ABSTRACT:
A VTR is responsive to designation of an index scan mode for detecting an index signal recorded on a control track of a tape with the tape being traveled at high speed. During high-speed traveling, a video signal received by a contained tuner is outputted and applied to a monitor receiver. Every time the index signal is detected, the starting portion of each recorded program is reproduced in a normal reproducing mode during a short time period and time-base compressed, to be combined with the above described received video signal. The combined video signal for picture-in-picture display is applied to the monitor receiver externally provided, so that a received video signal is displayed on a main screen while a reproduced video signal is displayed on a subscreen. When a short time period elapsed, PIP control is cancelled, so that a high-speed traveling mode is established until the next index signal is detected. When a user turns an operation mode setting switch on, the contents recorded on the tape can be monitored in various desired modes so long as the operation mode setting switch is turned on, irrespective of the mode.
