PROJECTOR WITH POWER LINE COMMUNICATION FUNCTION

摘要

A projector with a function of high speed PLC(Power Line Communication) is provided to enhance user's convenience with no additional data line and wire by receiving an image from a computer through a power line and projecting the received image. A projector with a high speed PLC function comprises a coupler(410), a PLC unit(420), and a projection processing unit(430). The coupler is connected to a power line(PL) to detect a PLC signal transmitted from the power line. The PLC unit(420) recovers the PLC signal from the coupler. The projection processing unit projects an image transmitted from a computer(20) to be included in PLC data of the PLC unit.
