Abstract

A method and terminal for receiving and processing traffic information and a method and apparatus for providing the traffic information are disclosed. According to an embodiment, the method for receiving traffic information includes reading region information included in received traffic information, determining whether a first region indicated by the region information overlaps with a second region corresponding to location information on which traffic information is desired, and decoding the traffic information including the region information indicating the first region if the determination result indicates that the first and second regions overlap.

Claims

1. A method for receiving traffic information, the method comprising:

reading region information included in received traffic information;

determining whether a first region indicated by the region information overlaps with a second region corresponding to location information on which traffic information is desired; and

decoding the traffic information including the region information indicating the first region if the determination result indicates that the first and second regions overlap.

2. The method of claim 1, wherein the first and/or second region is obtained by using a minimum bounding rectangle (MBR) method or a minimum bounding radius method.

3. The method of claim 1, wherein the region information is included in a service component of the traffic information.

4. The method of claim 3, wherein the service component includes a congestion and travel time information (CTT) message.

5. The method of claim 3, wherein the region information is a minimum bounding rectangle (MBR) value corresponding to at least one link included in the service component.

6. The method of claim 1, wherein the location information on which traffic information is desired is a current location of a terminal for receiving the traffic information.

7. The method of claim 1, wherein the location information on which traffic information is desired includes a departure point and a destination point of a path.

8. A terminal for receiving traffic information, the terminal comprising:

a broadcast module configured to receive the traffic information;

a decoder configured to selectively decode the traffic information; and

a control unit configured to read region information from the traffic information received via the broadcast module, determine whether a first region indicated by the region information overlaps with a second region corresponding to location information on which traffic information is desired, and decode the traffic information including the region information indicating the first region if the determination result indicates that the first and second regions overlap.

9. The terminal of claim 8, wherein the first and/or second region is obtained by using a minimum bounding rectangle (MBR) method or a minimum bounding radius method.

10. The terminal of claim 8, wherein the region information is a minimum bounding rectangle (MBR) value corresponding to at least one link included in a service component.

11. The terminal of claim 8, further comprising a GPS module,

wherein the location information on which traffic information is desired is a current location acquired by using the GPS module.

12. The terminal of claim 8, further comprising an input unit,

wherein the location information on which traffic information is desired includes a departure point and a destination point of a path which are input through the input unit to search a path.

13. The terminal of claim 8, wherein the region information is included in a service component.

14. The terminal of claim 13, wherein the service component includes a congestion and travel time information (CTT) message.

15. A method for providing traffic information, the method comprising:

generating a traffic information message;

generating a service component including region information and at least one traffic information message; and

generating a transport frame including at least one service component.

16. The method of claim 15, wherein the region information identifies a region by using a minimum bounding rectangle (MBR) method or a minimum bounding radius method.

17. The method of claim 15, wherein the service component includes a congestion and travel time information (CTT) message.

18. The method of claim 17, wherein the region information includes a minimum bounding rectangle (MBR) value corresponding to at least one link included in the service component.

19. A data structure embodied on a computer-readable medium, comprising:

a service component including a field including at least one TPEG message, a field indicating an identifier for identifying the service component, a field indicating region information, and a field indicating a field length.

20. The data structure of claim 19, wherein the region information identifies a region by using a minimum bounding rectangle method or a minimum bounding radius method.
