Abstract:
1. A method of processing broadcast data in a broadcast receiver, the method comprising: receiving a broadcast signal, the broadcast signal comprising mobile service data, a service map table (SMT) including access information of the mobile service data, known data sequences, fast information channel (FIC) data, and transmission parameter channel (TPC) data, wherein the FIC data includes information for rapid mobile service acquisition, and wherein the TPC data includes FIC version information for indicating an update of the FIC data; building Reed-Solomon (RS) frames including the mobile service data from the received broadcast signal, the RS frames belonging to an ensemble, the ensemble including the SMT; obtaining the SMT from the ensemble; and processing the mobile service data based on the access information of the SMT, wherein a size of at least one of the RS frames is L (rows)×N (column size of a payload of the RS frame) bytes, each row having an M-byte header leaving the rest of the row available for data, wherein the data in the rows are packed into the rows end-to-end, with possible wrapping around at the end of each row to the next row, wherein L, M, and N are integers, and wherein the FIC data and the SMT further include an ensemble identifier for identifying the ensemble, respectively.
