1. A system for remotely controlling a video tape recorder which performs different functions including a timer activated recording function as a first function, and second function, comprising;

  • a controller provided in said video tape recorder for controlling operation of said video tape recorder and selecting operation modes for accomplishing different functions to according to a control command;

    first means, incorporated in said apparatus and associated with said controller for performing said first function;

    second means, incorporated in said apparatus and associated with said controller for performing said second function;

    a remote control commander including a push button for selecting operation modes of said apparatus and producing a remote control signal carrying said control command, a rotary dial assembly operable for generating said control command for operating said first and second means selectively for performing said first and second functions;

    a mode selector switch for selecting an operation mode of said remote control commander at least among a first position, at which said control command generated by said remote control commander operates said first means for performing said first function, and a second position, at which said control command generated by said remote control command operates said second means for performing said second function;

    said rotary dial assembly comprising;

    a dial manually rotatable at a desired speed in opposing first and second directions;

    a first sensing means for monitoring magnitude of angular displacement of said dial and producing a rotation angle indicative signal;

    a timer set mode switch manually operable to produce a timer set mode selector signal ordering said video tape recorder system to operate in a timer set mode;

    a display for displaying at least symbols representing a timer-activated recording start timing and end timing; and

    a controller responsive to said timer set mode selector signal for changing the value represented by each of said symbols at a given rate on said display, said given rate being selected on the basis of the values of said direction indicative signal and said rotating angle indicative signal.
