A streaming data delivery system contrived to curtail the procedure until a session is established between a delivery server and a user terminal includes a delivery device, a server for provisional coupling, format conversion servers, a terminal, and a 3PCC device which implements Third Party Call Control. The 3PCC device obtains format information from the terminal and establishes a session between the terminal and the server for provisional coupling; also obtains data format information from the data delivery device and establishes a session between the delivery device and the server for provisional coupling; further selects a format conversion server, transfers the session between the delivery device and the server for provisional coupling into a session between the delivery device and the selected format conversion server, and transfers the session between the terminal and the server for provisional coupling into a session between the terminal and the selected format conversion server.
