Patent ID: 8190979

Claim:
A method of transmitting a broadcast signal in a transmitter, the method comprising: pre-processing mobile data, wherein pre-processing the mobile data comprises: encoding the mobile data to build a 2-dimensional Reed-Solomon (RS) frame through which the mobile data belonging to an ensemble including a service of the mobile data is RS-cyclic redundancy check (RS-CRC) encoded, separating the encoded RS frame into a plurality of portions; dividing the plurality of portions into serial concatenated convolutional coding (SCCC) blocks according to an SCCC block mode; SCCC-outer-encoding the data in the SCCC blocks according to an SCCC code mode; outputting data blocks including the SCCC-outer-encoded data; forming data groups of the mobile data, wherein each of the data groups includes signaling information, known data sequences and one of the plurality of portions, wherein the signaling information includes fast information channel (FIC) data having cross layer information between a physical layer and an upper layer and further includes transmission parameter channel (TPC) data indicating a version of the FIC data; and forming mobile data packets including data in the data groups; multiplexing the mobile data packets and main data packets including main data; performing systematic RS encoding on main data in the multiplexed data packets; performing non-systematic RS encoding on mobile data in the multiplexed data packets; and transmitting a transmission frame including the RS-encoded main data and the RS-encoded mobile data, wherein a parade of the formed data groups is transmitted during slots in the transmission frame, the slots being basic time periods for multiplexing the mobile data and the main data, wherein the transmission frame includes a plurality of sub-frames, and wherein the TPC data includes information indicating a current slot number within one of the sub-frames.
