Abstract

PURPOSE: To simplify a button operation, perform easily, rapidly and correctly editing operation by successively outputting out put signals to required condition under the condition of an initial stop at both a recording side and a reproducing side. CONSTITUTION:When operating an editing stop button ASTOP, a first stop signal STP is impressed to a recording side and a reproducing side through an inverter 10, and OR circuits 15 and 23. Then, through uni-multi 11-14, to the recording side, a rewind signal REV, a reproducing signal RB and a tempo rary stop signal PAU are successively supplied. While, when operating an editing rewind button AR and the like, by an FF 23, and an AND gate 24 and the like, a reproducing signal PB, and the temporary stop signal PAU through the rewind signal REV and uni-multi 21, 22 are successively supplied to a repro ducing side under a condition that the first stop is performed. When operating an editing quick traverse button AC, similarly, an editing and recording is performed by releasing temporary stop of the recording side and the reproducing side through an operation of an editing start button ASTA. In such a manner, the button operation is simplified, and an easy, rapid and correct editing opera tion is carried out.

As is clear from the above explanation, in the replacement editing work related to the conventional technology, even if only one screen is replaced, the video tape recorder on the playback side and the video on the recording side are connected while watching the image displayed on the monitor TV. The user must also operate the tape recorder, making button operations extremely complicated. In actual editing, these operations must be performed across multiple cuts, resulting in an extremely complicated process. In particular, at the transition between cuts, the button operations for 5TP-REV→5TP-+PB-PAU must be determined in a short time, and the operations must be performed separately on the playback and recording sides. I understand.

Unless you are an expert in denominations, the current situation is to press 5TPIil and confirm before pressing the next button. This sentence almost always resulted in errors in seed manipulation, and this combined with the fact that the work took a long time.

<Object of the Invention> In view of the above-mentioned shortcomings of the prior art, the present invention simplifies complicated button operations during editing and eliminates the need for the user to judge complicated button operations. Another object of the present invention is to provide an editing auxiliary device for a video recorder that can perform editing operations simply, quickly, and accurately.

<Structure of the Invention> The present invention, which achieves the above object, focuses on the following points. In other words, if you break down the button operations that go through the stops necessary for editing as shown in Figures 8 and 4, a series of operations will repeatedly appear, and both the playback side and the recording side The next thing you know is that there are operations that can be shared at the same time.

As is clear from FIG. 8, the series of operations are of the following three types.

1) 5TP-CUE→STP→REV- on the playback side
+5TP-+PB-+PAU.

II) sTP on the playback side, REV4sTP-+
PB→PAU.

111) Recording side 5TP-REV-48TP+P
B-) PAU.

In this way, 11) and nl) are exactly the same operations,
Even fcl) includes operations similar to I) and l1l). However, the time for both the CUE operation in 1) and the REV operation in It) is indefinite.
5TP-4REV for vc, l), 1it) K
5TP-'PB-+STP in PAU and II) →
It must be noted that the PB→PAU operation may be fixed if the time is set appropriately. This is because the former differs depending on how many fltK of the videotape 1 the cut to be played next is.

Next, operations that can be performed simultaneously on both the playback side and the recording side are, as is clear from FIG. 3, stopping playback on the playback side and recording on the recording side, that is, editing. These are button operations associated with stopping and restarting playback on the playback side and recording on the recording side, that is, restarting editing.

In view of the above points, the present inventor performed the operations corresponding to l), I), Il+) and the operation associated with resuming editing with one button operation each, and performed the operation of 1LllLiil) at the beginning. Since it involves stopping, this operation is performed in 1) and II.
), II+) I came up with the idea of using one of the buttons to perform the operations.

