[i.h]

At the moment… the BBC is the only broadcaster to have its own CDN “bidi”
(as well as using the main commercial ones) it does seem to have acted on this  more than most …
unlike the broadcasters who are domestic ISPs …..

UK has the ability for  about the same number people to connect to broadband of greater than 30 Mbit/sec  than get through the air reception ….
But I doubt if the ISPs have enough capacity  everywhere for everyone to be steaming live.

Most issues seem to be inadequate or not rapid enough provisioning, and not  being resilient enough against one CDN having problems,.,..

The BBC also was an early promoter of multicast IP, I remember trying to access their streams back in the day with my new Zen 2Mbit ADSL line.

It remains the perfect solution for live streaming though it requires each ISP to co-operate (but then, so does a CDN since it needs the ISPs to either host servers within their networks or to provide special connectivity).

Closest we seem to have got is the new BT TV Internet mode, but that's only available to BT TV subscribers (and for how much longer)
