<p>Disclosed are a broadcasting signal receiving apparatus and a control method thereof. The broadcasting signal receiving apparatus comprises: a signal receiver which receives a broadcasting signal comprising at least one future extension frame; a signal sensor which senses a level of the received broadcasting signal; an automatic gain controller which performs automatic gain control to make the broadcasting signal have a certain level according to the sensed level of the broadcasting signal; and a control signal generator which generates a control signal to apply the automatic gain control to the broadcasting signal according to whether the broadcasting signal is in the future extension frame. With this, the AGC is performed according to whether it is the future extension frame or not, thereby preventing the signal from distortion, real-time controlling the AGC to be performed or frozen, and improving adjacent channel interference rate characteristics.</p> |
