    摘要: The present invention provides a method of processing data in digital broadcasting system. The method includes 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.

    摘要: A method of processing a digital broadcast signal in a transmitter includes encoding signaling information including a transmission parameter channel, including transmission parameters and a fast information channel (FIC) including cross layer information for mobile service acquisition, and transmitting the broadcast signal including ensembles including the encoded signaling information. The FIC is divided into FIC segments, each FIC segment including a FIC segment header and a FIC segment payload. The FIC segment header includes type information indicating a type of the FIC segment, the FIC further including a first ensemble identifier identifying a specific ensemble including a service map table (SMT). The SMT includes a header including a second ensemble identifier corresponding to the first ensemble identifier, a payload including service acquisition information of the specific ensemble, and IP access information of a mobile service for acquiring an IP datagram of the mobile service from the specific ensemble.
