Why? The progs on FreeView HD are pretty well all on SD too. So only those
who want HD and are prepared to pay the extra actually need it.

Think more 'DVB-T2' and less the noddy term 'Freeview HD' which the UK
uniquely uses to describe DVB-T2.

Before the wazzcocks at Ofcom do away completely with DTT, it's a fair
bet that existing muxes will be converted to T2 (coz T2 isn't about HD
per se, but about more 'bits per Hz')

As Peter D points out, there's already a T2 mux in N Ireland, that
carries SD services. So (confusingly) a Freeview HD banded receiver is
required to receive them.

The seeds of confusion are starting to sprout.

Have some more confusion -

The Saorview muxes (mixed SD and HD) from the Irish Republic that are
receivable in Northern Ireland are DVB-T using MPEG4. They need a
"Freeview HD" branded receiver, not SD. The Republic is supposed to be
switching from DVB-T to DVB-T2 in 2013.

How close would you have to sit to a 19" TV to tell HD from SD?

Assuming it is 1920 x 1080 native resolution, then answer is the same
regardless whether the screen is 19, 29, 39, or 199 inches, about 2.5 to
3.5 x picture height.

You omitted:

All the current models that are banjaxed by 4G. (Plus some that will
probably end up going on sale *after* 4G.)

Do you understand what the 4G problem really is?

It will only affect you if you live in certain transmitter areas.

That would ensure reception. However that's not to say a UK DVB-T1
receiver couldn't necessarily receive RoI HD, it may well have an MPEG 4
decoder, which would also be OK for French DTT

switching from DVB-T to DVB-T2 in 2013.


Really ? !

and most who "want" it will be getting it through SKY so a Full HD TV will
be completely wasted on them as well

not so sure about that.

I have the same and it can be a bit of a pain to find a catch up program via
a search box as I have go across the room to type on the keyboard instead of
using the on-screen keyboard that the hummy offers for forward reservations.

No, it will have the potential to affect reception of any UHF channel
between 21 and 60. For instance a masthead amp, that blindly amplifies
anything it receives between 21 and 68 (and in reality an even wider
band than that) under the right conditions could be saturated by a local
4G transmission.

It'll make no odds whether you're watching Ch 21 or 60. The same will
apply to the front end stage of your DTT tuner.

However it'll be easier to deal with in Ch 21-31 areas, because a
filter can be inserted in front of the amp/receiver. Far more difficult
to deal with, if you need to receive something between 55 and 60, a very
sharp cut off filter will be required, which will be tricky (read
expensive).

So, for a 19" 16:9 set, about two feet then.
