BRIEF DESCRIPTION OF THE DRAWINGS FIG.

(G1) First Embodiment In FIG. 1, reference numeral 1 denotes an editing apparatus as a whole. A desired cut is reproduced by a digital video tape recorder (VTR) 2A to 2D, and a digital video tape recorder 4 is provided.
To record.

That is, the digital video tape recorders 2A to 2D are arranged side by side in the vertical direction, and switch their operations based on control data output from the control circuit 6, respectively.

Further, a digital video tape recorder 2
The digital video tape recorders 2A to 2D are provided in parallel with a shelf device (not shown) for accommodating a plurality of tape cassettes, and input control data D _CONT to a control circuit 6 to control the digital video tape recorders 2A to 2D. By driving a tape cassette transport device (not shown) disposed between the 2D and the shelf device, the tape cassette stored in the shelf device is loaded into desired digital video tape recorders 2A to 2D, and the digital video tape is loaded. The tape cassette discharged from the recorders 2A to 2D can be stored in a predetermined position of the shelf device.

Therefore, in the editing apparatus 1, the desired digital video tape recorders 2A to 2D can reproduce the desired tape cassette only by outputting the predetermined control data D _CONT from the editor 18 to the control apparatus 6. By switching the desired digital video tape recorders 2A to 2D to the recording mode as needed, an edited video signal can be recorded.

Therefore, by sequentially outputting the control data D _CONT from the editor 18 in accordance with the editing procedure, a desired tape cassette can be automatically edited. Further, the digital video tape recorders 2A to 2D serially transmit the reproduced digital video signals to the monitor devices 10A to 10D and the color correction circuits 11A to 11D via the parallel-serial conversion circuits 8A to 8D.

Color correction circuits 11A to 11D

After correcting the hue of the digital video signal on the basis of the control data D _CONT output from the controller 12, the digital video signal is output to the switch 12 via a parallel-serial conversion circuit.

Similarly, a digital video tape recorder 2
A to 2D respectively convert digital video signals output from the switch 12 into serial / parallel conversion circuits 14A.
14D, thereby serially transmitting a digital video signal between the switch 12 and the digital video tape recorders 2A to 2D.

By serially transmitting a digital video signal in this way, the digital video signal can be transmitted over a long distance with a single cable, and a booster can be provided in the middle of the transmission if necessary to achieve a distance of 300 [m] or more. Can be transmitted.

Therefore, in the digital video tape recorders 2A to 2D and the switch 12, the area occupied by the connector can be reduced as compared with the conventional case, and the size can be reduced accordingly.

In addition, the digital video signal can be transmitted over a long distance, and a desired tape cassette can be reproduced only by transmitting the control data D _CONT to the control device 6.
The installation positions of the digital video tape recorders 2A to 2D can be freely selected with respect to the switch 12, and the usability of the editing apparatus 1 can be improved accordingly.

Further, since the digital video signal can be transmitted by one cable, the routing of the cables of the switch 12 and the digital video tape recorders 2A to 2D can be simplified, and the usability of the editing apparatus 1 can be improved accordingly. Can be. Further, the color correction circuits 11A and 11D correct the hue of the digital video signal based on the control data D _CONT output from the editor 18 and output the corrected digital video signal to the switch 12, thereby automatically adjusting the hue of the digital video signal in accordance with a preset editing order. For each cut of the digital video tape recorders 2A to 2D reproduced at the same time, the hue can be automatically corrected by a preset correction amount as required.

On the other hand, the digital video tape recorder 4 receives the digital video signal output from the switch 12 via the serial / parallel conversion circuit 16 and edits it by recording the serially transmitted digital video signal. Recorded programs.

Further, a digital video tape recorder 4
Switches the operation based on the control data D _CONT output from the editor 18 and converts the reproduced digital video signal through the parallel / serial conversion circuit 20 into the monitor device 2.
2 and a color correction circuit 23.

Like the color correction circuits 11A to 11D, the color correction circuit 23 corrects the hue of the serially transmitted digital video signal based on the control data D _CONT output from the editor 18, and then converts the color to serial data. Is output to the switch 12 via the switch. As a result, the digital video tape recorder 4 is switched to a reproduction mode as necessary, so that the recorded video can be checked through the monitor device 22.

