It is characterized in that randomly reproduced video signals are recorded on a recording video tape recorder.

(Example) Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

A block diagram of a video editing system according to the present invention is shown in FIG.

In FIG. 1, 1 is a personal computer that can program and store recording formats, 2 is a playback video tape recorder, 3 is a recording video tape recorder,
4 is a digital telopper.

The playback video cheap recorder 2 is a video tape recorder that plays back a recorded tape (not shown), and its system controller 2a receives control signals output from the personal computer 1 according to the above program. The system controller 2a, according to commands of control signals input from the personal computer 1,
To cause the playback video Cheap Record 2 to stop, play, fast forward, rewind by one, pause, etc. These stop, play,
The position of the playback tape for fast forwarding, rewinding, pausing, etc. is detected by the personal computer 1 based on a counter signal input from the tape output terminal 2b of the playback video tape recorder 2. Also, at the time of starting playback, etc., a first permission signal is output to the personal computer 1 for causing the personal computer 1 to judge whether or not the i!ii surface is stable.

The playback video tape recorder 2 performs random playback according to instructions from the personal computer 1, and outputs the played video signal to the digital telopper 4.

On the other hand, the recording video tape recorder 3 receives the video signal reproduced by the reproduction video tape recorder 2 and the personal computer 1 at a predetermined timing according to the above program.
This video tape recorder records the output of a digital telopper 4 to which characters and graphic signals are added.A stop/run signal output from a personal computer 1 is input to its system controller 3a.

The system controller 3a sends a recording tape (not shown) to the recording video tape recorder 3 in accordance with a stop/run signal command input from the personal computer 1.
stop and run.

The system controller 3a also sends a second command that instructs the recording video tape recorder 3 to prohibit key reception during recording.
A permission signal is output to the personal computer 1.

In the video tape recorder editing system explained above,
A series of controls for randomly playing back the playback video Cheap Record 2, and having the recording video Cheap Record 3 seamlessly record and edit the playback screen or the playback screen including the computer screen, etc., are included in the operating program of the personal computer 1. It can be done automatically.

Next, an example of the operation of the video tape recorder editing system shown in FIG. 1 will be described with reference to chart 70 shown in FIG.

In this flow, after the count value of the counter 2b of the playback video tape recorder 2 becomes "50" from 00J to "50", the count value of the counter 2b becomes [10].
(The video tape recorder 3 records a 5-second slow playback screen from the moon.

As shown in FIG. 2, the personal computer 1 starts a series of program steps from step 100, and in step 101, the counter 2 is started by a count signal input from the counter 2b of the playback video cheap record 2.
It is determined whether the count value of b is 100.

When the count value is not "00", the personal computer 1 executes a loop consisting of steps 101 to 105, and causes the playback video cheap record 2 to perform fast forwarding or rewinding until the count value becomes "00". .

When the count value becomes "00", the personal computer 1 puts the recording video tape recorder 3 into standby mode in step 106, causes the playback video tape recorder 2 to execute playback in step 107, and at this time, the playback video tape recorder 2 executes playback. It is determined whether the playback screen is stabilized based on the first permission signal input from the system controller 2a. When the playback screen becomes stable, the personal computer 1 executes step 109, causes the recording video tape recorder 3 to execute recording, and determines in step 110 whether or not the count value has reached "50". When the count value reaches "50", the personal computer 1 executes step 111 and temporarily stops the recording video tape recorder 3. In steps 111 and 112, the personal computer 1 instructs the playback video tape recorder 2 to read the count value of the counter 2b. Perform fast forwarding until the value reaches "100".
