We thought about doing that, but we'll only be in this house for about 
another year, then we're moving again (after the kid graduates college 
and moves out, this house is too big for just two of us); we decided that 
here in Utah, a house with a room that's easily converted to another 
bedroom would be more valuable, so all we have to do is patch the holes 
from the mounts for the screen and the projector - no problem. :-)

If we were going to be here longer, I'd have even run the wires for the 
speakers in the walls. :-)

Got about 16 months of use out of the original one.  Noisy when they 
blow, too - like a firecracker going off.  I'd had one do that to me in a 
class I was teaching once, and still wasn't fully prepared for it when it 
went.

Looks like I can get my bulbs sub-$300, though, which isn't bad; the 
replacement I got was valued at $450 by Mitsubishi.

Yeah, last year our team did a "development week" (for the course 
developers), and one of the recreational activities was a wii connected 
to one of the screens in one of the big classrooms - I don't recall for 
sure, but I *think* those screens are 20' diagonal.

I missed this the first time around, don't know about in MK, but over 
here, ALL of the cinemas are widescreen.

Oh, these were just bolted to planks, basically. Totally movable. Not really 
the actual movie theatre experience, I'll grant.

We did have a row of airplane seats for a while, after the Frnklin Institute 
science museum closed their 747 exhibit and basically threw away the plane. 
Did you know insurance companies value a row of 747 seats at about $700, or 
at least did when we had the house fire back in 1985?

That works even if you sell the house, mind. :-)  I had ethernet put in the 
walls before the put the drywall up, but I definitely should have had the 
speaker wires run too.

> Looks like I can get my bulbs sub-$300, 

I think my brother pays $800 or so for his. They're extra super bright or 
some nonsense. :-)

I think they need to increase the frame rate to 120 Hz or something first 
before making the resolution higher.  24 Hz is ridiculous.

You can't really compare directly.  A lot of printing methods use a 
half-tone pattern to show various shades of colour, an LCD needs only 1 dot 
to show that colour.

It's ok, it's changing.  All HDTV channels are compressed with MPEG-4 (in 
the UK and Germany at least) so I suspect eventually the MPEG-2 compressed 
channels will be gone.

Depends on the ambient light levels whether LCD or CRT offers better 
contrast.  Certainly in office environments (that are usually well it) LCD 
has higher contrast.  In dark rooms CRT is better, but the gap is 
continually closing.

Indeed, it's down to the LC mode used and obviously cost.  Cheap laptop/PC 
monitors are not designed to be viewing from any angle other than 
perpendicular, but a good TV will look the same from all angles (including 
up/down) - it has been that way for many years.

The ones with an HD option look bettER, but still not particularly good. 
At least, the ones I've seen.

Everyone's been filming in widescreen for almost 10 years, at least in Europe
and the US.

  Are there any cinemas in existence that aren't? (Discounting perhaps
some home-made cinemas in some poor countries showing pirated movies from
VHS...)

  You missed the point completely, and misunderstood what I was talking about
really badly.

  The subject was not about "what's better, CRT or LCD?" No, the subject was
about "every time a new technology comes up, it always seems like a huge
step backwards, until it catches up".

  I was simply listing reasons why LCD was a step backwards compared to CRT,
until it catches up.

Perhaps something similar to line perception where we overestimate acute

I use it via a wireless link on my PS3 and I agree that at certain times  
it's quite choppy. Quality is worse than normal broadcast, but it's hardly  
abysmal. For those outside the UK it's comparable to the 4OD channel at  
youtube http://www.youtube.com/user/channel4 where the maximum seems to be  
480p

  10 times smaller than MPEG-2 with the same visual quality? Now that,
I think, would be quite hard.

  Maybe if the MPEG-2 had been created with a crappy software (thus
requiring plenty of bitrate) and then you used really aggressive H.264
encoding settings (something like requiring 24 hours of encoding time
for each hour of video or such), perhaps. But under normal circumstances
10:1 feels a bit excessive.

  Could you take a 1.5-hour 4GB DVD-quality MPEG-2 and make a 400MB H.264
from it with the same resolution and without visible loss of quality?

Again, that's all very nice. But unless you have insane levels of 
bandwidth available, it's not going to work.

There's nothing theoretically difficult about sending video data over 
the Internet. The problem is the bandwidth.

Hmm, interesting. Where I live, most people have between 2 Mbit/sec and 
8 Mbit/sec. (I gather that until ADSL2 is deployed, you can't exceed 8 
Mbit/sec...)

Seriously, I don't have ethernet *everywhere*. I couldn't do surround-sound 
speakers over ethernet. Wireless maybe, but not ethernet.

I told them to put an ethernet wire from the closet to each phone jack. I 
should have said from the closet to each cable TV box as well.

