View Full Version : question about NTSC format

February 19th, 2010, 06:24 AM
I am sorta confused about the digital switch that occurred last year in regards to NTSC no longer being used in the United States.

I currently have a HD homerun that I would like to set up. But in addition to this I would like to purchase a couple tuner cards to tune SD content. What do I need to be purchasing? Will a tuner card that supports NTSC be sufficient, Or do I need to be looking for ATSC cards?

Thanks in advance for all the help.

Nobody knows this. Sorry for being impatient. Really curious though.

I would think for sure that someone on this board knows the answer to this.

I have read in various places that the old analog NTSC standard is no longer being broadcasted in the U.S. as of June 11 2009. My understanding is that it has been replaced with the ASTC standard.

Is my understanding correct?

Or better yet...

Does anyone have an NTSC card that still picks up channels?

I am sorry if I am a little grumpy but someone around here has to know the answer to this question.

Does your NTSC card work?

My understanding (from elsewhere in the world) is that analogue ntsc transmissions are on the way out, if they haven't been cancelled already.

Again my understanding is that you need an atsc card, or maybe something else if you are using cable.

Try the mailing list for more definitive answers. I guarantee you will get an answer there within an hour or so.

nickrout is correct, there is no more NTSC broadcast over the air in the US. Those airwaves are going to be used for other purposes now.
For over the air, only digital tuners work.
Analog tuners may still be used for some cable providers.

Thanks guys for confirming this. If you wouldn't mind nickrout, could you please give me a link to the mailing list. I am not exactly sure what that is...

But I assume you have found those pages via google by now anyway.

The Doom9 forum might also be helpful.

I agree, the older "analogue" system seems to be on the way out. I'm wondering how many of my friends and acquaintances will be completely baffled when the PAL-based TV channels get turned off some time in the next few years here in Porirua! I've had a Freeview (http://freeviewnz.tv) box for over a year now, and other than a couple of shows I record in the small hours of the morning for delayed viewing I tend to use it more for viewing than the analogue tuners in my TV and other gadgets.

Personally I have never had analogue reception for ages. Lived in a no signal area, then got sky, then been doing mythtv with freeview satellite ever since it started. (No longer have sky, prefer to keep my money in my pocket and/or spend it on more frontends.)
