In addition to the different fps rates, there is a difference in resolution
between PAL and NTSC. In standard 4x3 aspect ratio, PAL has 720x576 pixels,
and NTSC has 720x480. That's 20 percent greater horizontal resolution for
PAL over NTSC, but I don't know the history of why this spec diverged
between the two systems.
