ABSTRACT:
A jammer for an infrared remote control temporarily disables the remote control by transmitting an infrared pulse pattern similar to the pulse pattern of the remote control at approximately the same frequency but at a different pulse pattern, thereby confusing the detection circuitry of the receiving device, such as a television remote control receiver. The circuitry of the jammer preferably includes a timer for reducing battery power consumption by triggering a second timer on the transmitter to emit pulses only periodically.
