In addition, it is possible to display how the remote control signal for controlling the remote control of the other device is a remote control signal for controlling the other device, and to determine how the remote control signal for controlling the other device is. Since there is no need to remember, it is possible to provide a remote control system with extremely high operability. It will be very useful.

In the embodiment of the present invention, infrared rays are used as remote control signals. However, other means, such as various kinds of means such as electromagnetic waves having lower frequency than infrared rays and ultrasonic waves, can be applied. Further, the present invention can be applied to a wired remote control system such as CI. Although the embodiment of the present invention uses an air conditioner as another device, the present invention can be applied to other devices such as a certification device.
