    Abstract: Digital broadcasting transmission and reception devices and methods thereof are provided. The digital broadcasting transmission device includes a randomizer which randomizes a dual transport stream including a normal stream and a robust stream, a supplementary reference signal inserter which inserts a certain supplementary reference signal into a stuffing region included in the randomized dual transport stream, a Reed-Solomon (RS) encoder which adds a parity into a parity region included in the dual transport stream, a robust processor which configures a new dual transport stream by convolution-encoding the robust stream among the dual transport stream, an interleaver which interleaves the configured dual transport stream, a trellis encoder which trellis-encode the interleaved dual transport stream, and a modulator which transmits the trellis-encoded dual transport stream. Accordingly, a sub-channel can be provided in which the robust data and the supplementary reference signal will be transmitted.

    Abstract: Disclosed is a digital broadcasting transmission/reception system having an improved reception performance and in a signal-processing method thereof. A digital broadcasting transmitter comprises a TS stream generator for inputting robust and normal packets having stuff bytes in predetermined positions and generating dual TS stream by inserting the robust packets between the normal packets; a randomizer for randomizing the dual TS stream; a stuff byte exchanger for replacing the stuff bytes of a randomized data streams from the randomizer to a predetermined known data; and an encoder for encoding a data streams to which the known data is inserted. Accordingly, the present invention detects the known data from a signal received from a reception side and uses the detected known data for synchronization and equalization, so that the digital broadcasting reception performance can be improved at poor multipath channels.
