That could well be an uncompressed feed for UTV. I think ITV circuits - including UTV - have been IP over BT MPLS circuits since 2004 (though the MPLS carriage may have been replaced by a different BT solution since then - as HD was introduced).
Whether TV3 get the same circuit - or just the same contents passed on via a different route and thus a compressed/converted version of it - I guess would be the interesting point. Don't know if BT provide direct connectivity in the Republic, and if not whether it would be carried over a different carrier's network (or a dedicated circuit leased / owned by someone )
When MMDS was introduced, a fibre-optic link was put in place, owned by Irish Multichannel, that provided themselves and Cablelink (and others?) off air feeds from Divis of the NI terrestrial channels. That link remained in place into the 2000s, at least.
Those will be very low bitrate emission-rate SD feeds though, with each service less than 8Mbs (probably around 4-5Mbs). Compare that to the 270Mbs for uncompressed SDI (170Mbs for 8-bit 4:2:2 720x576 if you run 8 not 10 bit and discard blanking), or 1.5Gbs for uncompressed HD-SDI (830Mbs if you accept 8-bit 4:2:2 1920x1080 if you do the same)

Feeds to Irish Channels
When UTV Ireland was in operation, they had access to the same “semi-clean” ITV Network feed that UTV themselves did (and STV still do). On at least one occasion, automation failed and ITV promos were aired on UTV Ireland by mistake. Don’t know what arrangements are in place now for TV3.
