Abstract: A method of communicating multimedia data includes establishing a first connection between a transmitter unit and an administration server, establishing a second connection between a receiver unit and the administration server, assigning a same unique communication channel to the transmitter unit and the receiver unit by the administration server, establishing a third connection between the transmitter unit and the receiver unit using the same unique communication channel upon the first and second connections being established, and transmitting the multimedia data from the transmitter unit to the receiver unit via the third connection. The transmitter and receiver units respectively have unique identification codes that uniquely identify the units from other units connected to the administration server. The communication channel is assigned using the unique identification codes.
