Broadcast receiving apparatus and broadcast receiving method

摘要

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.

1. A broadcast receiving apparatus comprising:
an intermediate frequency (IF) converter which converts received RF broadcast signals of a plurality of channels into IF signals, respectively; a signal processor which processes and outputs the converted IF signals; a noise generator which generates a noise signal that has a signal level corresponding to a set signal level of one of the IF signals to be converted; and a controller which performs control to output the generated noise signal in place of the one of the IF signals during a time period in response to at least one of the plurality of channels being changed according to user's input.
