TRANSMISSION MANAGEMENT SYSTEM, TRANSMISSION SYSTEM, AND PROGRAM FOR TRANSMISSION MANAGEMENT SYSTEM

摘要

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