Abstract:
1. A method for transmitting a broadcast signal in a transmitter, the method comprising; encoding mobile data for forward error correction (FEC) to build a Reed-Solomon (RS) frame; dividing the built RS frame into RS frame portions; dividing the RS frame portions into Serially Concatenated Convolutional Code (SCCC) blocks; mapping the SCCC blocks to data blocks and scalable data blocks, the data blocks and scalable data blocks corresponding to a plurality of data segments, wherein at least one of the SCCC blocks includes one of the data blocks and one of the scalable data blocks; encoding signaling data including a header and a payload; forming data groups including the data blocks and the scalable data blocks, wherein specific data blocks of the data blocks in the data groups include signaling data having information for a number of ensembles, the ensembles being a collection of services transmitted through the data groups; interleaving data in the data groups; and transmitting the interleaved data during slots in a transmission frame, wherein the interleaved data includes a plurality of data segments, and wherein at least one of the plurality of data segments includes a part of one of the data blocks and a part of one of the scalable data blocks.
