Abstract

PURPOSE:To simplify the operation of an acoustic video equipment by selecting a primary function and making drivable the necessary devices in relation to the action of the primary function. CONSTITUTION:A video disk player VD4, for example, is selected out of the acoustic video AV equipment names displayed on a CRT 1. In this case, an equipment memory part 4a stores an additional function memory 5c in addition to the primary function in order to complete this function. Then the memory including the contents of the memory 5c are read out via a control bus line 9 after the VD4 is selected and stored in a commander memory part 5b. Then only a list of functions is displayed on the CRT 1. Then a desired function is selected with push of a button key (k) of a remote controller 8. Thus the necessary functions related to the primary function are also driven by the output of the memory 5c which completes the drive of the selected function. In such a way, the operation of an AV equipment is simplified.

Here, the rVDJ displayed on the CRTl by the remote control 8
To the button key that corresponds in arrangement to the section of ! When you press , the device VD4 is selected, and the list of functions available with the VD4 is PLAY, 5KIP, and 5T as shown in Figure 4 (d).
It will be displayed like OP.

This is the same as the case of displaying the function name described above.
The button key k1 pressed corresponding to the device display rVDJ
At the same time as pressing 1, the contents of the device memory section 4a from C0M5 to VD4 are read out via the control bus line 9, and the function list stored in the COM memory section 5b via the control bus line 9 is read out and displayed. At this time, the COM memory section 5b contains the function characters of the device VD4 specified by the button key ktt, as shown in FIG. 4 (c).
Two call codes for that function are stored. In addition,
This is to erase and update the memory of other function lists already stored in the COM memory section 5b, so that only the function list of the selected device is always stored.

Also, CRTI is PLAY as shown in the same figure (d).

It has the ability to display nine types of functions: 5KIP, 5TOP, etc., but as shown in the function list in the same figure (c), function group VD1. When the VDr[ has more than 9 functions in total, the functions can be displayed by pressing the page key 8c on the remote control 8.
Nine functions of the VDH are displayed instead of the type, and of course, by pressing the button key corresponding to the function displayed at that time, the function can be operated.

The conventional example has been explained above using the case of VD4 as an example.
In the case of D7, the operation is exactly the same, and detailed explanation will be omitted.

(Problem to be Solved by the Invention) However, in the conventional configuration described above, the drive of only one device, for example, the VD, is controlled, and the AMP for listening to the audio accompanying the drive of the VD is controlled by the operator. It is necessary to separately turn on the power or turn on the TV, which is a troublesome operation.

In view of the above, it is an object of the present invention to provide an AV equipment device that can be controlled and driven without requiring the above-mentioned troublesome operations.

(Means for Solving IIM) The present invention achieves the above object by selecting the AV device name displayed on the CRT, selecting the function name of the device similarly displayed on the CRT, and driving the device. In an AV device capable of transmitting the stored contents from the device memory section to the COM memory section, the stored contents of the function list and associated functions that are related to each function and drive other devices are also sent. When a device is selected using a control key, the COM displays only the function list of the selected device on the CRT, and when a function is selected based on the display, the selected function is activated. This is achieved by a configuration that makes it possible not only to drive the above-mentioned accompanying functions related to that function.

(Function) According to the present invention configured as described above, it is possible to drive other related devices with a -degree operation, which is equivalent to actually performing two control operations, and the AV4i! M device operation becomes easier.
