BEST MODE FOR CARRYING OUT THE INVENTION Embodiment 1. FIG. 1 is a configuration diagram showing a matrix switcher of the first embodiment. In the figure, 1 is a matrix switcher main body, 2 is an input 1
An input terminal as a data input section consisting of to input n, 3
Is an output terminal as a data output unit consisting of outputs 1 to m, and 4 is a cross point provided at the intersection of the input terminal 2 and the output terminal 3, and relates any input terminal 2 to any output terminal 4. Therefore, these are connected or disconnected.
Reference numeral 5 is a control unit for transmitting the switching information to the CPU 6. The control unit 5 has an operation button for switching the crosspoint 4 and an interface function of receiving crosspoint information from a calculator or the like. The control unit 5 may exist inside the matrix switcher body 1. Input 1
The input n and the outputs 1 to m have the same configuration even if the matrix switcher handles not only a video signal (whether a still image or a moving image) but also an audio signal or other data.

A recording unit 7 holds data, and holds a video signal, an audio signal or other data. Since the recording unit 7 inputs the data to be held,
Alternatively, it is provided with a rewrite input section for rewriting already held data, and a data input / output section 8 for writing data to the recording section 7 is connected to this rewrite input section.
The data input unit 8 is composed of a device such as a personal computer or a video. The data input unit 8 need not always be connected to the recording unit 7, and may be connected as needed. Further, when the data initially input to the recording unit 7 is used without being rewritten, the data input / output unit 8 is unnecessary. Reference numeral 9 is a reproduction unit for reading out the data held in the recording unit 7, and 10 is a reproduction output unit for outputting the data read out by the reproduction unit 9 having a crosspoint 11 associated with the output terminal 3.

First, the recording unit 7 receives a video signal from the data input / output unit 8 and holds it. This video signal is read by the reproducing unit 9. The reproduction output unit 10 that outputs the video signal read by the reproduction unit 9 receives the input (n
+1), and the video signal can be supplied to any output terminal or all output terminals by controlling the cross point 11.

Therefore, even if there is no input signal from any of the input terminals 2, the video signal recorded in the recording section 7 is output from an arbitrary output terminal 3 under the control of the crosspoint 11 and is not shown separately prepared. The image can be displayed on the monitor.

Therefore, according to the first embodiment, it is possible to supply a separately prepared signal when the input signal is interrupted with a relatively simple structure.

Further, according to the first embodiment, since it is not necessary to provide a switch at the input terminal, there is no need to worry about a switch failure.

Embodiment 2. In the second embodiment, a case where the video signal from the input terminal 2 is recorded as a still image will be described. FIG. 2 is a configuration diagram showing a matrix switcher according to the second embodiment. In the following embodiments including this embodiment, the same or corresponding parts as those in the first embodiment are designated by the same reference numerals and the description thereof will be omitted.
In the figure, 12 is a recording section for obtaining information input from the input terminal 2, and 13 is a rewriting input section having a cross point 14 at the intersection with the input terminal 2. The rewriting input unit 1
Reference numeral 3 is the positioning of the output (m + 1) of the matrix switcher, and the recording unit 12 records the signal output from the output (m + 1).

In the second embodiment, when the video signal is input from the input terminal 2, the control section 5 is set at a predetermined timing.
The cross point 14 is controlled by. As a result, the video signal from the designated input is output from the rewrite input unit 14 and supplied to the recording unit 12. The recording unit 12 records the supplied video signal in the recording unit 5. The image stored in the recording unit 5 can be rewritten, of course. Further, rewriting of the held image may be rewritten by the recording unit 12 or the data input / output unit 8.

Therefore, according to the second embodiment, even if the data to be recorded in the recording unit 7 is rewritten, it is not necessary to prepare an information source such as the data input / output unit 8.

Embodiment 3. In the second embodiment, the case where the video signal from the input terminal 2 is recorded as a still image has been described, but in the third embodiment, an example of switching and storing the still image or the moving image will be described. FIG. 3 is a configuration diagram showing a matrix switcher according to the third embodiment. In the figure, reference numeral 15 is a recording designation section, which switches the recording mode of the recording section 7 according to the type of data from the input terminal 2.

When there is a request for capturing a video signal, the recording designation section 15 determines whether the data input from the input terminal 2 is a still image or a moving image. If the data input here is a still image, the recording designation unit 15 sets the still image recording mode, and the control unit 5 sets the crosspoint 1
A still image at the timing when 4 is switched is recorded and recorded in the recording unit 7. If the input data is a moving image, the recording designation unit 15 sets the moving image recording mode, and the control unit 5
Records a moving image for a predetermined time designated by the recording designation unit 15 from the timing when the cross point 14 is switched, and records it in the recording unit 7.

Therefore, according to the third embodiment, it is possible to switch the recording mode according to the type of the input data and perform the recording.

Multiple 0s are prepared. That is, in the fourth embodiment, when recording data such as a video or audio signal input from the input terminal 2 in the recording unit 7, a plurality of data are stored. The reproduction output unit 10 is prepared for each of the plurality of data. Therefore, according to the fourth embodiment,
Outputs 1 and 3 can output different images, or outputs 1 and 3 can output different audio. It is also possible to output video from the output 1 and output audio from the output 3.

Embodiment 5. The fifth embodiment is provided with a plurality of rewriting input units. FIG. 5 is a configuration diagram showing a matrix switcher of the fifth embodiment. In FIG. 5, a plurality of rewrite input units 13 are prepared. In the fifth embodiment, a plurality of rewriting input units 13 and a plurality of reproduction output units 10 are prepared. Therefore, the degree of freedom with respect to the selection width of the data to be recorded by the recording unit 7 and the output from which the recorded data is output increases. Further, in the fifth embodiment, since a plurality of rewriting input sections 13 are prepared, data from different inputs can be recorded in the recording section 7 at the same time.