Hmm. Rethinking, 6:1 or so. Basically, you can fit a DVD onto a CD without 
really comprimising the signal.  And remember that when they make DVDs, they 
don't necessarily squeeze it as small as possible. They squeeze it as much 
as necessary to make it fit on the disk, even if they could compress it more.

I misthought. It's more like 6:1. I was confusing Blu->DVD instead of 
DVD->CD or something.

No, it works great over dial-up too. You should try it.

besides game consoles, many people for the past few years have been 
connecting computers to their large screen FullHD TVs.  Because, you 
know, it's usually more pleasing seeing images at a large screen from 
the comfort of your sofa (yeah, with a wireless keyboard) rather than 
sitting a few inches away from a much smaller screen.

BTW, don't you guys find it funny that ADSL is "dial-up" too?  Twas not 
long ago that I used to dial-up at 56Kbps and looked forward to having a 
"cable modem" connection, but today I "dial-up" over the phone line and 
have 10Mbps connections... ^-^

technology advances at a far too ridiculous pace to try to categorize 
with silly terminology... :P

Not really. It's built into the line card, so you're not actually dialing 
anything. You're just using the same wires you would be dialing on.

Indeed, the two hardest parts of making ADSL work is dealing with rings and 
dealing with dialing.

really?  I used to connect without a line filter in my other telephone 
across the room and, thus, if you happened to pick up the nearby phone 
while it was connecting, you would listen to a bit of that "folkloric" 
well-known old-modem dialing-up tune.

Really. I worked across the hall from the guys inventing it.

The signals from ADSL are about 1% the strength of the signals from voice. 
There's no connection there other than you to the line card. That's why you 
can still talk on the phone when you have ADSL.

(Now, without appropriate filters, maybe nowadays you can hear the ADSL. And 
it's doing things vaguely modem-like. But only over the wire. By the time it 
gets to the switch, it's on a separate path already.)

Government regulators, for whom being safe is generally more important 
than being right, had a major role in the determination of the standard. 
  The standard had to allow for broadcast within a strictly-defined 
frequency band, and this limit was chosen based on technology that is 
now ready for deployment to your local museum, because these decisions 
were made years ago.

If I am remembering things correctly, there was even some insistence 
that the signal be displayable by sets designed for the old broadcast 
standard.  If that sounds thinking-impaired, well, that's the FCC for you.

Regards,
John

Which is plenty.

Check out the freeview bitrates:

http://dtt.me.uk/

If the average bitrate of a BBC channel is 3.2 Mbit/s (higher than most 
other channels) using MPEG2, then I'm pretty sure watching the same signal 
compressed with MPEG4 at 2 Mbit/s is going to look virtually identical.

My mother believes she can sing. Even though she's actually about a 
fifth to a third flat. The result sounds truly *horrible*! You'd think 
she could hear the difference, but no...

She also claims to be unable to tell the difference between major and 
minor chords, which is impressive given the vast, world-alering 
difference between the two.

Supposedly 'in-built' but it would be interesting to run those perception  
tests on the same group of people if only to dismiss it as a factor.

How times change. I remember back when I had my house built (Shame I'm 
not in that house anymore, but its all for the better) I requested a 
phone jack near the entertainment center (I did have the living room 
wired for 5.1 surround.

Now with internet-ready consoles and blue-ray players it makes perfect 
sense to have ethernet wired to the entertainment center as well. I 
wanted to wire the house for ethernet, but the builder didn't supply it, 
and wouldn't allow it. But that was no big deal. I think the next house 
I wind up in will likely be an existing home rather than a new build 
since most of the new homes are now too far out of the way for us, so it 
could be interesting to wire some extended services into an existing home.

My dad wired it himself. ;-)

(As in, he literally chiselled out chunks of wall and then plastered it 
over again.)

And then we replaced the Ethernet router with a wireless one. Um... OK.

probably hearing some artifacts from the out-of-band signaling the ADSL 
modem is doing. Which is why you need the filter ;) I remember back when 
I had ADSL forgetting a filter on a phone jack, and picking up that 
phone. It was more like I had a bad connection than anything, though.

Meh, I had a 1Mbit DSL connection for a long time, and my wife could be 
watching Youtube videos of kids playing with cats, and I could watch a 
netflix film at very decent quality w/o interruption for buffering. Of 
course now, with my cable internet bandwidth is no longer an issue... ;)

I think the resolution actually tops out somewhere around 720x480. Their 
STB only supports the SD mode, though it may be progressive scan, or it 
could be that you have a high enough bandwidth connection that you're 
getting less compression.

What I have seen does indeed rival DVD in terms of picture quality, though.

kind of like how NTSC color was kludged on top of the existing black and 
white broadcast signal in the name of backwards compatibility?
