ABSTRACT:
A U-Matic video tape recorder of the type which is modified so as to employ wide-band-direct circuitry for developing a modulated signal from a video signal and to divide each frame of the modulated signal into several segments for recordation upon respective tracks of a tape is further modified to include circuitry for transporting the tape at a reduced rate wherein each segment of the modulated signal is multiply reproduced and circuitry for combining one of each multiply reproduced segments of a signal developed by a demodulator of the reproduced modulated signal with a black-level video signal to develop a signal representing in slow motion the original video signal.
