Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a method for controlling audiovisual equipment, and more particularly, to a method for centrally and remotely controlling various types of audiovisual devices used in lecture halls, conference halls, classrooms, and the like.
[0002]
[Prior art]
In recent years, in lecture halls, conference halls, classrooms, and other gathering venues, multiple images are output from video, DVD, OHC, personal computers, projectors, and other devices. Data etc. can be displayed. Of course, in such a meeting place, sound equipment such as a microphone and lighting equipment are also installed.
[0003]
And presenters etc. operate each apparatus at the timing. However, each of these devices is provided with an individual remote control terminal and can be operated individually, so when operating these devices with a remote control terminal, Since it corresponds, there was a problem that the operation was troublesome.
In addition, the volume of lighting and sound equipment may be controlled during image output operations, but this lighting control and volume control are often performed by venue engineers, not the presenter, and timing deviations are likely to occur. There was a problem.
[0004]
On the other hand, for home AV equipment, a technique has been proposed in which a remote control terminal capable of operating a plurality of types of equipment can be used to control AV equipment installed at locations away from a plurality of rooms (Patent Document 1). ).
[0005]
[Patent Document 1]
Japanese Patent Laid-Open No. 3-58696 [0006]
[Problems to be solved by the invention]
However, the control method of the prior application is a remote control method for viewing home AV equipment centrally installed at a specific location at a different location. When the AV device is operated at one location, the system is connected by the system. The same program will be watched at all locations (rooms). In addition, since this system is intended for home AV equipment, the remote control terminal does not incorporate a system for controlling lighting equipment or audio equipment. It could not be applied to a device that centrally controls audiovisual equipment in conference halls or classrooms.
[0007]
The present invention pays attention to such points, and controls audiovisual equipment in a venue such as a lecture hall, a conference hall, or a classroom, and venue environmental equipment equipment such as lighting equipment and audio equipment, with a single remote control terminal. The purpose is to provide.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, the present invention described in claim 1 is a remote control terminal that outputs an infrared control signal, a light receiving unit that receives the infrared control signal, a system controller connected to the light receiving unit, A switcher that is switched by a control signal from the system controller, audiovisual equipment such as OHC, DVD, VTR, audio equipment, personal computer, etc. connected to the switcher, and a power controller for each audiovisual equipment. The audio-visual device to be used is selected, and the selected audio-visual device is operated by a remote control terminal.
[0009]
[Effects of the Invention]
In the present invention, since a plurality of audiovisual devices can be selected and operated with one remote control terminal, the presenter can easily operate the audiovisual devices according to the contents of the presentation. In addition, when an operation switch for venue environment maintenance equipment such as an air conditioner or lighting equipment is incorporated in the same remote control terminal, the venue environment can be improved in accordance with the operation of the audiovisual equipment.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 shows a schematic configuration of a remote control system to which the present invention is applied.
This system is installed in lecture halls, conference halls, and classrooms, such as projectors (1), OHC (2), DVD (3), VTR (4), audio equipment (5), personal Audiovisual equipment such as a computer (6), a television, and a display are arranged in the meeting room or in the equipment room formed adjacent to the meeting place.
[0011]
One remote control terminal (7) for operating the audiovisual device is disposed in the meeting place. The remote control terminal (7) outputs an infrared control signal, and an infrared light receiving unit (8) for receiving the infrared control signal output from the remote control terminal (7) is arranged on the ceiling of the meeting place. is there.
[0012]
In the equipment installation section (9) disposed in the equipment room or the meeting place, a system controller (10) and a switcher that is switched by a control signal from the system controller (10) are arranged. . The system controller (10) and the infrared light receiver (7) disposed on the ceiling of the meeting place are connected by wiring, and the projector (1), OHC (2), DVD ( 3) Audiovisual equipment such as VTR (4), audio equipment (5), personal computer (6), etc. are connected to each other. Each output of the audiovisual equipment such as the projector (1), OHC (2), DVD (3), VTR (4), audio equipment (5), personal computer (6), etc. is sent to the switcher (11). An output signal from an audiovisual device that is configured to be input and is controlled based on a control signal from the system controller (10) is output via a switcher (11), and is selected in the meeting place. The video is displayed.
[0013]
Furthermore, the system controller (10) controls each power source of the audiovisual device described above via the power supply controller (12), and inputs an audio signal of the audio device in the assembly room and an audio signal of the audiovisual device. A control signal is transmitted to the mixer (14) so that the volume in the meeting place can be controlled. The system controller (10) transmits a control signal for raising and lowering the screen (15) installed in the assembly room.
[0014]
In the audiovisual equipment control system having the above-described configuration, the presenter operates the remote control terminal (7) in order to selectively operate any audiovisual equipment in the meeting hall as the presentation contents progress. The infrared signal emitted from the remote control terminal (7) is received by the infrared light receiving unit (8) installed on the ceiling of the meeting place and sent to the system controller (10). In the system controller (10), the audiovisual device selected by the remote control terminal (7) is operated, and an output signal from the audiovisual device is output via the switcher (11), and an image is displayed in the meeting place. It will be.
[0015]
In this remote control terminal (7), the operation buttons of the audiovisual equipment installed in the meeting place, the sound equipment such as the microphone system of the meeting place, and the projection equipment such as the screen are concentrated on one remote control terminal.
[0016]
Furthermore, in facilities where multiple meeting places (rooms) such as schools and public halls are installed, the audiovisual equipment installed in each meeting place is unified, and the output signal from each remote control terminal (7) is sent. If they are matched, a specific remote control terminal (7) can be used in any meeting place (room), and the remote control terminal (7) is compatible.
[0017]
FIG. 2 shows another embodiment of the method of the present invention. The remote control terminal (7) controls the audio-visual equipment and the acoustic equipment (5) such as a microphone system at the meeting place and the projection equipment (15) such as a screen. A control function of the lighting equipment (16) and the air conditioning equipment (17) in the hall is provided.
[0018]
Reference numeral (18) in the figure denotes a plasma display that receives an output signal from the switcher (11) and displays an image in the meeting place.
[0019]
【The invention's effect】
In the present invention, since a plurality of audiovisual devices can be selected and operated with one remote control terminal, the presenter can easily operate the audiovisual devices according to the contents of the presentation. In addition, when the operation switch of the venue environment maintenance equipment such as an audio device or a lighting device is incorporated in the same remote control terminal, the venue environment can be improved according to the operation of the audiovisual equipment.
