Northern Ireland "mini multiplex" (NIMM)

I have added information to the UK Free TV database to cover the so-called mini-multiplex that will carry three Irish channels, TG4, RTE1 and RTE2 in a very special multiplex from three transmitters in Northern Ireland.

A special service for 80%-90% of households in Northern Ireland will see three Freeview additional channels being available. These will be:

Northern Ireland RTE1 RTE2 TG4 minimux transmitters

However, you will not be able to view these services using a standard-definition Freeview receiver - a Freeview HD box or set will be required. It is not known at this time if the NIMM will carry RTE2 in HD, as per the Saorview service. TG4 and RTE1 are broadcast in standard definition at the moment.

The requirement for a Freeview HD receiver is because the services are being broadcasting in "D-Book Option 11", which uses the DVB-T2 standard ("a new mode, option 11, is being planned for a multiplex in Northern Ireland. Receivers should be able to switch between these automatically", D-Book 7, DTG164 is defined in appendix G as: FFT size 32k, 16QAM modulation, 1/128 guard interval, PP7, FEC 64800). <img src="data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAABAAAAAQCAMAAAAoLQ9TAAAAQlBMVEUAAAB8fpyEjqz8/vykprx8gqTs7vScnrS8wtSsrsTEytR0epyEiqT09vzMytSkprTU0tx8gpzk5uyMkqy8wsxscpTf9OIKAAAAAXRSTlMAQObYZgAAAIdJREFUGNNdzkFuwkAMBdA3Ywhkiggq978idFHRhCFJFwlI4I3lpy/bKSz1fVl65BXmXQXPWZnKO2jHD9B/wjleS7uBv/t+fjwT0SkxaQs2CGFoG9KayLRTgxtSMJ9fh24i6+qvWmvdMow25ONPD/eTPsnMaX2VCNlXvi7w4BQiDup2JPYFjX+lLiO74pdYSQAAAABJRU5ErkJggg==" class="xico" style="vertical-align:text-bottom" alt="webarchive.nationalarchives.gov.uk link icon"> link iconDigital Television - Technical guidance on the availability of TG4 in Northern Ireland after digital switchover says that Option 11 is: DVB-T2 16QAM FEC 1/2.

Michael: Check the coverage of Divis and Black Mountain on Digital UK's postcode checker. You'll certainly get the PSB channels, and probably the Com multiplexes as well.

It also shows at least marginal reception for the NI mux, so it might be worth putting something up for Divis rather than the Conlig relay.

Failing that, Saorsat would be the best option if you don't want to pay Sky or Virgin:
