Abstract

PURPOSE:To reproduce a sound field matching a video by recording a sound field control code on a monaural signal track in synchronization with the video. CONSTITUTION:An audio/visual signal reproduced by a VTR1 is inputted to a sound field variable device 6. An audience selects the desired sound field while watching the video, and inputs the control code corresponding to it into an input means 2. The input code is recorded on the monaural signal track of the VTR by a recording means 3, the control code is inputted to the device 6, and the sound field corresponding to the control code is reproduced. Further, when it is reproduced by the VTR1 again, the recorded code is reproduced by a reproducing means 4, and outputted to the device 6 by an output means 5. Since the control code is recorded in synchronization with the video, even if the control code is not inputted by the means 2, the sound field matching the video can be repeatedly reproduced.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is a method for repeatedly recording and recording arbitrary sound fields synchronized with images of a video tape recorder (hereinafter referred to as VTR).
This is a control code input device for a sound field variable device that can reproduce sound.

Conventional technology In recent years, CD, DAT, and S
-VHS, high-definition, etc. are becoming increasingly popular.

Furthermore, in recent years, there has been an increasing need for new AV system devices that combine video and sound.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of a conventional control code input device for a sound field variable device capable of creating an arbitrary sound field will be described below with reference to the drawings.

FIG. 2 shows the configuration of a control code input device for a conventional sound field variable device. In FIG. 2, 7 is an input means for inputting an audio signal (in this case, it is a VTR), 8 is an input means for inputting a control code for controlling the sound field variable device, and 9 is a sound field variable device. .

The operation of the conventional control code input device for the sound field variable device configured as described above will be described below.

The audio/visual signal inputted by the input means 7 is inputted to the sound field variable device 9 .

At the same time, the listener selects a sound field that matches the scene while viewing the video, and inputs a control code corresponding to the sound field using the input means 8. The input control code is input to the sound field variable device, and a sound field corresponding to the control code is reproduced. With this configuration, it was possible to reproduce a sound field synchronized with the video.

Problems to be Solved by the Invention However, with the configuration method described above, the sound field that matches the video can only be played once, and when the same video (scene) is to be played again, the same operation as the previous time is performed. There was a need.

In view of the above problems, the present invention provides a control code input device for a sound field variable device that can repeatedly reproduce a sound field synchronized with a video of a VTR.

Means for Solving the Problems In order to solve this object, a control code input device for a sound field variable device according to the present invention is constructed as follows.

An input means for inputting a control code to control the sound field variable device, and a VT capable of recording and reproducing stereo and monaural signals.
It is comprised of a recording means for recording the control code on an R monaural signal track, a reproduction means for reproducing the recorded control code, and an output means for outputting the reproduced control code to the sound field variable device. There is.

By providing an input means for inputting a control code for controlling the acting sound field variable device, and a recording means for recording the control code on a monaural signal track of a VTR, the control code for a sound field that matches the video can be simultaneously output as a stereo signal. Can be recorded. Further, by providing a reproduction means for reproducing the recorded control code and an output means for outputting the control code, it becomes possible to repeatedly reproduce a sound field synchronized with the video.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention.

In FIG. 1, reference numeral 1 denotes a VTR 12 capable of recording and reproducing stereo and monaural signals, a control code input means, 3 a control code recording means, 4 a control code reproduction means, 5 a control code output means, and 6 a variable sound field. It is a device.

The operation of the control code input device for the sound field variable device configured as described above will be described below.

In FIG. 1, audio/visual signals reproduced by a VTR 1 are manually input to a sound field variable device. The listener is
While viewing the video (scene), a desired sound field is selected, and a control code corresponding to the sound field is input into the input means 2.

The input control code is recorded by the recording means 3 on a monaural signal track of the VTR. At the same time, the control code is input to the sound field variable device, and a sound field corresponding to the control code is actually reproduced. When the VTR is played back again, the recorded control code is played back by the playback means 4 and outputted to the sound field variable device 6 by the output means 5. Since this control code is recorded in synchronization with the video, it is possible to repeatedly reproduce the sound field synchronized with the video without inputting the control code using the input means 2.

As described above, by recording a sound field control code that matches the video (scene) in the monaural signal track of the VTR, it is possible to repeatedly reproduce a sound field that is synchronized with the video.

Furthermore, since the recording location is a monaural signal track of a VTR, it can be used without modifying the VTR.

FIG. 3 shows a tape backing unit for a VTR capable of recording and reproducing stereo and monaural signals. In the present invention, a control code is recorded on the monaural signal track 10 shown in FIG. 3 and reproduced.

An input means for inputting a control code for controlling the sound effect field variable device of the invention, and a VT capable of recording and reproducing stereo and monaural signals.
By providing a recording means for recording the control code on the R monaural signal track, it is possible to record a sound field control code that matches the video. Further, by providing a reproduction means for reproducing the recorded control code and an output means for outputting the control code, it becomes possible to repeatedly reproduce a sound field synchronized with the video.
