Patent ID: 8325766

Claim:
A method of transmitting a broadcast signal, the method comprising: encoding mobile data for forward error correction (FEC) to build Reed-Solomon (RS) frames according to mode information; dividing at least one of the RS frames into portions; Serial Concatenated Convolutional Code (SCCC) encoding mobile data in one portion of the at least one of the RS frames; encoding signaling data for the mobile data; forming at least one data group including the SCCC encoded mobile data, the encoded signaling data, and known data sequences, wherein the at least one data group includes data blocks with the encoded signaling data inserted into a specific one of the data blocks; and transmitting a transmission frame including a parade of data groups, wherein the parade includes a collection of data groups and carries data of one or two of the RS frames according to the mode information, wherein encoding the signaling data comprises: RS encoding first signaling data of the signaling data, wherein the first signaling data includes the mode information and a number of data groups per a subframe within the transmission frame; RS encoding second signaling data of the signaling data, wherein the second signaling data provides cross-layer information between a physical layer and an upper layer for rapid service acquisition; interleaving the RS encoded second signaling data; combining the first signaling data and the interleaved second signaling data; and performing Parallel Concatenated Convolutional Code (PCCC) encoding on the combined signaling data.
