Multi-signal matrix switcher 1
Has a configuration as described above. Therefore, in order to give a presentation in which a plurality of video input sources are used to display a video on a plurality of video output devices using the multi-signal matrix switcher 1, first, Prior to this, a predetermined setup work is performed.

First, a plurality of video input sources such as a video device or a personal computer (not shown) to be input are connected to the respective input channels A (input 1), B (input 2), C (input 3) of the multi-signal matrix switcher 1. , D (input 4),
Connect to E (input 5), F (input 6), G (input 7), H (input 8). At this time, if the video signal of the video input source is NTSC, A (input 1) of the input channel,
Connect to B (input 2), C (input 3), D (input 4),
In case of RGB, E (input 5), F of input channel
Connect to (input 6), G (input 7), H (input 8).

Next, each output channel I (output 1), J
Video output devices such as projectors and displays are connected to (output 2) and K (output 2), and in this state, the operator first selects the input source to be used by each video output device as the output channel button group. By pressing each of the push button switches of (1) to select, each video output device is associated with a specific input source, and a video output line is constructed.

For example, in order to select the input source to be displayed by the video output device connected to the output channel I (output 1), the eight push button switches A1 and B1 forming the first output channel button group 3 are selected. , C1, D1, E1,
Of F1, G1, and H1, the push button switch corresponding to the input channel to which the input source to be displayed is connected is selectively pressed. Then, the input signal selector 7 selects one of the input channels A, B, C, D, E, F, G, and H corresponding to the pressed pushbutton switch and the output channel I (output 1). Connected via the signal conversion unit 9A to construct a first video output line consisting of an input channel and an output channel I (output 1) corresponding to the pressed push button switch.

Next, in order to select the input source to be displayed on the video output device connected to the output channel J (output 2), the eight push button switches A2 constituting the second output channel button group 5 are selected. B2, C2, D2, E2, F
Of 2, G2 and H2, the push button switch corresponding to the input channel to which the input source to be displayed is connected is selectively pressed. Then, the input signal selector 7 selects one of the input channels A, B, C, D, E, F, G, and H corresponding to the pressed pushbutton switch,
The output channel J (output 2) is connected through the signal conversion unit 9B to construct a second video output line including the input channel corresponding to the pressed push button switch and the output channel J (output 2). To do.

Next, in order to select the input source to be displayed by the video output device connected to the output channel K (output 3), eight push button switches A3 constituting the third output channel button group 6 are selected. B3, C3, D3, E3, F
Of 3, 3, G3 and H3, the push button switch corresponding to the input channel to which the input source to be displayed is connected is selectively pressed. Then, the input signal selector 7 selects one of the input channels A, B, C, D, E, F, G, and H corresponding to the pressed pushbutton switch,
The output channel K (output 3) is connected via the signal conversion unit 9C to construct a third video output line consisting of the input channel corresponding to the pressed push button switch and the output channel K (output 3). To do.

By doing so, the respective input sources are associated with the three video output devices through the selected input channel, and the specific input channel and the specific output channel are associated with each other. One video output line is constructed.

In this state, the operator operates the operation panel 2
Press the crosspoint setting button 15 on a. Then, the crosspoint select data setting unit 12 is activated. In this state, the operator depresses an appropriate push button switch among the 24 push button switches of the output channel button group, and the cross point select data setting unit 12 corresponds to the pushed push button switch. In the storage area 13a of the cross point select data memory 13, the cross point setting button 1
The construction state of the three video output lines at the time point 5 is pressed is stored.

For example, output channel I (output 1) is input channel C (input 3), output channel J (output 2) is input channel H (input 8), and output channel K (output 3) is input channel A. (Input 1) is connected and output channel I (output 1) / input channel C
In the state where three video output lines of (input 3), output channel J (output 2) / input channel H (input 8), output channel K (output 3) / input channel A (input 1) are constructed, crossing is performed. When the point setting button 15 is pressed, for example, the push button switch D2 is pressed, "IN4.OUT" in the cross point select data memory 13 corresponding to the push button switch D2.
In the storage area 13a of "2", the above-mentioned three video output lines, that is, "output channel I (output 1) / input channel C (input 3), output channel J (output 2) / input channel H (input 8)" , Output channel K (output 3) / input channel A (input 1) ”are stored. It is not always necessary to store the combination of video output lines in the cross point select data memory 13. For example, in a presentation, if the combination of video output lines is used with the initial setting of the presentation and switching is not performed during the presentation, it is not necessary to store the set combination of video output lines.

