    • 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.
    • 因此,公开了一种用于发送和接收交通信息和装置的方法,通过该方法可以将交通信息有效地传送到广播接收终端。 本发明包括复用音频数据,视频数据,承载业务信息的分量数据,用于业务信息的时间信息,以及包括用于将业务信息解析成广播传输流的描述符表信息的流解析信息,对多路复用 对编码信号进行流和交织,映射根据时间改变的分散导频信号和根据交织信号的一帧内的时间固定的连续导频信号,通过OFDM调制帧内的映射信号,并插入调制的部分 在调制帧的保护间隔内的帧内的信号,以及将其中插入有保护间隔的信号转换为RF信号并发送RF信号。
