Digital broadcasting receiving system and method thereof

The digital broadcast receiving system is disclosed. The system includes a first processor restoring normal stream data from the turbo stream and an equalizer, the equalized dual transmission stream equalized by the demodulator, the demodulated dual transmission stream and demodulating the received dual transmission stream including a normal stream and to restore the turbo stream data from the equalized dual transmission stream and a second processing unit for erasure decoding. Accordingly, it is possible to improve reception performance of the transport stream including a turbo stream. Dual transport stream, the turbo stream, the erasure decoder
