PAL TV Tuner

What is a PAL TV Tuner? What is it for? What does it do? My television
states that it has an optional PAL TV tuner available. I really don't
know what they mean.
Thanks for your help!

 

It for non NTSC standards. It would be of little use in the US or Canada or
Mexico.
PAL stands for Phase Alternate Line. Use google to find more info.

 

I found ancient runes from Jeff[] in the floor of
sci.electronics.basics:

It's for non-NTSC TV receiving. e.g. in Brazil, we use PAL-M.
Search Google for more info!

 

Long(ish) form:
PAL is the system of TV signals used in many parts of Europe and South
America. Here in the states, we use NTSC. A third (there are others, but
I can't think of them right now) is SECAM, used mainly in France. None
of them "play well with others". And each one, of course, uses its own
tuner, since it expects the signal to be laid out differently and/or to
be on different frequencies than those used by the other types.

Short form: If you're not using the TV in Europe, South America, or one
of the other places that transmit PAL video, a PAL tuner is nothing but
a pile of high-tech junk to you.

Hit Google for plenty of info on pretty much any of the various TV
transmission schemes/signal formats/frequency layouts that are in use
around the world.

 

AFAIK PAL-M is very similiar to NTSC that they could be used straight on
NTSC TV without problem. European PAL is the one that's drastically
different (different color carrier freq. and different scan freq.)

 

There are other explanations for the various abbreviations:

NTSC: Never twice the same colour
SECAM: System essentially complementary to the American method
PAL: Performance at last

;-)

 

Eh, I never liked PAL. It flickers too much at 50Hz while it's a lot
less noticeable at 60Hz for NTSC.

 

There are many sub variation of PAL as well....

 

PAL doesn't necessary mean the 625/50 scanning
standard; it refers solely to a color-encoding method.
It's true that it is most often seen in countries which also
use the 625/50 timing, but it's not really tied strongly
to that standard. (Both a 60 Hz variant of PAL, and
a 50 Hz NTSC, have been used!)