The present invention is based on the above knowledge as the basis of its technical idea,
The configuration includes a circuit that controls the drive and stop of the video tape of the video tape recorder on the recording side and the playback side, and a circuit that is connected to the playback circuit. A first circuit means for simultaneously operating a stop circuit for stopping the running of the videotape, and a rewinding circuit for rewinding the videotape for a predetermined set time after the operation of the first circuit means is completed. a second circuit means; a third circuit means for operating a pause circuit and a playback circuit for temporarily stopping the running of the videotape on the recording side after the set time has elapsed; and after the operation of the first circuit means is completed; a fourth circuit means for operating a rewind playback circuit that rewinds and plays back a videotape on the playback side while the second operation button is operated; a pause circuit for temporarily stopping the running of the videotape on the playback side after the operation is completed, and a fifth circuit means for operating the playback circuit;
a sixth circuit means for operating a fast-forward playback circuit that fast-forwards the videotape on the playback side while the operation button is operated; The stop circuit that temporarily stops the running of the CH recorder is operated, and after the operation is completed, the fourth stop circuit is activated.
and a seventh circuit means for operating the circuit means.

<Example> Embodiments of the present invention will be described in detail below based on the drawings.

This is an explanatory diagram showing a series of operations by operating the 8TP button.
5TP-+REV-48'r'p- on the recording side of the figure
+pB-PAU operation.

The operation of this part will be explained based on FIG. 1, FIG. 2 (B)), and FIG. 3 (IL). First, when the ASTP button is pressed, the output side of the inverter 10 becomes @H level, and when the ASTP button is released, it becomes @L level.

The stop circuit operates at the rising edge of the pulse (■) formed by this, and after that, when the ASTP button is released and the ASTP button is released, the F
) One-shot multivibrator 11 operates at the falling edge of pulse ■. As a result, the pulse (2), which is the output signal of the one-shot multivibrator 11, rises at the falling edge of the pulse (2) and remains at the 1H'' level for a certain period of time, during which time the rewinding and reproducing circuit operates.

The one-shot multivibrator 12 sends out a pulse (2) whose output is @H° level at the falling edge of the pulse (2) and which lasts for a certain period of time. The stop circuit is activated at the rising edge of the pulse (2), and the one-shot multivibrator 13 is activated at the falling edge of the pulse (3). As a result, the output signal of the one-shot multi-9ibrator 13 is the pulse ■
It rises at the falling edge of the pulse ■ and remains 0H for a certain period of time.

If the level is a sustained pulse, the regeneration circuit operates during this time. The one-shot multipipe V-taper 14 outputs a full pulse (2) whose output is 12 level at the falling edge of the pulse (2) and which lasts for a certain period of time. The temporary stop circuit operates at the rising edge of this pulse (■). This temporary stop circuit is designed to continue its operation even after the pulse ■ falls until the temporary stop is canceled by operating the PAU button. That is, when the ASTP button is operated, the inverter 10° one-shot multivibrator 11, 12° 13.
The operation of V-8TP→PB-+PAU is performed in sequence to enter the playback/pause mode.

At this time, the rewinding of the cut (■) by the rewind playback operation is determined by the set time of the one-shot multipipeter 13. Even if the cut (■) of the video tape 1 is played back,
The process should have progressed to such an extent that it is guaranteed that the pause mode will be reached before the cutting point of the cut and the cut of .

Operation button AC [Edit fast forward playback (Assemble'Cu
e)] is CUE4 via stop on the playback side.
This allows the operations of STP-+REV and -+5TP-+PB4PAU to be performed. The operation associated with the operation of this operation button AC is: The number of cuts to be played in fast forward after playing a cut is not fixed, and the fast forward playback time differs depending on the position of the cut to be played next, so this time must be set in advance. I can't leave it behind. The portions related to the operations associated with the operation of the operation button AC are constructed with this point in mind.

