ABSTRACT:
A control system is provided which is capable of controlling the speed of a video tape recorder in a continuously variable manner, even though the video tape recorder is designed to operate at discrete speeds. The variable speed control is achieved without any need to modify the discrete speed video tape recorder. The control system of the invention selects two of the discrete speeds of the video tape recorder, and then switches between the two speeds at a rate determined by the setting of a variable speed control, so as to enable the video tape recorder to operate at variable speeds between the lower and the higher of the selected discrete speeds, and depending upon the setting of the variable speed control.