Further, at this time, the digital video tape recorder 4 transmits the input / output digital video signal serially, and switches the operation based on the control data D _CONT output from the editor 18, thereby making the digital video tape recorder 2A 2D, it is possible to transmit a digital video signal easily and over a long distance, thereby reducing the size of the digital video tape recorder 4 and the entire editing apparatus 1, and improving the usability of the editing apparatus 1. Can be.

The monitor switch 26 switches contacts according to the control data D _CONT output from the editor 18, and is input to the digital video signal output from the parallel-serial conversion circuits 10A to 10D or the serial-parallel conversion circuit 16. The digital video signal is selectively output to the monitor device 28A. This allows you to edit
The preview image can be monitored via the monitor device 28A.

Here, in the monitor device 28A,
The time code can be superimposed and displayed on the digital video signal. Character generator (CG) 30
A to 30C create a character for super import together with its key signal, and
Serially transmitted to the switch 12 via A to 32C.

Thus, the character generators 30A to 30A
The character and the key signal created in C are also serially transmitted in the same manner as the digital video signals of the digital video tape recorders 2A to 2D and 4, thereby reducing the size of the editing apparatus 1 as a whole and improving the usability of the editing apparatus 1. Can be improved.

The imaging devices 34A and 34B capture an image for chroma key, and output the resulting color signals to the switch 12 via the camera control units (CCU) 36A and 36B. The switch 12 transmits the control data D _CONT output from the editor 18 to the control circuit 3.
Get to 8.

The control circuit 38 accesses the floppy disk (FD) 40 based on the control data D _CONT and switches the operation of the switch 12 based on the access result. That is, as shown in FIG. 2, the switch 12 has 24 input channels CH1 to CH24.
, And a digital video signal is input to predetermined input lines CH1 to CH24.

Further, the switch 12 is connected to the input line CH.
The two buses A, B, key1, and key2, each forming a cross point between 1 and CH24, are connected to serial / parallel conversion circuits 44A-44D and 46A-46D, and the serial / parallel conversion circuits 44A-44D.
And the digital video signals output from 46A to 46D are output to the mixers and mixer circuits 46 and 48.

As a result, based on the control data D _CONT output from the editor 18, the input lines CH1 to CH
24 and the cross points of the buses A, B, key1, and key2 are selectively turned on, and the digital video tape recorders 2A to 2D, 4; the mixers and mixers 46 and 48; Mix FEC circuit 46 for selectively selecting a video signal
And 48.

Further, the matrix switch circuit 41 has a program bus PGM and a preset bus PST for forming cross points between the input lines CH1 to CH24, respectively, and converts a digital video signal edited through the buses PGM and PST. Output.

That is, the matrix switch circuit 41
The digital video signal edited and outputted via the program bus PGM is output to the parallel-serial conversion circuit, and the digital video signal output from the parallel-serial conversion circuit is output to the digital video tape recorder 4 for recording.

Further, the switch 12 uses the remaining preset bus PST to secure the connection of the digital video signal to be subsequently output, and according to the control data D _CONT , converts the digital video signal previously selected by the preset bus PST to the program bus. Output via PGM. After the digital video signal serially transmitted is selected by the matrix switch circuit 41 and subjected to serial / parallel conversion, the matrix switch circuit 41
Can be simplified.

That is, when a digital video signal input through a 25-pin connector is selected by a matrix switch circuit as in the prior art, it is necessary to form input lines and buses in parallel by the number of pins of the connector. This complicates the configuration of the switch.

However, if the digital video signal serially transmitted as described above is selected by the matrix switch circuit 41 and then subjected to serial-to-parallel conversion, it is not necessary to form input lines and buses in parallel, and the matrix switch circuit 41 can be used. The switch 12 can be simplified, and the size of the switch 12 can be reduced accordingly.

In practice, in the case of this embodiment, the conventional height 880
[Mm] The switch, which has been heated more than [mm], can be downsized to a height of 88 [mm]. Mix F Eq circuits 46 and 48
Is controlled by a control circuit 38, and performs predetermined processing on the digital video signals input to the mixer / exfector circuits 46 and 48 and outputs the processed digital video signals.

