BROADCAST RECEIVING SYSTEM USING HIGH-SPEED POWER LINE COMMUNICATION, CONCERNED WITH TRANSMITTING BROADCASTING SIGNAL THROUGH POWER LINE WHICH SUPPLIES POWER TO RECEIVER

摘要

PURPOSE: A broadcast receiving system using high-speed PLC(Power Line Communication) is provided to transmit a broadcasting signal with power through a power line, so that a receiver can reproduce a video or a voice by detecting the broadcasting signal transmitted with the power, thereby reducing wires of the system. CONSTITUTION: A repeater(32) receives a broadcasting signal from a broadcasting signal source(31), modulates the broadcasting signal such that the modulated broadcasting signal can be transmitted without signal loss or signal distortion through a power line(33), and outputs the modulated broadcasting signal to the power line(33). The power line(33) transmits the outputted broadcasting signal with a common AC power. A receiver(34) receives the power and the broadcasting signal from the power line(33), demodulates the broadcasting signal, and reproduces a video and a voice.
