Abstract
A system for transmitting a digital broadcasting signal includes a supplementary reference signal (SRS) inserter receiving a dual transport stream in which a normal stream and a turbo stream are multiplexed, and inserting an SRS into a stuffing region provided in the dual transport stream, a Reed-Solomon encoder encoding the dual transport stream having the SRS inserted therein, an interleaver interleaving the encoded dual transport stream, a turbo processor detecting and encoding the turbo stream from the interleaved dual transport stream, stuffing the dual transport stream with the encoded turbo stream, and compensating 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, which can robustly process a turbo stream included in the dual transport stream and easily confirm the channel state between a transmitter side and a receiver side.
