As of October 2012, all analogue TV broadcasts have been shut down, and replaced by Freeview HD (an MPEG-2 DVB-T & MPEG-4 DVB-T2 SD & HDTV service).
Northern Ireland was one of the last UK regions to switch off analogue signals and see the rollout of Freeview SD & HD.
Formerly, only two-thirds of homes in Northern Ireland was able to receive Freeview services from the three main transmitters (Brougher Mountain, Divis and Limavady).
Viewers can receive RTÉ and TG4 via these multichannel networks, as well as, in much of Northern Ireland, overspill from terrestrial transmitters in the Republic.
On 1 February 2010 the Republic of Ireland's Minister for Communications Eamon Ryan signed an agreement with the UK's Ben Bradshaw.
[5] Following a broad range of technical work, the two Governments have now agreed an effective way to provide for the continuing provision of TG4 by building a new, low power TV multiplex in Northern Ireland.
