However, it may now be possible for Sky to also to convert the second commercial multiplex to a subscription high definition service, perhaps with Sky One HD, Sky Sports 1 HD and Sky Movies Premier HD, whilst carrying the ITV2+1 and E4+1 channels using DVB-T2.
It is not clear yet if the existing 80 Freeview transmitters will change modes before switchover, or if viewers will have to wait for the rolling switchover programme.
Once switchover is complete, it is possible that more HD multiplexes will be possible, potentially using "single frequency networks" that could bring another 20 HD TV channels.
This will allow, by 2017, the eventual conversion of all the Freeview transmission to high definition. In ten years, it expected that the entire Freeview service could be transformed to high definition.
1: which services are most likely to drive take up of DTT consumer reception
equipment using new technologies? In particular, are HD services the most likely to do so?
2: do you agree with Ofcoms assessment that it would be beneficial for the DTT
platform to begin to upgrade to new technologies DVB-T2 and MPEG-4 - to make more
efficient use of spectrum and to allow for the introduction of new services?
3: Ofcom is particularly interested in hearing from multiplex operators and
programme providers as to whether they are interested in using DVB-T2 and / or MPEG-4,
and whether Ofcom should consider permitting their use on DTT?
4: do you agree that the earliest possible availability and adoption of the
technologies is in the interests of consumers and citizens?
5: do you agree with Ofcoms view that DVB-T2 MPEG-4 reception equipment
could be commercially available in time for DSO in Granadaregion in late 2009?
Question 6: do you agree that some form of intervention is required in order for the DTT
platform to commence an upgrade to new technologies without delay?
7: Do you have any proposals for launching MPEG-4 services on a DTT multiplex
using DVB-T in advance of the proposed 2009 timetable and if so can you provide details of
how such a service would not undermine the proposed MPEG-4/DVB-T2 launch in 2009?
8: do you agree with Ofcoms proposed approach for adding SD and HD versions
of MPEG-4 and DVB-T2 profiles to the list of permitted standards for DTT in the spring, and
that Ofcoms consent must be sought prior to adoption of these standards?
9: do you agree with Ofcoms proposal that Multiplex B should be cleared and
upgraded to new technologies?
10: do you agree with Ofcoms proposal that all multiplexesshould be required to
upgrade to 64QAM at DSO in order to make the most efficient use of spectrum (ie that the
mode change should not merely be optional)?
11: do you agree with our proposals for accommodating Five, S4C, TG4 and GDS
on Multiplex 2?
12: do you agree with our assessment that nine SD services can operate on
Multiplex 2? If not, do you have an alternative proposal?
13: do you agree with our proposals for the reorganisation process for the existing
multiplex services set out in the central case scenario?
14: do you agree with the principles / conditions that Ofcom proposes to use to
evaluate counterproposals for the reorganisation process?

I hope we will not need another set-top box and tv to recieve service I have not had st-top box long , The Tv companies cannot not expect viewers to pay up everytime Freeview expands and a new set top box is required I mean switchover has only just started, I hope they have thought of this and Iam sure some viewers if nwe box is required will not bother getting HD service
Issue each of the Broadcasters (BBC, ITV, Channel 4, and Five) one HD multiflex each so that a large number of channels can be duplicated into HD. BBC3, BBC4 and ITV4 can be broadcast in 24/7 mode, and Five can make an extra channel.
Dean Ensor: If you want to watch HDTV transmissions, you will need a new box. You will not have any service reduction with an existing box or idTV until around 2012. Your existing box doesn't support MPEG4 or DVB-T2, and it is not possible to upgraded existing chip-sets.

What implications does this have for those of us who have our analogue service turned off before Christmas 2009? Cough up for a digibox this time next year, and then do the same again a year later?
We will get half a service for just over a year, and then loose 5 channels just so that folk who want their telly to dominate their living rooms get a better picture. Its enough to make one a luddite.
