Abstract:
1. A method of processing broadcast data in a broadcast transmitter, the method comprising: performing, by a Reed Solomon (RS) frame encoder, RS encoding and Cyclic Redundancy Check (CRC) encoding on mobile service data, thereby generating an RS frame; mapping a portion of the RS frame into at least one region of a group that includes a plurality of regions, wherein the group further includes a plurality of 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 identifying an update of the FIC data; and transmitting a transmission frame including the group, wherein a time interval of the transmission frame is divided into a plurality of sub-frames, wherein the TPC data further includes information that indicates a current sub-frame number within the transmission frame, wherein the RS frame belongs to an ensemble, wherein the ensemble comprises a service map table (SMT) including access information of the mobile service data, and wherein an Internet Protocol (IP) datagram carrying the SMT includes a well-known IP address and a well-known User Datagram Protocol (UDP) port number.
