Patent ID: 8001572

Claim:
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 signaling information table including access information of the mobile service data, fast information channel (FIC) data, and transmission parameter channel (TPC) data, wherein the mobile service data and the signaling information table are encapsulated into at least one Reed-Solomon (RS) frame, 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; demodulating the received broadcast signal; extracting the signaling information table from the demodulated broadcast signal; identifying a stream where keys to decrypt the mobile service data are obtained using the extracted signaling information table; and decrypting the mobile service data using the keys, wherein a size of the at least one RS frame is L (rows)×N+2 (column size of the RS frame) bytes, each of the rows 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 or without wrapping around at the end of each row to the next row, and wherein L, M, and N are integers.
