Patent ID: 8619876

Claim:
A method of processing a digital broadcasting signal, comprising: preparing a first area for parity insertion with respect to a dual transport stream (TS) which includes a normal stream multiplexed with a turbo stream; interleaving the dual TS which includes the first area; detecting the turbo stream from the interleaved dual TS, exclusively encoding the detected turbo stream, and stuffing the encoded turbo stream in the dual TS for turbo processing; deinterleaving the turbo-processed dual TS; transmitting, by a digital broadcast transmitter, the deinterleaved turbo-processed dual TS; receiving, by a digital broadcast receiver, the transmitted dual TS; demodulating the received dual TS; equalizing the demodulated dual TS; decoding the normal stream of the equalized dual TS to recover a normal data packet; and decoding the turbo stream of the equalized dual TS to recover a turbo data packet.
