ABSTRACT:
According to one embodiment, an audio-visual apparatus that has received operation information transmitted using infrared receives a response signal via a radio frequency from a remote controller set to a combination mode transmitting operation information using both infrared and a radio frequency. The remote controller that has received the response signal transmitted from the AV apparatus within a predetermined time is automatically set to a temporary infrared only mode transmitting operation information using infrared only in place of the combination mode.
