Abstract

A method for providing traffic information. The method includes providing information including an object of a first type having a file including the traffic information and an object of a second type including information about the file and information about a service provider providing the file.

Claims

1. A method for providing traffic information to a traffic information receiving apparatus, the method comprising:

providing information to a receiving unit including an object of a first type having a file including the traffic information and an object of a second type including information about the file and information about a traffic information service providing the file;

extracting information via a first decoder about a traffic information service and information about each file from a received object of the second type; and

determining a decodability of the traffic information embedded in each file via a second decoder based on the extracted information about the traffic information service.

2. The method of claim 1, wherein the object of the first type includes a header core, a header extension and a body that encapsulates the file, and the object of the second type includes a directory extension containing at least one parameter and directory entries including a MOT header that is a duplicate of the header core and the header extension in the object of the first type.

3. The method of claim 2, wherein the directory extension contains a parameter identifying version information about the traffic information service, synch information specifying a time for synchronizing traffic information and a type information indicating a type of the file.

4. The method of claim 3, wherein the type information indicates whether the file is a binary data file or a markup language data file.

5. The method of claim 2, wherein the header extension of the MOT header contains a first parameter identifying version information of a transmitter side that transmitted the file and a second parameter indicating that the identifying version information exist in the first parameter.

6. The method of claim 1, wherein a number of directory entries corresponds to a number of objects of the first type.

7. The method of claim 1, wherein a filename of the file includes an identification assigned to the traffic information service providing the traffic information, a service component identifier, a file number and delimiters.

8. The method of claim 1, further comprising:

organizing the object of the first type and the object of the second type in a single object and transmitting the single object to a navigation reception terminal.

9. The method of claim 1, further comprising:

receiving the provided information via a navigation reception terminal; and

extracting the file, the information about the file and the information about the traffic information service providing the file.

10. The method of claim 9, further comprising:

determining how the file is to be decoded;

decoding the file based on the determining step; and

providing the decoded information contained in the file to a user of the navigation reception terminal.

11. The method of claim 1, further comprising:

determining whether each file from among the extracted files is either to be decoded for utilizing traffic information or to be used for updating traffic information based on the extracted information about each file.

12. An apparatus for receiving traffic information, the apparatus comprising:

a receiving unit configured to received information including an object of a first type having a file including the traffic information and an object of a second type including information about the file and information about a traffic information service providing the file;

a first decoder configured to extract the file from the object of the first type, and the information about the file and the information about the traffic information service from the object of the second type; and

a second decoder configured to determine a decodability of the traffic information of the file based on the extracted information about the traffic information service.

13. The apparatus of claim 12, wherein the object of the first type includes a header core, a header extension and a body that encapsulates the file, and the object of the second type includes a directory extension containing at least one parameter and directory entries including a MOT header that is a duplicate of the header core and the header extension in the object of the first type.

14. The apparatus of claim 13, wherein the header extension of the MOT header contains a first parameter identifying version information of a transmitter side that transmitted the file and a second parameter indicating that the identifying version information exist in the first parameter.

15. The apparatus of claim 12, wherein a number of directory entries corresponds to a number of objects of the first type.

16. The apparatus of claim 15, wherein the directory extension contains a parameter identifying version information about the traffic information service, synch information specifying a time for synchronizing traffic information and a type information indicating a type of the file.

17. The apparatus of claim 16, wherein the type information indicates whether the file is a binary data file or a markup language data file.

18. The apparatus of claim 12, wherein a filename of the file includes an identification assigned to the traffic information service providing the traffic information, a service component identifier, a file number and delimiters.

19. The apparatus of claim 12, further comprising:

a location detector configured to obtain information about a current location of the apparatus; and

a navigation engine configured to store the extracted traffic information and to display a part of the traffic information corresponding to road segments belonging to a particular region around the obtained current location.

20. The apparatus of claim 12, wherein the second decoder is further configured to determine whether the file is to be used for providing traffic information or used for updating traffic information.
