Abstract

PURPOSE:To attain accurate synchronization with a picture and to simplify the correction by storing a time code written synchronously with the picture and a code controlling a sound field variable device in pairs, comparing the result with a time code written in a program means and outputting the code in pairs when they are coincident. CONSTITUTION:A program circuit 9 references a time code and a picture reproduced by a picture reproducing device 7 in advance to write a time code for synchronizing with the picture and a code controlling a picture reproducing device 13. In this state, when a picture, an audio signal and a time code are reproduced by the picture reproducing device 7 again, and when the time code to be inputted and a time code written in the program circuit 9 are coincident, a code to control the picture reproducing device is outputted and the picture reproducing device 13 reproduces the sound field corresponding to the code. Thus, even if the synchronization between the picture and the reproduced sound is deviated and controlled in mistake, it is simply corrected and accurate synchronization of the picture and the sound field to be reproduced is attained.

Description

DETAILED DESCRIPTION OF THE INVENTION The field of industrial application yet to be invented is to synchronize the sound played by a sound field variable device that processes a music signal or the like to reproduce an arbitrary sound field and the image played by an image playback device. The present invention relates to an editing device for a sound field variable device used for playback.

BACKGROUND OF THE INVENTION In recent years, technologies that combine images and sound to improve the sense of reality, such as old FiVTRs and future high-definition TVs, have been attracting attention. Furthermore, in the field of acoustics, a sound field variable device that can reproduce any sound field has been developed, and there is a desire to develop a device that combines this with images.

FIGS. 2(a) and 2(b) are block diagrams of a system for synchronizing the image reproduced by a conventional sound field variable device and the image reproduced by an image reproducing device.

In FIGS. 2(a) and 2(b), l is a menu changeover switch that outputs a code to control the sound field variable device;
is an image playback device that records images and sounds and plays them back; 3
1 is a sound field variable device that reproduces an arbitrary sound field; 4 is a recording device that records the image and sound reproduced by the image reproduction device 2 and the code output from the menu changeover switch;
Reference numeral 5 denotes an image monitor that monitors images reproduced by the image reproducing device, and 6 denotes an audio reproducing device that actually reproduces the acoustic signal output from the sound field variable device 3.

The operation of a system that synchronizes the sound and image reproduced by the conventional sound field variable device configured as described above will be described. First, in FIG. 2(a), in order to synchronize with the image, first input the image signal of the image reproduction device 2 to the image monitor 5, and while watching the image being reproduced on the image monitor 5,
In order to reproduce the sound field that matches the image, the sound field variable device 3 is controlled by the menu changeover switch l. At this time, the sound field to be reproduced is determined by manually inputting the acoustic signal output from the image reproduction device 2 to the sound field variable device 3, inputting the processed signal to the sound field reproduction device 6, reproducing it, and recognizing the Vfi. . Further, the image signal and audio signal output from the image reproducing device 2 are input to the recording device 4 and recorded.

At the same time, the control code for the sound field variable device 3 output from the menu changeover switch l in synchronization with these signals is input to the recording device 4 and stored. Therefore, the storage device 4 records three things: an image signal, an audio signal, and a control code synchronized therewith.

A system for reproducing what has been recorded by the recording device 4 as described above is shown in FIG. 2(b). The image signal output from the recording device 4 is input to the image monitor 5, and the image is reproduced. Further, the acoustic signal output from the recording device 4 is input to the sound field variable device 3, and the control code output from the recording device 4 is also input to the sound field variable device. The output signal of the sound field variable device 3 is input to the sound reproduction device 6, thereby making it possible to reproduce the sound field in synchronization with the image.

Problems to be Solved by the Invention However, in the above configuration, since the sound field variable device is controlled while viewing the image, it is difficult to accurately synchronize with the image.

Further, there is a problem that it is not possible to correct the case where the sound field variable device is controlled by mistake.

The present invention has been made in view of the above-mentioned problems, and it is an object of the present invention to provide an editing machine for a sound field variable device that can accurately synchronize with an image and can easily make corrections.

Problems and Means for Solving the Problems To achieve this object, the editing device for a sound field variable device of the present invention stores a time code written in synchronization with an image and a code for controlling the sound field variable device as a set. A storage means, a code for controlling the sound field variable device, a programming means for programming a set time to output the code, and a time code for reading an external time code and matching the time code written in the storage means or the programming means. and control means for comparing and, when they match, outputting the paired codes to the sound field variable device.

Operation With this configuration, the sound field variable device is controlled while monitoring the time code written in synchronization with the image, and the time code at this time and the code for controlling the sound field variable device are combined and stored in the storage means. attitude(.

If you want to reproduce this, the control means reads the time code written in synchronization with the external image, compares this time code with the time code stored in the storage means, and then - At this time, the code stored in combination with the time code is output to the sound field variable device for control. This makes it possible to accurately reproduce what is controlled by the -degree sound field control device. In addition, a set of time (time code) for synchronizing with the image and a code for controlling the sound field variable device are programmed in advance by the programming means (as in the case of the storage means). , the control means reads the time code synchronized with the image, compares this with the programmed time code, and when they match, outputs the code written as a set to the sound field variable device. If you control the sound field variable device by mistake or the synchronization with the image is not accurate, it can be easily corrected by changing the programmed time code or control code. This allows accurate synchronization.
