Patent ID: 8165803

Claim:
A broadcast receiver comprising: a receiving unit for receiving a broadcast signal comprising a data group, the data group comprising mobile broadcast service data, known data sequences, signaling information and main broadcast service data, the mobile broadcast service data including prediction information, wherein the data group is divided into data blocks, wherein a first known data sequence of the known data sequences, a third known data sequence of the known data sequences, a fourth known data sequence of the known data sequences, a fifth known data sequence of the known data sequences and a sixth known data sequence of the known data sequences are spaced 16 segments apart, wherein a second known data sequence of the known data sequences includes a first M-symbol sequence and a second M-symbol sequence that have a same pattern, and wherein the second known data sequence and the signaling information are included in a fourth data block of the data blocks; a Reed-Solomon (RS) frame decoder for performing cyclic redundancy check-decoding (CRC-decoding) and RS-decoding on an RS frame, the RS frame comprising at least one data packet including the mobile broadcast service data, RS parity data generated based on the at least one data packet, and CRC checksum data generated based on the at least one data packet and the RS parity data in order to correct errors in the mobile broadcast service data; and a storage unit for storing the prediction information included in the error-corrected mobile broadcast service data.
