Abstract

PURPOSE:To display a state of a relevant device not handling a video image after its control by sending a signal representing the device from the relevant device and displaying the signal on a display section of the 2-way remote commander. CONSTITUTION:Upon the receipt of a radio wave at a reception section 10 of a relevant device from a 2-way remote commander, a decode section 11 extracts code data and store the data to a temporary memory 12. After a drive section 15 and an electronic tuner 16 are controlled based on the code data, a transmission section 14 sends prescribed code data. Upon the receipt of the radio wave by a reception section 5 of the 2-way remote commander, a decode section 6 extracts the code data and stores the data to a temporary memory 3. Then the state of the relevant device after control is displayed on a display section 7 based on the code data. Thus, even when the relevant device does not handle a video image like a PCM audio broadcast receiver, the state after the control of the relevant device or the like is displayed surely.

[0005]

Since the bidirectional remote controller transmits the control signal to the corresponding device, the corresponding device receives and decodes the control signal to obtain the code data, and the device based on the code data is constituted. Control is performed, and then the device transmits a signal indicating the state. Alternatively, the device transmits a signal indicating the state in response to the inquiry signal of the device state. The bidirectional remote controller receives and decodes a signal representing the state transmitted by the device, obtains code data, and displays the state of the device after control based on the code data.
