NTSC or Pal?
/Col.
1. I understand Pal is 50hz and NTSC is 60. Is this Correct?
2. Presumably NTSC is better?
3. According to the manual my 28" Sony is compatible with both. Going on
the above two being correct, if I were to tell my Pioneer 737 to output in
NTSC I'd get a better picture. Is this possible?
4. Am I missing anything?
5. Please explain what.
Thanks

The refresh on NTSC may be higher but there are fewer scan lines in the
picture...therefore the "resolution" (for want of a better word) is not as
good as PAL. Though frankly when you get to DVDs (see below) NTSC disks look
just as good as PAL disks to me.
> 2. Presumably NTSC is better?
Not for broadcast I think - ever seen a TV in the States?

No...it will switch to receive whatever the source is that is being fed to
it. So, in the UK everything is broadcast in PAL. Also if you buy/record
VHS tapes those will be PAL, as will Region 2 (UK bought) DVDs. Region 1
DVDs, however, are NTSC so if you play those (which your 737 can if its been
doctored correctly) then your TV will recognise that its being sent an NTSC
signal & switch accordingly.

Not a lot except as above - basically you don't choose which system to use -
the TV reacts to what's being fed to it.

Run out of things to say now........(!)

I too have a multiregion DVD player (Pioneer) and NTSC-capable TV. I
have found that with the DVD player set to output NTSC for NTSC DVDs the
picture is not as good as when I set it up to always output PAL. The
pure NTSC picture seems subjectively more plastic than the PAL picture
from the same region 1 DVDs. Look particularly at skin tones which look
less natural.
When set to give PAL output, the output from NTSC discs is not actually
converted to PAL - you cannot, for instance, record the picture onto a
VCR. It is often known as quasi-PAL or pseudo-PAL and is still NTSC but
with enough of a conversion to allow a PAL TV to display the picture.
Those more technical than me will elucidate on this one. Apparently the
signal displays some of the inherent advantages of PAL over NTSC.
Hope this helps.

Carrier frequency.
NTSC uses a frequency of 3.57 which is 525 Lines @ 60Hz
PAL uses a frequency of 4.43 which is 625 @ 50Hz.
Converted NTSC-PAL = Quasi Pal (sometimes called Pal-60 or NTSC 4.43)
My Pioneer DVD can output NTSC (r1) DVD's in Pal-60. This can cause
problems on some non Multi-standard TV's.
Some simply cannot "Lock-on" to the converted PAL-60hz Signal, displaying a
scrolling image.
Some other TV's when feed an NTSC signal, will display a stable picture, BUT
ONLY IN B/W.
most purest will agree, that it is better to leave the signal unaltered.
PAL output as PAL, NTSC output as NTSC. (You may need to adjust your TV
colour settings slightly, for NTSC material.)
I on the other hand have found that I prefer the Converted PAL-60 Picture.
Hope this helps

That is not actually the case. You have to remember that the disc does not store
as PAL or NTSC, and so there is no 'conversion' occuring. PAL actually has a
better colour system, and actually as you noticed, you get the best output from
PAL-60 rather than NTSC.
Of course, what you should be doing (ob: unless you have a toshiba tv) is
viewing in RGB anyway....

times a second (50hz)
NTSC - system used in US, Japan etc. - uses 525 lines updated 60 times a
second (60hz)
The only reason you would want your DVD player to output in NTSC was if you
were playing a region one DVD...

I watched my first Region 1 disc last night (Apollo 13) and spent ages
trying to get the picture right (hence my Pioneer 737 owners posting further
up). As you said Kevin, it looked plasticy. I think I'll do what you do -
generally buy Region 1's for the extra's and uncut bits, but watch them in
PAL 60.
I think I understand now. But what was that about;
"Of course, what you should be doing (ob: unless you have a toshiba tv) is

Er. True for VHS and laserdisc which use composite (or svideo) with
NTSC or PAL encoding. Completely untrue for DVD which uses YUV
component encoding. This has to be converted to either PAL coding
(which has a wider colour footprint) or NTSC (which is poorer) at
whatever frame rate the disc was encoded (525/60Hz or 625/50Hz). If
you *must* use composite or svideo, then PAL60 will be `better'. Of
course, normally you will not want to use either of those. You'd use
RGB or YUV (which may get you progressive scan as well).
YUV would be the ``unaltered'' output from a DVD. There aren't many
low end TVs with component inputs (in the UK), though.
I'm no longer amused by reviews in HCC that go on about watching
region 1 DVDs in their ``purest'' form using NTSC output and
criticising DVD players for only having PAL50 and PAL60 output (no
NTSC). What nonsense.
Gixer750> (You may need to adjust your TV colour settings slightly,

You cannot adjust the colour on most TVs if you are using RGB. The
exception is 100Hz TVs that sample the inputs and then regenerate an
approximation of them for display de-interlaced at 100Hz.
If you have a Toshiba TV, then 525/60Hz material will look best using
YUV or svideo, and not RGB. And of course there are TVs that can
handle composite NTSC, but not PAL60 - as well as vice versa.

Basically, as has been said a fair bit on this newsgroup (so a search on
google may help you), Toshiba televisions do not handle NTSC very well when
using RGB. They do have a very good s-video picture though.
In the case of your proposed set-up, i would use the Digibox set up to the
RGB scart (with NTSC358 enabled to correct picture shift) and the DVD
connected to the s-video scart.

Because it seems that RGB on newish Toshibas is more 'interfered' with than
S-Video, - no idea why, but everyone reports a better picture with S-Video on
them!

Just to add that there are no problems at all when viewing PAL via RGB so
the digibox will be fine.

concerned. On low end TV's, such as a Goodmans one I brought that accepts
PAL 60 or NTSC it detects a NTSC signal and gives you a HUE control which
improves the colour contrast no end. Skin colours are more noticable and
natural in PAL, saying that adjusting hue if you have it get a decent result
too. Take ya pick really!
