PROBLEM TO BE SOLVED: To automatically log out following end of the use of a karaoke device. SOLUTION: By providing the terminal identification information matching the user identification information which the user inputs in advance to the user's terminal unit 4 (c-g), the karaoke device 2 recognizes only the terminal unit 4 accessing with the terminal identification information matching the user identification information as the user's terminal unit 4 and then becomes to a state for monitoring the communication with it. When finding the communication end with the terminal unit (n) after starting the monitoring of the communication with the terminal unit 4, it releases the session set up based on the user identification information matching the terminal identification information for accessing the terminal unit 4 (p). Thus, the users log-out with the management server 3 through the karaoke device 2 can be made automatically without requiring the manipulation by the user. COPYRIGHT: (C)2009,JPO&INPIT
