Abstract:
1. A method of processing broadcast data, the method comprising: performing RS (Reed-Solomon) encoding and CRC (Cyclic Redundancy Check) encoding on mobile service data to output an RS frame; dividing the RS frame into a plurality of portions; block processing data in one portion of the plurality of portions, wherein the block processing comprises: mapping the block processed data in the one portion into at least one region of a data group that comprises a plurality of regions, and adding a first known data sequence, a plurality of second known data sequences, and a transmission parameter to the data group; and transmitting a transmission frame including the data group, wherein the first known data sequence has a first pattern and the plurality of second known data sequences have a second pattern other than the first pattern, wherein the transmission parameter is positioned between the first known data sequence and one of the plurality of second known data sequences, and wherein the first known data sequence and the one of the plurality of second known data sequences differ from each other in length.
