Abstract

A method for identifying traffic information includes receiving traffic data including a first identifier, information that is encoded, and information corresponding to a field indicative of an encoding scheme. The first identifier enables a determination of a type of information that is included within the received traffic data. The method also includes determining a type of information included within the received traffic data based on the first identifier and determining encoding information based on the field indicative of an encoding scheme included in the received traffic data only if the first identifier enables a determination that the received traffic data includes a field indicative of an encoding scheme. The method further includes identifying the information that is encoded based on the determined encoding information.

Claims

1. A method for processing traffic data at a terminal that includes a receiver and decoder, the method comprising:

receiving, at a receiver, traffic data including a Transport Protocol Experts Group Message (TPEG-Message) including a message management container, an event container, and a location container; and

decoding, at a decoder, the received traffic data,

wherein the event container includes a status component and an additional information component, and the additional information component includes text information and a language code,

wherein the TPEG-Message further includes first information identifying a specific encoding scheme of a character string of the text information for the additional information component,

wherein the status component includes a first identifier for identifying the status component, and

wherein the additional information component includes a second identifier for identifying the additional information component.

2. The method of claim 1, wherein the message management container includes information corresponding to a generation time of information reflected in the traffic data.

3. The method of claim 2, wherein the generation time relates to a plurality of message component structures that correspond to more than one of a predicted or current traffic tendency, a predicted or current amount of traffic, a predicted or current speed, a predicted or current time to traverse a particular link, or a link descriptor including a field indicative of an encoding mechanism used to encode the link descriptor.

4. The method of claim 3, wherein each message component structure corresponding to a link descriptor further comprises an identifier specific to a type of information and the first identifier is an identifier, in a message component structure, corresponding to a link descriptor.

5. The method of claim 3, wherein a plurality of message component structures corresponding to a link descriptor are included, and a single field indicative of an encoding mechanism is used to encode the link descriptors.

6. The method of claim 3, wherein a plurality of message component structures corresponding to link descriptors are included, wherein each link descriptor is associated with a field indicative of an encoding mechanism used to encode the link descriptor.

7. The method of claim 6, wherein the plurality of message component structures corresponding to link descriptors include a descriptor encoded in a plurality of languages or formats.

8. The method of claim 1, wherein the first information includes a value, associated within a reference table on the receiver, with the language or format of a descriptor.

9. The method of claim 1, wherein the TPEG-Message includes a text descriptor corresponding to a specific link, wherein the text descriptor is encoded using the encoding method indicated by the field.

15. The method of claim 1, wherein the first information corresponding to a field indicative of an encoding scheme of the character string includes information indicating a language in which the character string information is encoded.

16. The method of claim 1, wherein the first information corresponding to a field indicative of an encoding scheme of the character string includes information indicating an encoding type of the character string in a particular language.

17. The method of claim 16, wherein the encoding type indicates one of multiple, different types of encoding a character string in the particular language.

18. The method of claim 16, wherein the encoding type indicates that the character string is encoded in at least one of a complete encoding type for the particular language, a combination encoding type for the particular language, and a unicode encoding type for the particular language.

19. The method of claim 18, wherein the encoding type indicates that the character string is encoded in the complete encoding type for the particular language.

20. The method of claim 18, wherein the encoding type indicates that the character string is encoded in the combination encoding type for the particular language.

21. The method of claim 18, wherein the encoding type indicates that the character string is encoded in the unicode encoding type for the particular language.

10. An apparatus for processing traffic data, the apparatus comprising:

a receiver configured to receive traffic data including a Transport Protocol Experts Group Message (TPEG-Message) including a message management container, an event container, and a location container; and

a decoder configured to decode the received traffic data,

wherein the event container includes a status component and an additional information component, and the additional information component includes text information and a language code,

wherein the TPEG-Message further includes a first information identifying a specific encoding scheme of a character string of the text information for the additional information component,

wherein the status component includes a first identifier for identifying the status component, and

wherein the additional information component includes a second identifier for identifying the additional information component.

11. The apparatus of claim 10, wherein the message management container includes information corresponding to a version number of information reflected in the traffic data.

12. The apparatus of claim 10, wherein the message management container including information corresponding to a generation time of information reflected in the traffic data.

13. The apparatus of claim 10, wherein the TPEG-Message further includes information corresponding to a data length of the received data.

14. A method for processing traffic data at a terminal that includes a receiver and decoder, the method comprising:

receiving, at a receiver, traffic data including a Transport Protocol Experts Group Message (TPEG-Message) including a message management container, an event container, and a location container; and

decoding, at a decoder, the received traffic data,

wherein the event container includes a status component and an additional information component, and the additional information component includes text information and a language code,

wherein the TPEG-Message further includes a first information identifying a specific encoding scheme of a character string of the text information for the additional information component,

wherein the status component includes a first identifier for identifying the status component,

wherein the additional information component includes a second identifier for identifying the additional information component,

wherein the character string of the text information includes a first character string and a second character string, the first character string being equal to the second character string, and

wherein the first information includes a first field indicative of an encoding scheme of the first character string and a second field indicative of an encoding scheme of the second character string, the first information corresponding to the first field indicative of the encoding scheme of the first character string being different from the first information corresponding to the second field indicative of the encoding scheme of the second character string.
