Abstract:
1. A broadcast receiver comprising: a smart antenna configured to be disposed on an immobile object; a tuner, configured to extract a signal of predetermined channel from among airwaves received by the smart antenna; a signal processing unit, configured to process the signal extracted by the tuner; and a control unit, configured to: set a direction that the smart antenna is directed when the smart antenna fails to receive the airwaves as a reference direction; and rotate the smart antenna within a predetermined angle less than 90 degree from the reference direction until the smart antenna receives the airwaves in the following order; i) rotate in a first direction by a first angle from the reference direction; ii) rotate in a second direction which is opposite to the first direction by the first angle; iii) repeat ii) by the first angle from the reference direction; iv) rotate in the first direction in the first angle; v) repeat iv) by a second angle which is larger than the first angle from the reference position; vi) rotate in the second direction by the first angle; vii) repeat vi) by the second angle from the reference position; and viii) repeat vi) to vii) while increasing the second angle, wherein the second angle is no greater than 90 degrees.
