    摘要： A transport stream (TS) generating apparatus, a transmitting apparatus, a receiving apparatus, a digital broadcast system having the above, and a method thereof are provided. The digital broadcast system includes a transport stream (TS) generating apparatus which generates a multi transport stream (TS) by multiplexing a normal stream and a turbo stream having a variable coding rate, a transmitting apparatus which re-constructs the multi TS by processing the turbo stream, and transmits the re-constructed multi TS, and a receiving apparatus which receives the re-constructed multi TS, and decodes the normal stream and the turbo stream respectively, to recover normal data and turbo data. Accordingly, a multi TS, which includes normal stream and a turbo stream of various coding rates, can be transmitted and received efficiently.

    摘要： A digital broadcast transmitting/receiving system, and a signal processing method thereof, includes a randomizer for randomizing a transport stream into a specified position of which stuff bytes are inserted, a stuff-byte exchanger for replacing the stuff bytes included in data output from the randomizer with specified known data, an RS encoder for performing an RS-encoding of data output from the stuff-byte exchanger, an interleaver for interleaving data output from the RS encoder, a trellis encoder for performing a trellis encoding of data output from the interleaver, an RS parity generator for generating a parity by performing an RS encoding of data output from the RS encoder, and outputting the generated parity to the trellis encoder, and a modulator/RF converter for modulating data output from the trellis encoder and performing an RF up-converting of the modulated data. The digital broadcast receiving performance can be improved even in an inferior multi-path channel by detecting the known data from the received signal and using the known data for synchronization and equalization in a digital broadcast receiver.

    摘要： An outer encoder includes a bit detector that receives a turbo stream provided with a parity insertion region and that detects data bits from the turbo stream, an encoder that convolution-encodes the detected data bits, and a bit inserter that inserts an encoded value outputted from the encoder into the parity insertion region in the turbo stream. The encoder includes a first register; a second register, in which when a bit value is stored in the first register, a stored value pre-stored in the first register is shifted and stored; a third register, in which when a bit value is stored in the second register, a stored value pre-stored in the second register is shifted and stored; a first adder adding the input bit value, the stored value pre-stored in the first register, and the stored value pre-stored in the third register, and storing the resultant value of addition in the first register, if a specified bit is inputted; and a second adder adding the input bit value, the stored value pre-stored in the first register, and the stored value pre-stored in the second register to output the resultant value of addition. Accordingly, only the turbo stream in the dual transport stream is robustly processed.
