Patent ID: 7174140

Claim:
An RF system in a multimedia receiver including a plurality of antennas and a digital tuner and demodulator unit, the RF system comprising: a plurality of RF input terminals each connected to a corresponding one of the plurality of antennas; an RF relay for selectively outputting an RF signal input to one of the plurality of RF input terminals on the basis of control signals; an RF amplifier for amplifying an RF signal output from the RF relay; an RF signal distributor comprising a first RF signal distributor and a second RF signal distributor for distributing the RF signal amplified and output from the RF amplifier to produce a plurality distributed RF signals, wherein the digital tuner and demodulator unit receives one of the plurality of distributed RF signals and produces an output signal; an RF modulator for receiving and modulating the output signal from the digital tuner and demodulator unit to produce an RF signal as output; an RF selection switch for selectively outputting at least one of the other distributed RF signals output from the RF signal distributor and the RF signal output from the RF modulator on the basis of a control signal; and an RF output terminal for outputting the signal selectively output from the RF selection switch.
