How much bandwidth for IPTV?

Good post, as usual , Mr. Evslin.
And, as usual, Patrizia has something to say.
It's amazing how you always touch subjects I am very fond of and my husband is working at.
How much bandwidth is needed?
On the receiving site: Since, as you say, you are supposed to watch at a channel at a time, and since when you watch is most likely that you do not surf, considering the high and good compression available on the market today, you can have a stream of 1 Mbps steady bandwidth. (which is much more than you need for surfing, because it is STEADY) That is what most broadband connections allow now a days.
Providing that NOT all the ISP users are watching TV at the same time, because 1 Mbps of STEADY consuming bandwidth would crash most of the networks, admitting that if it is not possible right now, it will be possible in the near future (and I am talking about big cities, for small town it will still be a dream for long, at least in Europe...)but then : how much bandwidth is needed on the sending site?
And I am talking about real TV, the full screen at a quality close to the TV now.
I mean looking at TV on a decent monitor size, sitting on a couch, a full movie or a TV program for at least one hour or more of STEADY streaming... that is TV and not Youtube or all the similars, short clips of a size of a cell phone screen, sitting in front of your PC monitor.
Of course you agree, you cannot talk about TV in this case.
Well how much bandwidth on the sending side?
So huge nobody right now can afford, at least the TV we are talking about.
And very likely not tomorrow and not the day after tomorrow.
So what?
You have to create something that gives on one side the chance to see full screen at a decent quality, using less than 1Mbps bandwidth and on the sending side THE SAME.

It is not possible, you say. It is possible, and we are working on that and hopefully we will be succesful one day soon.
Believe me THAT is the only possible WAY to have real IPTV
