摘要：A broadcast receiver includes a smart antenna, a tuner which extracts a signal ofpredetermined channel from among airwaves received by the smart antenna, a signalprocessing unit which processes the signal extracted by the tuner, and a control unit, in a
case the airwave has become unreceivable, to set a pointing direction of the antenna onthat occasion as a reference direction, to shift the pointing direction a predeterminedmagnitude counterclockwise or clockwise, and to decide propriety of reception of theairwave. The control unit iterates counterclockwise and clockwise shifts alternately in aregion near the reference direction, while the shift magnitude of the pointing direction isbeing increased in succession and so that the direction as to which the propriety ofreception has been decided once may not be included in the directions of the shifts, untilthe reception of the airwave becomes possible.
