Abstract:
1. A method of transmitting a broadcast signal in a transmitter, the method comprising: encoding a 2-dimensional Reed-Solomon (RS) frame through which an ensemble including a service of mobile data is RS cyclic redundancy check (RS-CRC) encoded according to an RS frame mode, wherein the encoded RS frame is separated into a plurality of frame portions; dividing one of the plurality of frame portions into serial concatenated convolutional coding (SCCC) blocks according to an SCCC block mode; performing outer encoding of SCCC data in the SCCC blocks according to an SCCC code mode; outputting data blocks including the outer-encoded data; forming a data group including signaling information, known data sequences and the data blocks, wherein the signaling information includes first channel data having cross layer information between a physical layer and an upper layer and second channel data indicating a version of the first channel data, the first channel data block-interleaved by writing the first channel data row-by-row from left-to-right and top-to-bottom and reading the first channel data column-by-column from top-to-bottom and left-to-right; interleaving data in the data group, wherein the interleaved data group includes a plurality of regions to which the data blocks are mapped according to the SCCC block mode, the SCCC block mode identifying a relationship between the plurality of regions and the data blocks; trellis encoding the interleaved data in a trellis encoder; and transmitting a transmission frame including the trellis-encoded data, wherein the transmission frame includes a plurality of sub-frames, wherein the second channel data includes information indicating a current sub-frame number within the transmission frame, wherein a payload of the RS frame includes 187 transport packets of the mobile data, and wherein a row of the payload of the RS frame includes a transport packet of the mobile data, the transport packet including a 2-byte header.
