Digital broadcasting system and data processing method in digital broadcasting system

摘要

A method of transmitting a broadcast signal includes performing Reed-Solomon (RS) frame encoding and Cyclic Redundancy Check (CRC) encoding on first mobile service data to form a primary RS frame and on second mobile service data to form a secondary RS frame; encoding on at least the first mobile service data or the second mobile service data, in serial concatenated convolution code (SCCC) block units; encoding signaling information including transmission parameters, the transmission parameters including SCCC encoding information and RS frame encoding information; formatting a data group including the encoded first mobile service data and second mobile service data, wherein the first mobile service data are included in a first region within the data group and the second mobile service data are included in a second region within the data group, the second region being different from the first region; and transmitting the broadcast signal including the formatted data group.

1. A method of transmitting a broadcast signal in a transmitter, the method comprising:
forming Reed-Solomon (RS) frames, wherein the RS frames include a primary RS frame or primary and secondary RS frames per a parade depending on RS frame mode information that indicates a single frame mode or a dual frame mode, the primary RS frame including first mobile service data, the secondary RS frame including second mobile service data; encoding data in the RS frames in serial concatenated convolution code (SCCC) block units; encoding signaling information including transmission parameter channel (TPC) data and fast information channel (FIC) data, wherein the TPC data include FIC version information for indicating an update of the FIC data and the RS frame mode information; forming a data group including a first region and a second region that is different from the first region, wherein when the RS frame mode information indicates the dual frame mode, the first region of the data group includes the first mobile service data of the encoded data and the second region of the data group includes the second mobile service data of the encoded data; and transmitting the broadcast signal including the formed data group, wherein the primary RS frame comprises a payload of (N1 column*K row)-byte including the first mobile service data, RS parity data generated to each column direction based on the payload and a CRC checksum data generated to each row direction based on the payload and the RS parity data, wherein a size of the RS parity data is P1-byte, wherein the secondary RS frame comprises a payload of (N2 column*K row)-byte including the second mobile service data, RS parity data generated to each column direction based on the payload and CRC checksum data generated to each row direction based on the payload and the RS parity data, wherein a size of the RS parity data is P2-byte, wherein the data group further includes a plurality of known data sequences, and wherein the TPC data and the FIC data are inserted between a first known data sequence and a second known data sequence of the plurality of known data sequences.
