I see you can get low-res TV's, Hi-Def TV's, and VCR/DVD combos at the
local Big Box Marts with digital receivers built in. In fact, they no
longer sell analog only TV's.

1. Do the digital receivers all function the same way or are there
different features/functions to be aware of? Any receiver brands that
are clearly better than others?

2. Is there any "next big thing" on the horizon that will make them
obsolete and useless or is the current digital broadcast standard
going to be in place until the sun burns out?

3. Assuming many of the VCR/DVD combos are cheap POS units, is it
possible/practical to cannibalize the digital tuner from them?

I think there are some "cable-only" tuners that won't pick up OTA.

When you say "digital receiver", I can't help but think of an audio
component. You mean a "TV set", I assume.

Most sets can display any format (720p, 1080i, 1080p). However, the
less-expensive sets have a native resolution of only 720p, and convert 1080
inputs to 720p.

To avoid obsolescence, your set should be able handle 1080p natively, and be
able to display 24fps directly, without conversion.

Sony seems to have the best LCD sets, Pioneer and Panasonic the best plasma
sets. Look at Consumer Reports, the on-line reviews, and various magazine
reviews. One of the magazines (I forget which) had a detailed study of
whether particular sets properly supported deinterlacing, upconversion, and
so forth.

The Japanese are working on video systems with twice the horizontal and
vertical resolution of the current standards. It will be many years before
they come to market -- if at all. Note the relative "failure" of SACD/DVD-A
and Blu-ray/HD DVD. People are generally happy with what they already have.
It takes time for the public to "digest" technological advances and desire
something better.

The current NTSC standard has been around 60 years and -- used well -- can
still produce excellent image quality. It's likely the current HD standard
will be around at least 20 years, and likely longer.

As for the specific flat-panel technology, there are two display
technologies that might conceivably displace LCD and plasma. Organic
light-emitting diodes (OLEDs) have appeared in a few consumer products
(cameras and cell phones), but don't seem to be making progress in TV. The
surface electron-emission display (SED) was predicted to outperform plasma,
but is currently tied up in patent-licensing squabbles, and appears (at the
moment) never to get to market.

If you buy a high-quality LCD or plasma set, it's unlikely its visible
performance will be greatly exceeded in the near future. If you're really
worried about obsolescence, buy one of the less-expensive Vizios. Though not
of the highest quality, they're good, and cheap enough that you can toss
them in a few years.

excellent reply snipped

William, would you mind telling us which of the cross-posted groups you were
reading when you replied? If not a.t.t.hdtv, perhaps there is another group
for me to subscribe to.

I'd guess sci.electronics.repair since I see him around here regularly.

My understanding of the term is that a "digital receiver" is a
digital TV *tuner*. It doesn't (or at least might not) include a
monitor. It takes a video signal (ATSC, cable, or satellite, or
some combination of them) and converts it into something a TV set
or DVR can accept (S-Video, component video, DVI, HDMI, etc.) It
might be able to downconvert (so an old analog TV set can display
HD signals, although with less resolution) or upconvert.

I would not expect an audio digital receiver to include speakers.
