    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： A digital broadcasting transmission and reception system includes a digital broadcasting transmission apparatus and a digital broadcasting reception apparatus. The digital broadcasting transmission apparatus that includes a robust processor that codes a robust stream of a dual transport stream where a normal stream and the robust stream are combined. The robust processor includes a demultiplexer (DE-MUX) that separates the normal stream and the robust stream from the dual transport stream; a robust encoder that appends a parity to the separated robust stream; a robust interleaver that interleaves the robust stream having the appended parity; and a MUX that combines the interleaved robust stream and the separated normal stream. The digital broadcasting reception apparatus includes a robust decoder that decodes a robust stream of a dual transport stream where a normal stream and the robust stream are combined. The robust decoder includes a first decoder that trellis-decodes the robust stream; a robust deinterleaver that interleaves the trellis-decoded robust stream; a second decoder that convolution decodes the deinterleaved robust stream; a robust interleaver that interleaves the convolution-decoded robust stream; and a frame formatter that adds decoded data of the second decoder to a part that corresponds to a position of the robust stream of a frame where the normal stream and the robust stream are mixed. Accordingly, a receiver of a simple structure can be provided.
