Abstract:
1. A receiving system, comprising: a receiving unit receiving and demodulating a broadcast signal, wherein the broadcast signal includes at least mobile service data and a data group including a plurality of known data sequences; an equalizer channel-equalizing the data group included in the demodulated broadcast signal by using the plurality of known data sequences; a block decoder performing turbo-decoding in block units on data of a portion allocated to the channel equalized data group; and an RS frame decoder configuring 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, the number of contiguous CRC errors being determined by performing CRC decoding on each row of the RS frame, setting up erasure points in all data of the rows including the CRC errors, thereby performing RS erasure decoding on all columns of the RS frame in the column direction.
