<p>PURPOSE:To control slow, still and frame feeding operations performed independent of an operator with a simple circuit in a digital VTR. CONSTITUTION:When slow, still and frame feeding reproducing is performed, a track number in a track is detected by a signal processing circuit and frame discontinuing spots on a magnetic tape 1 are detected by using a timing detection control circuit 31 having a flip flop for holding track numbers within a specified period of time. The operation of a capstan motor 2 is controlled by sending this signal to the mode control circuit 12 of a servo circuit, the stilled condition of the capstan motor 2 is reported to the signal processing circuit by the servo circuit and the signal processing circuit is controlled. Thus, the signal processing circuit and the servo circuit are synchronized at the time of slow and still reproducing and simpe slow, still and frame feeding reproducing is performed.</p> |
