Provided are a video reproduction apparatus and method capable of effectively post-processing a video signal using a motion vector, a post-processed video signal and a difference video signal. The method includes the steps of (a) variable length decoding the compressed video signal to detect quantized discrete cosine transform (DCT) coefficients and a motion vector, when the compressed video signal is input as a bit stream; (b) inversely quantizing the quantized DCT coefficients detected in (a); (c) performing an inverse DCT (IDCT) on the DCT coefficients obtained in (a) to detect a difference video signal; and (d) selectively performing post-processing on the decoded video signal, based on the motion vector detected in (a) and the characteristics of the difference video signal detected in (c). |
