- About 768 or 752 pixels is fine enough for EVERY PAL picture, so you might
- define
- it that way (752x576; vertical/hor blanks not included).

- S-VHS uses twice the number of vertical lines (400, instead of 200! for
- standard VHS).
- Beside that, it seperates the luminance and chroma signals, making for better
- picture clarity/sharpness (composite video has interfering color and
- luminance
- signals sometimes; just watch a VHS).
