Abstract:
1. A method of transmitting a broadcast signal from a transmitter, the method comprising: pre-processing mobile data, wherein the pre-processing of the mobile data comprises: multiplexing the formed mobile data packets with main data packets including main data; performing systematic RS encoding on the main data and non-systematic RS encoding on the mobile data; interleaving the systematic RS encoded main data and the non-systematic RS encoded mobile data in the data groups; and transmitting a transmission frame including the data groups having the interleaved systematic RS encoded main data and the interleaved non-systematic RS encoded mobile data, wherein a parade of the data groups are transmitted during slots in the transmission frame, the slots being basic time periods for multiplexing the mobile data and the main data, wherein the TPC data includes information about a parade repetition cycle indicating a number of transmission frames that do not contain the parade and that are between transmission frames that do contain the parade, wherein the data groups include a plurality of regions to which the data blocks are mapped according to the SCCC block mode identifying a relationship between the plurality of regions and the data blocks.
