  • Patent number: 3999218
    Abstract: A video signal recording and reproducing apparatus for stop motion pictures comprises a memory device for recording a signal, for example, a signal during the period of time of one field corresponding to one scene from telecast video signals, means for extracting a signal corresponding to any one instantaneous scene from video signals produced from a television receiver set or the like for recording on said memory device, and means for effecting repeated reproduction of the recorded signal to produce a video signal for a stop motion picture. The memory device is embodied by a field memory device provided with a magnetic recording medium such as a magnetic disc or magnetic sheet effecting one revolution during the period of time of one field. The employment of the video signal recording and reproducing apparatus for stop motion picture permits a receiver to view, as a stop motion picture, any instantaneous motion picture he desires during the period of viewing the telecast.
