Broadcast receiving apparatus and broadcast receiving method

A broadcast receiving method comprising:

• converting received RF broadcast signals of a plurality of channels into intermediate frequency (IF) signals;
• processing and outputting the IF signals;
• changing at least one of the plurality of channels according to a user's input;
• generating a noise signal that has a signal level corresponding to a set signal level of an IF signal of the changed channel;
• and
• outputting the noise signal instead of the IF signal.

An apparatus which simultaneously receives a plurality of channels, the apparatus comprising:

• a radio frequency (RF) receiver which receives RF broadcast signals corresponding to the plurality of channels;
• an intermediate frequency (IF) converter which converts the received RF broadcast signals corresponding to the plurality of channels into respective IF signals;
• a plurality of signal processors which process and output 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 respective IF signals to be converted;
• and
• a controller which performs control of the noise generator to output the generated noise signal in place of the one of the respective IF signals during a time period in response to at least one of the plurality of channels being changed according to user's input.
