Patent ID: 8782229

Claim:
A transmission management system connecting between a plurality of transmission terminals, at least two of the transmission terminals being connected such that the at least two of the transmission terminals communicate content data to each other, the transmission management system comprising: a status management unit configured to manage status information indicating a communication status between one of the transmission terminals and another one of the transmission terminals, for each of the transmission terminals; and a receiver unit configured to receive a communication initiating request from a first transmission terminal of the transmission terminals to a second transmission terminal of the transmission terminals, wherein in a case where each of first status information of the first transmission terminal managed by the status management unit and second status information of the second transmission terminal managed by the status management unit represents that a corresponding one of the first transmission terminal and the second transmission terminal does not communicate with other transmission terminals when the communication initiating request is received by the receiver unit, a transmission unit transmits the communication initiating request from the first transmission terminal to the second transmission terminal while each of the first status information and the second status information managed by the status management unit is changed from status information indicating that the corresponding one of the first transmission terminal and the second transmission terminal does not communicate with other transmission terminals to status information indicating that the corresponding one of the first transmission terminal and the second transmission terminal communicates with other transmission terminals, and wherein in a case where at least one of the first status information of the first transmission terminal managed by the status management unit and the second status information of the second transmission terminal managed by the status management unit represents that a corresponding one of the first transmission terminal and the second transmission terminal communicates with the other transmission terminals, the transmission unit does not transmit the communication initiating request from the first transmission terminal to the second transmission terminal.
