Patent ID: 8225167

Claim:
A receiving system comprising: a receiving unit receiving a broadcast signal including a first group comprising mobile service data, known data and signaling data, the first group generated by interleaving a second group in a transmitting system, wherein the second group comprises data packets including a portion of the mobile service data, and wherein the data packets are spaced at least one data packet apart; a signaling decoder decoding the signaling data from the received broadcast signal; a demodulator demodulating the received broadcast signal based upon the known data; an equalizer channel-equalizing the demodulated broadcast signal based upon the known data; a turbo decoder performing turbo decoding on the mobile service data of the channel-equalized broadcast signal by applying a Serial Concatenated Convolutional Coding (SCCC) mode based upon the signaling data; and an error correction unit performing error correction decoding on the turbo-decoded mobile service data based upon the signaling data.
