SYSTEM, AND METHOD OF CONTROLLING DATA TRANSMISSION, AND RECORDING MEDIUM

摘要

A transmission management system (50), when a request for starting communication with a second transmission terminal is received from a first transmission terminal (10), obtains first service contents information associated with first service identification information for identifying a service to be provided to the first transmission terminal (10), and causes a relay device (30) to transmit content data that matches the first service contents information to the second transmission terminal (10) in response to receiving content data at the relay device (30) from the first transmission terminal (10).The service contents information indicates quality of data to be transmitted between first and second transmission terminal.
