Abstract
Methods and systems for relaying an optical signal from a remote control to a remote-controlled device such as a home entertainment device or a security device. Embodiments include at least one optical receiver and a plurality of optical transmitters. The optical transmitter positioned with an unobstructed line-of-sight to the home entertainment device is identified and the data encoded in the optical signal from the remote control is sent to that transmitter. A second optical signal that is substantially identical to the first is then generated at the optical transmitter and communicated to the home entertainment device.
