Abstract:
1. A method of processing a broadcast signal in a transmitting system, the method comprising: performing Reed Solomon (RS) encoding and Cyclic Redundancy Check (CRC) encoding on mobile service data in order to generate an RS frame belonging to an ensemble comprising a service information table including access information of an IP stream for the mobile service data; encoding transmission parameter channel (TPC) data and fast information channel (FIC) data with a first encoding code and, wherein the FIC data include information for rapid mobile service acquisition, and wherein the TPC data include FIC version information for indicating an update of the FIC data and RS frame mode information for indicating at least a single frame mode or a dual frame mode; encoding data of the RS frame with a second encoding code; mapping the encoded data of the RS frame to data groups, each of the data groups including regions A, B, C and D and comprising the encoded TPC data and FIC data and a plurality of known data sequences, wherein the encoded data of the RS frame are mapped to the regions A, B, C and D of each of the data groups when the RS frame mode information indicates the single frame mode, and wherein the encoded data of the RS frame are mapped to either the regions A and B or the regions C and D of each of the data groups when the RS frame mode information indicates the dual frame mode; and transmitting the broadcast signal comprising data of the data groups, wherein the RS frame comprises an RS frame payload including the mobile service data, RS parity data added at bottom ends of columns of the RS frame payload and CRC checksum data added at right ends of rows of the RS frame payload including the RS parity data, and wherein the TPC data further include a first-assigned data group number for a parade and a parade identifier for identifying the parade, the parade being a collection of the data groups.
