    摘要: A digital broadcast system and a method of processing data are disclosed. The receiving system of the digital broadcast system includes a signal receiving unit, a first data processor, a second data processor, and an A/V decoder. The signal receiving unit receives at least one of first mobile service data that is transmitted according to a first transmission method and second mobile service data that is transmitted according to a second transmission method. The first data processor performs demodulation on the first mobile service data received by the signal receiving unit using a first demodulation method and corrects errors occurring in the demodulated first mobile service data. The second data processor performs demodulation on the second mobile service data received by the signal receiving unit using a second demodulation method and corrects errors occurring in the demodulated second mobile service data. The A/V decoder performs A/V decoding on mobile service data outputted from at least one of the first and second data processors.

    摘要: A DTV transmitter includes a pre-processor pre-processing enhanced data, a data formatter generating enhanced data packets including the pre-processed enhanced data, and a multiplexer multiplexing the enhanced data packets with main data packets. The transmitter further includes an RS encoder RS-coding the multiplexed packets by adding systematic RS parity data to each main data packet and by adding non-systematic RS parity place holders to each enhanced data packet, and a data interleaver interleaving the RS-coded packets. The non-systematic RS parity place holders are placed after the enhanced data within each interleaved enhanced data packet, and a sequence of known data place holders is periodically included in the interleaved enhanced data packets.
