Abstract
The universal remote control system includes a computer having a memory and code data for creating appropriate IR lamp driver instructions for causing an infrared signal generator to emit infrared signals which will cause specific functions to occur in a specific controlled device, for operating a variety of devices to be controlled, stored in the memory of the computer. The system further includes a universal remote control comprising: input circuitry including a set of keys or pushbuttons for inputting commands into the remote control, infrared signal output circuitry including IR lamp driver circuitry for supplying an infrared signal to a controlled device, a central processing unit (CPU) coupled to the input circuitry and to the signal output circuitry, a memory coupled to the CPU, and data coupling circuitry and structure for periodically coupling the computer to the remote control for inputting from the computer memory appropriate IR lamp driver instructions for causing the infrared signal output circuitry to emit infrared signals which will cause specific functions to occur in a specific controlled device, for operating a variety of devices to be controlled into the memory o…