In FIG. 1, 16 is a flip-flop circuit, 17 is an AND circuit, and one input of this AND circuit 17 is an inverting input. Also, 18, 19゜20, 21, and 22 are one-shot multivibrators, and 23 is an OR circuit, and these output terminals are STP, CUE, and REV.
, PB, and PAU are connected to a stop circuit, a fast-forward playback circuit, a rewind playback circuit, a playback circuit, and a pause circuit, respectively, of a video tape recorder (not shown) on the playback side (PB).

Fig. 2 (6) is a waveform diagram showing the signal waveforms of each part related to the above-mentioned configuration in Fig. 1, and Fig. 3 (can) is a theory BA diagram showing a series of operations by operating the AC button in the solid line part. STP→CUB-+5TP-+REV-+ on the playback side in Figure 3
This corresponds to the operation of 5TP-+PB-+PAU.

The function of this part will be explained based on Fig. 1, Fig. 2 (6) and Fig. 3 (can). First, the first stop is performed simultaneously with the stop on the recording side by pressing the ASTP button. That is, when the ASTP button is pressed, the output side of the inverter 10 goes to "H" level, and when the ASTP button is released, it goes to "L" level, and the stop circuit operates at the rising edge of pulse 0 formed thereby. Thereafter, when pulse 0 falls, the Q output of the 7-rip, 70-tube circuit 16 rises due to this falling pulse. On the other hand, when the AC button is pressed, /4 Lus■ falls. AND circuit 1
7 is an inverted pulse with the Q output. Since this AND logic is taken, the Q output is at the "H" level and the pulse (2) is at the 1L" level, that is, the output is at the 1H" level only when the AC button is operated.

Therefore, when the AC button is pressed after the ASTP button is restored, the pulse (2), which is the output signal of the AND circuit 17, rises at the same time, and the fast-forward playback circuit operates at this rise. The operation of this fast-forward reproducing circuit continues until the AC button is released and the circuit is restored.

That is, when the AC button returns, the pulse ■ goes to the "H" level, and at this rise, the 7 flip-flop circuit 16 is reset (at the same time, the 7 lip-flop circuit 23 is also reset), and at the same time, the inverting input of the AND circuit 17 is turned @L" level, so the pulse ■2>EL belt.At the falling edge of this pulse ■, the one-shot multi-by-play 718
dZ works. As a result, the stop circuit operates at the rising edge of the pulse (2), which is the output signal of the one-shot multivibrator 18. Then one shot multi vibrator 1
The one-shot multivibrator 19 operates at the falling edge of the signal 4 after the set time 8 has elapsed. Below, the one-shot multivibrators 12, 13, 14 and 1flll operate one-shot multivibrators 20, 21, 22 in sequence due to the falling of Norms ■, ■, ■, and /4I pulses ■, ■, ■, ■. At the rising edge, the rewind playback circuit, the stop circuit, the playback circuit, and the pause circuit operate in sequence. That is, if you operate the ASTP button and then operate the AC button after returning, the one-shot multivibrators 18, 19, 20
．． By sequentially operating 21°22, video tape play: 2-/KCUI-+S, TP-+REV-+5Tp4
The operation of p13→PAU is performed in sequence to set the playback/pause mode.

Operation button AR (edit rewind playback (AaHmblyRev)
iew )] is an RE via a stop on the playback side.
V-+5TP-+PB-+PAUOm (line 7M). The operation associated with the operation of this operation button AR is as follows: The cut to be played after playing the cut is not determined, and the rewind playback time differs depending on the position of the next cut to be played, so this time should be set in advance. I can't. The portions related to the operations associated with the operation of the operation button AR are constructed with this point in mind.

In FIG. 1, 24 is a flip-flop circuit, 25 is an AND circuit, and one input of this AND circuit 24 is an inverting input. Also, one shot multi vibrator 2
0, 21, and 22 are shared with the parts that operate when the AC button is operated.

FIG. 2(c) is a waveform diagram showing the signal waveforms of each part related to the above-mentioned configuration in FIG. 1, and FIG. 3(c) is the solid line portion of
This is an explanatory diagram showing a series of operations by operating the R button.
This is compatible with 4P AU4) fi works.

