Abstract
A transmitting system, a receiving system, and a method of processing broadcast signals are disclosed. The method for transmitting a broadcast signal includes 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, 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, forming mobile data packets including data in the data group and, 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.