The low powerd service has been draged out for 10 years plus, where as in other countrys people were given between 6 and 12 months to go digital. The service has constanly been fidled with causing confusion and miss information.

Briantist: Am I missing something? Most of Borders is served by relays, and I understand these won't get the full service. Are we not now going to get More 4, E4, ITV3, ITV4 and CITV at switch off in 2008, or will we still have More 4, E4, ITV3, ITV4 and CITV once HD starts in 2009?
Sorry if I'm being dull. D
Disserviced: There are a number of possible options. One is that non-public service channels will be moved to the COM multiplexes, the other will reduce the bit-rate (and hence quality) of the SD services, but will keep these channels on the PSB multiplexes. Perhaps a bit of both.
Ofcom I think have lost the plot here, they should get DSO done first and then change over to Mpeg4 and DVB-T2,they are just going to get everyone confused.The BSB's are launching HD channels on Freesat early next year,and those channels will be more or less full time, where as if they launch on freeview in 2009 they will only be on for a few hours,and many people will loose out on SD channels, and ofcoms plan also has to have Sky's Picnic pay service in place as they plan to use there stream in Mpeg4 to put the missing channels in, but Picnic has not been given approval yet,or has it.
@Briantist:Thanks for your excellent technical input on this site. As I'm just in the process of selecting a new LCD TV, the HD Freeview tuner issues have stopped me in my tracks. I like everyone else would prefer to have fully integrated solution, an additional set top box is not for me. I don't see any of the top end TV manufacturers building in any forward compatibility for MPEG4 & DVB-T2 (or do you know of one?). They want to sell us big TV's now (and last year for footie World Cup) and from the timing the next big push will be London 2012 Olympics - Chuck those "old" sets away because you now need a "full" HDTV to cheer on our medal hopefuls. That's market forces
you can find rips of hd/bluray movies at 720p that fit within a 4gb file using h.264, i.e not much higher bitrate than the current mpeg2 broadcasts on freeview. Why don't they stop messing around and just migrate everything to this hidef format, looking maybe tp upgrade to 1080p 5 years down the line if there's a call for it. There's too many half way houses, stop that it's silly.
OFComHD TV and DVB-T2:-The closing date for comments (30/01/08) has now passed. As soon as a decision is reached, I'm sure all those contributors to this page would like to know the outcome. Please .... If anyone has information on what was decided we would ALL like to know what is happening.
Mark: In fact it doesn't work out that way. Progressive is done like a movie camera with a set of static pictures, whereas interlaced is done does top-bottom-top over the period of the frame. For this reason you get a "blur" on a static frame, and this generates more data when MPEG2/4 compression is done to the data.
Geoff.Dixon: The standard has not been approved, the BBC have not agreed to give up lots of bandwidth, it is all 'up in the air' at the moment. The system design is not THAT complicated, 128QAM mode is in use for digital TV transmission in the US (will be the only standard soon), MPEG4 makes sense for any new broadcasts. However, it can ONLY take place at switchover as it will be take the place of multiplex PSB3. Not sure what you mean by 'Regional re-organisation' though. The biggest problem would be the further drop in picturequality for the existing services. No doubt this will be described by the newspapers as some grand conspiracy to make people buy HD boxes if they don't like blurry football matches.
In simple terms, how many SD channels would have to be sacrificed to make way for one HD Channel ??
As we have all seen, multiple channels does not add quality. I guess I have about 45 TV channels broadcast on Freeview and watch maybe 7 regularly and 15 in total. As the 5 terrestial PSB frequencies get switched over to digital, surely the way forward is to have no more than 70 channels, 10 Primary channels BBC, ITV, SKY etc that can broadcast in HD, alongside SD programs, Movie and Sport & Discovery type channels to broadcast in HD then the others need only be Standard. Do I need to watch archive TV programming in spectacular clear resolution, when its a 1980's episode of Minder ??
Also can we not clear the way by taking off QVC and PriceDrop and all these other nonsense channels that serve only to cheapen to value of multi-channel TV
Briantist: DVB-T2 etc.
