Can't remember exactly what I was taught it being so many years ago, but
it was something like:-

NTSC gives the best studio pictures.
PAL records best.
SECAM transmits best.

Or perhaps any combination of the above. ;-)

PAL was used in Europe to minimize the effects of non-constant group delay
in the European distribution system. (PAL is less-sensitive to this, at the
expense of chroma desaturation.) The US microwave system didn't have this
problem, and NTSC's designers did not see any inexpensive way to take
advantage of PAL (for such things as automatic hue correction), so it was
dropped.

NTSC also has wider color bandwidth, and the color signals match the way the
eye sees color.

NTSC and PAL are pretty much Tweedle-dum and Tweedle-dee, though -- they're
fundamentally the same thing, and it's easy to convert from one to the
other. SECAM is a classic example of truly lousy design. It makes recording
and transmitting the signal simple, while requiring a more-expensive
receiver. Not good.

Would you like a detailed explanation? Or are you afraid of the truth?

In what ways? Be specific. (Pardon me while I go off to take a nap.)

You don't know what the hell you're talking about. Put up or shut up.

PS: You might also look up the definition of "sophistry".

Considering the 1960's attitude that TV sets (and TV reception) was something
to be limited and controlled, it's wonderful. :-)

The US never had a tax on TV sets.

Before VAT the UK (and most of the rest of the world) had a luxury tax
on TV sets, and the UK has a TV Tax. It's 142 quid per year, which is enough
to buy a decent TV set.

Here it's 650 NIS a year, more than the cost of a 21 inch CRT TV, but due to
the high taxes (besides VAT) on TV set's not quite the cost of one. You can
buy a 21 inch "full hdtv" computer monitor with VGA and DVI connectors on
it for less, but the moment you add a composite, S-video or HDMI jack*, and
or a tuner, it doubles in price.

Geoff.

* Yes I know an HDMI jack is a DVI jack with sound added, but DVI is a computer
interface therefore a business/educational device, HDMI is an
entertainment device.

You can prevent the 'four strikes and you're out' happening by running
