DIGITAL BROADCASTING SYSTEM AND DATA PROCESSING METHOD
First Claim
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.

Abstract
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.

8. A digital broadcast system comprising:
-
a receiver 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; a known sequence detector detecting known data included in the received broadcast signal; a channel equalizer using the detected known data, thereby channel-equalizing the received mobile broadcast service data corresponding to the detected known data; a demultiplexing unit extracting a video data from the mobile broadcast service data; a NAL parsing unit parsing the extracted video data by a NAL unit; and a video data decoding unit decoding the parsed video data based on header information of the parsed NAL unit. - View Dependent Claims (9, 10, 11, 12, 13, 14)
