    • A receiving system and a method of processing broadcast signal are disclosed. The receiving system includes a signal receiving unit, an equalizer (2003), a block decoder (2005), and an RS frame decoder (2006). The signal receiving unit receives and demodulates a broadcast signal. The equalizer (2003) channel-equalizes a data group included in the demodulated broadcast signal. The block decoder (2005) performs turbo-decoding on mobile service data of the channel-equalized data group. And, the RS frame decoder (2006) determines a number of CRC errors of an RS frame including the turbo-decoded mobile service data, generates a reliability map including reliability information corresponding to each data byte of the RS frame. Herein, the reliability information is set-up as a soft value. Also, for each column, when the number of the determined CRC errors is greater than a number of RS parity bytes of the RS frame, the RS frame decoder (2006) sets a predetermined number of erasure points in the corresponding data bytes starting from the lowest reliability value for the corresponding column, and performs RS-erasure decoding on the column.

    • A receiving system and a method of processing data are disclosed herein. The receiving system includes a receiving unit, an equalizer, a block decoder, and an RS frame decoder. The receiving unit receives and demodulates a broadcast signal. Herein, the broadcast signal includes at least a mobile service data and a data group including a plurality of known data sequences. The equalizer channel-equalizes the data group included in the demodulated broadcast signal by using the plurality of the known data sequences. The block decoder performs turbo-decoding in block units on data of portion allocated to the channel equalized data group. And, the RS frame decoder configures an RS frame by gathering data of the turbo decoded M number of portions, wherein M is an integer greater than 1 (M>1). And, when a number of contiguous CRC errors is equal to (a maximum number of errors that can be corrected by RS erasure decoding)-!- 1, wherein the number of contiguous CRC errors is determined by performing CRC decoding on each row of the RS frame, the RS frame decoder sets up erasure points in all data of the rows including the CRC errors, so as to perform RS erasure decoding on all columns of the RS frame in the column direction.

    • A receiving system and a method of processing data are disclosed herein. The receiving system comprises a signal receiving unit, a known sequence detector, a first equalization unit, a second equalization unit, a block decoder, and an error correction unit. The signal receiving unit receives a broadcast signal including a data group multiplexed mobile service data with a plurality of known data sequences. The known sequence detector detects known data sequences from the broadcast signal. The first equalization unit updates an equalization coefficient by using the known data sequence during the known data section, thereby primarily channel-equalizing the known data sequence. The second equalization unit interpolates or extrapolates a converging equalization coefficient, thereby secondarily channel-equalizing the mobile service data, when the equalization coefficient converge. The block decoder performs turbo-decoding on the channel-equalized mobile service data in block units. And, the error correction unit performs error correction decoder on the decoded mobile service data, thereby correcting errors generated in the mobile service data.
