PROBLEM TO BE SOLVED: To provide a broadcast system capable of setting a frequency at which reception status is satisfactory, even if a vehicle equipped with an on-vehicle receiver moves. SOLUTION: When the vehicle travels out of the broadcast area of a received broadcast station and the reception status of a broadcast program is worsened, a network station list requesting section 15 requests a center 20 for a network station list, and the center 20 extracts broadcast stations in the same network to create the network station list. A reception status management section 16 extracts a broadcast station from the list, and a receiving station changing section 17 changes the broadcast station to be received by a broadcast receiving section 11 to the broadcast station extracted by the section 16. As explained above, the center 20 manages the information of the network station to which a broadcast station belongs and the information of a broadcast area, thereby enabling the on-vehicle device to always set a broadcast based on the latest information only by changing the information of the center 20 when the information changes.
