Abstract:
1. A method of transmitting broadcast data in a digital broadcast transmitting system, the method comprising: Reed Solomon-Cyclic Redundancy Check (RS-CRC) encoding, by a Reed-Solomon (RS) frame encoder, mobile data to build at least one of a primary RS frame belonging to a primary ensemble and a secondary RS frame belonging to a secondary ensemble; mapping the RS-CRC encoded mobile data into data groups and adding known data sequences, a portion of fast information channel (FIC) data, and transmission parameter channel (TPC) data to each of the data groups, wherein the FIC data includes information for rapid mobile service acquisition, and wherein the TPC data includes version information for indicating an update of the FIC data and a parade identifier to identify a parade which carries at least one of the primary ensemble and the secondary ensemble; multiplexing data in the data groups and main data; and transmitting a transmission frame including the multiplexed data, wherein the FIC data are divided into a plurality of FIC segment payloads, and each FIC segment including an FIC segment header and one of the plurality of FIC segment payloads is transmitted in each of the data groups, wherein the primary ensemble includes at least one mobile service and a first service map table and the secondary ensemble includes at least one mobile service and a second service map table, wherein the first service map table comprises a first ensemble identifier to identify the primary ensemble and the second service map table comprises a second ensemble identifier to identify the secondary ensemble, and wherein the first and second ensemble identifiers include the parade identifier, respectively.
