The present invention reduces the time required for an update process of reception-possible area information. A digital broadcast reception apparatus (300) comprises: a second reception unit (121) that receives a broadcast signal of a physical channel of a digital broadcast; a current position detection unit (125) that detects a current position; a current area determination unit (126) that determines, as a current area, an area to which the current position belongs; a channel scan control unit (123) that controls the second reception unit and determines whether the broadcast signal of the physical channel can be received; a broadcast area map storage unit (328) that stores reception-possible area information indicating areas where the physical channel can be received; and a broadcast area map generation unit (127) that, if the channel scan control unit determines that the broadcast signal of the physical channel can be received, derives, from the reception-possible area information stored in the broadcast area map storage unit, reception-possible area information of the current area and that performs, on the basis of the detected current position, an update process for updating the reception-possible area information of the current area. |
