The purpose of the retune day is to clear UK DTT Mux B which will then be used 
for the rollout of HD on UK terrestrial TV

The modulation standard for the new HD service will be DVB-T2, although iirc 
the final choice on the mode has not been made. The plan is to have around 50% 
coverage in time for the world cup next summer.  All this is going on at the 
same time as the conversion from analogue terrestrial to digital.

Fyi - the
 UK currently has 4 or 5 analogue services + 6 low power T1 SD DTT services all 
running in parallel.

As part of the Digital switch over (DSO) that we are going through, these 11 
services are switched over to 6 high power DTT services, with >98.5% coverage 
for the 3 public service multiplexes and >90% coverage for the 3 commercial 
multiplexes.

These SD high power DTT services are all T1.  The change half way
 through this process is to clear Mux B [also known as PSB3 or BBCB] and then 
use this for HD.

In some areas, the initial rollout of the DTT HD service will occur before he 
switch to high power DTT, so in those areas [eg London] there will be 5 high 
power analogue, 6 low power DTT + the HD service. In these areas, the 12 
services will be merged into the final 6 high power DTT. 5 of which will be 
DVB-T1 SD, and the 6th DVB-T2 HD

I didn't get this HD impact from the
 DTG
 web site's analogous "retune" announcement.

So, HD will be transmitted over DVB-T in the UK now. I wonder what the 
practical effect of this will be on the likelihood of DVB-T2 ever being fielded?

UK: Millions Retune Boxes for HD
09.30.2009.

Viewers in an estimated 18 million homes across the U.K. are retuning their 
Freeview set-top boxes this week in order to upgrade to receive HD programming.

Among other things, the change-over will mean more Brits will get access to ch. 
5 (known as "Five") - while other dwellings may no longer be able to receive 
ITV3 and ITV4, according to Reuters. And some Freeview STBs may no longer work 
at all.

But to hear a Freeview executive tell it, "These significant and necessary 
changes will immediately bring
 Freeview viewers
 new channels, introduce new homes to existing channels and prepare the 
platform for the future availability of Freeview HD."

The technical upgrade to HD was scheduled to take place today (Sept. 30), as 
Freeview officials were asking viewers to retune their boxes starting at around 
lunchtime (apparently no specific changeover time was announced).

The changes, Freeview said, should mean that more than a half-million homes 
will be able to receive Five for the first time.
