Patent ID: 8307400

Claim:
A method of processing data in a transmitter, the method comprising: separating ensembles including mobile service data; building a Reed-Solomon (RS) frame including the mobile service data, wherein building the RS frame comprises: performing RS encoding for each of a plurality of columns of a payload of the RS frame; and adding cyclic redundancy check (CRC) data to the RS encoded payload of the RS frame; dividing the built RS frame into RS frame portions; encoding signaling data including fast information channel (FIC) data including cross layer information for mobile service acquisition and transport parameter channel (TPC) data including FIC version information for identifying an update of the FIC data, wherein the TPC data is RS-encoded at a first code rate, and the FIC data is block-interleaved after being RS-encoded at a second code rate, and wherein the TPC data is not included in the FIC data; forming a data group including data of an RS frame portion and the signaling data; transmitting a broadcast signal including the formed data group, wherein the ensemble is carried through a parade, the parade being a collection of data groups and the TPC data further includes information for a parade repetition cycle which represents a number of frames which do not contain a current parade and which are between frames that contain the current parade, and wherein the TPC data is included in each of the data groups belonging to the parade and same information for the parade repetition cycle is transmitted repeatedly through the data groups of the parade.
