Abstract
The present invention is a video signal recording and reproducing apparatus for recording and reproducing video signals (SvN) inputted from a plurality (n) of different cameras (CMn). A frame switcher (,) sequentially selects one of the video signals (SvN) in prescribed order, and identifying signal adders (,) add an identifying signal (Sid) representing a corresponding camera number (N) to the selected video signal (SvN) and generate recording signals (Sr,, Sr,). A recording signal processor (,) modulates the recording signals (Sr,, Sr,) and recording magnetic heads (,) record them on a magnetic tape (,). Reproducing heads (,) reproduce a recorded recording signal (Sr′) from the magnetic tape (,) and a reproducing processor (,) demodulates the signal. A camera number detector (,) detects the identifying signal (Sid) from a demodulated video signal (Sr,′). Memory (,) stores the demodulated video signal (Sr,′) in relation to the detected identifying signal (Sid), thereby allowing high-speed and normal-speed replay of video from a desired video signal source without video signals from a plurality of video signal sources mixed into.
