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 in order to generate an RS frame belonging to an ensemble; mapping a portion of the RS frame into at least one of a plurality of regions of a data group, the data group including known data sequences, a fast information channel (FIC) segment and transmission parameter channel (TPC) data; and transmitting a transmission frame including data of the data group, wherein the FIC segment in the transmitted data group includes an FIC segment header and an FIC segment payload, wherein the FIC segment header comprises an error indicator for indicating whether at least one error is detected in the FIC segment and type information for indicating a type of data carried in the FIC segment, wherein the type information indicates that the FIC segment payload is carrying a portion of an FIC chunk when a value of the type information is set to ‘00’, wherein the type information indicates that the FIC segment is a null FIC segment not carrying a portion of the FIC chunk when the value of the type information is set to ‘11’, wherein the FIC chunk includes an FIC chunk header and an FIC chunk payload, wherein the FIC chunk payload includes an ensemble identifier for identifying the ensemble and protocol version information that indicates a version of a structure of the ensemble, wherein a size of the FIC chunk is determined by a number of ensembles and a number of mobile services provided in a physical transmission channel, and wherein the TPC data comprise FIC version information for indicating a change of contents in the FIC chunk.
