An apparatus and a method for receiving two broadcast modes using one tuner in a Set-Top-Box (STB) are provided. The integrated tuner unit receives a broadcast signal of at least one of a DSG scheme and an OOB scheme to tune a desired broadcast band, and converts the broadcast signal into at least one Intermediate Frequency (IF) signal. The switching unit switches the at least one IF signal to at least one of the DSG demodulator and the OOB demodulator. The DSG demodulator demodulates the at least one IF signal according to the DSG scheme, when the broadcast signal of the DSG scheme is received. The OOB demodulator demodulates the at least one IF signal according to the OOB scheme, when the broadcast signal of the OOB scheme is received.
