Patent ID: 8547987

Claim:
An apparatus for transmitting a broadcast signal, the apparatus comprising; a first encoder configured to encode mobile data for FEC (forward error correction) in order to build RS (Reed-Solomon) frames that are divided into a plurality of portions; a block encoder configured to convert one of the plurality of portions of the RS frames to SCCC (Serial Concatenated Convolutional Coding) blocks according to SCCC block mode information and to encode the SCCC blocks according to SCCC code mode information; a second encoder configured to encode signaling information that includes the SCCC block mode information and the SCCC code mode information, wherein the SCCC block mode information indicates a relationship between the one of the plurality of portions of the RS frames and the SCCC blocks and the SCCC code mode information indicates a specific code rate; a group formatter configured to map the SCCC blocks to data blocks to form a data group that includes a plurality of regions, wherein the plurality of regions includes a plurality of the data blocks with the encoded signaling information inserted into a specific data block of the plurality of data blocks; a packet formatter configured to form data packets including data in the data group; and a transmitter configured to transmit the broadcast signal including the data packets, wherein the data group includes audio signals having parameters that are generated based on the audio signals.
