A digital broadcast transmitter includes a block processor encoding mobile service data at a coding rate of 1/H and first interleaving the encoded mobile service data, wherein H is an integer equal to or greater than 2, a deinterleaver deinterleaving the first-interleaved mobile service data to output a first data group, an interleaver second interleaving the first data group to output a second data group including the mobile service data, a trellis encoding module trellis encoding data of the second data group, and a multiplexer multiplexing the trellis-encoded data with segment synchronization data and field synchronization data, wherein the block processor is concatenated with the trellis encoding module.
