    We propose an MPEG-2 decoder with down-sampling in the Discrete Cosine Transform (DCT) domain for fast transcoder. It resizes images in the DCT domain before taking motion compensation (MC). After resizing the images, the motin compensation in the DCT domain (MC-DCT) is performed to the down-sampled image. If the MC was performed with a half-pixel precision in a full resolution image (N TIMES N)
