Patent ID: 8135034

Claim:
A method of processing data in a receiver, the method comprising: receiving a broadcast signal comprising data groups, wherein each of the data groups is divided into data blocks that comprise mobile service data, fast information channel (FIC) data, transmission parameter channel (TPC) data, and a plurality of known data sequences, wherein one of the plurality of known data sequences includes a first M-symbol sequence and a second M-symbol sequence that have a same pattern, and wherein M is an integer greater than 1 ; estimating an initial frequency offset by partial correlating the first M- symbol sequence and the second M-symbol sequence; performing carrier recovery on the broadcast signal based on the estimated initial frequency offset; decoding the FIC data and the TPC data, which are independent from each other, from the carrier recovered broadcast signal, the FIC data comprising cross layer information for mobile service acquisition, and the TPC data comprising FIC version information for identifying an update of the FIC data and Serial Concatenated Convolutional Code (SCCC) block mode information for identifying a relationship between SCCC blocks and the data blocks, wherein each SCCC block is constituted of a single data block when a value of the SCCC block mode information is set to ‘ 00 ’ and each SCCC block is constituted of two data blocks when the value of the SCCC block mode information is set to ‘01’; turbo-decoding the mobile service data in the carrier recovered broadcast signal in SCCC block units according to the SCCC block mode information included in the TPC data; building a Reed-Solomon (RS) frame including the turbo-decoded mobile service data and acquiring a service map table (SMT) from an ensemble including the RS frame, the ensemble being identified by an ensemble identifier, and the SMT comprising a header including the ensemble identifier and a payload including service acquisition information; and accessing IP datagrams of the mobile service data from the RS frame according to the service acquisition information.
