ABSTRACT:
An apparatus and method for recording and reproducing extended periods of video information on a longitudinal tape recorder without losing synchronism or image quality. The composite video signal, and synchronization signals extracted therefrom, are recorded in spatial registry on separate channels of a longitudinal tape recorder/reproducer. Vertical synchronization quality is maintained by recording on a channel capable of low frequency processing. Upon reproduction all synchronization, including mixing with supplemental video sources, is synchronized to the recorded master video synchronization and blanking signals. Video display at other than normal speeds is temporally synchronized from the slower tape speed. An X-Y monitor driven by vertical and horizontal sweep signals synchronized to the corresponding recorded synchronization signals generates a video presentation without repeated or omitted frames.
