No, I do not have an HDTV.
I have made inquiries regarding things more associated with DTV than HDTV.
But given the structure of the newsgroups, there is no one group focused
exactly on digital broadcasting. This HDTV group would in theory overlap
into DTV, since for OTA HDTV, DTV is involved. There is a digital video
newsgroup, but that can overlap into other things like Firewire video, and
was not, at the time, very busy.
When I first asked some questions, Jeff Rife jumped to some conclusion
about what I said, and got it wrong. So therefore he thought I should
be looking for one thing, when in fact I was looking for something else.
But before that misunderstanding could be resolved, he switched into
his "personal attack" mode, which basically negated any possibility of
a civil discussion with him. Matthew Martin later jumped in with like
attacks, and a couple other people have taken pot shots. ALL of them
are no longer considered valid resources for information here or in any
other newsgroup, website, or email. I'll never know if information they
might provide in future inquiries is meant to inform or confuse, since
I would never be able to trust their motives.
I do know that in many newsgroups, newbies to that group often get the
third degree. But aside from one anti-spam group, I've never seen it
any worse than here. In that anti-spam group, I'm not the newbie, and
have to sometimes try to get some of the other regulars to settle down.

Actually, I get Pittsburgh better, given the location on the east side of
the hill. So when I do get DTV capability, that should give me channels
25, 42, 43, 48, and 51. But I hope to relocate to a higher location before
that happens, so I can get even more. I do know that channel 7 here has
elected to stay on 7 (giving up channel 32). As for channel 9, there is
choice in first round elections, and they can't stay on channel 57. I do
imagine they might stay on 9, but I would have suspected that would show
up in the first round. The other 2 channels in town are low power and not
on digital, yet.
Getting a digital set depends on what becomes available. I have these
current desires:
1. A portable TV, about 7 inch to 12 inch in size. It must receive digital
so that it is not obsolete in 4 years (since an STB is not practical for
a portable TV). It does NOT need to have HD (not very useful at this
size), but it must be able to handle and display all ATSC formats. This
CAN be in black-and-white. Screen ratio can be either 4:3 or 16:9.
2. A home TV. I do NOT want a big screen TV. But I do want this one to
be HD and 16:9. Using a separate STB for tuning is certainly an option
in this case. This should be CRT technology as I don't think LCD is
going to be very good at this size for HD. I once saw a 16:9 CRT based
computer monitor. I think Sony made it. I guess it didn't make it in
the market, otherwise it might have been adaptable (but probably no HDCP).
The size I want is 16 to 20 inches. I expect at least HDMI or DVI input
with HDCP support. NTSC composite in for SD analog is a big plus, too.
Analog component in is also a plus.
3. A computer tuner. This is more of a special case project. I want one
that provides the raw bit stream or transport stream unchanged (after
RF is downconverted, channel filtered and demodulated, trellis decoded,
and FEC/RS error correction). While Jeff has claimed every tuner will
do this, other people (in computer newsgroups and by email) have said
that relatively few have the capability and are limited most to those
that do the ATSC work in software. I want a corresponding modulator,
too.
4. I'm also looking for a PCI card that includes a DV codec built in and
does baseband video I/O. For input, the software would get DV frames
as blocks of 120000 (for NTSC) bytes. For output, the same format would
be written out to the device. I could use a Canopus ADVC-110 or the like
via Firewire, but I'd rather have a PCI card for this. It needs Linux
capability. It could, in theory, have Firewire on board with video, and
just use the normal Firewire drivers. I have found ONE card that does
this (w/o Firewire emulation) but it is way expensive since it also
does tons of other stuff for broadcast applications: Skymicro Merlin05.
