There is mounting uncertainty over the commitments of millionaire John Griffin
The Irish Diaspora-focused broadcaster Irish TV is said to be in talks to secure new funding.
The network, which bills itself as Ireland's first international TV channel, has been viewed in over 140 countries across the world.
But the Sunday Business Post reports the channel is scrambling to secure new funding amid mounting uncertainty over its main backer, millionaire John Griffin.
It is thought Mr Griffin's involvement with the station may be coming to an end.
Headquartered in Mayo, Irish TV also has offices in Ulster, Leinster, Munster, Manchester and London.
The channel's flagship 'County Matters' series comprises weekly half hour shows of news and views from each of the 32 counties - while stories around the Irish communities in the UK and USA are also broadcast regularly.
It is available on the Sky and Freesat platforms, and is due to be rolled out on Saorview later this year.
The channel says it is also planning to launch in the US via Virgin Media and Canada via Verizon.
However, the Sunday Business Post say this appears to have not occurred yet.
