Abstract: A broadcast receiving apparatus is provided, which includes an input that receives input signals, a signal processing unit which amplifies only a signal in a band that corresponds to a selected channel from among the input signals, and automatic gain controls with a first sensitivity so that the amplified signal maintains a preset level value, and then outputs the result, a demodulator which demodulates the signals output from the signal processing unit into digital transport stream signals, a controller configured to control the signal processing unit so that the signal is automatic gain controlled with a second sensitivity less sensitive than the first sensitivity, when the selected channel is an ultra high frequency (UHF) range signal.
