ABSTRACT:
A method includes performing Reed Solomon (RS) and Cyclic Redundancy Check encoding on mobile data and a table including access information of the data and information identifying a stream where data decryption keys are obtained, thereby forming an RS frame, which is divided into groups. Each group includes a portion of the RS frame data, known data sequences, fast information channel (FIC) data, and transmission parameter channel (TPC) data. The FIC data includes information for rapid mobile service acquisition. The TPC data includes information for indicating an FIC data update. A broadcast signal including the groups is transmitted. The RS frame size is L (rows)×N (column size of the RS frame) bytes. Each row has an M-byte header, leaving the remainder available for data. 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.
