david: See Local television on Freeview | ukfree.tv - 10 years of independent, free digital TV advice
Salisbury is "phase two" for Local TV.
There is a plan to extend local DAB to Salisbury - http://stakeholders.ofcom….pdf - but no timing at the moment.

Dave Lindsay: Thanks for that...
As for (1) I have removed these from the main maps now (for the reasons you specified) but they are retained on the C21 (474.0MHz) before switchover | ukfree.tv - 10 years of independent, free digital TV advice Freeview/Maps/Frequencies page for reference.
As for (2) the "first round" is the 60/61 clearance - refer Freeview news | ukfree.tv - 10 years of independent, free digital TV advice and Freeview news | ukfree.tv - 10 years of independent, free digital TV advice and the big list - 4G mobile | ukfree.tv - 10 years of independent, free digital TV advice .
These are mainly changes that shuffle C61/C62 to C39/C40. I was planning on re-generating the maps when each changed occurred, but it might be sensible (as we know where everything will end up) to generate maps for the final version. Let me see what I can do - it takes a lot of computing time to generate the maps (even when I use an 8-CPU AWS large-memory instance).
The next phase will be the 700MHz band clearance, which will create a LOT more issues - but we don't have a full plan for that one yet, as it will reduce the number of frequencies quite a lot.
I'm just going to write about 4G superhet overloading first...

John Baker: It is somewhat in the nature of a fault such as this (unlike planned engineering works) that it won't be fixed until whatever it is that has gone wrong is sorted out.
The oldest TV advice is the best here: do not adjust your set!

r.coupe: This is what you would normally expect, and the documentation for DAB reception often mentions this.
There are several reasons for this, and these range from reception at ground-level often being indoors, whilst high up the reception could be outdoors.
The VHF-band signals propagate though the air well, but if the signals bounce off objects (buildings for example) they become weaker.
The basic "line of sight" for a radio (frequency) receiver is a function of the height of the transmitter AND the receiver's aerial. And whilst L-o-S isn't required for VHF signals, as they propagate "over the horizon", the L-o-S provides a guide to where reception is possible.
Also, remember that digital transmissions tend to result in all-or-nothing. You have perfect reception of the digital bitsteam, or you have nothing at all. This is called the "digital cliff".

brian: I copied all the FoI request information here - Freeview news | ukfree.tv - 10 years of independent, free digital TV advice ...
disclosure of the antenna radiation patterns into the public domain could lead to these being available to foreign administrations, which would substantially weaken HM Government's negotiating position with respect to international frequency clearance;
a weaker negotiating position for HM Government may lead to additional cost for the broadcasters (where antenna systems have to be re-built as a result of international coordination) and lower coverage for viewers (where antenna systems have to be restricted in order to protect foreign transmissions); and
the BBC is required to provide coverage of its services on digital terrestrial television to a certain proportion of the population by the completion of switchover and a failure or suboptimal result from international co-ordination may harm the BBC's ability to meet this obligation.
Costs were not an issue. The BBC had the full data and redacted it when sending it to me.

David: No. In England and Wales, BBC One HD will continue to be the London-without-regional-news version that has been broadcast up to now.
101 on Freesat will continue to be BBC One in SD, as will channel 1 on Freeview.
| link to this comment |
ian from notts: Two reasons. Firsty, there isn't any more space - see http://www.onlineconversi….pdf - the above diagram only shows radio, TV and mobile phone for clarity.
Secondly, the former TV signals frequencies are a sweet-spot. As lower frequencies penetrate into buildings better, and carry longer distances outside; and higher frequencies carry more data, the 800MHz band give both.
Note how 4G mobile phones work less well inside, and how 3G "900" GSM phones need less masts for their netowork than 3G "1800" GSM phones.

Declan McGrath: Llandonna uses 40/43/46/53/57/60 so if you read the article then WHEN the action takes places IF the winning company puts a mast between you and the transmitter AND you have a filter OR you have poor cables AND the polarities match then MIGHT be effected.

