Abstract

PURPOSE:To edit a tape with no overlap nor gap, by delivering a signal to pause other producing/reproducing actions synchronously with a pause during the video recording or reproduction. CONSTITUTION:A video output terminal 3 and an audio output terminal 4 of a reproducing VTR1 are connected to a video input terminal 5 and an audio input terminal 6 of a video recording VTR2, respectively. Furthermore, a pause controlling output terminal 8 of the VTR1 is connected to a pause controlling input terminal 7 of the VTR2. Then the VTR1 and VTR2 are set in a reproduction pause mode and a video record pause mode, respectively. Under such conditions, the pause mode of the VTR1 is released. Thus the pause mode of the VTR2 is also released simultaneously with the VTR1. In addition, a simultaneous pause is also possible for both VTR1 and 2. As a result, a pause or its release is possible simultaneously for >=2 VTRs. This device avoids the generation of overlaps or gaps with tape editing.

Description

[Detailed description of the invention] This release F! AIf'i magnetic recording and reproducing device (hereinafter referred to as VTR)
(referred to as K).

When editing a tape using all conventional VTRs, first connect the signal output terminal of the VTR for playback (hereinafter referred to as VTR1) and the signal input terminal of the VTR for recording (hereinafter referred to as VTR2). Connecting. After locating the beginning of the tape to be edited on the VTR 1, the tape is placed in a playback pause state, and the VTR 2 is fed through the tape at the portion desired to be recorded and placed in a recording pause state. Next, the two machines simultaneously release the pause and perform an editing operation, but in manual operation, this operation tends to cause a time +&IθXJ shift, resulting in a disturbance in the edited image. For example, if the pause on VTR 1 is released too early, the beginning part that you want to capture will not be recorded, and if the pause on VTR 2 is released too soon, noise or other TV double signals will be recorded on the edited tape. However, there are some drawbacks.

The present invention eliminates the above-mentioned drawbacks and provides V T and R in which a plurality of VTRs can be operated synchronously and iQ.

In order to achieve this purpose, when a pause or stop release operation is performed during recording or playback, this issuing EA synchronizes with this operation and performs a pause or stop release operation for other VTI's (1).・The input terminal for the pause control, which is already used in VTRs, is used to output the input signal that can be used to control α. The 1111π gear-shaped set including the 1111π gear-shaped set is short-circuited to the ground, and in the paused state it is an oven, and the oven control E: Menu I; ill 5, the 1st generation circuit is the 1st
It is configured as shown in the figure. In Figure 1, (10 is a switch circuit, and (8) is a control output terminal. The switch circuit 110 is normally open, and when the terminal (9) is temporarily stopped. The oven is activated only when No. 48 is input, indicating that .Figure 2 shows an example of a system that uses two VTRs to perform green i-collection.

It is connected.

The pause control output terminal (8) is connected to the pause control external input terminal (7).

Set the recording to pause status and use V T RIll.
If the operation for canceling the stop every time is performed, the temporary stop 1) in (8) and the control output terminal will be in the oven state, and the temporary stop of VTR+21 will also be canceled at the same time. Also, both VTR1l
N21 can also be temporarily stopped in synchronization.

As described above, by providing this VTR9 pause signal output terminal, two or more VTRs can be paused or stopped synchronously without any deviation in time jf+j.

Mistakes due to lags in operation time, such as missing tI, can be prevented. In addition, it is sufficient that the VTRK control output terminal on either the recording side or the playback side is set to 7'.
You can use ゛ as is.
