YouView and multicast
A Digital Spy article (http://www.digitalspy.co.uk/tech/news...) says:
It is understood that YouView is currently developing an IP Multicast solution that could double the amount of free-to-air channels delivered on the platform from 70 to 140, by harnessing internet delivery.Will these channels come only to BT/TT YouView boxes, or also to standalone boxes? Anyone from YouView able to comment? I know this has been asked before. Perhaps it's been answered somewhere?
This has the potential to democratise television by cutting down the high cost of Freeview channel transmission and enabling innovative and new services to reach the YouView audience.
