Abstract
An apparatus and method for processing digital broadcast signal are provided. The method for processing a broadcast signal includes forming a data group having mobile broadcast service data, where forming the data group includes mapping the mobile broadcast service data into corresponding locations of the data group, adding known data sequences and signaling data into the data group, inserting place holder bytes for MPEG header and non-systematic Reed-Solomon (RS) parity, and de-interleaving data of the data group having the mobile broadcast service data, known data sequences, signaling data and place holder bytes, and formatting mobile broadcast service data packets including the de-interleaved data of the data group, where formatting the mobile broadcast service data packets includes removing place holder bytes for the non-systematic RS parity, and replacing place holder bytes for the MPEG header with the MPEG header.
