1. A digital broadcast transmitter, comprising:

  • a pre-processor pre-processing traffic information data including a traffic information message by encoding the traffic information data and by generating a traffic information data packet including the encoded traffic information data and known data;

    a multiplexer multiplexing the traffic information data packet with one or more main audio and video (AV) data packets;

    a trellis encoder having at least one memory and trellis-encoding the multiplexed data packets, the at least one memory being initialized by initialization data when data outputted from the multiplexer correspond to a beginning of a known data sequence; and

    a data transmission unit inserting synchronization data into the trellis-encoded data, modulating the trellis-encoded data having the synchronization data, and transmitting the modulated data, wherein the traffic information message includes at least one of road change information and traffic route shape information.
