## Abstract

A method of processing broadcast data in a broadcast transmitting system includes Reed-Solomon (RS) encoding and Cyclic Redundancy Check encoding an RS frame payload including mobile service data to build an RS frame, wherein the RS frame payload comprises a plurality of mobile and handheld transport packets; first encoding data of the RS frame with a first encoding code; second encoding signaling data with a second encoding code, wherein the signaling data include fast information channel (FIC) data and transmission parameter channel (TPC) data, the FIC data including information for rapid mobile service acquisition and the TPC data including a parade identifier for identifying a parade to which a current data group belongs; mapping the first encoded data into data groups and adding known data sequences and the second encoded signaling data to each of the data groups; and transmitting a transmission frame including data of the data groups.
