JPH0276168A - Editing/controller for magnetic recording/reproducing machine - Google Patents

Abstract

PURPOSE:To edit not only a video but also sound volume at small mistakes by setting a sound recording level by means of a program control. CONSTITUTION:An editing start point (in point) 13 and an editing completion point (out point) 14 are inputted to an edit controller 10 to control an editing device 9, next a sound recording level 15 is inputted on a digital data basis, and after the setting is completed, a program is executed. Further, the video and sound are edited from the in point 13 up to the out point 14 set by the editing device 9, simultaneously the digital data of the sound recording level are transmitted from the edit controller 10 to the editing device 9, the digital data are converted into analog data by the D/A converter 12, and the data determine the sound recording level during the editing. Thus, the sound recording level can be simultaneously edited with the picture editing.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a magnetic recording and reproducing machine editing control device for editing video and audio using a magnetic recording and reproducing machine.

2. Description of the Related Art First, a configuration example of a conventional magnetic recording/reproducing machine editing control device is briefly shown in FIG. 3, in which numeral 1 denotes an editing device constituted by a conventionally used magnetic recording/reproducing machine. To explain its contents, numeral 2 is a magnetic recording/reproducing machine (hereinafter referred to as VTR) for playing back video and audio, and is used as a source machine for editing. 3 is the same VTR, used for recording video and audio, and used as an editing machine. 4.5 is a video signal and an audio signal sent from the VTR 2 as a source device to the VTR 3 as an edit device. Reference numeral 8 denotes an editing control device that controls the editing device 1. The main signals input and output between the editing device 1 and the editing control device 8 are a command signal 6 for operating the VTR;
There is a control signal (hereinafter referred to as CTL) or a time code (hereinafter referred to as TC) 7, etc.

In the conventional magnetic recording/reproducing machine editing control device configured as described above, the editing control bag M (hereinafter referred to as edit controller) 8 sets the editing start point and editing end point, and the editing device! ! CTL or Te3 input from ■
Video and audio editing operations are performed by transmitting command signals 6 for operating the VTR using the VTR.

Problems to be Solved by the Invention However, in the conventional configuration as described above, the edit controller 8 only sets the editing start point and editing end point, so the audio recording level must be adjusted manually. There was a problem.

SUMMARY OF THE INVENTION In view of the above, an object of the present invention is to provide a magnetic recording/reproducing machine editing control device that enables editing of an audio recording level at the same time as image editing.

Means for Solving the Problems In order to achieve the above object, the present invention includes means for setting the audio recording level in an editing device that edits video and audio by program control.

Effect of the present invention With the above-described configuration, not only the editing start point and editing end point but also the audio recording level settings are programmed and inputted in advance, and by executing this program, it is possible to record not only the video but also the audio. Record-level editing is also possible.

Embodiment FIG. 1 shows a magnetic recording/reproducing machine editing control device in one embodiment of the present invention. In FIG. 1, reference numeral 9 denotes an editing device composed of a magnetic recording/reproducing device, and its contents are almost the same as the conventional editing device 1 shown in FIG. 3, so detailed explanation thereof will be omitted.

However, here we use a digital-to-analog converter (hereinafter referred to as DA).
(referred to as converter) 11 is attached. 10 is.

An edit controller (
This edit controller 1 is an edit control bag W).
Editing device from scratch! VT as the main signal transmitted to
There are a command signal 6 for operating R, a signal 12 for setting an audio recording level, etc. Also, the main signals transmitted from the editing device 9 are as follows.

This is CTL (TC) 7, which is the same as the conventional one. Note that other detailed input/output signals in this device will be omitted.

Next, the settings input to the edit controller 10 are shown in FIG. 2, where 13 is the editing start point (hereinafter referred to as the in point), and 14 is the editing end point (hereinafter referred to as the out point).
In both cases, CTL or TC values are used.

15 is the setting of the audio recording level, which is input as digital data.

The operation of the magnetic recording/reproducing machine editing control device of this embodiment configured as described above will be described below.

First, input the IN point 13 and OUT point 14 to the edit controller 10. Next, input the audio recording level 15 using digital data (for example, when the maximum value of the audio recording level is 5, the digital data is 5 ,4,3,2
．． 1. It is given by either O. Please note that the input is
(by key operation).

After completing these settings, run the program. II collection device! 9 edits the video and audio from the in point 13 to the out point 14 set by the edit controller 1.
Digital data at the audio recording level is transmitted from 0 to the editing device I9. This digital data is stored in the editing device 9.
The A converter 12 converts it to analog data, and this data will determine the audio recording level during editing.

As described above, according to this embodiment, the audio recording level, that is, the volume, can be edited and controlled without manual operation by inputting the settings of the audio recording level into the program using the edit controller IO.

In the above embodiment, the audio recording level 15 was set by selecting five levels of digital data, but by setting the audio to fade in or fade out, the audio being edited can be faded in or out. It can also be faded out. In order to do this, it is necessary to use the edit controller lO as a fade-in (fade-out) signal by using digital data that will obtain an AC trajectory when converted to analog data.
Provided by internal microcomputer control. Then, if the audio recording level of the Ig collector 19 is adjusted using an electronic volume, this signal causes audio fade-in,
This allows for fade-out editing.

In addition, by using this electronic volume, high-speed fade-in (fade-out) of the audio can be realized under the control of a microcomputer.

Furthermore, by assembling a program for the edit controller 1O, continuous editing of video and audio recording levels can be performed.

DETAILED DESCRIPTION OF THE INVENTION According to the present invention, by setting the audio recording level through program control, it is possible to edit not only the video recording level, but also the audio recording level, that is, the volume, easily and with fewer mistakes. can.
