BROADCAST RECEIVER
First Claim
1. A broadcast receiver comprising:
- a receiving unit for receiving a broadcast wave sent out from a sending-out station;
a position acquiring unit for acquiring position information about a position of a moving object in which said broadcast receiver is mounted;
a broadcast display state acquiring unit for acquiring broadcast display state information showing a display state of the broadcast wave received by said receiving unit every time said moving object travels a distance;
a storage unit for storing history information about switching between sending-out stations, the history information including the broadcast display state information, while bringing the history information into correspondence with the position information about the position of said moving object;
an extracting unit for extracting history information from said storage unit;
a determining unit for comparing current broadcast display state information acquired at a current position of said moving object with broadcast display state information in history information which is extracted from said storage unit by said extracting unit and which corresponds to a position which is same as the current position to determine that a sending-out station corresponding to history information which provides a display state which is same as a display state of a broadcast wave currently being received as said moving object travels is a switching destination; and
a switching unit for changing the sending-out station from which to receive the broadcast wave by using said receiving unit according to a switching command from said determining unit.

Abstract
A broadcast receiver stores history information about switching between sending-out stations, the history information including broadcast display state information, in a storage unit 7 while bringing the history information into correspondence with position information about a position of a vehicle, and compares current broadcast display state information acquired at a current position of the vehicle with broadcast display state information in history information which is extracted from the storage unit 7 and which corresponds to a position which is the same as the current position to determine that a sending-out station corresponding to history information which provides a display state which is the same as the display state of a broadcast wave currently being received as the vehicle travels is a switching destination.
