Abstract
A method and apparatus for receiving or providing traffic information are disclosed. The method for receiving the traffic information according to an embodiment includes receiving the traffic information, determining whether version information of the received traffic information is identical to version information of previously stored traffic information, and decoding the received traffic information if the version information of the received traffic information is not identical to the version information of the previously stored traffic information.
Claims26
A method for receiving traffic information, the method comprising:
- receiving the traffic information;
- determining whether version information of the received traffic information is identical to version information of previously stored traffic information;
- and
- decoding the received traffic information if the version information of the received traffic information is not identical to the version information of the previously stored traffic information.
A terminal for receiving traffic information, the terminal comprising:
- a broadcast module configured to receive the traffic information;
- a storage unit configured to store the received traffic information;
- a decoder configured to decode the traffic information;
- and
- a control unit configured to receive the traffic information via the broadcast module, determine whether version information of the received traffic information is identical to version information of previously stored traffic information, and decode the received traffic information if the version information of the received traffic information is not identical to the version information of the previously stored traffic information.
A method for providing traffic information, the method comprising:
- generating at least one traffic information message;
- generating at least one service component including the at least one traffic information message;
- and
- generating traffic information including a transport frame including the at least one service component,
- wherein the traffic information includes version information.
A data structure embodied on a computer-readable medium, comprising:
- a field indicating a sync word;
- a field indicating version information;
- a field indicating a field length;
- and
- a service frame including at least one service component including at least one transport protocol expert group (TPEG) message.
A data structure embodied on a computer-readable medium, comprising:
- a field indicating an identifier for identifying a service component;
- a field indicating version information;
- a field indicating a field length;
- and
- at least one service component including at least one transport protocol expert group (TPEG) message.
