- Dong-Lok is of course right. I got this started by describing the formats
- accepted by two hardware MPEG implementations. Somehow I forgot I got my
- numbers screwed up and worked forward from the 640x480 VGA numbers rather
- than the CCIR numbers. The chipsets I mentioned do indeed take the real
- MPEG SIF resolution (352 x 240) and the Px64/JPEG CIF resolution (352 x 288).
