Abstract
A digital broadcast reception device mounted on a mobile body includes a position information detection unit for detecting the position of the digital broadcast reception device, a database holding unit for storing reception quality of the digital broadcast in advance, a switching point calculation unit for obtaining a hierarchy switching point, and output switching unit for performing a hierarchy switching. The digital broadcast reception device acquires the hierarchy switching frequency generated during movement in advance based on reception quality information previously stored in the database holding unit, and controls the hierarchy switching so as to reduce the switching frequency, thereby reducing disconnections of video and audio.
