Abstract

Encoding and decoding of application information is disclosed. An encoding method includes creates multimedia object information on video and/or audio data related to content carried by a traffic information message provided through traffic information service, creates reference information indicating the traffic information message, and organizes a multimedia information message that includes the multimedia object information and the reference information. While using a traffic information provided by a traffic information service, a user can, if necessary, recognize visually and/or audially a special traffic situation of which information is provided by a traffic information service.

Claims

1. A method for encoding information, comprising:

creating multimedia object information about data of video and/or audio attribute associated with content carried by a first information message provided through a traffic information service;

creating reference information indicating the first information message; and

organizing a second information message including the created multimedia object information and the created reference information.

2. The method of claim 1, wherein the reference information comprises a service component identifier assigned for indicating conveyance of information related to the traffic information service, an identifier of the first information message, and a version number of the first information message.

3. The method of claim 1, wherein the second information message is provided through a multimedia information service different from the traffic information service.

4. The method of claim 3, further comprising

inserting into the first information message a service component identifier assigned for indicating conveyance of information related to the multimedia information service, an identifier of the second information message, and a version number of the second information message.

5. The method of claim 1, wherein, if an additional information message is associated with the data of video and/or audio attribute besides the first information message, the creating of the reference information creates a plurality of pieces of reference information with respect to the associated information messages.

6. The method of claim 1, wherein the reference information is recorded in an area of management information of the second information message.

7. The method of claim 1, wherein the reference information is recorded in one of components that follow management information of the second information message.

8. The method of claim 1, wherein the multimedia object information includes the data of video and/or audio attribute.

9. The method of claim 1, wherein the multimedia object information includes information for accessing the data of video and/or audio attribute transmitted through a signal channel or a transmission medium different from a signal channel or a transmission medium through which the second information message is transmitted.

10. The method of claim 9, wherein the information for accessing includes frequency information.

11. The method of claim 10, wherein the information for accessing further includes information about a manner in which the data of video and/or audio attribute is transferred.

12. The method of claim 9, wherein the information for accessing includes unique location information on a network about the data of video and/or audio attribute.

13. The method of claim 1, wherein the multimedia object information includes at least one of play type, encoding format, size, collector information, and description information of the data of video and/or audio attribute.

14. A method for decoding information, comprising:

extracting from a signal for a multimedia information service a first information message carrying multimedia object information about data of video and/or audio attribute;

extracting reference information from the extracted first information message; and

extracting traffic information associated with the data of video and/or audio attribute from a second information message provided through a traffic information service distinguished from the multimedia information service, the second information message being identified by the extracted reference information.

15. The method of claim 14, wherein the reference information comprises a service component identifier assigned for indicating conveyance of information related to the traffic information service, an identifier of the second information message, and a version number of the second information message.

16. The method of claim 14, wherein the steps of extracting are carried out when the second information message carries information notifying that the second information message is associated with multimedia object information provided for the multimedia information service.

17. The method of claim 16, wherein the information notifying that the second information message is associated with multimedia object information provided for the multimedia information service includes a service component identifier assigned for indicating conveyance of information related to a certain application service, an identifier of an information message, and a version number of the information message.

18. The method of claim 14, wherein the extracted reference information is information for further referring to more than one associated information message in addition to the second information message.

19. The method of claim 14, wherein the reference information is recorded in an area of management information of the extracted first information message.

20. The method of claim 14, wherein the reference information is recorded in one of components that follow management information of the first information message.

21. The method of claim 14, wherein the multimedia object information includes the data of video and/or audio attribute.

22. The method of claim 14, wherein the multimedia object information includes information for accessing the data of video and/or audio attribute transmitted through a signal channel or a transmission medium different from a signal channel or a transmission medium through which the first information message is transmitted.

23. The method of claim 22, wherein the information for accessing includes frequency information.

24. The method of claim 23, wherein the information for accessing further includes information about a manner in which the data of video and/or audio attribute is transferred.

25. The method of claim 22, wherein the information for accessing includes unique location information on a network about the data of video and/or audio attribute.

26. The method of claim 22, further comprising,

obtaining, by using the information for accessing, the data of video and/or audio attribute through the different signal channel or the different transmission medium.

27. The method of claim 14, further comprising,

decoding and outputting the data of video and/or audio and displaying, in connection with screen displayed by the outputting, at least part of content contained in the second information message.

28. The method of claim 27, wherein when the multimedia object information includes billing information, the decoding and outputting displays the billing information to a user and based on a response to the display, decodes and outputs the data of video and/or audio attribute.

29. The method of claim 14, wherein the multimedia object information includes at least one of play type, encoding format, size, collector information, and description information of the data of video and/or audio attribute.

30. An apparatus for receiving information, comprising:

a demodulator adapted for demodulating a received signal to output a frame sequence carrying application information;
