I don't have the time to discuss this at length, but NTSC's unfortunate
reverse-acronym was the result of poor studio standards, and is not
inherent in the system. PAL incorporated phase alternation to partly
compensate for transmission problems (non-linear group delay) in Europe.

IIRC, nowt to do with studios, but the transmission process. Hence the
tint control on NTSC sets which is absent on PAL ones.

The implication of "never twice the same color" was that there was something
inherently unstable in the system.

The US had high-quality microwave transmission systems with excellent timing
and group delay characteristics. Europe did not.

To those in the US... When was the last time you adjusted the hue control on
your analog TV?



If I remember my BBC training correctly, NTSC gives theoretically better
'studio' pictures than PAL.

Yes, because it has wider chroma bandwidth. Other than that, they are
essentially the same system.
