RF SWITCH MODULE AND TV BROADCASTING RECEIVING APPARATUS

摘要

An RF(Radio Frequency) switch module and a television broadcasting receiving apparatus are provided to detect a remote control signal from a television link to receive an IR(Infrared Rays) signal at a remote place through a cable. An RF(Radio Frequency) switch module(100) comprises the followings: a first switch(110) for turning on/off an RF input signal; a second switch(120) for selecting or intercepting an RF modulation signal by being turned on/off to be opposite to the on/off switching operations of the first switch; a distributor(130) for respectively distributing an RF signal, selected by the first and second switches, to first and second RF output signals; and a television link receiver(140) which supplies television link operation power to a television link and receives a remote control signal from the television link.
