Freesat's BBC One HD/SD swap in Northern Ireland
Viewers with Freesat HD in Northern Ireland will now be able to watch BBC One Northern Ireland HD on channel 101, with the standard definition version moved down to channel 108.
Elsewhere in the UK, BBC One's HD version remains on channel 108.
Theoretically, any of the main channels where there is an HD version covering the same region or nation as the SD version could swap, without being in breach of EPG rules which require TV platform operators to provide the relevant regional versions of the main 5 channels on the first five channel slots.
On Sky, UTV has already swapped its HD and SD channels, and BBC Two HD has swapped with BBC Two SD in England.
