PURPOSE: A device for receiving broadcast of two kinds of modes with one tuner and a method thereof are provided to reduce power consumption by using the tuner in a set top box, and to reduce manufacturing costs of products. CONSTITUTION: An integrated tuner unit(200) receives a broadcast signal of an OOB(Out-Of-Band) mode or a DSG(DOCSIS Set-top Gateway) mode. The integrated tuner units tune a desired broadcasting band. The integrated tuner unit converts the tuned broadcasting signal to an IF(Intermediate Frequency) signal. An IF switching unit converts an IF signal into a demodulator. A DSG demodulator(202) demodulates the IF signal to the DSG mode.
