The operation of the system in which the sound and the image reproduced by the conventional sound field varying device configured as described above are synchronized will be described. First, in order to synchronize with the image in FIG. 2 (a), first, the image signal of the image reproducing device 2 is input to the image monitor 5, and while the image reproduced by the image monitor 5 is being viewed, the image signal is present. In order to reproduce the sound field, the menu change switch 1 controls the sound field changing device 3.

Sound field changing device 3
The output signal of is input to the sound reproducing device 6, which enables sound field reproduction synchronized with the image.

Problems to be Solved by the Invention However. In the above configuration, since the sound field varying device is controlled while observing the image, it is difficult to accurately synchronize with the image. In addition, there is a problem in that correction cannot be made when the sound field varying device is erroneously controlled.

The present invention has been made in view of the above problems, and provides an editing machine for a sound field varying device, which can be accurately synchronized with an image and can be easily corrected.

Means for Solving the Problems To achieve this object, the editing device for a sound field varying device of the present invention stores a time code written in synchronization with an image and a code for controlling the sound field varying device as a set. A storage means, a program means in which a code for controlling the sound field varying device in advance, and a time at which the code is output are written as a set, and a time code from the outside is read to store the storage means or the program means. And the control means for outputting the paired code to the sound field varying device when the time code is written in the above-mentioned time code.

Operation With this configuration, the sound field varying 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 varying device are assembled and stored in the storage means. To go. If you want to reproduce this, the control means reads the time code written in synchronization with the image from the outside, compares this time code with the time code stored in the storage means, and when they match. , The code stored in combination with the time code is output to and controlled by the sound field varying device. This makes it possible to accurately reproduce the sound field control device once controlled. In addition, the program means preprograms a set of a time (time code) for synchronizing the image with the program means and a code for controlling the sound field varying device. As with the storage means, the control means reads the time code synchronized with the image, compares it with the programmed time code, and when they match, changes the sound field of the code written in pairs. Output to the device. This makes it possible to easily correct by controlling the programmed time code or control code if the sound field variable device is accidentally controlled or if the synchronization with the image is not accurate. Will be accurately synchronized with.
