Abstract
A system and method for facilitating infrared (IR) communications from a first device, such as a set top box, to a second device, such as a remote control, in the presence of an IR noise generating device, such as a plasma television, by using at least one of the first device and the second device to actively reduce a level of IR noise being generated by the IR noise generating device during an IR transmission from the first device to the second device.
