A digital TV receiver and a method for receiving a digital TV signal are disclosed, in which timing recovery and segment synchronizing signal recovery are independently implemented and VSB demodulation is digitally implemented. The digital TV receiver includes: an A/D converter and demodulator converting VSB modulated signals to digital signals and demodulating the digital signals in a VSB mode; a resampler performing interpolation to reduce errors between the signals digitalized by the A/D converter and demodulator using a timing error of current symbols; a timing recovery unit obtaining the timing error of the current symbols from the output of the resampler and outputting again the obtained timing error to the resampler; an equalizer equalizing a signal included in the output of the resampler using segment and field synchronizing signals as training signals; and a synchronizing recovery unit recovering the segment and field synchronizing signals from the output of the equalizer and outputting again the recovered synchronizing signals to the equalizer.
