APPARATUS AND METHOD FOR SWITCHING RF SIGNAL ACCORDING TO HYBRID SWITCHING SCHEME AND BROADCAST RECEIVING APPARATUS USING THE SAME

摘要

An RF signal switching device using the hybrid switching method, a method thereof and a broadcasting receiver using the same are provided to enhance the Isolation property by arranging a plurality of switching elements on a path through which a broadcast signal is transmitted in the hybrid type. An RF signal switching device using the hybrid switching method comprises the followings. An air input unit(110) receives an airwave broadcast signal received through the air, and then transmits it to an air switching unit(120). The air switching unit passes or blocks the airwave broadcast signal. A cable input unit(130) receives a cable broadcasting signal received through a cable, and then transmits it to a cable switching unit(140). The cable switching unit performs a switching operation to pass or block the cable broadcasting signal. A tuner switching unit(150) performs a switching operation to pass or block one of the airwave broadcast signal and cable broadcasting signal.
