Abstract
In an apparatus for use with a video tape having a longitudinal track in which an address signal is recorded and successive slant tracks in which a video signal and an information signal are recorded at predetermined intervals; a magnetic head unit reproduces the video signal, the information signal, and the address signal. The information signal is applied to a pulse generator for generating a control pulse signal, and an address indication circuit provides an address indication in response to the address signal or the control pulse signal. A control circuit is provided for coupling one or the other of the address signal and the control pulse signal to the address indication circuit selectively in response to the speed of movement of the tape.
