Abstract

PURPOSE:To facilitate the operation of a recording tentative stop switch in applying a strict tape edit by displaying a picture representing the feed quantity of a 1st video tape onto a reproduced picture of the 1st video tape superimposingly. CONSTITUTION:A reproducer VTR has two video output terminals 15, 16, and a video signal V3 being the superimposition of a video signal V2 representing the count onto a linear tape counter onto the video signal V1 reproduced from the video tape is outputted from the output terminal 16. The linear tape counter outputs a count proportional to the tape feeding quantity of the video tape to the reproducer VTR 11 and displays the result on a display section 17. Thus, the timing to turn off the recording temporary stop switch is obtained while observing the display picture of the tape feed quantity and the strict tape edit is facilitated.

Description

[Detailed Description of the Invention] [Objective of the Invention] (Industrial Application Field) The present invention uses, for example, two video tape recorders (hereinafter referred to as VTRs) and selectively records the recorded contents of one VTR in the other. This invention relates to a videotape editing device for re-recording onto a VTR.

(Prior Art) When videotapes are used to store video information, the recorded content is often edited. This te.

- Editing can be done at home using, for example, two VTRs. In other words, operate the recording pause/stop switch provided on the recording side VTR, and repeat the process of recording - setting the recording pause state (switch on) - canceling the recording pause state (switch off) → recording →... By changing the playback output of the playback side VTR to the recording side VT.
It can be recorded in R.

By the way, with a VTR, even if you turn off the recording pause switch and start recording, it does not immediately record to videotape. Recording starts after m5ec~1 sec has elapsed.

Therefore, in order to perform precise tape editing, the user must take the above-mentioned delay into account and turn off the recording pause switch as soon as possible. However, it is quite difficult to properly perform such a switch-off, even with some experience.

(Problems to be Solved by the Invention) As described above, in the past, when performing strict tape editing, there was a problem in that it was difficult to operate the recording pause switch.

SUMMARY OF THE INVENTION An object of the present invention is to provide a tape editing device that allows easy operation of a recording pause switch even when performing strict tape editing.

[Structure of the Invention] (Means for Solving the Problems) In order to achieve the above object, the present invention provides a method for superimposing an image indicating the feeding amount of the reproducing side videotape on a reproduced image of the reproducing side videotape. This is what I did.

(Function) According to the above configuration, the tape feed amount is displayed as an image, so you can check the tape feed amount at the position where you want to start recording in advance, and the tape feed amount from when the recording pause switch is turned off until when recording actually starts. If the feed amount is known, the user can easily know when to turn off the recording pause switch while looking at the display image of the tape feed amount, and can easily perform precise tape editing.

(Embodiments) Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a diagram showing the configuration of an embodiment of the present invention. In the figure, reference numeral 11 is a reproduction side VTR, and reference numeral 12 is a recording side VTR. 13.14 is the playback side VTR
This is a monitor device for monitoring the reproduced images from the video tape II.

The reproduction side VTR has two video output terminals 15 and 16. One video output terminal 15 outputs a video signal 11 reproduced from a video tape. Also,
The other output terminal 16 outputs a video signal v3 in which a video signal v2 indicating a count value on a near tape counter is superimposed on a video signal v1 reproduced from the video tape.

Here, the linear tape counter refers to the VTRII on the playback side.
This is a counter that outputs a count value proportional to the tape feed amount to indicate the tape feed amount of the video tape. Note that FIG. 1 shows a display section 17 that displays the count value of this linear tape counter.

The video signal v1 is supplied to the recording side VTR 12, and only the necessary portions are selectively recorded according to the ON/OFF operation of the recording pause switch.

Further, this video signal v1 is supplied to the monitor device 13 via the recording side VTR 12, and is supplied for image display.

On the other hand, the video signal v3 is supplied to the monitor device 14 and displayed on the image display. Therefore, the monitor device 14
, the same image as the display image of the monitor device 13 and an image showing the count value of the linear tape counter are displayed in a superimposed manner. It should be noted that a case in which the above count value is displayed as a numerical value, for example, in the upper left corner of the screen is shown as a representative case (see broken line frame A).

FIG. 2 is a circuit diagram showing the configuration of a signal processing circuit provided on the reproduction side VTRII in order to obtain the two types of video signals Vl and V3 mentioned above. In the figure, a video signal v1 reproduced from a videotape is supplied to the video output terminal 15, as well as to a mixing circuit 18 and one fixed contact (a) of a switch 19. The mixing circuit 18 is further supplied with a video signal v2 indicating the count value of the linear tape counter from the video signal generating circuit 2o. The mixing circuit 18 receives these two input video signals V
1 and V2 to obtain the video signal v3, which is supplied to the other fixed contact (b) of the switch 19. The movable contact piece (c) of the switch 19 is replaced by the fixed contact piece (c) during tape editing.
b); otherwise, it is connected to the fixed contact (a).

Therefore, when editing the tape, the video signal output terminal 16 to which this movable contact piece (C) is connected is connected to the video signal v3.
is supplied, and otherwise the video signal v1 is supplied.

Note that Ps is a switch switching signal for switching the connection state of the movable contact piece (C) of the switch 19, and the connection state is switched depending on whether or not the tape editing mode is set.

As described in detail above, in this embodiment, the image of the count value of the linear tape counter is displayed superimposed on the reproduced image of the reproducing side vTR 11.

Therefore, according to this embodiment, even when performing strict tape editing, the recording pause switch can be easily operated. In other words, the switch should be operated based on the count value of the linear tape counter at the position where you want to start recording and the amount of update of the count value from when the recording pause switch is turned off until recording actually starts. Calculate the count value in advance and monitor device 1
When the count value displayed at 4 reaches this count value, the above switch can be turned off.

Further, according to this embodiment, since the video signal v2 indicating the count value is not recorded on the recording side videotape, it is possible to prevent the problem that the reproduced image becomes difficult to see when it is reproduced later.

Although one embodiment of the present invention has been described above in detail, the present invention is not limited to this embodiment.

For example, in the previous embodiment, two unitized VTRs
Although a case has been described in which the present invention is applied to a tape editing device that performs tape editing using 11.12, it goes without saying that the present invention can also be applied to a device exclusively for tape editing.

Furthermore, in the previous embodiment, a case was explained in which two monitor devices 13 and 14 were used, but these may be combined into one and the two video signals Vl and V3 may be selectively inputted by a switch.

Furthermore, in the previous embodiment, a case has been described in which a numerical value proportional to the tape feed amount is output or a count value of a near tape counter is displayed, but a figure or the like representing a change in the tape feed amount may be displayed.

It goes without saying that various other modifications can be made without departing from the gist of the invention.

[Effects of the Invention] As described above, according to the present invention, it is possible to provide a tape editing device that allows easy operation of the recording pause switch even when performing strict tape editing. .