The operation of this part will be explained based on FIG. 1, FIG. 2(c), and FIG. 3(c). First, the first stop is performed simultaneously with the stop on the recording side by pressing the ASTP button. That is, when the ASTP button is pressed, the output side of the inverter 10 becomes 1H'' level, and when the ASTP button is released, it becomes @L'' level, and the stop circuit operates at the rising edge of the pulse 2 formed thereby. After that, when the sun fell,
At this fall 9, the Q output of the flip-flop circuit 24 rises. On the other hand, when the AR button is pressed, the pulse e falls. Since the AND circuit 25 takes the AND logic between the Q output and the inverted pulse e, when the Q output is at "H" level, the pulse e is 1L level, that is, the output is "HH level" only when the AR button is operated.

Therefore, when the AR button is pressed after the ATTP button is restored, at the same time the output signal of the AND circuit 25 rises, and the fast-forward playback circuit operates at this rise. The operation of this fast-forward reproduction circuit continues until the AR button is released and the function is restored.

That is, when the AR button returns, the pulse e becomes @H" level, and at this rise, the flip-flop circuit 24 is reset (the flip-flop circuit 16 is also reset at the same time), and at the same time, the inverting input of the AND circuit 25 is set to the 1L" level. Therefore, the pulse ■ is at the "L" level tonal. The one-shot multivibrator 20 operates at the falling edge of this pulse ■, and the one-shot multivibrator 21 is operated by the falling edge of the Δ pulses ■ and ■ in the same manner as described above.゜22 operates sequentially, and the stop circuit, regeneration circuit, and pause circuit operate sequentially with the rise of pulses ■, ■, and.In other words, if you operate the ASTP button and then operate the AR button after returning, the one-shot multi By sequentially operating the vibrators 20, 21, and 22, the video tape recorder receives REV→5TP-+.
The operations of PB-+PAU are performed sequentially to set the playback/pause mode.

Operation button AsTA [: m collection start (A+sgemb17
Start )] allows editing to be restarted by operating the playback side and the recording side at the same time. That is, AST
When button A is pressed, the output of the inverter 26 rises, and this
At the rising edge of the signal, the pause on the playback and recording sides is released and playback and recording resume, respectively. To guarantee this operation, the playback side must be in play/pause mode, and the recording side must be in record/pause mode.

Using the ASTP button, AR button, AC button, and ASTA button on the paper, edit the replacement and editing procedure shown in the 6th oral history) to the 4th oral history) to 4(c) and 3(d). ) is explained in this comparison based on the prior art. .

According to this embodiment, by operating the ASTP button, it is possible to perform the stop operation associated with the end of dubbing of a cut, which was conventionally performed separately on the playback side and the recording side, by simultaneously operating the Vc button once. Not only this, but also a series of operations to prepare for dubbing the next cut on the recording side, ie, REV-4-8TP-+PB-+PAU, can be performed. In addition, by operating the AC button and AR button, a series of operations that prepare for dubbing of the next cut on the playback side, namely CUE→5TP-+REV-+5
TP-+PB-+PAU and REV4STp-+pB-
+PAU can be performed. Furthermore, by operating the ASTA button, the playback operation on the playback side and the recording operation on the recording side, which were previously performed separately on the playback side and recording side when starting dubbing, can be performed simultaneously at the same time. It can be done by operation.

Although the editing auxiliary device according to this embodiment may be integrated into a video tape recorder, this part, that is, the circuit shown in FIG. Alternatively, the connection may be made using the control terminal. In the latter case, furthermore,
Add the PB button and PAU release button on the playback side and the PB button, PAU button, REC button, and PAU release button on the recording side necessary for editing, and perform all button operations associated with editing work with the editing auxiliary device. This will further improve operability. An example of this case is shown in FIG. In the figure, 27 is the PB button on the playback side;
