TRANSMITTING/RECEIVING SYSTEM AND METHOD OF PROCESSING BROADCAST SIGNAL IN TRANSMITTING/RECEIVING SYSTEM

摘要

A receiving system and a method of processing broadcast signal. The receiving system includes a signal receiving unit, an equalizer, a turbo decoder (2171 ), a demultiplexer (2113), first (2114) and second (2116) error correctors, and a block interleaver (2115). The signal receiving unit receives a broadcast signal, the broadcast signal comprising a data group, which includes mobile service data, a plurality of known data sequences, and signaling data, and demodulating the received broadcast signal. The equalizer channel-equalizes the data group using at least one of the plurality of known data sequences. The turbo decoder (2111 ) turbo-decodes the signaling data contained in the channel-equalized data group. The demultiplexer (2112) distinguishes transmission parameter channel (TPC) data and fast information channel (FIC) data from the turbo-decoded signaling data. The first error corrector (2114) corrects an error in the TPC data. The block deinterleaver (21 15) block-deinterleaves the FIC data. The second error corrector (2116) corrects an error in the block-deinterleaved FIC data.
