Abstract

Navigation techniques are provided. In one embodiment, an apparatus may include a receiver for receiving broadcast data including an update of traffic data, a decoder for extracting the update of the traffic data, a memory for storing standard traffic data, and a controller to generate traffic information based on the update of the traffic information and the standard traffic data.

Claims

1. A system comprising:

a content provider configured to provide multimedia content;

a traffic information source configured to provide traffic information; and

a broadcasting center configured to receive the traffic information to generate an update of the traffic information, and further configured to multiplex the multimedia content and the update of the traffic information to generate broadcasting data.

2. The system of claim 1, wherein the traffic information source is configured to provide the traffic information periodically.

3. The system of claim 1, wherein the broadcasting center is configured to generate the update of the traffic information based at least in part on a difference between previous traffic information and current traffic information.

4. The system of claim 1, further comprising a terminal configured to receive the broadcasting data.

5. The system of claim 4, wherein the terminal includes a receiving unit configured to decode the broadcasting data to restore the traffic information.

6. The system of claim 1, wherein the broadcasting data comprises a plurality of traffic events.

7. The system of claim 6, wherein the plurality of traffic events are encoded according to a TPEG (Transport Protocol Experts Group) standard.

8. The system of claim 7, wherein the plurality of traffic events comprise at least one of an accident, an obstruction, an activity, a moving hazard, a visibility or a weather condition.

9. The system of claim 4, wherein the terminal includes a display configured to display the traffic information.

10. The system of claim 4, wherein the terminal includes an input unit configured to receive a user input.

11. An apparatus comprising:

a receiver configured to receive a broadcast data including an updated part of traffic data;

a decoder configured to extract the updated part of the traffic data;

a memory configured to store standard traffic information; and

a controller configured to generate traffic information based at least in part on the updated part of the traffic data and the standard traffic information.

12. The apparatus of claim 11, further comprising:

a display configured to display the traffic information.

13. The apparatus of claim 11, wherein the receiver is configured to receive the updated part of the traffic data periodically.

14. The apparatus of claim 11, wherein the standard traffic information is categorized into a plurality of patterns according to a time period when the standard traffic information is used.

15. The apparatus of claim 14, wherein the updated part of the traffic data comprises a difference between previous traffic information and current traffic information.

16. The apparatus of claim 11, wherein the controller is configured to generate a rerouted path based on the traffic information.

17. The apparatus of claim 16, wherein the controller is configured to generate supplementary information based on the traffic data.

18. The apparatus of claim 17, wherein the supplementary information comprises at least one of a difference in TOA (Time of Arrival), a gap between the rerouted path and an original path, or a cause of change.

19. The apparatus of claim 18, wherein the display is configured to display the supplementary information.

20. The apparatus of claim 17, further comprising:

an input unit configured to receive a user input.

21. The apparatus of claim 20, wherein the controller is configured to re-route a path based on the user input.

22. The apparatus of claim 11, wherein the apparatus comprises a portable device.

23. The apparatus of claim 22, wherein the apparatus comprises a cellular phone.

25. The method of claim 23, further comprising:

receiving an input from a user to adjust the path.

26. The method of claim 25, wherein said receiving the updated part of the traffic information comprises receiving the updated part of the traffic information periodically.

27. The method of claim 25, wherein the standard traffic information is categorized into a plurality of patterns according to a time period when the standard traffic information is used.

28. The method of claim 27, wherein the updated part of the traffic information comprises a difference between previous traffic information and current traffic information.

29. The method of claim 25, further comprising:

generating supplementary information from the traffic information.

30. The method of claim 29, wherein the supplementary information comprises at least one of a difference in TOA (Time of Arrival), a gap between the rerouted path and an original path, or a cause of change.

31. The method of claim 30, wherein said displaying the rerouted path comprises displaying the supplementary information.

24. A method comprising:

receiving standard traffic information;

receiving an updated part of traffic information;

generating traffic data based on the updated part of the traffic information and the standard traffic information;

generating a rerouted path according to the traffic data; and

displaying the rerouted path.

32. A computer-readable storage medium having stored thereon computer instructions that, when executed by a computer, cause the computer to perform a method comprising:

retrieving standard traffic information from a memory;

receiving an updated part of traffic information;

generating traffic data based at least in part on the updated part of the traffic information and the standard traffic information; and

rerouting a path according to the traffic data.
