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 mobile data belonging to an ensemble including a mobile service is Reed Solomon-cyclic redundancy check (RS-CRC) encoded according to a RS frame mode, wherein the encoded RS frame is separated to a plurality of frame portions; dividing the plurality of frame portions into serial concatenated convolutional coding (SCLC) blocks according to a SCLC block mode, performing outer encoding of SCLC on data in the SCLC blocks according to a SCLC code mode, and outputting data blocks including the outer-encoded data; encoding signaling information for the mobile data, the signaling information including first channel data and second channel data, wherein the first channel data delivers binding information between the mobile service and the ensemble for rapid service acquisition, and the second channel data includes information indicating a current sub-frame number within a transmission frame; forming a data group including the encoded signaling information, known data sequences and the data blocks, wherein the data blocks correspond to a plurality of data segments in the data group; 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 SCLC block mode for identifying a relationship between the plurality of regions and the data blocks; and transmitting the transmission frame including the interleaved data, wherein the data group is carried by a parade and the data group in the parade is delivered within one of slots, the slots being equally divided among sub-frames of the transmission frame.
