Abstract:
An object of the present invention is to provide a digital broadcast reception apparatus that allows a stable viewing even if a reception environment changes along with a movement. In the present invention, based on current position information indicating a current position detected by a current position detection section and broadcast area information stored in a broadcast area information storage section, a search-mode switching control section instructs a tuning control section to select a diversity operation mode if the current position is close to a boundary of a broadcast area, and select an independent reception operation mode if the current position is not close to the boundary of the broadcast area. In the diversity operation mode, a first system and a second system are tuned to the same physical channel, and cooperate with each other to demodulate a digital broadcast signal and a make an output through a diversity process. In the independent reception operation mode, the first system and the second system individually and independently demodulate the digital broadcast signal and make an output.
