Abstract

A navigation data provision system comprises:

a broadcasting business facility for the dissemination of broadcast data that, at the least, includes drive plan data;

a navigation business facility which selects, from the drive plan data, at least one set of drive plan data that matches user preference data; and

a navigation terminal which receives the drive plan data and which employs the drive plan data to help prepare a route guide for a vehicle.

Claims

1. A navigation data provision system comprising:

a broadcasting business facility for the dissemination of broadcast data that, at the least, includes drive plan data;

a navigation business facility which selects, from said drive plan data, at least one set of drive plan data that matches user preference data; and

a navigation terminal which receives said drive plan data and which employs said drive plan data to help prepare a route guide for a vehicle,

wherein said broadcasting business facility includes

broadcaster which broadcasts multiple sets of drive plan data as broadcast waves, and

transmitter which transmits said multiple sets of drive plan data along a predetermined communication line,

wherein said navigation business facility includes

receptor which receives said multiple drive plan data from said broadcasting business facility along said predetermined communication line,

preference data accumulator which stores preference data for a user,

selector which employs said preference data to select at least one of said multiple sets of drive plan data, and

transmitter which transmits, to said navigation terminal, a reception channel for said selected drive plan data, and

wherein said navigation terminal includes

channel setter which sets a reception channel for said navigation terminal to serve as said reception channel for said drive plan data selected by said navigation business facility,

extractor which extracts destination data from said drive plan data received at said reception channel, and

a route setting processor which uses said destination data that is extracted to perform a route setting process.

2. The navigation data provision system according to claim 1, wherein

multiple sets of drive plan data, each of which include data for guiding users to sightseeing spots and positioning data therefor, are provided by said broadcasting business facility, and wherein

said extractor of said navigation terminal extracts said position data.

3. The navigation data provision system according to claim 1, wherein

said drive plan data are prepared and are provided to said broadcasting business facility by said navigation business facility.

4. A navigation server comprising:

receptor which receives drive plan data from a broadcasting business facility that transmits broadcast data, including said drive plan data;

preference data accumulator which accumulates preference data for a user;

selector which employs said preference data to select at least one set of said multiple drive plan data; and

transmitter which transmits to a navigation terminal a reception channel for said selected drive plan data.

5. The navigation server according to claim 4, further comprising:

preparation member which prepares said drive plan data; and

provider which provides said prepared drive plan data for said broadcasting business facility.

6. A navigation terminal comprising:

channel setter which sets a reception channel for said navigation terminal based on reception channel data received from a navigation business facility;

extractor which extracts destination data from drive plan data that are received through said reception channel;

a route setting unit which performs a route setting process by using said extracted destination data.
