1. An information presentation device to be installed in or carried by a movable entity, comprising:
- a receiving unit for acquiring data related to facilities by receiving a broadcast providing a data distribution service from a broadcast station;
a primary database storing unit for storing a primary database in which the data acquired by the receiving unit are registered;
a database update processing unit for updating content in the primary database with data acquired by the receiving unit every time the receiving unit acquires data;
a travel distance detection unit for detecting that the movable entity has traveled a predetermined distance;
a position detection unit for detecting a position of the movable entity;
a secondary-data extraction processing unit for extracting, from the primary database, data related to facilities near the position of the movable entity detected by the position detection unit at each time point when the travel distance detection unit detects that the movable entity has traveled the predetermined distance;
a secondary database storing unit for storing a secondary database in which the data extracted by the secondary-data extraction processing unit are registered;
a presentation-data extraction processing unit for extracting data for presentation from the data registered in the secondary database; and
a presentation unit for presenting the data extracted by the presentation-data extraction processing unit to a user.

Abstract
There is provided a device that receives a broadcast providing a data distribution service from a broadcast station, registers data related to facilities acquired through the data distribution service in a primary database, extracts from the primary database data related to facilities near the position of the host vehicle every time a host vehicle has run a predetermined distance, registers the extracted data in a secondary database, and presents data for presentation extracted from the secondary database to a user.

9. A navigation device to be installed in or carried by a movable entity, comprising:
-
a receiving unit for acquiring data related to facilities by receiving a broadcast providing a data distribution service from a broadcast station; a primary database storing unit for storing a primary database in which the data acquired by the receiving unit are recorded; a database update processing unit for updating content in the primary database with data acquired by the receiving unit every time the receiving unit acquires data; a position detection unit for detecting a position of the movable entity; a destination setting unit for setting a destination of the movable entity; a route searching unit for searching a guide route for the movable entity based on the position of the movable entity detected by the position detection unit, the destination set by the destination setting unit, and map data acquired from a map data storing unit; a secondary-data extraction processing unit for extracting, from the primary database, data related to facilities located along the guide route searched by the route searching unit; a secondary database storing unit for storing a secondary database in which the data extracted by the secondary-data extraction processing unit are registered; a presentation-data extraction processing unit for extracting data for presentation from the data registered in the secondary database; and a presentation unit for presenting the data extracted by the presentation-data extraction processing unit to a user. - View Dependent Claims (10, 11, 12)
