A method of recording and reproducing video and sound information using plural recording devices and plural reproducing devices is described. An original space in which video and sound information are to be recorded is divided into plural sections. A video recording device and a corresponding sound recording device are provided for each section of the original space. A reproduction space in which video and sound information are to be reproduced is divided into plural sections corresponding to the plural sections of the original space. Synchronous operation of plural video reproducing devices is performed simultaneously with synchronous operation of plural sound reproducing devices so that the picture and sound of each section of the original space are reproduced simultaneously in a corresponding section of the reproduction space. In this manner, synchronization of picture and sound is easily achieved, and the picture and sound of the original space are reproduced with high fidelity.

DETAILED DESCRIPTION For achieving the above described object of the invention, the method according to the invention comprises a step of recording video information for each of the plural spaces defined by dividing an original space in which video information and sound information are to be recorded and recording also sound information in each of the plural spaces simultaneously with the recording of the video information in each of the spaces, and a step of reproducing the video information recorded for each of the plural spaces in a reproduction space and reproducing also the sound information recorded for each of the plural spaces in the reproduction space simultaneously with the reproduction of the video information.
According to the method of the invention, a picture and sound corresponding to this picture in each section of the original space are reproduced respectively from their corresponding location in the reproduction space.
The picture and sound are synchronized with each other without fail and the post-processing of the sound in the studio after recording including movement of sound image and addition of reverberation by means of the simulated 4-channel system sound or the like simulated sound system is not required.
Accordingly, the post production work is greatly reduced and the video and sound information of the original space can be vividly and faithfully reproduced.
Embodiments of the invention will now be described with reference to the accompanying drawings.
