1. method that is used to send transport information, this method comprises:

  • Transport information, audio signal, vision signal and the stream resolving information of Link Travel Time are multiplexed into broadcasting transmission signal;

    Described multiplexed signal is encoded in case wrong and coded signal interweaved;

    With the distribution pilot signal of time to time change and in time and fixing continuous pilot signal is mapped in respectively in the frame of the signal that is interweaved;

    Modulate the signal that shone upon and insert protection at interval in the frame of the signal of being modulated by Orthodoxy Frequency Division Multiplex (OFDM) scheme, this protection is the part of the signal modulated at interval;

    AndBecome the RF signal with inserting described protection described conversion of signals at interval, and launch the signal of being changed.
