1. digital data transmission equipment comprises:

  • Have output port, be used for the input port (315) of input information bits stream and be used to import the multiplexer (305) of the input port (320) of placeholder bit stream, be used for multiplexed bit stream, with the multiplexed bit stream (410) that is formed on output port, exporting from the input port input;

    Data formatter (105-120), the bit that is used for receiving multiplexed bit stream and uses the described message bit stream in the multiplexed bit stream of described reception to derive substitutes the bit of the described placeholder bit stream in the multiplexed bit stream that receives, to form the bit stream of revising (117);

    Be used to encode the bit stream revised to produce an encoder (125,138,140,330) of bitstream encoded (460);

    AndBe used to send the transmitter (152) of bitstream encoded (470).
