Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional television conference systems face increased load and limited relay device selection when multiple communication start requests occur simultaneously, leading to reduced flexibility and efficiency in managing connections between terminals and relay devices.
Innovation Solution
A transmission management system that includes a relay device selection mechanism, utilizing a relay device selection device to choose an optimal relay device based on priority and domain information, allowing for communication control across multiple management systems, thereby increasing the degree of freedom in relay device selection and improving load management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single transmission management system controls all communication start requests, then the system can manage connections centrally, but the load on the transmission management system significantly increases when multiple communication requests occur simultaneously
Solution Approach 1:
The patent divides the transmission management system into multiple independent transmission management systems, each capable of handling communication requests. Instead of one centralized system managing all connections, the functionality is segmented across multiple systems that can independently select and manage relay devices, thereby distributing the load while maintaining centralized control capabilities through coordination protocols
2Productivity
If multiple transmission management systems are provided to disperse loads, then the load on individual systems is reduced, but the degree of freedom of selection of relay devices is limited to only those controlled by the own transmission management system
Solution Approach 1:
The patent implements a relay device selection mechanism that enables transmission management systems to select from relay devices across multiple management domains. The selection device can identify and choose relay devices controlled by different transmission management systems, making the system universal in its ability to access relay devices beyond its own controlled set, thus maintaining adaptability while benefiting from load distribution
3Device complexity
If relay device selection is limited to devices controlled by the own transmission management system, then control is simplified, but the flexibility and efficiency of communication management is reduced
Solution Approach 1:
The patent introduces a relay device selection device as an intermediary component that mediates between the transmission management system and relay devices controlled by other management systems. This intermediary enables extended relay device selection without requiring the transmission management system to directly control all relay devices, thus maintaining control simplicity while enhancing communication management flexibility through the mediating selection mechanism

AI summary
A transmission/reception unit 51 of a management system 50 receives a relay device ID transmitted by a selection device 80. Also, the transmission/reception unit 51 transmits communication control request information to another management system 50 based on the relay device ID. Consequently, a relay device 30 to be used to relay content data to be transmitted/received among terminals 10 can be selected from relay devices 30 that the another management system 50 can control.
