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.

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.

My new ATI driver implies they r both NTSB. Just my 2¢ worth. Larry

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!
