Ques: Which Pal setting to use for RF Output.

[yogi]

Hello Group members.

I have set up my STB and was wandering which of the PAL settings would
be most appropriate for Queensland, Australia. The choices I have for
RF Output are Pal G, Pal I and Pal K.

If it helps, the STP I am referring to is the Topfield TF4000T.
A very nice piece of equipment, my other unit it the Lenoxx STB500.

Cheers

AIUI Australia uses PAL B/G (in common with most of Western Europe,
excluding the UK and RoI who use PAL I and France who use SECAM L) I'm based
in the UK - where we use PAL I!

(The PAL B standard is for VHF, PAL G is for UHF - in case you were
wondering)

The main difference between PAL G and PAL I is that the sound subcarrier(s)
are on different frequencies.

Hello Steve

I set it to Pal G in the absence of a B/G setting. I didn't notice
any difference between any or the settings, so I guess I will have to
wait a see how it goes. Thanks for your reply.

Yep - I was clearer in my first draft reply, but over edited before posting!

Most devices don't have a PAL B RF output - as they output in the UHF rather
than VHF band (PAL G is UHF, PAL B is VHF). Channel 36 used to be pretty
much the standard for RF output from modulators in the UK. (PAL I is UHF
only in the UK - though I believe other regions use it for VHF)

If you don't notice a difference between the three it could be for a couple
of reasons :
1. You aren't using the RF output but instead using a SCART or
composite/s-video/component/RGB connection (apologies if this is an insult
to your intelligence!)
2. Your TV set is multi-standard and thus happy to automatically select
between PAL G, I and K when presented with such a signal (some sets are
happy to cope with different audio spacings - especially the low volume high
end stuff, as it is cheaper for manufacturers to make and support a couple
of multi-standard models rather than many different models for each
different territory)
3. The set top box ignores the software setting and only outputs PAL G
anyway (but has support for multiple output standards for other models
running the same software)

Hello

The difference between PAL B and G is not VHF/UHF. It is 7/8 MHz
channels. PAL B and G are identical apart from the fact that PAL B
occupies a full 7 MHz channel and PAL G has a 1 MHz unused portion at
the top of the channel.

Australia uses PAL B at both VHF and UHF (only country to do so).
Europe uses PAL B at VHF and PAL G at UHF. The convention got a bit
confused when the Iron curtain fell and a number of Eastern European
countries converted from SECAM to PAL. As they had 8 MHz VHF channels
they used PAL G at VHF. They coined a new PAL B1 nomenclature to refer
to PAL G at VHF. An unnecessary confusion unfortunately.

G'day Steve

You are correct in your powers of deduction, The TV is in fact
connected through a Scart to S-Video connection. I will have to play
around with the Colour, Contrast, Brightness and Sharpness to get the
picture quality as natural as I can.

At the moment I have the TV connected to the scart connector of the
Topfield TF4000T and I have the VCR connected to the composite
connector, so as you have pointed out, I don't really have any issue
with RF Output at all. I am thinking of replacing the VCR with a DVR
in the near future.

And as for your reply being a possible insult to my intelligence, not
at all, I thank you for your reply and your assistance in sorting out
my confusion. Informative posts like yours will not only answer my
question but possibly others who didn't understand why there system is
doing what it is doing.

My TV was a top of the range unit when I got in around 2.5 years ago.

Thanks Ray - I conflated the fact that Western Europe uses B on VHF and G on
UHF - and forgot (I was dimly aware) that the channel spacing also differs
between B and G.

Ah - every international TV standard list I have seen gets this wrong - as
they state PAL B/G as the Aus standards.

Hmm - I guess the historical assumption that G=UHF and B=VHF is very strong
in Europe - even if it is technically not the case.
