Abstract
A video signal frame search apparatus for selecting a frame from a video signal recorded on a magnetic tape, e.g. for supplying the frame to a video printer, is based on a system controller which controls playback and rewind operations of a VTR during a frame search operation. When a desired frame is displayed during such a frame search operation, actuation of a switch by the user causes a plurality of frames adjcent to and including the desired frame to be stored in a memory and then displayed simultaneously, enabling the user to specify to the system controller the precise position of the desired frame.
