2. Description of the Related Art When many people simultaneously watch an image displayed on an image monitor such as a television picture tube, a plurality of image monitors are integrated, and one image is displayed by integrating the plurality of image monitors. A multi-screen video display device is used. In this case, one image is enlarged,
The image is displayed on four video monitors composed of two horizontal pixels or nine video monitors composed of three vertical pixels and three horizontal pixels.

[0003] Also, when it is necessary to simultaneously watch a plurality of images, a multi-screen image display device is used. For example,
In a disaster prevention information providing system operated by a local government, a multi-screen image display device is installed in a disaster response room of a disaster prevention center. The multi-screen video display device includes analog video VTR video of a disaster-stricken area, television broadcast video, and digital video transmitted from a weather satellite, weather note / warning information, and AMeDAS analysis rainfall information. Are displayed.

FIG. 20 shows a block diagram of a conventional multi-screen display device. A multi-screen display device 152 illustrated in FIG. 20 includes a multi-screen display unit 142 including a screen selection unit 151, a switcher 141, a plurality of video monitors, and a video enlargement unit 143.
It is composed of The switcher 141 includes a TV tuner 161, a VTR 162, an optical disc reproducing device 163,
Connected to the digital video controller 164,
The video information output from the TV tuner 161, VTR 162, optical disk reproducing device 163, and digital video controller 164 is received. Screen selection unit 151 described later
When it is specified to output one video to one video monitor of the multi-screen display unit 142 by the switch, the switcher 141 outputs the video to the corresponding video monitor. When one image is designated to be output to a plurality of image monitors by the screen selection unit 151, the switcher 141
Outputs the video to the video enlarging unit 143. The switcher 141 receives the video output from the video enlarging unit 143 and outputs the video to a corresponding video monitor.

[0005] The screen selection unit 151 is provided with a TV tuner 16.
1. The operator receives a selection as to which video monitor of the multi-screen display unit 142 to display video information output from the VTR 162, the optical disk reproducing device 163, and the digital video controller 164, and outputs the video information to the switcher 141. The selection includes a case where one video is displayed on one video monitor and a case where one video is displayed on a plurality of video monitors.

[0006] When displaying the video output from the switcher 141 on a plurality of video monitors of the multi-screen display unit 142, the video enlarging unit 143 magnifies the video by a factor of 4 or 9 and enlarges the expanded video. 4 in the same size as the original
The image is divided or divided into nine, and four or nine images are generated, and the generated four or nine images are output to the switcher 141.

When using the multi-screen display device 152 shown in FIG. 20 to display video information output from the TV tuner 161, VTR 162, optical disk reproducing device 163, and digital video controller 164 on the multi-screen display unit 142, The operator operates the TV tuner 161, the VTR 16
2. The user selects the video to be reproduced by operating the optical disk reproducing device 163 and the digital video controller 164, and then selects the video monitor for displaying the selected video using the screen selection unit 151.

As described above, for the analog video, only by switching the input of the source signal, the multi-screen display unit 14
2 can be displayed. For example, a signal from the TV tuner 161 which is one of the analog images can be selected for the analog image only by tuning. Also, V
The reproduction of the TR can be performed by using a control signal to perform cueing and reproduction / stop. To control the VTR device, it is only necessary to connect to the input of the VTR device on the control side and issue an instruction. Accordingly, the display status of the video information can be controlled by operating the video information switching button disposed on the operation panel called the AV console, for displaying the analog video on the multi-screen display unit 142. Further, the VTR can be controlled by providing a play / stop button or the like on the AV console so that an operation instruction can be given.

On the other hand, in the creation of digital video,
Requires drawing software to draw on the screen. For example, when displaying an image received from the weather satellite Himawari, a program for drawing bitmap data received from the weather satellite on a background map is required. There is no general method for drawing these bitmap data, and it is necessary to create a digital video creation program individually.The control interface with the digital video creation device is provided for each piece of digital video information. It is necessary to create a method that takes characteristics into account.

As a result, the above-mentioned AV console does not control the apparatus for creating a digital image, but separately gives an instruction to the digital image creating apparatus using the digital image controller 164. Now, the characteristics of the video source providing side as viewed from the receiving side are as follows when comparing the case of analog video and the case of digital video.

An analog video source is created by a company such as a television broadcasting company, and a video is obtained by receiving a broadcast wave, sending the received signal to a TV tuner, and adjusting the channel by the TV tuner. It can be carried out. After receiving, there is no need to perform any particular image processing, and the received video is displayed as it is on the multi-screen display unit 1.
42. Further, the transmitted video information is one source per channel, and in order to receive a plurality of videos, it is sufficient to prepare a plurality of channels. Therefore, for television reception,
A receiver is prepared for the number of channels, and only a button on which an input and an output are arranged on a matrix for switching individual TV images which are outputs from the receivers is provided on the AV console. The display of the screen image can be controlled.

In the case of digital video, it is the digital video creation device that produces the video. The device is usually a computer such as a personal computer or a workstation, and requires a program for creating digital images. Further, even if the video creator is located elsewhere, a means for obtaining the generated video information is required, and for that purpose, it is necessary to use a method such as file transfer using a communication line. Therefore, it is difficult to arrange a button on the AV console and give a digital video transmission instruction or the like by operating the button.

Further, since a personal computer or a workstation is more expensive than a TV tuner and it is difficult to install a computer for the number of channels for creating an image, the image to be created is selected by a program.
A plurality of digital images are created by one computer. For television image creation, TV tuners for the number of channels are usually provided.
By using each signal line as an input to the switcher, the operation of the AV console can be simply performed as a connection between input and output. In addition, the video being received
Since the images are displayed on the individual TV tuner monitors, by arranging the TV tuners on the wall surface, it is possible to list what kind of images are displayed on each channel. If the TV tuner has a function of receiving a channel switching instruction, a single TV tuner can receive a plurality of channels. In this case, it is necessary to provide a channel switching button on the AV console.

[0014]

However, the operator selects a video to be reproduced by using a video reproducing device such as a TV tuner, a VTR, an optical disk reproducing device, and a digital image controller. The video monitor for displaying the selected video must be selected using the selection unit 151.

That is, the operator needs to perform the operation on the AV console and the control of the digital video controller on separate devices, and can perform the switching operation of the analog video by a simple operation. There has been a problem that the operation of switching images is complicated. In addition, the operator needs to give an instruction to create a digital image in order to create the digital image on site, and since it is necessary to create a plurality of digital images in one digital image controller, the operator has to issue a switching instruction. There was a problem that operation was required.