That is, as shown in FIG.
When the wipe control data D _CONT is output from the mixer, the mixer EF rectifier circuits 46 and 48 receive the digital video signal output from the mixer EF rectifier circuit 46 or 48 via, for example, the bus A. The digital video signal is switched to a digital video signal input via the bus B with a wipe operation.

At this time, based on the result of the access to the floppy disk (FD) 40, the mixers and rectifier circuits 46 and 48 change the switching timing of the digital video signal sequentially in, for example, the horizontal scanning direction, thereby controlling the control data D _CONT. Execute the wipe operation in the form specified by.

Further, based on the control data previously input to the floppy disk 40 via the operation panel 49, for example, when wiping, a thick line is arranged at a cut portion (hereinafter referred to as a border) BD between two images, Set the voter to a predetermined color or blur the contour of the voter.

In this way, by executing a process such as wiping in a form stored in advance on the floppy disk 40 based on the control data D _CONT output from the editor 18, the editing process based on the control data D _CONT is performed. A detailed editing mode can be executed in a preset mode.

Therefore, for example, it is possible to repeatedly confirm the editing mode by rehearsing repeatedly, and at this time, if necessary, by updating the control data stored in advance on the floppy disk 40, processing such as wiping can be easily performed. The form can be changed, and the usability of the editing device 1 can be improved accordingly.

Actually, in a conventional editing apparatus, processing such as wipe is started based on a reference signal output from an editor. At this time, the processing such as wipe is performed in a form corresponding to the operation of the operation panel. The processing is performed. Therefore, when rehearsal is to be repeated later, it is necessary to operate the operation panel again, and it is difficult to reproduce the edited form as it is, and there is a disadvantage that the operation is complicated.

As described above, by executing the processing such as the wipe in the form stored in the floppy disk 40 in advance, the fine editing form at the time of the editing processing can be executed in the preset form. The form can be reproduced many times as it is.

Further, the mixers and mixers 46 and 4
8 is a character generator 30A to 30C, an imaging device 3
4A, 34B and the key signals output from the special effect device 52, the selected and input images are combined, thereby fitting the chroma key effect or the reduced image C to the image A as shown in FIG. To form a composite image.

Further, the mixer circuits 46 and 4
Numeral 8 outputs the edited digital video signal to the monitor devices 50A and 50B via the parallel-serial conversion circuit, whereby the editing process can be confirmed via the monitor devices 50A and 50B.

Further, in the switcher 12, during the editing operation, the digital video signal selected by the program bus PGM is serially transmitted to the monitor device 28B, whereby the edited digital video signal is monitored via the monitor device 28B. Have been made to gain.

The special effect device 52 receives the control data D _CONT output from the editor 18 in the same manner as the switch 12 to the control circuit 54 and, based on the control data D _CONT ,
By accessing the floppy disk 56, the input digital video signal is processed based on the access result. That is, the special effect device 52 receives the digital video signal and the key signal output from the switch 12 via the serial / parallel conversion circuit, and serially transmits the digital signal with the special effect to the switch 12.

At this time, the control circuit 54 operates the operation panel 49 in advance to add special effects such as reduction, enlargement, rotation, and deformation of the image in accordance with the processing procedure set on the floppy disk 56. That is, as shown in FIG. 5, for example, when control data D _CONT for instructing a page turn operation is input, a portion set in advance on the floppy disk 56 is used to start a page turn (in the lower left corner in FIG. ), The input digital video signal is subjected to page turn processing based on data such as the time required for the page turn operation.

Further, when control data D _CONT for instructing image reduction / enlargement is input, the input digital video signal is converted based on data such as the reduction / enlargement ratio and center position set in advance on the floppy disk 56. To process.

Thus, by processing the digital video signal in accordance with the processing procedure previously stored in the floppy disk 56 based on the control data D _CONT output from the editor 18, for example, iteratively rehearsing and processing an image by a special effect. You can check the condition several times.

