Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an AV control system that centrally controls and manages a plurality of AV (audio/video) devices.

[Background of the invention]

Recently, a plurality of AV devices in the home are being organically connected through home buses that are spread throughout the house. For example, company A's television receiver, company B's VTR (video tape recorder), company 0's monitor device, company D's amplifier (audio amplifier), etc. are combined and centrally controlled and managed by a controller. is planned.

[Problem to be solved by the invention]

However, in such a system, as the number of devices increases, the operational burden on the user increases, and the operations need to be performed in a sequential manner, which may make the system extremely complicated.

The present invention has been made in view of these points, and its purpose is to provide an AV control system that allows controlling a plurality of AV devices, checking their status, etc. using video information.

[Means to solve the problem]

To this end, the present invention provides a monitor device, a plurality of AV devices that output AV signals to the monitor device, and a plurality of AV devices that output AV signals to the monitor device.
'In an AV system equipped with a controller that is connected to the AV device via a control bus and controls each AV device, the controller is provided with a display memory so that a video signal of data related to the AVi device can be output to the monitor device. I made it.

〔Example〕

Examples of the present invention will be described below. FIG. 1 is a block diagram showing the system configuration.

Reference numeral 1 denotes a monitor device having an audio reproduction section and a video reproduction section, into which AV signals (audio signals and video signals) from a plurality of AV devices are input. As an AV device, TV tuner 2
, VTR 3, LD/CD 4, amplifier 5, etc. 6 is a controller that receives a control optical signal from a remote control transmitter 7. Note that LD is an abbreviation for laser disc player, and CD is an abbreviation for compact disc player.

The AV signals from these AV devices 2 to 5 and the controller 6 are output to the monitor device 1 via the AV signal line group 8. Further, the monitor device 1, the AV devices 2 to 5, and the controller 6 are interconnected by a control bus 9.

FIG. 2 is a block diagram showing the internal configuration of the controller 6. As shown in FIG. 61 is a bus interface that connects the above-mentioned control bus 9 and internal bus 62; 63 is a remote control transmitter 7;
64 is a CPU (central processing
unit), 65 is a program ROM in which a control program is written, 66 is a pictograph ROM in which pattern data for pictograph display is written, 67 is a character ROM in which character data for display is written, and 68 is a monitor device 1 (7) CRT.
The CRTC 169 that controls the (cathode ray tube) is a video RA that stores the video signal pattern to be displayed on the monitor device 1.
It is M.

This controller 6 receives control data from the remote controller 7 while receiving control data (status information of device A) from the control bus 9 to control command data (on/off, etc.) to the equipment. A video signal for displaying the control status on the monitor device 1 is sent out via the AV signal line group 8 along with the bus 9 .

Here, the teletext protocol (hardware, software) is used as the display function.

FIG. 3 is a diagram showing a display screen (CRT screen) of the monitor device 1. As shown in FIG. Here, in addition to the original video, the AV devices 2 to 5 are identified and displayed with characters, for example, for control or status confirmation, and their statuses (on/off, type of operation, etc.) are indicated. In this diagram, tuner 2
is on and receiving satellite broadcasting channel 11, VTR3
indicates that four channels of television broadcasting are being recorded, the LD/CD 4 is off, and the amplifier 5 is manually processing the audio signal from the tuner 2 and processing it in Dolby mode.

FIG. 4 is a diagram showing the operation surface of the remote control transmitter 7 described above, and this operation surface is provided with a display key 71, an up cursor key 72, a down cursor key 73, and an execution key 74. 75 is an infrared emitting section.

In this embodiment, if the display key 71 of the remote control transmitter 7 is pressed when it is not operating, a power/display remote control signal is input to the controller 6, and the controller 6 turns on the power/display to the monitor device 1. A command signal is sent. As a result, the monitor device 1 is powered on and the initial message r is displayed there. For example, as shown in FIG. 3, this message includes the character display "tuner",
Displayed as 'LD/CD J%', 'Amp', etc. Initially, all of the AV devices 2 to 5 are powered off. Therefore, when the cursor keys 72 and 73 are pressed to move the cursor 11 to, for example, tuner j and the execution key 74 is pressed, a detailed selection menu screen for tuner j is displayed next (not shown). Therefore, by pressing the cursor keys 72, 73 or execution key 74 based on this screen, you can select the channel or broadcast format (normal TV broadcast, satellite broadcast, etc.) after turning on the power. The same applies to the VTR, LD/CD, and amplifier. Fig. 5 shows an explanatory diagram of the operation using the remote control transmitter 7.

In this way, while looking at the screen of the monitor device 1, by alternately pressing the cursor key and execution key of the remote control transmitter 7 while responding to the displayed contents in an interactive search format, the power supply and operation of the AV equipment can be controlled. The mode etc. can be arbitrarily selected.

Also, if you press the display key 71 when you are currently working,
The current status of each AVi device 2 to 5 is displayed, for example, as shown in FIG. 3, and the status can be confirmed.

In the above embodiment, there is a possibility that the remote control transmitter 7 may be operated a considerable number of times before finally obtaining the necessary device status. To solve this problem, for example, a mode selection key may be provided so that a specific menu mode can be directly selected.

〔Effect of the invention〕

As explained above, according to the present invention, the controller is provided with a display memory so that the video signal of data related to AV equipment can be output to the monitor device.
There is an advantage that the status of the I-device can be checked on the monitor device, and furthermore, the AV equipment can be controlled while checking the display on the monitor device.
