Patent ID: 8279990

Claim:
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 the data group, wherein an FIC chunk includes an FIC chunk header and an FIC chunk payload, wherein the FIC chunk payload includes at least one ensemble loop and at least one service loop, wherein the FIC chunk header includes first length information, second length information and third length information, wherein the first length information indicates a length of at least one extension field added to the FIC chunk header, wherein the second length information indicates a length of at least one extension field added to the at least one ensemble loop, wherein the third length information indicates a length of at least one extension field added to the at least one service loop, wherein the FIC chunk is segmented into a plurality of FIC segment payloads and the FIC segment in the transmitted data group includes an FIC segment header and one of the plurality of FIC segment payloads, wherein the FIC segment header includes type information indicating a type of data carried in the FIC segment, wherein the TPC data includes FIC version information for indicating an update of the FIC chunk, and wherein the at least one extension field is added to the at least one service loop by one or more minor version level changes of a syntax of the FIC chunk.
