ABSTRACT:
A video signal reproducing apparatus and method for adjusting a change in a horizontal synchronous signal. The video signal reproducing apparatus transforms a format of an input video signal, generates horizontal and vertical synchronous signals, and displays the video. The video signal reproducing apparatus includes a measurer, a comparator, and an adjustor. The measurer measures a period of the horizontal synchronous signal, the comparator compares the measured period of the horizontal synchronous signal with a predetermined reference range, and the adjustor adjusts a period of a clock signal for producing the horizontal synchronous signal, if the measured period of the horizontal synchronous signal fails to fall within the predetermined reference range.
