upon determining that the distribution destination is important by referring to the distribution destination system importance level database.
