Abstract: Disclosed is a digital broadcasting transmission/reception system having an improved reception performance and a signal-processing method thereof. A digital broadcasting transmitter comprises a randomizer for inputting dual TS stream consists of robust and normal packets having stuff bytes inserted in predetermined positions and randomizing the dual TS stream; a stuff byte exchanger for replacing the stuff byte of a randomized data stream 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.

Abstract: The present invention relates to a method for enhancing an image quality by saturation. The method includes the step of: determining a minimum gain value ‘SatGainMin’ and a maximum gain value ‘SatGainMax’ of a gain value ‘PGain’ of a pre-amplifier; defining a first to a third ranges based on the ‘SatGainMin’ and the ‘SatGainMax’; determining whether a currently used saturation value ‘USat’ is equal to or greater than approximately 1; determining whether the ‘PGain’ is less than the ‘SatGainMin’; performing saturation by using a value in the first range as an actual saturation value ‘ASat’ when ‘PGain’< ‘SatGainMin’; determining whether the ‘PGain’ is equal to or less than the ‘SatGainMax’; performing saturation by using a value in the second range as the ‘ASat’ when ‘SatGainMin’?‘PGain’?‘SatGainMax’; and performing saturation by using a value in the third range as the ‘ASat’ when ‘PGain’>‘SatGainMax’.
