An audio system in which a plurality of audio devices are upgraded is composed of, for example, a record player 1, a tuner 2, an amplifier 3, a tape player 4, a CD player 5, etc. as shown in FIG. It is also possible to build an AV system by upgrading the equipment.

This audio or AV system is set up with the amplifier 3 having an input selector as a main device in order to perform a cooperative operation between the devices, and a display 3b having a plurality of display windows 6 as shown in FIG. It is provided with.

The display window 6 of the display 3b is provided with a display for illuminating a plurality of display colors for identification display. For example, a green LED 6a, an amber LED 6b, and a red LED 6c can be provided to emit three colors.

That is, the state of the cooperative operation can be identified and displayed by the display colors of the three LEDs. For example, the input device that is currently selected and connected and operating is displayed in red, green is displayed when the cooperative operation is 100% operable, amber is displayed when the cooperative operation is operable with easy operation, and no cooperative operation is possible Can display an identification such as an unlit display.

The operation state of each device of the AV system and the identification display will be described with reference to the flowchart of FIG.

When the power is turned on by operating the power switch 3a of the amplifier 3 which is the main device (step S1), a microcomputer (hereinafter, referred to as a microcomputer) built in the amplifier 3 transmits an initialization code to each device via a system control bus line. (Step S2).

Each device that has received the initialization communication information calls back to the amplifier 3 via the bus line together with the device code, using information on whether or not the cooperative operation between the determined devices is possible as the cooperative operation level (step S3).

If this callback does not return at all, for example, the microcomputer of the amplifier 3 determines that all the cooperative operations are not possible for the video equipment of the route R1 (step S6), and turns off all the display LEDs of the display window (step S6). Step S7).
