Abstract
A digital television broadcast signal receiver connected to a multi-directional antenna carries out in advance automatic scanning for each channel to determine and store the strength of a signal received in each of multiple receiving directions of the antenna, a best receiving direction, and a maximum value of the received signal strengths, normalize the received signal strengths measured in the respective directions with respect to the maximum received signal strength, and produce and store an antenna direction level pattern including a bar graph that shows the received signal strengths in the respective directions with the normalized values used as the amplitude. In response to a command from a user, the receiver superimposes the level pattern on a video image being received for display on a display screen, so that a user can select a receiving direction on the screen. When image degradation takes place during signal reception by the antenna having been already adjusted in orientation, a user can manually reorient the antenna so as to quickly improve the receiving condition without the need for additional time-consuming automatic scanning for adjustment of the orientation of the antenna.
