Abstract:
1. A method comprising: detecting first infrared energy at a first time at an infrared (IR) signal detector of a device that is controllable by a remote control, wherein an infrared energy communication signal emitted from the remote control is absent in the detected first infrared energy; determining an amount of background ambient infrared energy based on the first infrared energy; determining a compensation based on the amount of background ambient infrared energy; detecting second infrared energy at a second time at the IR signal detector of the device, wherein the second time is after the first time, and wherein the detected second infrared energy includes at least the infrared energy communication signal communicated from the remote control; compensating the second infrared energy based on the determined compensation; and determining the infrared energy communication signal from the compensated second infrared energy.
