Abstract
A method of processing a digital broadcast signal includes Reed-Solomon (RS) encoding enhanced service data for each column of at least one RS frame payload and adding a Cyclic Redundancy Check (CRC) checksum byte at a right end of each row of the at least one RS frame payload to build at least one RS frame and forming data groups including the enhanced service data in the built RS frame and a plurality of known data sequences. Forming the data groups includes mapping the RS encoded enhanced service data into each of the data groups and inserting a place holder for a non-systematic RS parity into each of the data groups. The method further includes deinterleaving data in each of the data groups including the enhanced service data and the place holder and multiplexing the enhanced service data in each of the formed data groups with main service data.
