[origin: WO9930497A1] An interactive control module for use with an interactive cable television system. The module includes a frame having a television signal output, an interactive controller, a scrambled video provider and a modulator. The interactive controller is mounted to the frame. The scrambled video provider is also mounted to the frame and is connected to receive an information signal from said interactive controller. The scrambled video provider converts the information signal into a scrambled television signal. The modulator is mounted to the frame and is connected to receive the scrambled television signal so as to provide a modulated scrambled television signal to the television signal output.
