`ABSTRACT
`The universal remote control system includes a com(cid:173)
`puter having a memory and code data for creating ap(cid:173)
`propriate IR lamp driver instructions for causing an
`infrared signal generator to emit infrared signals which
`will cause specific functions to occur in a specific con(cid:173)
`trolled 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 com(cid:173)
`prising: input circuitry including a set of keys or push(cid:173)
`buttons for inputting commands into the remote con(cid:173)
`trol, infrared signal output circuitry including IR lamp
`driver circuitry for supplying an infrared signal to a
`controlled device, a central processing unit (CPU) cou(cid:173)
`pled to the input circuitry and to the signal output cir(cid:173)
`cuitry, a memory coupled to the CPU, and data cou(cid:173)
`pling circuitry and structure for periodically coupling
`the computer to the remote control for inputting from
`the computer memory appropriate IR lamp driver in(cid:173)
`structions for causing the infrared signal output cir(cid:173)
`cuitry 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 of the remote control to enable the remote
`control to control various devices to be controlled upon
`the inputting of commands to the keys of the input
`circuitry.
