Patent ID: 8472476

Claim:
A method of transmitting a broadcast signal in a transmitter, the method comprising: multiplexing mobile data and main data; and transmitting a transmission frame including a parade of data groups having the mobile data, known data sequences and signaling information, wherein at least one of the parade of data groups includes a plurality of regions having 10 data blocks, wherein a third data block of the 10 data blocks includes a first known data sequence of the known data sequences, wherein a fourth data block of the 10 data blocks includes a second known data sequence and a third known data sequence of the known data sequences, wherein a fifth data block of the 10 data blocks includes a fourth known data sequence of the known data sequences, wherein a sixth data block of the 10 data blocks includes a fifth known data sequence of the known data sequences, wherein a seventh data block of the 10 data blocks includes a sixth known data sequence of the known data sequences, wherein the signaling information includes fast information channel (FIC) data and transmission parameter channel (TPC) data, wherein the FIC data includes binding information between a service of the mobile data and an ensemble, wherein the TPC data includes an parade identifier for indicating the parade and Reed-Solomon (RS) frame mode information, wherein the signaling information is inserted into the fourth data block of the 10 data blocks, and wherein the mobile data belonging to the ensemble is Reed Solomon-cyclic redundancy check (RS-CRC) encoded through a 2-dimensional RS frame according to the RS frame mode information.
