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.

Encoding and decoding traffic information using encoding fields

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.

Method and an apparatus for transmitting and receiving traffic information by using file transfer

The present invention provides a virtual channel table (VCT) data structure, transport stream discrimination method, and digital broadcast receiver, by which streams transferred within a channel can be identified with VCT only by extending a VCT syntax according to PSIP (program and system information protocol) of ATSC (advanced television systems committee) prescribed as a digital TV standard. The present invention adds the additional explanation (component name string) descriptor for the stream to the service location descriptor of the VCT, whereby various streams transferred over one channel can be uniquely identified. Therefore, the present invention enables a user of the digital broadcast receiver to select a stream more quickly.
