Don't be ridiculous. No IPTV system uses VBR like you say it does. Netflix et al give you a solid 15mbit/sec or whatever and that's it.
As far as I'm aware Netflix use both VBR and ABR, so they may encode one 10-second section at 2Mb/s then another at 10Mb/s leaving an average bitrate of 6Mb/s. Smoothing this out is part of what the buffering is for.
3mbit/sec is pushing what is reasonable these days, but you can still watch iplayer and netflix in HD. Yes, if someone else is using the network, itll drop down to SD on netflix. Not the end of the world.
Netflix SuperHD requires 5.8-7Mb. Indeed not, though watching 480p on a nice large smart TV isn't going to be a thrilling experience having just dropped down from SD.
I think it is very telling that one of the leaked BT slides showed that average usage on FTTC was 200kbit/sec averaged out.
It's twice that now, and that includes everyone who may be browsing or even doing nothing on their connection. It's simply taking the number of active sessions and dividing it by the total bandwidth consumption.
It's a total fact that bandwidth usage growth on the internet is slowing down significantly and has been for a while. It's not the late 90s anymore where the demands seem impossible to meet.
It's a total fact that that's not the case. Virgin Media have seen usage increase 10-fold in 7 years and increase by 50% in the past year. The demands are easier to meet because the technology to meet them is more abundant. The technology is there to meet them because the demand for that technology is there.
I was working on broadband networks for most of the early 2000s and the main driver for bandwidth was P2P. It's now streaming which demands high and consistent bandwidth.
LINX hits 2Tb at
consumer peak hours across the public peering, this ignores that to places like Netflix, Akamai, etc, many are going to be using private peering, and still shows a 5-fold increase in traffic in the past 5 years from 400Gb to that 2Tb level. This rate of increase actually accelerated in 2013.
Sky / Virgin Media / Talk Talk / BT Wholesale all reported increased downstream congestion issues over the past year which have required some heavy duty upgrades to address. Ask any of them they'll tell you the same story why - Netflix.
You may also have wanted to look at the presentation some more rather than picking the bits you liked the look of.
Average household data consumption has grown 7 fold in the last 5 years; Ofcom forecast it will grow by a factor of 33 over the next 10 years
I wasn't aware of a huge increase in consumer bandwidth per user in the late 90s. At that time the Internet was still paid for per minute, most of the new usage was academic and business, and broadband was only just in its infancy in the UK.
25% of people use 75% of the bandwidth, it seems in your opinion because you don't require or apparently want that amount of bandwidth no-one does.
Incidentally I didn't raise the whole point about concurrent video usage, the presentation did.
I find your claim that you can't tell the difference day to day between 3Mb/s ADSL, 3G, 4G and fixed line SFBB churlish and absurd. I can and do quite easily.
