I get only FIOS internet service. If I plug the FIOS cable directly into the QAM port on my TV, will I get local TV channels (in HD)?]]>May 8th 2009 1:36PMhttp://hd.engadget.com/2009/05/08/hd-101-what-is-atsc-psip-qam-and-8-vsb/http://hd.engadget.com/2009/05/08/hd-101-what-is-atsc-psip-qam-and-8-vsb/May 8th 2009 2:43PMhttp://hd.engadget.com/2009/05/08/hd-101-what-is-atsc-psip-qam-and-8-vsb/http://hd.engadget.com/2009/05/08/hd-101-what-is-atsc-psip-qam-and-8-vsb/
How is that "piracy"? To do that, he has to have a FiOS ONT terminal in his home, which means he's legitimately paying for service. The only things he can watch are whatever's transported in the clear. There's nothing illegal about that. Please don't perpetuate ridiculous myths like this.]]>May 19th 2009 6:31PMhttp://hd.engadget.com/2009/05/08/hd-101-what-is-atsc-psip-qam-and-8-vsb/http://hd.engadget.com/2009/05/08/hd-101-what-is-atsc-psip-qam-and-8-vsb/May 8th 2009 1:37PMhttp://hd.engadget.com/2009/05/08/hd-101-what-is-atsc-psip-qam-and-8-vsb/http://hd.engadget.com/2009/05/08/hd-101-what-is-atsc-psip-qam-and-8-vsb/May 8th 2009 2:19PMhttp://hd.engadget.com/2009/05/08/hd-101-what-is-atsc-psip-qam-and-8-vsb/http://hd.engadget.com/2009/05/08/hd-101-what-is-atsc-psip-qam-and-8-vsb/May 8th 2009 2:10PMhttp://hd.engadget.com/2009/05/08/hd-101-what-is-atsc-psip-qam-and-8-vsb/http://hd.engadget.com/2009/05/08/hd-101-what-is-atsc-psip-qam-and-8-vsb/May 8th 2009 2:26PMhttp://hd.engadget.com/2009/05/08/hd-101-what-is-atsc-psip-qam-and-8-vsb/http://hd.engadget.com/2009/05/08/hd-101-what-is-atsc-psip-qam-and-8-vsb/
Sadly, it eventually ended and they started encrypting those channels. I ended up switching to FIOS shortly after.]]>May 8th 2009 2:52PMhttp://hd.engadget.com/2009/05/08/hd-101-what-is-atsc-psip-qam-and-8-vsb/http://hd.engadget.com/2009/05/08/hd-101-what-is-atsc-psip-qam-and-8-vsb/ Thanks so much for this rundown. Last week I was just telling Andres (of My Networking Project fame) about how confusing ATSC/NTSC/QAM was. I have a few questions that maybe you or someone else in the forum can answer.
Currently our local TWC offers cable channels over NTSC and QAM. My mother's old CRT TV connected straight with coax gets channels 2-78 (all SD), so those are delivered via NTSC, right?
Now, I have an HDHomeRun connected to my Media Center PC (plus 2 CableCard DCTs). When I scan using the HDHomeRun, I am only getting SD channels 2-24 as well as the channels that would be free OTA (5.1, 5.2, 5.3, etc). Is the HDHomeRun a QAM-only tuner when using the coax inputs? I can't quite understand why the HDHR doesn't get all of the basic cable SD channels from 25-78 like I did with my old PC's internal tuner card.
If TWC is moving everything from NTSC to QAM256 down the road, does that mean that my mother's old TV with the straight connection will not be able to get any channels without a converter box (that has a QAM tuner) when that all-QAM day arrives??]]>May 8th 2009 3:38PMhttp://hd.engadget.com/2009/05/08/hd-101-what-is-atsc-psip-qam-and-8-vsb/http://hd.engadget.com/2009/05/08/hd-101-what-is-atsc-psip-qam-and-8-vsb/The HDHomeRun doesn't support NTSC, so yeah that could be it.

And yes your mom will have to get a STB from TWC when they shut off the analog channels, I'm sure they'll give this out for free.]]>May 8th 2009 3:40PMhttp://hd.engadget.com/2009/05/08/hd-101-what-is-atsc-psip-qam-and-8-vsb/http://hd.engadget.com/2009/05/08/hd-101-what-is-atsc-psip-qam-and-8-vsb/May 8th 2009 5:57PMhttp://hd.engadget.com/2009/05/08/hd-101-what-is-atsc-psip-qam-and-8-vsb/http://hd.engadget.com/2009/05/08/hd-101-what-is-atsc-psip-qam-and-8-vsb/
Correct me if I'm wrong.]]>May 8th 2009 6:09PMhttp://hd.engadget.com/2009/05/08/hd-101-what-is-atsc-psip-qam-and-8-vsb/http://hd.engadget.com/2009/05/08/hd-101-what-is-atsc-psip-qam-and-8-vsb/May 8th 2009 7:19PMhttp://hd.engadget.com/2009/05/08/hd-101-what-is-atsc-psip-qam-and-8-vsb/http://hd.engadget.com/2009/05/08/hd-101-what-is-atsc-psip-qam-and-8-vsb/
Right. So that if you're a PAYING cable subscriber, you can view the local networks through their infrastructure in HD. But if you're not paying for TV from them (and only subscribe to the internet), why should you be allowed the access to the same thing that other customers have to pay for?]]>May 8th 2009 8:26PMhttp://hd.engadget.com/2009/05/08/hd-101-what-is-atsc-psip-qam-and-8-vsb/http://hd.engadget.com/2009/05/08/hd-101-what-is-atsc-psip-qam-and-8-vsb/
From my guess anytime anyone on your node (or some other limiting factor) orders pay-per-view you can see what they are watching at the same time they see it. It goes away when they stop of course, so most of the time those channels are blank. Hotels ppv works in a similar fashion over analog, but the TVs are blocked from tuning those channels (although if you hook up your own tuner you can see them, not that I have ever done that...)]]>May 8th 2009 6:01PMhttp://hd.engadget.com/2009/05/08/hd-101-what-is-atsc-psip-qam-and-8-vsb/http://hd.engadget.com/2009/05/08/hd-101-what-is-atsc-psip-qam-and-8-vsb/May 9th 2009 10:49AMhttp://hd.engadget.com/2009/05/08/hd-101-what-is-atsc-psip-qam-and-8-vsb/http://hd.engadget.com/2009/05/08/hd-101-what-is-atsc-psip-qam-and-8-vsb/May 9th 2009 10:25PMhttp://hd.engadget.com/2009/05/08/hd-101-what-is-atsc-psip-qam-and-8-vsb/http://hd.engadget.com/2009/05/08/hd-101-what-is-atsc-psip-qam-and-8-vsb/
Here in the UK, we'll soon add some new HD services to the Freeview digtial TV service. These will use DVB-T2, and can have a maximum rate of 35.4 Mbit/s. With the addition of MPEG-4 compression, we'll see a bit more HD and SD content delivered over the air than you guys.

That said, we have zero HD in this country really. The BBC does a bit, but not nearly enough, leaving us with US imports and a few ITV/C4 shows in HD.

Three TVs in our house have ATSC tuners, but are only able to tune QAM channels. Without support for manual remapping, trying to find the channel you want, when the carrier is constantly updating frequencies is frustrating to say the least.

So even though according to the "experts" and the government we should be fine since these sets have ATSC, the reality is that it's nearly impossible to watch TV like this.

We have base digital TV service and high speed internet. Is the only solution to get a STB or DTV converter for each TV?]]>Jul 6th 2009 11:39AM
