Which companies have run the Channel 3 services in the Divis transmitter area
Peter Henderson: We simply don't know yet. Typically the dates are announced with about a year to go. For example, London (4 April 2012) was announced on 7 April 2011, Meridian West (lead transmitter Hannington: 8 Feb 2012) on 15 Feb 2011, and Meridian East (lead Heathfield, 30 May 2012) on 10 May 2011. The later the announcement comes, the later the switchover is likely to be. I think the shortest period between announcement and switchover was for the Channel Islands, about 10 months in advance.
Every region that Ulster TV borders has already switched over, so I don't really see any reason why it can't all happen on the same day. The Sutton Coldfield/Emley Moor switchover next month affects many more relay transmitters and people than all of the Ulster region. Fenton switches on the same dates so that's three 'Full Freeview' transmitters on the same date. The most is five main transmitters with some work to do on the same day - Oxford DSO2, Mendip, Bromsgrove, Lark Stoke and The Wrekin retune and power up all on 28 September, Nottingham and Sheffield have a retune and power up scheduled for the day before.
Some co-ordination may still be required with the Republic, I'm not sure if they've started up Saorview on final channels or not. Because of the pull-out of the commercial provider, they seem to have only launched two multiplexes so far, and one of them just contains placeholder content according to Wikipedia, so they may not have as tight frequency requirements as we do, right now.
Looking at the Geneva 2006 frequency plan, it appears Ireland asked for 4 frequencies at each major site, in addition to their existing analogue frequencies, so the co-ordination may already have been done. (They still use Band III VHF for RTE1 and 2 at many sites, so only six UHF frequencies total are required at those sites, before analogue switch-off.).

I see you've brought forward the approximate date to December next year Brian. Have you heard something ?
John: as far as I'm aware, the mini RTE Mux is in addition to Freevuew. Channel 30 had been mooted for this, but it now seems as if it's going to be used for local TV, which I assume will be NVTV as it's already broadcasting.
I've read that channel 48 may be used for an additional Mux at Divis

Peter Henderson: All the official documentation says the whole UK switchover is complete by the end of 2012, so I have adjusted the projected dates to reflect that.
Don't make any assumptions about who, if anyone, will get the Channel 6 local TV allocation. This is all out for consultation at the moment.
As for the services, the official position is Lords Hansard text for 12 Jan 201112 Jan 2011 (pt 0001) :
"Radio Telefis Eireann (RTE) broadcasts are currently available to some homes in Northern Ireland by virtue of overspill signals from transmitters located in the Republic of Ireland. Consequently, there have been no costs to the UK Government.
As set out in my Written Statement to the House on 20 December, the UK and Irish Government have agreed that the most effective way to provide for the continuing provision of TG4 in Northern Ireland following the digital switchover is to build a new, low-power TV multiplex in Northern Ireland. This multiplex will also carry RTE 1 and RTE 2.
Work on the cost elements of the new multiplex is continuing. The costs of broadcasting RTE 1 and RTE 2 will be met by the relevant Irish authority on a pro rata basis, according to the proportion of the new multiplex used. The other costs will be met by the UK."

If NVTV don't get it Brian, does this mean they'll be forced to close down post DSO ?
I can't imagine Ofcom allowing them to continue on analogue.
