how d'ya get the stopper out?

Pull it it's only got about 1 bar holding it in...

How big a stopper ? For more than a few square inches that's a lot of

A tube to space won't suck air up. Gravity would hold the air in the
tube down, just like it does the rest of the air.

Bummer. I thought I was onto something.

Don't despair Max. The moon is zero gravity, so if the other end of the
tube were on the moon it could well work.

Count me in. This time next year we will be millionaires.

Yes, and it took the IBA a while to relax the rules on the use of that,

Not zero gravity on the moon - just less than the earth. Don't you
remember pics of the astronauts leaping?

PAL is a very robust signal. It can be inadvertantly distorted by
all manner of circuits and equipment yet still yield very acceptable

smallest amount of distortion can lead very quickly to very poor

or over long transmission distances.

You'd have to explain clearly what you mean by 'distortion' before I
could comment on that.

Slainte,

I deliberately used the word distortion as an all emcompassing term.
Name any distortion that can be applied to a video signal: amplitude
variations, group delay, incorrect application of cable equalisation,
differential phase and gain, Non-linearity. Apply small amounts of any
of these to a PAL signal and as most likely you will get acceptable
(i.e. usable) results at the 'far end'. Apply these to three matched RGB
signals at the start of a 3 channel signal path - differentially - and
you will most likely end up with a mess in very short order.

Ok, so you meant "any kind of process that can alter waveforms shapes or
timings". The difficulty with that is that is is so vague and sweeping that
it comes back to the comment I've been making. That this becomes a general
'belief system' that is presented as a 'reason'. A conclusion is not a
reason. Evidence is a reason.

Many of the linear processes are correctable by linear means, of course.
Non-linear is more difficult, particularly when gross. But non-linear is
also more problematic with analogue multiplexed signals.

Can I ask you Jim, have you worked as a broadcasting engineer?

Nope. Nor have I said either that what people are saying is 'wrong' or that
something like RGB or a linear matrix of that would be 'better'. I'm trying
to find out the real reasons for the *conclusions* people are stating.
Doing this because asking such questions often exposes where people are
simply taking for granted what they regard as 'facts'.

Above said I do have a track record in devising and engineering high
performance measurement and signal processing, etc, systems. This often
involved asking people why they have used existing methods before
developing a much better alternative. Asking questions is a way to prompt
all concerned with open minds to learn and develop. Even if the outcome is
to decide that what they have been doing is fine. :-)

It also often involved a stage where some of the 'experts' said that
what I and the people I worked with proposed with would not do 'better'
than pre-existing methods. Indeed, often told what we'd proposed was
impossible... until it worked. They then quietened down and joined
the queue for the kew kit. ;- So although there is no magic wand or
guarantee I tend to be curious about the reasons behind what people
say. They may believe it, and their experience may support their
belief. But their experience may be pre-selected to miss some
possibilities by the nature of the relevant circumstances.

There have been many replies here from people here who have clearly
spent a lot of time in the industry and they are all making the same
points about the practicality of RGB versus PAL in a broadcast scenario,
but you do not seem to want to accept them. I assure you this is a
respectful question.

Noted. Note also what I have written. :-)

Please also note that asking someone questions to elict the *reasons* for
what they say does not equate to calling them a liar or an incompetent.
What they say may be correct. But sometimes even the 'experts' don't really
know why. And are often basing their conclusions on assumptions that could
be false.

Slainte,

Jim

On the basis that no one else has posted this, it must be new, and is
a must for this thread.
