Does the HDMI satndard have PAL and NTSC flavours?
In other words, say I caonnect a PAL DVD to an NTSC HD TV using HDMI,
will it work?

The answer to the first question is yes.
The answer to the second question is no. The TV must have PAL cabability
for the PAL DVD to work.

Make that capability not cabability. :) :)

If by "flavour" you mean differences in physical construction of the
cable assembly or connectors for PAL or NTSC, the answer is no. But
if you mean there is a difference in the signal going across, then
the answer is yes. Unless your PAL DVD player can convert to another
format (some multi-standard models can do that), the output will be
in the PAL format. If the TV only handles NTSC, that obviously will
not work.

But technically speaking, "NTSC" is an analog standard that specifies
how to carry color difference signals along with the monochrome analog
signal for standard definition video. HDMI is designed to carry video
in a digital form consisting of discrete monochrome and color difference
signals. This really is not "NTSC" per se, though the video being sent
may have the same frame rate and geometry as NTSC (this would make sense
for video content made in North America). Distinguishing this video
format in a digital context would be better done as "480i29.97".

Labeling a TV as "NTSC HD" also does not make sense, since HD is not
really either "PAL" or "NTSC", though frame rates for HD will generally
match either PAL or NTSC frame rates (or certain other frame rates that
are associated with motion picture production).

A TV that can do both HD (in one or more of 720p59.94 and 1080i29.97)
and SD (in 480i29.97 for the "NTSC market" ) would not require much more
to also be able to handle PAL-like digital video. You may find that
some of the more flexible TV sets or monitors really can handle video
in formats like 576i25, even though marketed in North America. Monitors
designed for computers that are adapted for TV use, particularly the CRT
type, most likely can.

If you are in the market to buy a new TV or monitor, you might want to
check and be sure the models you consider really can handle all the
video formats you want to use.

Preface - the HDMI Spec is only available to manufacturers at
http://www.hdmi.org, and its "Video Format Support" section has the
(complex) details you are seeking. Its not appropriate for me to post the
relevant section, so I'll summarize here.

NTSC, PAL and SECAM are analog standards, and as such you will not find much
direct reference to them in the HDMI Spec. What you will find is that most
resolutions are qualified as being @59.94/60Hz or @50Hz, and the general
comment is that HDMI devices should output/input the same class of
resolutions/framerates that the same device would output/input on component
video or DVI. In short, if all your analog outputs have European DTV
resolutions @50Hz, thats what you should expect in your HDMI output too. If
all your analog outputs have US DTV resolutions @59.94/60Hz, thats what you
should expect on HDMI too. The only mandatory cross-over is that @50 sink
devices need to be able to accept 640x480 @ 59.94/60 (the fallback mode that
so many video standards require).

Above and beyond the required behavior, there is nothing limiting a
source/sink device manufacturing a device with HDMI that supports all the
knowm European and US DTV resolutions/framerates.

Hello,

So a PAL DVD Player can not be used with a NTSC TV even using HDMI output from the DVD.

What about using a HD Tuner with HDMI output (from Europe) with an NTSC HD ready LCD TV?

Thanks

Hi gurus,

I have a biiiig problem here. I used to live in Colombia, and i bough a Sony bravia KDL40-XBR2 ATSC LCD. Some months later i returned to my Country in Europe and brought the LCD with me....

Now, i have a Philips DVD player i bought in Colombia that i cracked, and i'm able to see all regions DVD's.. That's ok ... but i bought a Sony bravia DVD recorder ( one of those with HDMI output and RF input) .. connected it via HDMI into the LCD and ..... the only thing that appears is :

"Unsupported signal - please check video output"

Is there any solution for my problem ..like HDMI frame rate converters ...

Pedro

HI

 

I have the same exactly problem :pfff: with my Sony bravia KDL46-XBR2 ATSC LCD that I brought from US while I was there on job assignment. Now I'm back in Europe (Poland) and can not connect any locally available PayTV satellite tuners using HDMI ports or other available ones; keep getting the same message as Pedro: "Unsupported signal - please check video output". I'm almost certain that this has to do with refresh rate at least in HDMI case (50 vs. 60 or is it 100Hz vs 120Hz) :pt1cable:. If that's the case is there a device (preferable a satellite tuner) that I can configure for "European HDMI" input and "US HDMI" output?

 

Thanks for help

 

Konrad

I'm reading all that's written, but I'm afraid the technical jargon is a bit too advanced for me to understand. Moreover, what hasn't yet been answered are the questions that matter to me. I, too, have a Sony Bravia TV. (Note to other users: if you set set-top box output to 576i / p and connect through Component cables, it should work.) Through HDMI, my Bravia won't display anything but a a little yellow box with "unsupported signal type."

What really interests me is whether ATSC or DVB "encoding" persists after it passes through my decoder (my cable box, if that's more understandable). I understand that it's not really ATSC, or DVB, but this specific scenario doesn't matter much, what does is whether or not this will leave the signal standard (ATSC / DVB) incompatibility problem unchanged.

It's a bit hard to describe what I mean as I don't truly understand this, but I'm giving it my best shot: Will the output from an HDMI cable from my DVB-C cable box be compatible with a TV with ATSC and QAM tuners? A friend of mine says it works for him, however, it doesn't work for me. I'd just like to understand how this works...

I have found the solution that works, I hope. I have ordered a product that's called scaler and what it allows me to do is to define refresh frequency on HDMI's port (input & output). The scaler is: GEFEN HOME THEATER VIDEO SCALER CONVERTER 1080P HOMETSP. There are others but I have ordered this one.

Can you post if your solution worked. I might be facing exactly the same problem if we go back to Poland.

Thanks

There is a unit specifically made for converting 50Hz Pal to 60Hz NTSC or vice versa.
Atlona AT-HD560

Thanks

Ok , this might be the answer I need to fix my " Unsupported Signal" issue where can I purchase this unit and approx how much is it if you now
Thx.
