Patent ID: 8310976

Claim:
A receiving system, comprising: a tuner for receiving a broadcast signal, including mobile service data, signaling data, and a plurality of known data sequences; a demodulator for demodulating the received broadcast signal; a block decoder for turbo-decoding the mobile service data in the demodulated broadcast signal in block units; and a Reed-Solomon (RS) frame decoder for forming an RS frame including the turbo-decoded mobile service data, detecting at least one error in the RS frame by performing first cyclic redundancy check (CRC)-decoding on the RS frame, correcting the detected at least one error in the RS frame by performing RS-decoding on the RS frame according to a result of the first CRC-decoding, performing second CRC-decoding on the RS-decoded RS frame if at least one column of the RS-decoded RS frame is not corrected, and de-randomizing a payload of the RS frame on which at least the RS-decoding or the second CRC-decoding is performed, wherein the de-randomized payload of the RS frame comprises mobile/handheld (M/H) data packets, wherein each of the M/H data packets includes a 2-byte M/H header, k number of stuffing bytes (wherein k≧0) and a (N−2−k)-byte M/H payload, and wherein each 2-byte M/H header includes an error indicator field indicating whether any error is detected in the corresponding M/H data packet.
