Patent ID: 7986715

Claim:
A method of processing data in a receiver, the method comprising: receiving a broadcasting signal including a transmission frame at a tuner, wherein a parade of data groups in the broadcast signal is received during slots within the transmission frame, the slots being basic time periods for multiplexing mobile data and main data, and wherein each data group includes the mobile data, signaling information and known data sequences; demodulating, at a demodulator, the received broadcasting signal and obtaining, from the signaling information, fast information channel (FIC) data having cross layer information between a physical layer and an upper layer and transmission parameter channel (TPC) data indicating a version of the FIC data, wherein the TPC data are multiplexed with the FIC data, wherein the TPC data are Reed-Solomon (RS)-encoded data, and the FIC data are block-interleaved data after being RS-encoded; building, at a decoder, a Reed-Solomon (RS) frame corresponding to an ensemble of a service of the mobile data by collecting a plurality of data portions which are mapped to the data groups, the RS frame being a 2-dimensional data frame through which the mobile data belonging to the ensemble is Reed Solomon-cyclic redundancy check (RS-CRC) encoded; and performing error detection on the RS frame and error correction decoding on data in the RS frame at the decoder, wherein a payload of the RS frame includes 187 transport packets of the mobile data, each of the transport packets including a 2-byte header, wherein the header includes an error indicator indicating whether an error is detected in a transport packet and the transport packet includes an Internet protocol (IP) datagram.