Therefore, by updating the control data stored in the floppy disk 56 in advance as necessary,
The speed of reduction / enlargement can be easily switched, and the usability of the editing apparatus 1 can be improved accordingly. In practice, in a conventional editing apparatus, processing of a special effect is started based on a reference signal output from an editor, and the processing of the special effect is executed in a processing procedure according to an operation of an operation panel. It has been made like that.

Therefore, when rehearsal is to be repeated later, it is necessary to operate the operation panel again, and it is difficult to reproduce the special effects several times, and the operation is complicated.

As described above, by executing the special effect processing according to the processing procedure stored in the floppy disk 56 in advance, the special effect at the time of the editing processing can also be executed at a preset speed or the like. It can be reproduced several times depending on the situation. Furthermore, the special effect device 52
The digital video signal to which the special effect has been added is output to the switch 12 via a parallel-serial conversion circuit together with the key signal.

Thus, in the special effect device 52,
By serially transmitting the digital video signal, the area occupied by the connector can be reduced and the size can be reduced.
By outputting the digital video signal to which the special effect is added to the switch 12 together with the key signal, FIG.
The special effects device and the mix effector circuit can be used in combination so that a separate screen is fitted under the screen where the page turns as shown in (1), and the usability of the entire editing device 1 can be improved accordingly. .

Further, in this embodiment, the control circuit 54
Can input and output control data to and from the control circuit 38 of the switch 12.
A special effect is given in response to the editing operation of step 2.

As a result, the image C reduced by the special effect device 52 is fitted into the image B as shown in FIG.
While wiping from image A to image B, image C can be rotated and fitted into image A during the time required for the wiping, as shown by the broken line. Thus,
Control data D between the special effect device 52 and the switch 12
By inputting and outputting the _CONT , the processing of the switch 12 can be used in combination with a special effect, and the usability of the editing apparatus can be further improved.

The editor 18 displays input data input via the keyboard 60 on the monitor device 62, and outputs control data D _CONT in response to the input data. That is, at the time of rehearsal of the editing work, the control data D _CONT is output in response to the input data, so that the tape cassette desired by the operator can be set in the digital video tape recorders 2A to 2D.
To play.

Further, the switch 12 and the special effect device 5
2 to add special effects and the like set by the operator operating the operation panel 49. Further, at this time, the control data D _CONT is supplied to the color correction circuits 11A to 11D.
Is output and each digital video tape recorder 2A-2
The hue of the digital video signal output from D is corrected.

Further, at the time of the rehearsal, the control data D _CONT output to the control circuit 6, the switch 12 and the special effect device 52 is recorded on the floppy disk 64, so that the operation of the rehearsal can be repeated as many times as desired by the operator. It is made to get repeatedly.

Thus, in the editing apparatus 1, the editor 18 outputs control data D _CONT to the control circuit 6, the digital video tape recorder 4, the color correction circuits 11A to 11D, the switch 12, and the special effect device 52. The entire editing apparatus 1 is controlled in an integrated manner.

Therefore, the rehearsal can be repeated as many times as necessary only by operating the keyboard 60, so that the usability of the editing apparatus 1 can be improved. Further, when predetermined input data is input through the keyboard 60, the editor 18 converts the control data D _CONT output to the control circuit 6, the switch 12 and the special effect device 52 at the time of rehearsal to the identification data of the tape cassette and the time code. And the like, and sequentially recorded on the time-series floppy disk 64 in the order designated by the operator, whereby the control data D _CONT necessary for controlling the editing apparatus 1 is sequentially arranged in the editing order.
Create an edit data list consisting of

On the other hand, when actually editing the tape cassette, the control data D _CONT is output in the order of the edit data list after waiting for the input of predetermined input data. Thus, the editor 18 controls the switch 12 and the special effect device 52 so as to execute the work set in advance on the floppy disks 40 and 56, and the control circuit 6 controls the desired digital video tape recorders 2A to 2D to set the desired tape cassette. Is controlled to be played.

Further, a digital video tape recorder 4
Then, the edited digital video signal is recorded, while the color correction circuits 11A to 11D correct the hue of the digital video signal for each cut. Thus, even when actually editing the tape cassette,
