Abstract
Disclosed herein are a broadcast signal retransmission system and method using illuminating visible-light communication. The broadcast signal retransmission system comprises one or more light-emitting diode (LED) lighting fixtures, one or more smart communicators, and a home server. The home server receives and demodulates a multi-channel broadcast signal and, in reply to a signal request message from a smart communicator, transmits a demodulated broadcast channel signal through a power line to an LED lighting fixture indicated by the signal request message. The LED lighting fixture converts the broadcast channel signal into a light signal. The smart communicator receives the light signal from the LED lighting fixture and decodes the light signal into a broadcast signal. As a result, the user can selectively receive a broadcast signal of a desired channel using a smart communicator via a nearby LED lighting fixture.
