BBC Northern Ireland funds an opt-out service with the majority of this output made in the independent sector.
Some output that originates in London (so-called 'network' programmes) are time-shifted to create appropriate slots for programming that is more appealing to the BBC audience in NI.
From the late 1990s until 2012, for example, Radio 1 split the home nations on Thursday morning from midnight to 2 a.m., with Scotland, Wales and Northern Ireland broadcasting their own shows to showcase regional talent.
It also provides multi platform interactivity for TV programmes including the annual Schools' Cup Rugby union and Gaelic Athletic Association finals.
[citation needed] BBC Northern Ireland broadcasts almost exclusively in English, but there is some output in Irish and Ulster Scots.
Northern Ireland Screen helps co-fund television output in both Irish[8] and Ulster Scots.
[9] The BBC television and radio stations are broadcast primarily from the Divis (500 kW), Limavady and Brougher Mountain transmitters.
