Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic equipment control system for controlling electronic equipment such as a VTR by an operating device.

[0002]

2. Description of the Related Art Like a high-definition theater, a VTR
In a system that controls a plurality of electronic devices such as (video tape recorder) and VDP (video disc player) at one place, a control device is separately provided to control each device. An operation device is connected to the control device via a communication unit, and an operator controls each electronic device through the control device by operating the operation device.

In a system such as the one described above,
Since the operating device and each electronic device are arranged at positions distant from each other, it is difficult for the operator to determine what state each electronic device is currently in and what kind of operation should be performed next. Met.

Conventionally, in order to solve such a problem,
The operating device is provided with a display unit, and the control device sends message data of a plurality of bytes indicating the state of the electronic device to the operating device and displays the message on the display unit to provide information to the operator.

However, in this method, since the control device directly sends the message data having a large number of bytes to the operating device, there is a problem that the load on the control device increases and the processing speed of the control device decreases.

[0006]

SUMMARY OF THE INVENTION The present invention has been made in view of the drawbacks of the above-mentioned conventional example, and it is possible to inform an operator of information such as the state of electronic equipment without increasing the burden on the control device. It is an object of the present invention to provide a control system for electronic equipment that can be used.

[0007]

In the electronic equipment control system of the present invention, the operating device includes a display unit and a memory, and the memory stores in advance a code number and message data corresponding to the code number. The control device sends the code number corresponding to the message to be displayed to the operating device according to the state of the electronic device, and the operating device sends the message data corresponding to the code number sent from the control device to the message data. It is characterized in that it is configured to call from a memory and display a message on the display unit.

[0008]

According to the above construction, the control device only sends the code number corresponding to the message to be displayed to the operating device, and since the code number has a smaller data amount than the message data, the control device itself is not burdened. This reduces the processing speed of the control device.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a block diagram of a control system of this embodiment.

In FIG. 1, reference numeral 1 is an operating device, and the operating device 1 comprises an interface 2, a CPU 3, a read-only memory (ROM) 4, a key input section 5, and a display section 6. Reference numeral 7 is a control device, 8 is VDP, 9 is a VTR, 10 is a still image file device, 11 is a switch, 12 is a display device such as a display, and 13 is an audio device such as a speaker.
The operations of the VDP 8, VTR 9 and still image file device 10 are controlled by the control device 7. Further, the switch 11 is used for the VDP 8, VTR 9, and still image file device 1.
The signal from 0 is used to select which signal is to be transmitted to the display device 12 and the audio device 13, and is switched and controlled by the control device 7.

A plurality of code numbers and message data corresponding to each of the plurality of code numbers are stored in advance in the memory 4 of the operating device 1. That is, when the key input unit 5 is operated, the CPU 3 sends a command code corresponding to the operation to the control device 7 via the interface 2.
The control device 7 responds to the command code by VDP8,
VTR 9, still image file device 10, and switch 11
And sends the code number of the message to be displayed on the CPU 3 via the interface 2. The CPU 3 stores the message data corresponding to this code number in the memory 4
Then, the message is displayed and sent to the display unit 6, and the message is displayed on the display unit 4.

Next, the operation of this embodiment will be specifically described.

A code number and message data for displaying a message as shown in Table 1 corresponding to the code number are stored in the memory 4 in advance. The code number is composed of "M" which means a message and 2-byte data such as "01". Further, the message data specifies data of a maximum of 16 bytes indicating the message content as shown in Table 1, data for specifying the display position, and whether or not to delete the previously displayed message. It is composed of many data such as data.

[0015]

[Table 1]

First, when the key input unit 5 is operated to turn on the power source of each device such as the VDP 8, the VTR 9 and the still image file device 10, the control device 7 receives a command code from the CPU 3 via the interface 2. When each of the above devices is started up, a code number'M01 'is sent. The CPU 3 sends the code number “M01” to the memory 4, and the code number “M” stored in advance in the memory 4 is stored.
Call the message data corresponding to 01 '. The C
The PU 3 sends the message data to the display unit 6, and the display unit 6 displays the message "Kikiwo Select."

Next, for example, when reproducing the VTR 9,
Press the VTR key of the key input unit 5, and then press the play key. The CPU 3 determines which key is pressed, and when the key is valid, sends a command code corresponding to the reproduction of the VTR to the control device 7 via the interface 2. In response to the code, the control device 7 issues a reproduction instruction to the VTR 9 and switches the switch 11 to the VTR side so that the display device 12 displays the reproduced image of the VTR.
3 to output the reproduced voice of the VTR. Further, the control device 7 sends the code number "M02" to the CPU 3, calls the prestored message data corresponding to the code number "M02" sent from the CPU 3 from the memory 4, and displays it on the display unit. A message "VTR Saisei" is displayed on the CPU 6 according to an instruction from the CPU 3.

When the VTR 9 is stopped, the stop key of the key input unit 5 is pressed. The CPU 3 and the control device 7 operate in the same manner as described above to stop the VTR 9. Further, the control device 7 sends the code number “M03” to the CPU 3, and the C
The PU 3 calls out the message data stored in advance corresponding to the code number "M03" from the memory 4 and sends it to the display unit 6 to display "VTR CHECK".
Then, after a lapse of a predetermined time, the control device 7 sends the code number "M01" to the memory 4 and causes the display unit 6 to display the message "Kikiwo Selective Disable" corresponding to the code number.

Further, when the VDP 8 is selected, when the VDP key of the key input unit 5 is pressed, the control device 7 causes the code number '
M04 'is sent to the memory 4 and the display section 6 displays "Bangouwo techno te te chi". When the number of the program to be reproduced is entered by the key input unit 5, the controller 1 sends the controller 7 a code number "M05" and the display unit 6 displays "1 bansaisei".

When a key relating to a device not connected to the control device 7 is operated, the operating device 1 causes the control device 7 to operate.
The code number'M06 'is sent from the display unit 6 and "Kiki error" is displayed on the display unit 6.

In the control system as described above, the control device 7 sends the code number corresponding to the message to be displayed to the operating device 1, and the operating device 1 calls the message data corresponding to the code number from the memory 4 and displays it. Part 6
Is configured to display that message,
The control device 7 only needs to send a code number corresponding to the message and having a small amount of data, the load on the control device 7 itself is reduced, and the processing speed is increased.

[0022]

According to the present invention, it is possible to provide a control system for electronic equipment in which the load on the control device when displaying a message on the display unit of the operating device is reduced and the processing speed of the control device is increased.
