1. A method of processing data, comprising:

  • receiving a broadcast signal including mobile broadcast service data and main broadcast service data,wherein the mobile broadcast service data configures a data group, wherein the data group is divided into a plurality of regions, wherein known data sequences are linearly inserted in some regions among the plurality of regions, and wherein initialization data are inserted at a beginning portion of each known data sequence, the initialization data being used for initializing a memory included in a trellis encoder of a digital broadcast transmitting system;

    detecting known data included in the received broadcast signal;

    channel-equalizing the received mobile broadcast service data corresponding to the detected known data, using the detected known data;

    extracting a video data from the mobile broadcast service data;

    parsing the extracted video data by a NAL unit; and

    decoding the parsed video data based on header information of the parsed NAL unit.
