Patent ID: 8300569

Claim:
A method of processing broadcast data in a broadcast transmitter, the method comprising: performing, by a Reed-Solomon (RS) encoder, RS encoding and Cyclic Redundancy Check (CRC) encoding on mobile service data and building at least primary RS frames belonging to a primary ensemble or secondary RS frames belonging to a secondary ensemble depending on RS frame mode information that indicates a single frame mode or a dual frame mode; mapping each of the built at least primary or secondary RS frames into groups, wherein each of the groups comprises known data sequences, a fast information channel (FIC) segment, and transmission parameter channel (TPC) data; and transmitting a transmission frame containing the groups, wherein at least one FIC segment transmitted through the transmission frame includes status information of a mobile service, wherein at least one FIC segment transmitted through the transmission frame includes an ensemble identifier to identify one of the primary ensemble and the secondary ensemble, wherein the status information of the mobile service is assigned with two bits, wherein a first bit indicates whether the mobile service is active or inactive, and a second bit indicates whether the mobile service is hidden or not, wherein the ensemble identifier comprises a parade identifier to identify a parade which carries at least the primary ensemble or the secondary ensemble, and wherein the TPC data include FIC version information, the RS frame mode information and the parade identifier.
