Abstract:
1. A system for transmitting a digital broadcasting signal, comprising: a supplementary reference signal inserter receiving a dual transport stream having a multiplexed normal stream and a turbo stream, and inserting a supplementary reference signal into a stuffing region provided in the received dual transport stream; a Reed-Solomon (RS) encoder encoding the dual transport stream having the inserted supplementary reference signal; an interleaver interleaving the encoded dual transport stream; a turbo processor detecting and encoding the turbo stream from the interleaved dual transport stream, encoding the detected turbo stream, stuffing the dual transport stream with the encoded turbo stream, and compensating the stuffed dual transport stream for a parity corresponding to the encoded turbo stream; and a trellis/parity corrector performing a trellis encoding of the dual transport stream processed by the turbo processor.