Thank you for confirmation that this is STILL in 'the melting pot'.
Terminology has never been my strong point - for Re-organisation read 'Regional Consolidation'... or whatever it is really called. I was referring to the amalgamation of the regions. 'Border' to 'Border England' to 'Border Tyne Tees' etc.
Again, thank you for the quick response and an easy to understand reply. I like your "Up in the air" pun.
Geoff. Dixon: The old ITV regions will still exist in some form because their amagamation by ITV1 will be for regional news only, it will not effect the switchover order (Border is early, TTTV is last for example) and ITV1 will have to keep the regions for a while because of the needs of the advertising market. The BBC has no plans to scrap their regions, as they are quite similar to the ITV ones.
Although I AM interested in the "local" Border situation, as I give advice locally to friends, in fact I receive my digital signals from Winter Hill/Lancaster (and because Granada will continue with a 6 multiplex system I intend to stay with Granada). However as I am so near to the Kendal transmitter, from what you say, I should be able to pick up local 'Border' news digitally even after switchover (on the same Group A aerial - as I do now via analogue). I'm still testing 4x Group 'A' aerials, 2x PVR's and 2 digiboxes and having fun as an amateur. Thanks
Geoff. Dixon: It isn't Granada that is sticking with six multiplexes, but the current 80 main transmitters. The commercial multiplex operators did not see fit to apply to extend their networks onto the other 1074 transmitters, due to the costs. As for aerial groups, yes, you can use group A aerials (for Winter Hill) - HOWEVER - after switchover is complete, there MAY be new television services using the old frequencies and it is quite likely that these will be single frequency networks. This means that if you don't have a wideband aerial after switchover you may not be able to get these services. Remember that the grouped aerials were added to the UHF system to deal with analogue interference problems. This issue is now dealt with by the COFDM digital transmission system, for digital grouped aerials bring no benefits and wideband aerials should be used to prevent having to buy one in the future.

Now the standard for Freeview HD has been sorted out, why are there no TV and recorders selling in the UK with integrated HD freeview tuners built in. Manufacturers have been behaving like naughty schoolboys - only just offering enough to get the lowest passmark. I want to see less mickey taking with so called HD ready tv's and real HD ready, i.e. HD freeview tuners built in please. Let's get this digital revolution really started!
All purchasers should hold off buying new products until the manufacturers pull their thumbs out of bums!!!
Mark Barden: The DVB-T2 standard has not been even ratified, there are no chipsets for it for this reason (won't be until early 2009) and the first equipment (tester and early adopter) equipment will be very late 2009, and there will be stuff in the normal shops in late 2009. If everything works out.
are you going to open another film channels that we would like if so would you do it for those of us who like those old films. why can't you open uk TV History all day because this was agod channel when it was open all day when we call them they said that it's up to you to put it back as was before
so could you do so and why can't we have the history channel as well as this thank you
does thie mean that after everyone throws their current gear into landfill and buys new hd stuff that we will have to do the same again when mpeg 5 services launch? Australia is already launching digital freeview tv in mpeg5 format capable equipment...?
And what about DAB+? It is coming soon and will make all existing dab only radios useless...more landfill....
I have a Sony Digital TV which was bought 6 years ago it is a 32inch Serial number 6000675 Model number KD-32DX100U
- I live at Mumbles and am served by the Wenvoe arial. I cannot get any analogue or digital services and Sony have told me to get a Digibox. Surely this isn't right? My system information is:- Version No. r350 (GB)
I think that the whole switchover saga has been badly planned. For instance allot of rouge trader have been informing people that they need to switch-over to a digitalaerial. In fact there is no such thing as an anolouge or digital aerial. The long and short of it is that if you have an aerial receiving a decent signal. Then you should be fine for the switchover. I have also been hearing stories that when the digital transmitter are turned on in France. That it will have a big negative impact on the south of england.
