Description of the Related Art In an audio (or stereo) system, a player that reproduces voice (music) data recorded on a disc such as a DVD (Digital Versatile Disk) or a CD (compact disc) and reproduction data output from this player. Is converted into an analog signal by a digital-analog converter and is amplified, and is configured by an amplifier (amplifying device) for driving a speaker or the like, a receiver, or the like. There are various combinations of devices that make up these audio systems, and the manufacturers of the devices are not necessarily the same.

In such an audio system, there is provided a selection / adjustment device for performing various selections or adjustments such as power on / off, reproduction start / interruption / stop, music selection, amplification (output amplitude) and sound quality. ing. The user can manually select / adjust each of these selection / adjustment devices with a finger or the like, but can also select / adjust by a remote control device using radio waves or infrared rays. When the remote control device is used, the user can select / adjust from a position distant from the electronic device within a certain range, which is convenient because the user can operate the device without standing up. Further, the remote control device is a device SE of the system configured as described above.
TUP is also required.

The remote control device of the receiver has an IR for making settings for operating equipment connected to the receiver.
There is a SETUP function. In this IR SETUP, the source device is set to be operable by the receiver remote controller. In addition, this receiver remote control has multiple types of remote control codes (regardless of in-house or other manufacturers) internal ROM
(Read-only memory), it is searched whether the remote control code received from the remote control of the source device exists in the internal ROM, and if there is, the operation of the source device is read by the internal R.
Enable operation within the range recorded in OM. IR S
The ETUP function is set by inputting a code number or operating an LCD (liquid crystal display) screen. There are the following two methods for inputting the code number. First, input by referring to the code number of each source device described in the instruction manual (manual) of the receiver. Secondly, when the remote control device of the receiver is provided with an LCD display screen, the display screen is set to IR SETUP mode,
Select the selector, type, and manufacturer of the device you want to register.
As a result, some code numbers are displayed on the LCD, and the user selects and inputs the code number desired from the display.

When either of the above-mentioned input methods is selected and input, the power code of the device corresponding to the code is output. If the code number and the device match, the device turns on and you know that the settings are complete. If they do not match, enter another code and perform the operation until they match. Such an operation is shown in FIG. 6 and FIG.
Will be described below.

In the flowchart of FIG. 6, the instruction manual is referred to (step A1). Next, the code number is input to the remote controller (step A2). As a result, the power code is output from the remote controller (step A3).
Next, it is determined whether or not the power of the source device, that is, the device connected to the receiver is turned on (step A4). If the power is turned on (step A4: YES), SETU
The P is ended (step A5). On the other hand, if the power is not turned on (step A4: NO), another code number is input to the remote controller (step A6). It is again determined whether or not the source device is powered on (step A7). If the power is turned on (step A7: YES), the process proceeds to step A5 described above, and SETUP ends. Also,
If the power is not turned on (step A7: NO), another code number is input to the remote controller (step A).
8). Then, it is determined whether or not the power of the source device is turned on (step A9). If the power is turned on (step A9: YES), the process proceeds to step A5 described above and SE
When TUP is finished and the power does not turn on (Step A
9: NO), if there is a code number, repeat the same operation, terminate SETUP when the power is turned on,
SETUP if none of the code numbers apply
It becomes impossible (step A10).

Next, in the flow chart of FIG. 7, a machine is first selected (step B1). Next, the manufacturer name is selected (step B2). Further, the code number is selected (step B3). Then, the power code is output from the remote controller (step B4). Therefore, it is determined whether the power of the source device is turned on (step B5).
If the power is turned on (step B5: YES), SE
The TUP ends (step B6). On the other hand, if the power is not turned on (step B5: NO), another code number is selected (step B7). It is again determined whether the power of the source device is turned on (step B8). When the power is turned on, the process proceeds to step B6 described above and SETUP
To finish. On the other hand, if the power is not turned on (step B8: NO), if the code number is further present, the same operation is continued, and when the power is turned on to the source device, SETUP is performed.
And if none of the code numbers apply then SET
UP is impossible (step B9).

[0008]

When a plurality of codes exist in one device of a certain manufacturer, for example, a DVD player, it is necessary to repeat the input of the code number until the devices move. Further, since there are several choices for the operation on the LCD screen, it takes time to set because it is necessary to enter a deep hierarchy to enter the setting. Further, if the LCD is not provided, it is necessary to input the code number with reference to the instruction manual, so that it takes time for the input operation.
