ABSTRACT:
A multifunctional control device and method is used to determine a head channel selecting signal for playback heads of a video tape recorder and for controlling a phase shift direction of a video signal according to a desired reproduction mode. The video tape recorder has four heads, a first pair for use during standard play and a second pair for use during super long play. The heads read out recorded video signals and a first switch is connected to the first pair of heads and a second switch is connected to the second pair of heads for selectively providing outputs to corresponding amplifiers, under control of a servo controller. A third switch is connected to the outputs of the amplifiers for providing outputs under control of a microcomputer. The microcomputer controls the servo controller which in turn controls the speed of a drum motor and a capstan motor. The microcomputer also provides a phase shift direction controlling signal. An output of the servo controller is provided to the microcomputer along with an output of a comparator comparing the outputs of the amplifiers.
