Abstract
A method of processing digital broadcast data in a digital broadcast transmitter includes performing Reed-Solomon (RS) encoding and Cyclic Redundancy Check encoding on mobile service data to build an RS frame; dividing the RS frame into a plurality of portions; mapping one of the plurality of portions into a first data group and inserting known data sequences, transmission parameters, place holders for non-systematic RS parity data, place holders for main service data, and place holders for MPEG header data into the first data group; deinterleaving data of the first data group to output a second data group; and removing the place holders for non-systematic RS parity data and the place holders for main service data in the second data group and replacing the place holders for MPEG header data in the second data group with MPEG header data to output mobile service data packets.
