Abstract
A broadcast receiver includes a smart antenna, a tuner for extracting a signal of a predetermined channel from airwaves received by the smart antenna, a signal processing unit for processing the signal extracted by this tuner, and a control unit for controlling the smart antenna. The control unit detects a receivable direction by performing automatic scanning for each of the channels with respect to each of the directions of the smart antenna, and when the receivable direction is first detected during execution of automatic scanning for a certain channel, the automatic scanning is stopped at a point in time of the detection and transition to automatic scanning for the next channel is made.
