Abstract: Provided are a broadcast receiving apparatus which simultaneously receives a plurality of channels using a single tuner and tunes to a channel without affecting other channels when changing a channel, and a broadcast receiving method thereof. The broadcast receiving apparatus includes a radio frequency (RF) receiver receiving RF broadcast signals of a plurality of channels; an intermediate frequency (IF) converter converting the RF broadcast signals of the plurality of channels into IF signals, respectively; a plurality of signal processors separately processing and outputting the converted IF signals; a noise generator generating a noise signal corresponding to the IF signals; and a controller performing control to output the noise signal instead of the IF signals when at least one of the plurality of channels is changed according to user's input.
