Digital broadcasting transmission system and method thereof

A digital broadcasting transmission method, comprising:

• encoding a dual transport stream (TS) which includes a normal stream and a plurality of turbo streams that are multiplexed together;
• interleaving the encoded dual TS;
• detecting the turbo streams from the interleaved dual TS and encoding the detected turbo stream;
• and
• pseudo2 (P-2) VSB coding the turbo-processed dual TS, and then performing trellis encoding;
• and
• multiplexing the trellis-encoded dual TS by adding a field synchronous signal and a segment synchronous signal thereto.

A digital broadcasting transmission system, comprising:

• an RS encoder to encode a dual transport stream (TS) which includes a normal stream and a plurality of turbo streams multiplexed together;
• an interleaver to interleave the encoded dual TS;
• a turbo processor to detect the turbo streams from the interleaved dual TS and to encode the detected turbo stream;
• and
• a trellis encoder to pseudo2 (P-2) vestigial sideband (VSB) code the turbo-processed dual TS, and, then, to perform trellis encoding;
• and
• a main multiplexer (MUX) to multiplex the trellis-encoded dual TS by adding a field synchronous signal and a segment synchronous signal thereto.

A digital broadcasting reception system, comprising:

• a demodulator to receive a dual transport stream (TS), including a normal stream and a turbo stream, transmitted from a digital broadcasting transmission, to detect a synchronization according to the synchronous signal added to the baseband signal of the TS, and to demodulate the TS;
• an equalizer to equalize the demodulated dual TS by compensating for channel distortion due to multipaths of the channel;
• a turbo decoder to decode the equalized turbo stream of the dual TS;
• a viterbi decoder to correct errors of the normal stream of the dual TS, to decode error-corrected symbols thereof, and to output a symbol packet;
• a receiver multiplexer (MUX) to multiplex the error-corrected normal stream and the decoded turbo stream;
• deinterleavers to deinterleave the viterbi-decoded normal stream and the decoded turbo stream, both of which are then RS-decoded, derandomized, and outputted;
• a parity eraser to remove a parity bit, which is appended to the deinterleaved turbo stream;
• a second derandomizer to derandomize the turbo stream from which the parity bit is removed;
• and
• a second de-MUX to demultiplex the turbo stream.
