A video processing system is described including a video processing device which generates a sequence of video display frames on a display unit under the control of a stored program, and a unique operation controlling device which is connected to the video processing device and which supplies signals in response to an operator's manipulation, to change the video data generated by the video processing device. The video processing device includes a replaceable program memory, first data receiving circuitry, a central processing unit, first data sending circuitry and a video signal generation circuitry. The operation controlling device may include various operation controlling buttons, switches, an operation member, rotor bodies, rotation detection mechanisms, counting circuitry, reset signal generation circuitry, second receiving circuitry, transfer circuitry and second sending circuitry. Advantageously, the operation controlling mechanism may be utilized to permit user control of a displayed object via said operation member and at the same time independently control movement of another displayed object via control switches protruding from the operation controlling mechanism housing.