Provision of Freesat or free Virgin Media services for affected homes
This leaves providing a replacement Freesat installation (including multiple sets and Freesat+ boxes) for the 30,000 homes with their Freeview reception disabled, or the funding of a basic Virgin Media package. The total cost for this is ten million pounds.

Roy in Eastbourne: I remember we had a black-and-white TV set that supported both 405 and 625 lines.
I do recall turning the "on switch" the wrong way and it broke off in my hands.. and you could see mysterious wires if you looked though the hole.

Wayne: There is an allocation, as I said, on ASTRA 1N, transponder 61 (11023MHz Horizontal DVB-S2 23000-2/3 8PSK) for BBC One Wales.
Officially it's "soon". As Wales is an entire region for both ITV and the BBC (unlike Scotland where Scotland has five sub-regions) the transmitter technicalities are simpler.
I would expect that the BBC are probably waiting for the BBC Wales newsroom systems to be updated to HD. As I recall, BBC Scotland was upgraded to HD-capable some time ago.

Steve: The Waymouth transmitter didn't carry any IBA service on 405-lines, only BBC1 South: C1 at 0.05kW H
Black and white days, VHF bands I and III television | ukfree.tv - 10 years of independent, free digital TV advice has full details.
ITV in this area came from Chillerton Down (Isle Of Wight, England) with Southern Television: C11 at 100kW V or Stockland Hill Westward Television: C9 at 100kW V
| link to this comment |
The BBC, with it's "universal service obligation" had more 405-line relays than the IBA, which was more about profit than public service, at least when it came to coverage.
So the BBC had relays like Weymouth to fill in coverage.
It is worth noting today that Freesat and Sky users registering a Waymouth postcode will get both ITV West Country and ITV Meridian (South Coast) options due to the historic overlap.

Also .. it does say "Weymouth was not an original Channel 3 VHF 405-line mast: the historical information shown is the details of the company responsible for the transmitter when it began transmitting Channel 3."

ian from notts: I tried to make this all clear in the How do I know if the 4G broadband will overload my Freeview? | 4G mobile | ukfree.tv - 10 years of independent, free digital TV advice article, there are two ways you can be effected.
1. "direct" interference - which is a mast transmitting on a signal on a frequency near to one you want for Freeview; and
2. "indirect" interference - which is an overload condition and happens regardless of the frequency you are going for.
The masts will all be using C61 to C64 for downlinks, the phones will be using C66-C69 for uplinks. C65 will be held clear.
The six winning operators will get 5MHz each.
Until we know who wins which 5MHz, and then where and when they deploy their base stations, will we know better who might be effected.
However, until then, the above maps is the best guide as to the "general areas" where there might be issues.

Stuart Owens: Just to add to the above, the issue is also that digital TV receivers with superheterodyne circuits suffer from the N+9 problem - there is a distinct interfere problem nine 8MHz channels away - so C52, C53, C54 and C55 are *MORE* likely to have problems.

However, there is a press release saying Film4 HD will be coming to Sky ... Sky customers to enjoy comprehensive access to the best of Channel 4 - Channel 4 - Info - Press
However, there are no listings for Film 4 HD on satellite I can find...
| link to this comment |
Brian Wright: It is certainly interesting that Sky have been allowed to grab HD versions of channels on an "exclusive" basis, using their enormous marketing budget to gain exclusive deals.
It is certainly strange that channels from public service broadcasters (ITV2, ITV3, ITV4 etc) are not free-to-air on satellite when their SD versions are!
I suspect that Ofcom (or the Competition Commission) took the view that "HD" was too small a market for them to worry about.
Now that we might see the need to move to DVB-T2/MPEG-4 in 2019 to clear the 700MHz band for broadband, it is possible that "Sky HD exclusive" deals will happen less...
You have to realise that HD is good for Sky, in that it creates a "premium" product (like Tesco Finest) for their top-level customers (Freesat from Sky being Tesco Basics).
HD is just a technology upgrade, which needs a little more bandwidth (but less than three analogue channels) and some additional production values.
The way Sky HD is sold, it is a "differentiator product" for customers who wish to have something better than the plebs, so they can show their wealth off by making big profits for Sky.
It's not like Sky are the only company to do this...
| link to this comment |
Rog : In the 1950s there was such limited bandwidth, that there was very little ability for competition.
Today, there are huge numbers of websites, newspapers (free and paid for), commercial radio stations that it is very hard for a media company to dominate.
Ofcom has done quite a lot of work on measuring media plurality for the Leveson Enquiry.
You can read their report here - http://stakeholders.ofcom….pdf .
So, to answer your point, the "firm ruling" has not been forgotten, but the media landscape has change and the laws have changed to match.
| link to this comment |
... the intro mentions:
Plurality matters because it makes an important contribution to a well-functioning
democratic society through informed citizens and preventing too much influence
over the political process.
We have defined plurality as a) ensuring there is a diversity of viewpoints
available and consumed across and within media enterprises and b) preventing
any one media owner or voice having too much influence over public opinion and
the political agenda.
Plurality needs to be considered both within organisations (i.e. internal plurality)
and between organisations (i.e. external plurality).

