ABSTRACT:
In an image down-sampling transcoding method, by reducing an MPEG SP (simple profile) video bit stream having a CIF (Common Intermediate Format) size into a half in image size in a pixel domain, the video bit stream is converted into a H.264 BP (Baseline Profile) video stream having a QCIF (Quarter CIF) size. Accordingly, it is possible to down-sample an image from MPEG-4 to H.264 at a high speed.
