Abstract:
A digital broadcasting reception apparatus (100) is provided with: reception units (111, 121) that receive signals; signal-intensity detection units (112, 122) that detect the reception intensity of the received signals; a channel-scan control unit (125) that detects receivable physical channels; an area map storage unit (129) that stores coverage area information indicating coverage areas; a current-position detection unit (127) that detects the current position; a tuning control unit (118) that determines a distance threshold value on the basis of the reception intensity detected by the signal intensity detection units when the channel-scan control unit (125) detects a physical channel and the detected current position is not included within the coverage area of the detected physical channel; and an area map generating unit (128) that expands the coverage area on the basis of the determined distance threshold value.
