Well shave my head and use me as a surf board... the BT Vision box
*does* have an HDMI socket! o_O

And, unlike the SCART socket, by using HDMI I don't get those annoying
scrolly watermark patterns on my TV picture. Yay!
I must say, I've been watching digital TV for well over a year now, and
I never really noticed any difference in picture quality other than the
absence of snow and so forth. Other than that, it just looked like a
normal TV picture.
But now I'm watching TV on a big LCD TV, suddenly there seems to be MPEG
artifacts all over the place! o_O
Heh, I guess the old CRT was just too blury for it to show up! ;-)

My projection TV is like that. Less obvious on the HD channels, the
cable system here generally compresses the "less glamorous" channels to
death. It's pretty obvious. The HD channels are usually very sharp and
crisp, only showing MPEG blocking during sections where the picture
changes rapidly.

Maybe.. I'll hold out of the new OLED sets to become mainstream before I
trade in my TV, though, it is a CRT projector, but HD...
I like the idea that OLED has such an incredible viewing angle, superior
contrast ...
what I don't like is that like plasma, it will likely suffer burn-in.

And BTW, what is SCART, and how similar is that to HDMI?

It isn't.
(Or at least, it's a cable that carries picture and sound from place to
place, without RF modulation. There the similarity ends.)

I noticed several adverts with stuff happening underwater had seriously
blocky bubble clouds...
I also watched Ice Age II. Several of the "blue wash" backgrounds were
noticably blocky. (By which I mean there were 8x8 blocks of solid colour
instead of a gradient.) For some reason all codecs known to man destroy
the blue channel...
I hadn't realised that this could very by channel. I assumed there was
just a standard that says "Digital TV = MPEG2 at X Mbit/sec". I'll have
to investigate. Hmm, I wonder what a DVD looks like?
By the way... Watching the snooker, I could actually see the pattern of
the felt on the table (and the depth of field of the camera)!

Essentially that is what DTV is. OTA (Over the air) here in the U.S. has
a set amount of bandwidth. Enough for an HD signal, and several
sub-channels. Most of the local network stations have their main
channel, a weather channel, and a 24hour local news channel.
*Most* DVDs look quite nice. You'll still notice compression in fast
action scenes, though, especially if the encoding was managed poorly.

Wow, looks like some strange modification of a VGA connector.
Convenient, though. So you connect your VCR with one cable, then?

Except it's about 4x the size of a VGA connector, and the pinout is
utterly unrelated.

Indeed.
In the old days, you'd connect the RF arial to the VCR, and another RF
lead from the VCR to the TV, and tune the TV to a special channel when
you want to see the signal from the VCR. (I hope it doesn't clash with
one of your local channels!)
That's because in the old days, a TV would have an RF input, and that's
it. But then people figured out that, actually, RF-modulated signals
look *rubbish*, so various other connections were invented. SCART is the
most popular, since one big connector delivers picture and stereo sound
(though obviously only one video channel, and no telitext).
I have no idea what HDMI delivers. Seems to work nicely though... Only

So, the cable ends are about the size of your average parallel
connector? Yeesh.

Hmm, oddly the U.S. went with the "maze of wires" approach. 3 connectors
out, 3 connectors in. (or 2 if SVideo) or 5 if YPrPb. Though CC is done
in the blanking area, so it doesn't matter how its connected.

HDMI is all digital. Delivers audio and video, As well as signals for
encryption, and the ability for the device to communicate its
capabilities, etc.
