<p>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 (2) sequentially selects one of the video signals (SvN) in prescribed order, and identifying signal adders (10a, 10b) add an identifying signal (Sid) representing a corresponding camera number (N) to the selected video signal (SvN) and generate recording signals (Sr1, Sr2). A recording signal processor (11) modulates the recording signals (Sr1, Sr2) and recording magnetic heads (16a, 16b) record them on a magnetic tape (4). Reproducing heads (15a, 15b) reproduce a recorded recording signal (Sr') from the magnetic tape (4) and a reproducing processor (14) demodulates the signal. A camera number detector (23) detects the identifying signal (Sid) from a demodulated video signal (Sr2'). Memory (24) stores the demodulated video signal (Sr2') 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.</p> |
