File Format*

[John Q. Smith]

I realize that this is slightly off topic, but does anyone know what type of
format Windows uses when using a TV Tuner card while connecting to normal
cable TV via coaxial cable?
I am looking at buying a TV Tuner card, but it states that it only supports
NTSC video format only.

Re: File Format*

I know enough to tell you that the NTSC standard is used for video here in
the USA, and that the PAL standard is used in Europe, and in some other
countries.

But I don't know about the upcoming format changes with HDTV coming around
next year, and whether that will be a problem.

It depends on what type of TV signal you receive in your area.
The TV Tuner card will turn that TV signal into video that WinXP can
display on your screen.

Good Luck.

FYI: The HDTV formats are different between the US and Europe. The US
format has retained its 30 frame per second format from (the original) NTSC
and the European format has retained the 25 frame per second format. This
was completely unnecessary as the deployment of Plasma and LCD displays has
rendered the adoption of the mains frequency as the frame rate redundant.
The practical upshot is the US HDTV requires 20% more space to record it.

This doesn't have anything to do with Windows, which knows nothing
about video formats, but (mainly) with where you live.

NTSC has been the TV signal format in the US for as long as broadcast
TV has existed. In Europe (and Asia?) they use a different
(incompatible, of course) standard called PAL.

Broadcasts in NTSC format will disappear next February, all broadcasts
will then be in digital format. If you're on a cable TV system, you
will probably still be able to get NTSC analog signals through them.
Converter boxes are also available.

Video tapes and non HD video DVDs are recorded in NTSC (or PAL, if
you're not in North America) format. DVDs are likely to stay around
for quite awhile, tapes will probably go away sooner.

Look up any of these terms in Wikipedia if you want to know more.

NTSC only means it will NOT received DTV (Digital broadcast signals).
If you want to get off-air programming, forget it. Get one with a DTV
digital capable receiver/tuner.


NTSC: Standard North American 4:3, non-DTV format. Also known as
analog TV.

ATSC: North American 16:9/4:3 format for DTV reception. Also known as
digital TV.

Wikipedia.com has some good explanations.

http://en.wikipedia.org/wiki/Digital_television

http://en.wikipedia.org/wiki/Analog_television

You need a card that will handle Digital TV (DTV) as many of the analog
stations are going dark between now and Feb 09.

Rubbish! Broadcast TV started in 1926 using the 30 line system. The NTSC
system wasn't devised UNTIL 1941. Meanwhile broadcasting had also taken
place using the 240 line and then the 405 line systems.

The digital broadcast parameters (in the US) are still based on the NTSC
standards. If you watch them on an analogue TV then the digital signal
resolves to a standard NTSC signal to be displayed. If you watch them via a
digital link to the TV (DVI or HDMI) then the video format standards are
still firmly tied to the NTSC specification - its just given a confusing
identifier 480i/30 (which also describes NTSC).

ROTFL!! You're absolutely right! But not many people were watching
back then. I think I can safely say that NTSC has been the standard
since TV became even remotely mainstream.

Interesting, I wasn't aware of that.

NTSC (or System M to give it its formal name) is almost exclusively used by
some tin pot little back water on the other side of the Atlantic (with one
or two pockets of resistance in the far east). The civilised world uses the
625 line system with PAL colour (SECAM in France and Russia) also described
as 576i/50. ;-)

What comes a a minor mystery, is why the US clung onto their 30 frame/sec
rate when adopting HDTV. There was no technical reason to do so.

In the systems used before NTSC, I managed to omit the oddball French 819
line system. I mean the system was oddball, not the French. Come to think
of it, scratch that last sentence.

Cause we don't like the flicker of the 25 frame/sec rates!!
I mean (as yet another example), with a 50 Hz line frequency over there, it
takes some of us a bit of time to get readjusted to the slightly flickering
incandescent lights over there (some of us have quick visual response times,
with low latency).

With Plasma and LCD TV sets, what flicker would that be?

I don't know, since I don't have either of those!
