ABSTRACT:
A video signal recording and reproducing apparatus replaces at least one of a group of a predetermined number of frames of a main signal from one video camera to a sub signal frame from another video camera on the same time base as that of the main signal and records, and upon reproduction, executes the recording video signal by an ordinary reproducing process and reproduces and displays the main signal and still reproduces the intermittent sub signal frames, thereby reproducing the sub signal like a frame sending. The recording and reproducing apparatus sets one of the video signals which are obtained from two or more video cameras into the main signal and sets the other remaining video signals into the sub signals and records those main and sub signals and conveniently distributes those signals and reproduces.
