    摘要： A receiving system includes a tuner receiving a broadcast signal including data groups, each data group including enhanced data and known data sequences; a demodulator demodulating the received broadcast signal; a channel equalizer compensating channel distortions of the demodulated broadcast signal based on channel impulse responses (CIRs) estimated using at least two of the known data sequences; a block decoder decoding the enhanced data in the channel distortion compensated broadcast signal; a Reed-Solomon (RS) frame decoder correcting errors in the enhanced data based on a number of errors estimated by performing Cyclic Redundancy Check (CRC) decoding on an RS frame and a reliability map representing reliability information of the enhanced data; and a derandomizer derandomizing the error-corrected enhanced data.

    摘要： A digital broadcasting system and method of processing data are disclosed. Herein, a method of processing data in a transmitting system includes creating a data group including a plurality of mobile service data packets, re-adjusting a relative position of at least one main service data packet of a main service data section, the main service data section including a plurality of main service data packets, and multiplexing the mobile service data of the data group and the main service data of the main service data section in burst units. Herein, a position of an audio data packet among the main service data packets of the main service data section may be re-adjusted. Also, a position of an audio data packet included in the main service data section may be re-adjusted based upon a multiplexing position of the main service data section.

    摘要： A digital broadcast system including a broadcast receiving system and data processing method are disclosed. In the broadcast receiving system receiving broadcast signals, the broadcast receiving system includes a transmission parameter decoding unit, a known sequence detector, and a burst controller. The transmission parameter decoding unit detects information on a burst of a received signal from broadcast data having main service data and mobile service data multiplexed therein within a field of the received signal and outputs the detected information on the burst. The known sequence detector receives burst information from the transmission parameter decoding unit and uses the received burst information and known data position information included in the received data, so as to output burst control information. The burst controller uses the burst control information to control power supply of the broadcast receiving system.
