    摘要: 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.

    摘要: A digital television transmitting system includes a pre-processor, a packet generator, an RS encoder, and a trellis encoder. The pre-processor pre-processes enhanced data by coding the enhanced data for first forward error correction (FEC) and expanding the FEC-coded enhanced data. The packet generator generates first and second enhanced data packets including the pre-processed enhanced data and main data packets and multiplexes the enhanced and main data packets. The first enhanced data packet includes an adaptation field including the pre-processed enhanced data and second enhanced data packet includes a payload region including the pre-processed enhanced data. The RS encoder performs RS encoding on the multiplexed data packets for second forward error correction (FEC), and the trellis encoder performs trellis encoding on the RS-coded data packets.
