1. A triple deck recording and reproducing system, comprising:
- a digital tuner for processing received high frequency signals into video signals;
a plurality of driving mechanism means for recording said video signals onto and reproducing recorded signals from magnetic recording media;
switching means comprising a first switch for selectively supplying said recorded signals of a first one of said driving mechanism means to a second and a third one of said driving mechanism means, a second switch for selectively supplying said recorded signals of said second driving mechanism means to said first and said third driving mechanism means, and a third switch for selectively supplying said recorded signals of said third driving mechanism means to one of said first and said second driving mechanism means, said first to third switches being connected to output terminals of said driving mechanism means;
synchronizing signal detecting means for detecting synchronizing signals contained in said recorded signals reproduced from said plurality of driving mechanism means;
key inputting means provided with a plurality of function keys for enabling user control of said plurality of driving mechanism means and said switching means;
control means for generating control signals to control said plurality of driving mechanism means and said switching means according to user operation of said key inputting means; and
picture-in-picture signal generating means for controlling display of said recording signals based upon the existence or absence of the synchronizing signals.

Abstract
A triple deck recording and reproducing system with three video tape decks are integrated, and mounted within a single video tape recorder, when performing recording and reproducing, a main picture is displayed by selecting one among VHS or 8 mm or 4 mm of the video decks and another picture is displayed in the form of a PIP (Picture-In-Picture). Thus, the selected main and auxiliary pictures can be mixed with another deck for dubbing recording, and then, a user can display all the signals reproduced by three decks on the PIP, so as to compare the pictures with each other and display a plurality of the different pictures as a particular effect.
