PROBLEM TO BE SOLVED: To prevent specific processing accompanied by the restart of a karaoke device from being executed in response to an operation instruction from a remote control terminal when the operation of the karaoke device should not be interrupted.SOLUTION: A remote control terminal transmits the execution request of normal processing to a karaoke device by using radio LAN communication (S10). When receiving the execution request of the normal processing from the remote control terminal by using the radio LAN communication, the karaoke device executes the normal processing corresponding to the received execution request (S12). On the other hand, when transmitting the execution request for allowing the karaoke device to execute specific processing accompanied by the restart of the karaoke device to the karaoke device, the remote control terminal transmits the execution request of the specific processing by using both the radio LAN communication and infrared communication (S20, S22). Under a condition where the karaoke device receives the execution request of the specific processing by using both the radio LAN communication and the infrared communication from the remote control terminal, the karaoke device executes the specific processing corresponding to the received execution request (S24). |
