John: astra 1N is not located at 19.2 but in the Astra 2 cluster at 28.5. See BBC satellite changes: radio, BBC ONE HD, Red button reduction 12-15 October 201 | ukfree.tv - 10 years of independent, free digital TV advice for the details.

KMJ,Derby: the above dates are from the Digital UK master PDF. Looks like I might have to scrape again for new dates...

OK, they have changed the http://www.digitaluk.co.u….pdf file - it's V2 now. I have added in the changes noted.

Peter Henderson: The numbers I am using for LCN were provided to me directly from DMOL.

Peter Henderson: that's not correct. UK freeview SD equipment cannot receive the minimux for lack of dvb-t2 and can't get the roi direct for lack of MPEG 4 decoding.

Tim F: For some reason the auto update on here didn't work for those transmitters. I have manually fixed the database to reflect the correct values.

Richard: In the RoI, the "switchover" is actually just a "switch off" as it is the old VHF transmitters that are being put out of use, and there was sufficient UHF spectrum before switchover for the one active digital multiplex to reach almost all the population of the RoI already.
In NI, however, there were places that cannot receive digital terrestrial TV before, because the four/five UK-wide services took up all the UHF channels, and the VHF services were discontinued back in the 1980s.

Peter Henderson: I think you are getting a few things mixed up.
MPEG4 is used on all RoI Saorview services, not just those in high definition. As MPEG4 provides the same picture "quality" in about half the bandwidth, this makes sense.
The 2k/8k comparison is not the same, as this is a "lower" level.
A DVB-T2 receiver will see the bitstream from DVB-T and not vice versa.
This has nothing at all to do with MPEG2/MPEG4 decoding.
There are some set-top boxes in the UK, those provided by BT Vision, which CAN decode MPEG4.
Saorview boxes, on the other hand, can decode MPEG2 and MPEG4, but can't see the DVB-T2 transmissions.
Also, most MPEG4 receivers can "decode" pictures in higher defintions, and resample them down to SD.

mrdtv: Always happy to correct things!
I also suspect that the coverage will be very robust indeed.
