Well six or seven years later we can look back and see that OTA DTV with 8-VSB did not drive sales of HDTV sets.
That's because from the late 1980s, when advanced TV was being considered, to today, the majority of people went like zombies to pay services. The OTA element is not the significant driver of new TVs. HDTVs are being sold now primarily because they are flat and have bigger screens, are far less bulky, and have nicer, sharper, more contrasty pictures.
You keep missing the point that HDTV is thriving, people are buying them, and it doesn't need to depend on OTA access. Even if the majority are still not seeing true HD sources, they are satisfied initiallly with the improvement provided by the deinterlaced displays. And they are excited by the true HD pictures, especially the sports fans, and want them in their homes. Don't you spend any time in stores?
we have around 7% who still depend on OTA for TV.
More like 30+ percent overall. But what's your point?
Who then is getting their HD fix from OTA?
I am. And people with satellite who want HD network shows. Again, what's your point? They quit OTA long years before any DTT reception difficulties may have arisen.
What if we had talked about doing a multicast DTV
They do that too. WETA-DT has 4 real multicasts. WMPT-DT has 2 real multicasts for now, but plan for 4. A PAX station has 6. Mark Aitken's Fox affiliate has 2 multicasts. The CW affiliates have 2 multicasts. Most other stations have at least a weather channel as a second multicast. I didn't count those as "real."
In any event, what's your point? With cable and DBS, they got their multiple channels anyway. They did not depend on DTT, by 1998, when DTT began broadcasting, to get a zillion channels.
I would bet that OTA would have driven HD far more than it has.
I'll bet you're quite wrong. Most people had already gone lock step into cable and DBS by the time DTV and HDTV sets became affordable. DTT simply came too late to make a difference in DTV or HDTV sales, in the US.
One thing I do know, 8-VSB has DELAYED HDTV sales.
Not even by a microsecond, IMO. If anything, it is cable and DBS that delayed decent ATSC receivers. So I trhink you are 180 degrees out. Had the sale of DTV/multicast-capable receivers and HDTV products depended on ATSC, we would not have had to wait 4 years to barely get to see the very first 5th gen STB on store shelves. Oh wait, I haven't even seen one yet, in the flesh. It will probably be 5 years by the time I see one. (March 2002 was the Linx lab demo.) Anyway, we now have integrated sets everywhere, so even that isn't a problem.
Most people here use pay TV, so no matter what OTA modulation scheme there is, DTV sales don't depend on DTT. Besides, integrated sets are everywhere already, at great prices. If there is any problem left, it is that I can't yet buy a decent DTT recording device. Because people have been suckered into paying the extra rent for the proprietary variety offered by pay services. How obnoxious is that?
I think you need to get off this modulation excuse. It doesn't hold up to logic.
