Oh, did I xpost to u.t.broadCAST? I meant to send to u.t.broadBAND

The way the broadcast industry is going, both groups may as well merge
soon. :-)

uk.tech.digital-tv was a split from uk.tech.broadcast which itself
was orginally split from uk.telecom (and I presume u.t.broadband also
was).
Everything goes in circles. It's just a matter of how big.

That's an incredibly 'brave' statement, in light of the current debate
and research within the broadcast industry !

But hey, I remember saying in 1997 who on earth is going to bother to
use SMS messaging !

Some one well off the mark. B-)

I was using an SMS group based chat system(*) before '97 on Orange. I
think, can't remember what it was called or the exact date. I signed
up with Orange not long after they launched, in '93, though so it
would have been around then.

(*) Started in someones back bedroom with an ordinary handset
connected to a PC. Wasn't long before he had to get a special
unlimited SMS tariff... Early version of twitter in some ways but
populated by people with brains.

I know nothing, but all this data, which when I've watched on-line
appears to time shift after interruptions (or is it buffered in my PC?)
must surely not be going any way but in individual dog-legged lines
through switches, servers, stores and so on.

How much power is it going to take to run all those servers, how much
fibre to pump it down and how does this compare with the cost of
running, say, Winter Hill? How many power stations?

As a doomedDemon customer (Vodaphone, spit) who can't move because of a
constantly retreating date for capacity on the local fttc cabinet, I
just have a bad feeling about all this.

Oh my gard. They will need a whole internet for one footy game, just so you
can see the hairs on the players legs.

It is on a par with IBM's assessment that there would be a world market
for six computers. :-)

You're not the guy I was arguing with a few years ago in one of the
groups when he said that "on demand" TV would never work over the
internet due to insufficient bandwidth are you?

Was at Headingly recently with a copper line feed of Test Match
Special, experimented listening to a few streaming feeds of the same
via the press WiFi. Just for fun I wonder who can get the closest to
how long the delay was?

must surely not be going any way but in individual dog-legged lines

Multicast might be involved with live streaming but doesn't work for
"on demand".

How much power is it going to take to run all those servers, how much
fibre to pump it down

Fibre can support very silly data rates for the backbones, think
Terra bits per second not a mere Gigabit. GPON systems can run at
Gigabit speeds on a single (rather than two, one up one down) FTTP up
to about 10 km. The customer GPON terminal kit is well within the
"consumer" price bracket.

Bear in mind that when BT put in a fibre cable the chances are that
cable will have 96 fibres in it. They sometimes drop to 48 but not
often as the price difference is minimal and the vast majority of the
cost is digging the trenches or installing fibre ducts through
existing ducting.

A Gigabit backhaul from a FTTC is enough for 100 10 Mbps streams. As
an approximation 100 is about the number of customers each FTTC has.
ATM that is ample as most streaming is at a pathetic 3 Mbps. But I
can see it changing within ten years and an average 2.4 kids
household wanting 50 Mbps or more of an evening.
