The BBC page says the BBC channel is a "UK Wide HD Service", presumably because there will eventally be four "national" versions of BBC One HD, however only one there will only be one version on BBC One in HD (rather than 18 which includes the nations and regions content) across the whole of the UK - so everyone will see the same version, and that stream is currently testing (currently showing the HD channel).
The lack of local variations, at least on satellite begs the question about means that the 6:30pm-7pm slot will have, in place of regional and national news, a holding slide directing views back to their SD channel to view their own local news rather than will it be the return of UK Today?.
The BBC One HD service will also start on Freeview HD, Sky and Virgin Media on the same date.
The HD launch date turns out to be BBC One's 74th birthday.
Update 21/10/2010 14:32 - official BBC press release
The BBC today announces that BBC One HD will launch at 7pm on Wednesday 3 November across all HD platforms: Freesat channel 108, Freeview channel 50, Sky channel 143 and Virgin Media channel 108.
The new high definition (HD) channel kicks off with a series of programmes made in true HD: The One Show, followed by Wallace And Gromit's World Of Invention, the new series from award-winning Aardman Animations, as well as some food for thought with Nigel Slater's Simple Suppers and Jimmy's Food Factory.
The Apprentice and Film 2010 will also show in HD that evening.
It is also announced today that the BBC's award-winning continuing drama EastEnders will broadcast in HD for the first time on Christmas Day, allowing viewers to catch all the drama in Albert Square in even more vivid detail.
EastEnders follows Holby City, which made the move to HD on 18 October. It will be shown on the BBC's existing HD channel, until BBC One HD launches in November.
The new HD channel will simulcast a network version of the BBC One schedule, with the majority of peaktime programmes in HD, including The Apprentice, Strictly Come Dancing, Children In Need, Antiques Roadshow, Countryfile, The Graham Norton Show and The Royal Variety Show.
Jana Bennett, Director BBC Vision, said: "Whether it is seeing the flicker of irritation on Lord Sugar's face in a boardroom showdown or watching the beads of sweat fly from the dancers on Strictly, BBC One HD is the biggest sign yet that HD viewing is now part of the mainstream."
Danielle Nagler, Head of HD and 3D, says: "It's incredibly exciting to begin the official count down to the launch of the new channel and we're delighted to be launching with BBC One's popular flagship programe, The One Show.
"The arrival of the UK's favourite channel in HD â as a second HD channel from the BBC â will increase the range and choice of HD programming we can offer the ever-growing HD audience.
"The existing BBC HD channel has been hugely successful. It will continue to show programmes from across all BBC channels, to allow all HD viewers to find programming they can enjoy. And it will now have space to accommodate more hours of new HD programmes from the BBC."
Bryan Kirkwood, executive producer, EastEnders, says: "Christmas Day in Walford is traditionally turkey, tinsel and turmoil for the residents of Albert Square. This year will be even more spectacular with viewers having the opportunity to watch the festive drama unfold in HD for the first time."
Those shows which aren't made in HD â including EastEnders up until Christmas Day â will still be on BBC One HD but will be upscaled*.
The BBC HD Channel will continue to bring programming such as Top Gear, Wimbledon, children's programming, golf coverage, great drama, comedy, music and factual programmes from BBC Two, BBC Three and BBC Four throughout the week.
We can also announce that this year we'll bring viewers some of the last races of this year's Moto GP in HD as a trial run for the sport on the channel.
The autumn launch is the first stage in delivering BBC One in HD. The majority of programmes in the BBC One network evening schedule will be available in HD at launch and, by 2012, it is expected that the vast majority of all BBC One titles across all hours will be in HD.
In time, the channel will evolve to bring all programmes, news and current affairs to viewers in the nations and regions.
You can follow the progress towards the channel launch on twitter @naglerHD.
BBC HD will be available â from 3 November â on Freesat channel 109, Freeview channel 54, Sky channel 169 and Virgin Media channel 187.
David Taylor: HD transmissions start on the second DSO day, 28 September 2011.
At Oxford, all multiplexes move to their final channels and modes at switchover. However, the commercial multiplexes (SDN, ArqA, ArqB) will be restricted to 12.5 kW until 2012, after March. They will then reach their final power level of 50 kW. We won't know the full details until the London region dates are published on Thursday, and possibly until the rest of the Meridian region dates are published.
There may still need to be a subsequent retune to move the SDN multiplex from C62, unless they sort out the plans before switchover. There were some very late changes at Dallington Park and Luton relays to avoid using C62 (in fact they're using the channel for the next two weeks until DSO2).
