Re: What Mage said.
The US and 7 other region admins are pressing for an allocation at WRC-15, between 618 and 698MHz - that's enough votes to prevent the adoption of a common 'No Change' position, which is what we have in Region 1.
If there were to be a co-primary allocation in even part of the UHF band, and pressure to make that global in the interests of harmonisation, then it would be very damaging for DTT in Region 1, and in particular in Europe where it's a well established distribution method.
I'm not quite sure what's unreasonable about the way things are being done in the EU (I presume you mean Region 1, really, since it's handled at a rather broader level than the EU). Many people do rely on terrestrial broadcasting, which has already given up a huge amount of space to the shysters of the mobile industry. They're after even more, despite not having used up all they've been given so far.
Long term, of course, the LTE gang have desires to supplant technologies like DTT for broadcast, Bluetooth for short range and WiFi as well, all of which have been mentioned in various articles here before. Personally, I don't think that's a brilliant idea (and people in broadcasting really don't think LTE is going to be as efficient as DTT either).
