simon14: Then those out of fibre coverage can go off DVB-T,
Unfortunately the set of people that won't get fibre significantly overlaps with the set of people that can't get DVB-T, and it is deemed not economically viable to extend the reach of fibre or DVB-T. Therefore your suggestion probably wouldn't be a good solution.
From what you've said it sounds like you have some insight into the UFB decision making process. Do you know if/why an open IPTV simulcast of Freeview wasn't included in the UFB plan?
