The ability to operate remote control transmitter functions from external sensors, in conjunction with internal or external controls, to provide condition dependant automatic control of devices such as digital video recorders and the like are presented. The system enables any remote control transmitter to be modified to perform this function without the need to redesign any existing control functions either in the transmitter or receiver and is compatible with all remote control transmitters and receiver functions. The system is applicable to any form of control, is not dependant on existing designs, and easily implemented in any remote control transmitter. The system is a cost-effective solution to any problem, or requirement, associated with external control of remote control functions.
