The server 200 generates broadcast area information including even information on which one of a one-segment broadcast and a full-segment broadcast can be received in accordance with a vehicle height in addition to information on which broadcast station channel can be received, for each digital broadcast receivable area. Thus, an optimum reception channel by which a full-segment broadcast is received as much as possible can be selected in accordance with a vehicle present position and a vehicle height. |
