PURPOSE: A tuner and television including a radio transmitter/receiver and a transmitting/receiving method of the tuner and television are provided to separate a tuner from a television system. CONSTITUTION: A tuner(100) includes an adaptor(110), a tuner module(120), a demodulator(130), a tuner antenna(140), a tuner transmitter(150), a tuner receiver(160), and an amplifier(170). The tuner module converts an RF signal received from the antenna into an IF signal. The demodulator demodulates the IF signal output from the tuner module into an AC signal. The tuner antenna transmits and receives radio signals. The tuner transmitter modulates the AV signal and transmits the modulated signal through the tuner antenna. The tuner receiver demodulates a channel control signal received from a television system(200) through the tuner antenna. The amplifier amplifies the channel control signal to allow the tuner module to tune a channel. The television system includes a TV antenna(210), a television receiver(220), and a television transmitter(230). |
