Abstract : The present invention is directed to an apparatus and method for its use by which a master video signal is recored and reproduced in registry with other video signals, entailing no loss in synchronization upon reproduction irrespective of speed. Comparatively long term composite video signals are recorded on a multi-channel longitudinal tape recorder, with distinct channels of processed synchronization signals in spatial registry on the same tape. The comparatively low fundamental frequency of the vertical synchronization signal is precisely recorded and reproduced by FM processing. Spatial registry of video and synchronization signals on the longitudinal tape corresponds to perfect temporal registry upon reproduction.