When the video output line for each output channel is constructed in this way, the operator depresses an appropriate push button switch provided on the video adjustment panel 2b on the operation panel 2a to set each video output line. In addition, output video parameters such as image quality, size, and display position are adjusted according to the connected input source and video output device. In the signal converters 9A, 9B, 9C connected to the respective output channels, the video signal (NTSC, RGB, etc.) of the input source connected to the video output line is transferred to the video signal of the video output device connected to the output channel ( N
TSC, RGB, etc.), and outputs the image. At this time, in each signal adjustment unit 10, the image quality, image size, coordinate position,
Set output video parameters such as resolution and language.

To set the output video parameters, as shown in FIG. 3, the adjustment menu MENU for the output video parameters is displayed on the screen of the video output device connected to the corresponding video output line, and the adjustment menu ME is displayed.
While referring to the NU, the operator can adjust the image adjustment panel 2b.
This is done by operating the upper push button switch 16. The operator can adjust the video parameters of each video output device on the video adjustment panel 2b of the multi-signal matrix switcher 1 while watching the video on the screen of the video output device to be adjusted. It is extremely convenient because it is not necessary to go to the video output device when it is installed in a high place.

As each video parameter, as the image quality,
There are brightness, contrast, saturation, hue, sharpness, gamma coefficient, etc., image size includes enlargement, reduction, etc., coordinate position includes horizontal coordinate, vertical coordinate, etc., and resolution includes SVGA, XGA, SXGA, etc. There are Japanese, English, and the like as languages, but these parameters are not limited to the above, and can be appropriately set as necessary.

In this way, when the output video parameters are set for each video output line, each signal adjusting section 10
Stores the adjusted output video parameter in the corresponding storage area 11a of the signal adjustment data memory 11 determined by the combination of the input channel and the output channel of each video output line. In the signal conditioning data memory 11, as already described, all possible combinations of input channels and output channels (in this case, 24
Since the storage area 11a for storing the output video parameters is provided, the output video parameters can be stored for all combinations of input channels and output channels. Accordingly, when the video output line is constructed by the same combination of the input channel and the output channel, the output video parameter is read from the storage area 11a of the corresponding signal adjustment data memory 11 and the output video parameter of the signal adjustment unit 10 is read. By using for adjustment, one-touch adjustment is completed, and it is not necessary to perform the same adjustment again on the image output line that has been adjusted once, and the work can be performed efficiently.

In this way, for each of the three sets of video output lines, when the adjustment of the output video parameters for each of the three video output lines and the storage in the signal adjustment data memory 11 are completed, the operator can further output the video if necessary. Build the line.

Even in this case, as already described, the plurality of newly constructed video output lines, that is, the combination of the input channel and the output channel constitutes the output channel button group by the crosspoint select data setting unit 12. It is stored in the storage area 13a of the cross point select data memory 13 corresponding to an arbitrary push button switch.

Since all the settings have been completed in this way, the presentation using the multi-signal matrix switcher 1 is in progress, but the operator first tries to reproduce the combination of the video output lines to be used first. Depresses a specific push button switch in the output channel button group stored by itself. Then,
The cross point select data setting unit 12 calls a combination of video output lines preset and stored by the operator from the storage area 13a of the cross point select data memory 13 corresponding to the pressed push button switch, and the input signal selector 7 The connection state is controlled so as to be set based on the combination of the video output lines. As a result, a plurality of video output lines can be set with one touch.

When a plurality of video output lines are set, the signal adjusting section 1 connected to each of the signal converting sections 9A, 9B and 9C.
0 indicates an output that has already been adjusted by the operator from the storage area 11a corresponding to the combination of the input channel and the output channel of the signal adjustment data memory 11 from the combination of the input channel and the output channel of the set video output line. The video parameter is read and the output image of the video output device is adjusted based on the output video parameter. As described above, this output video parameter is a parameter adjusted by the operator in advance for the video output line, so that the output image of the video output line is immediately adjusted to an appropriate state.

In this state, using each video output line,
The video signal is output from the input source connected to the corresponding input channel and a predetermined video is displayed on each video output device. However, when changing the combination of video output lines, the operator should change. When a combination of video output lines is stored in the crosspoint select data memory 13, by simply pressing the corresponding pushbutton switch of the pressed output channel button group, the crosspoint select data memory 13 corresponding to the pushbutton switch is stored. The combination of the video output lines stored in the storage area 13a is read out and immediately set by the input signal selector 7. At the same time, the output video parameters of the newly set video output lines are stored in the signal adjustment data memory 11 The signal is read from the corresponding storage area 11a and is read by each signal adjustment unit 10. Since immediately set, the operator need not be performed even any adjustment operation.

When the video output devices connected to the respective output channels are the same device, the adjustment by the output video parameters of the video signal may be performed only for each input channel. By doing this,
The output video parameter stored in the signal adjustment data memory 11 can correspond to only the input channel, and the memory area can be compressed.
