When the end of the setup is determined, the setup processing is ended. As described above, even when the setup is performed from the receiver 1 side and the process is shifted to the setup from the remote controller 2 side, the user does not need to re-enter the setting information necessary for the setup from the beginning. The setting information can be continuously input from the remote controller 2 side. As a result, the user can easily input the predetermined setting information required for the setup.

In the above-described embodiment, a case has been described in which the setup is switched from the remote controller 2 to the setup while the setup is being performed from the receiver 1. However, the setup is performed from the remote controller 2. It is also possible to appropriately apply to a case where the process shifts to the setup from the receiver 1 on the way. Also in this case, the user can continuously input the setting information from the receiver 1 without re-entering the setting information necessary for the setup from the beginning.

In the above embodiment, the communication between the receiver 1 and the remote controller 2 is performed using the IR signal, but the communication signal between the two is arbitrary. For example, RF
(Radio Frequency) signal may be used to perform communication between them.

In the above-described embodiment, the receiver 1 (such as an AV amplifier with a radio broadcast receiving tuner) is described as an example of a device to be controlled, but the device to be controlled is arbitrary. For example, the remote controller 2 may operate an AV device such as a CD or a television monitor as a device to be controlled.
