NTSC = National Television System Committee. Description is correct.

PAL = Phase Alternate Line. A NTSC-derivative color system in which the
phase of the color reference is alternated on every other line, which also
results in an alternation of the color phase of the same line on alternate 
scans of the same field. The resulting "averaging" effect reduces the
visibility of color phase errors (such as caused by antenna response and other
factors) to the point that TVs receiving any PAL system signals (that I know
of) do not require (or have) a "tint" or "hue" control, as on NTSC systems.

There is also another system in use in France called SECAM (this one I don't
know the meaning of the letters on. It's French, and since I don't speak 
French, I never bothered to find out. Probably couldn't properly print it on 
an ASCII terminal anyway 8-). ) which is totally unlike either of the above
systems.

Hope this helps.
