ABSTRACT:
HDTV video decoder circuit is disclosed, which has an 1/4 size frame memory for a progressive scanned or interlace scanned video and yet can conduct IDCT and motion compensation to fit to the reduced frame memory size, which, in comparison to a conventional MPEG-2 video decoder which uses a 4.times.4 IDCT that requires 1/4 frame memory in encoding an interlace scanned image into frame picture only to lose field information of the image resulting in a significant damage to the picture quality, facilitates to maintain the field information as it was resulting in an improvement in the picture quality.
