Abstract:
1. A receiving system, comprising: a signal receiving unit receiving a broadcast signal, the broadcast signal comprising a Reed-Solomon (RS) frame, which comprises K number of packets including A number of bytes of a first data processed with a first error encoding, an RS parity data generated based on the K number of packets, and a Cyclic Redundancy Check (CRC) checksum data generated based on the K number of packets and the RS parity data, and a second data processed with a second error encoding, wherein K>1 and A>1; a demodulating unit demodulating the received broadcast signal; a block decoder decoding by a block unit on the first data of the demodulated broadcast signal; an RS frame decoder correcting errors generated from the first data by an RS frame unit based on a number of errors estimated by performing CRC decoding on the RS frame and a reliability map representing reliability information of the first data; and a derandomizer derandomizing the error-corrected first data.
