"C-Cube Microsystems has a lot to gain by folks wanting to decode then re-encode-since they make the chips that do the encoding and decoding. Their new DVxpress-MX chip may be the world's first all-digital, mixed format compression chip for MPEG-2 (4:2:2 and 4:2:0) and DV25 (as well as another model that adds DV50) (4:2:2, 4:2:0 and 4:1:1), but in order to do the conversion, the single chip converts the compressed video to digital baseband-with a transcoding latency of seven to eight frames. Dr. Feng-Ming Wang, C-Cube's general manager for the PC/Codec division believes that "the MPEG domain is always limited" and that baseband provides the "least possible problems."
