A system for retrievably providing a video display of a pictorial information message on a video display device from video information stored, such as on a video tape, in a plurality of frames, unique pictorial information being stored in each frame for display thereof in response to a request therefor, the frames each including a plurality of segments with one displayable pictorial information message being contained in each segment, the selected segment being retrievable for individual display of only this requested pictorial information containing frame segment. The video tape storage media in addition to the video track upon which the pictorial information is stored, contains an audio track having unique frame identification code information stored thereon for providing a frame location signal which is utilized to retrieve the frame. The frame segment is retrieved by preferably counting horizontal sync pulses to determine the proper location of the requested frame segment within the displayable frame video signal. A masking generator is utilized together with a gating network to mask out all portions of the displayable video frame signal other than the frame segment portion containing the requested pictorial information. The pictorial information may preferably be signatures associated with unique account numbers, such as bank accounts, to enable verification of an externally provided signature for the associated account number and, in conjunction with associated data processing means, a selected transaction associated with this account may occur substantially simultaneously with the video display of the signature for verification.
