Hey, PlayStation Players...
This has been urking me for weeks. What the heck are NTSC and PAL? I
see Formula 1 has 30fps NTSC and 24-25 with PAL. Huh...? Please
enlighten me...

NTSC is the CRT (TV) standard used in countries with 60hz current,
whereas PAL is for 50hz current. Not sure what the acronyms actually
stand for, but the upshot is that unless re-optimised PAL games run
slower than their NTSC counterparts (which is why, if you follow any
of the Nintendo 64 NGs everyone is whinging about how the UK version
runs slower and has a letterbox screen). This is why PAL F1 doesn't
run at 30fps. If the game hasn't been modified to take account of the
slower speed it means that everything runs slower and therefore your
reactions don't have to be quite as fast (hence endless discussions of
how UK gamers have it easy!)

NTSC-The United States Standard for television. It stands for
National Television Standards Committee. As Alan states, it uses
60 Hz (normal AC line voltage in the US). The frame rate is one-half
of the line voltage frequency. (Hz stands for Hertz, and is a
measurement of time.) The purpose of a 30 frame per second interlaced
rate is to reduce flicker, which is visually distracting. It has 525
lines of video per frame, though only 483 are visible on the screen.
The rest are used for timing and signals used for other purposes
(such as closed captioning.) It is the oldest standard for television
in use in the world today, thus it has become a bit archaic.
We engineers jokeingly suggest that NTSC stands for Never Twice the
Same Color. :-)
PAL-Phase Alternating Line. This is used primarily in the UK, Western
Europe, and South America. The PAL standard scans 625 lines per frame
and has 25 frames per second. Once again, this frame rate is one-half
of the frequency of their house voltage, which Alan correctly states is
50 hz. The method of phase shifting used in PAL makes for better color
hues, and by shifting on each line eliminates the flicker that made it
objectionable for use in the U.S. in the early 1950's.
