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 Reed-Solomon (RS) frames; dividing the built RS frames into a number of RS frame portions; dividing one of the RS frame portions into Serially Concatenated Convolutional Code (SCCC) blocks; performing convolutional coding on data in the SCCC blocks according to a SCCC code mode; mapping the SCCC blocks including the convolution-coded data to mobile data blocks according to a SCCC block mode which identifies relationship between the mobile data blocks and the SCCC blocks; forming a data group including the mobile data blocks, wherein the data group includes a plurality of regions, the plurality of regions includes the mapped mobile data blocks corresponding to a plurality of segments; forming mobile data packets including data in the data group; multiplexing a specified number of the mobile data packets, a first scalable number of the mobile data packets, and a second scalable number of main data packets; wherein one region of the plurality of regions includes the first scalable number of the mobile data packets.
