A transmitting/receiving system and a data processing method are provided to receive both MPEG data and supplementary data by having configuration elements capable of processing the MPEG data and supplementary data together and to minimize the error when determining a signal. A broadcasting receiver comprises an MPEG(Moving Picture Expert Group) data processor(100) and a supplementary data processor(200). The MPEG data processor comprises a demodulator(47), a comb filter(48), a channel equalizer(49), a slicer estimator(50), a phase restorer(51), a trellis decoder(52), a first data deinterleaver(53), a first reed Solomon decoder(54) and a data derandomiser(55). The supplementary data processor comprises an MPEG header removing unit(57), a null sequence removing unit(58), a second data deinterleaver(59) and a second reed Solomon decoder(60). A tuner receives first and second data transmitted from a transmitter. The demodulator demodulates the first data received in the tuner. A first interleaver performs first interleaving of the first data where the first error correction encoding is performed. A second encoder performs second error correction encoding for the second data and the first data where the first interleaving is performed. A second interleaver performs second interleaving of the first and second data where the second error correction encoding is performed. A trellis encoder performs trellis encoding of the first and second data where the second interleaving is performed.
