METHOD FOR TRANSMITTING AND RECEIVING TRAFFIC INFORMATION AND APPARATUS THEREOF

摘要

A method for transmitting and receiving traffic information and apparatus therefore are disclosed, by which the traffic information can be efficiently delivered to a broadcast receiving terminal. The present invention includes multiplexing audio data, video data, component data carrying the traffic information, time information for the traffic information, and stream parsing information including descriptor table information for parsing the traffic information into broadcast transport streams, performing error correction encoding on the multiplexed streams and interleaving the encoded signals, mapping a scattered pilot signal changed according to a time and a continual pilot signal fixed according to the time within one frame of the interleaved signals, modulating the mapped signals within the frame by OFDM and inserting portions of the modulated signals within the frame in a guard interval of the modulated frame, and converting the signal having the guard interval inserted therein to an RF signal and transmitting the RF signal.