It's a guess, but if BT are paying "£246m a season" [1] for their football, they probably will be happy to fork out the money to get it on all the UK transmitters in HD.
The ONE THING you can be sure of is that BT won't be wanting to do that Sky-exclusive HD deal...

David: In addition to what Dave Lindsay has posted, ITV is required to conform to certain rules when it comes to advertising, because of their market domination. It's called Contract Rights Renewal (CRR) - see CRR explained: how contract rights renewal binds ITV ad sales | Media | guardian.co.uk .
ITV has to show non-national adverts, as part of this legal remedy.
The only regional content in England the BBC has is the regional news slots, and none of the studios are equipped for HD. For this reasons the BBC isn't spending money on HD versions for the English regions where it will only deliver SD content.

David: Your assumption is incorrect.
ITV HD has London on 10832 H, Meridian and Central West on 10936 V [also STV], Granada on 10994 H

Tony Hill: If the "Freeview HD" extension proposals go ahead, the BBC have said they might then put HD versions of the "UK wide" services on it, and presumably Freesat as well.
Given that it would require just TWO transponder slots for BBC three/CBBC and BBC FOUR/CBeebies, this seems reasonable.
BBC One HD has four slots (England, Wales, Scotland, NI) and BBC TWO HD will have one.
Also, the BBC News channel is moving to a HD studio in NBH within weeks.... it would be a great shame for all that HD investment to not result in BBC News HD in the UK.

Nedbod: Given the prominent Freeview, Sky (and Virgin Media and Freesat) placement for the channel, and the cross-subsidy from having cash from the extra channels on the multiplex it is quite likely that the local TV channels will work.
The difference from the BBC and ITV services is that they are for Manchester only, not all of Granadaland. Liverpool, Machester and Preston will have their own TV.
ITV and the BBC has to cover as far afield as the Isle of Mann.

Nicholas Willmott: Just to nip in here and the question about relay picking up the off-air signals.
As there are a small number of such sites - plus another 55-ish that are used for "cable head-ends" are know and will be dealt with specially.
MW can't be used for LTE, it would not be able to provide any useful bitrate.
| link to this comment |
jb38: From what I have seen from the public statements by at800, it would appear that the proximity to a mobile phone mast (1.5km) is the primary effect on "overload" interference.
The second effect is that masthead and domestic (ie, unshielded) distribution amplifiers are problematic.
Another point, which was in the first lot of the Ofcom reports is that Virgin Media Boxes CAN be effected.
| link to this comment |
Nicholas Willmott: It's a very small number compared to the millions of homes in the UK with off-air reception. And they are all owned by one company (Arqiva).

Nicholas Willmott: It's 5MHz per operator per direction (one up, one down), with O2 having two and Vodafone having two allocations, with 3 and T-Mobile having one each.
The problem with FM radio is there would be no room for the 10MHz of "duplexing gap" between the upload and download allocations.

Nicholas Willmott: Normal mobile phone internal aerials are used for LTE. That is all that is required.

Kurt Eaves: From all the pre-testing that has been done, you should just need to put a filter in your system between the TV aerial and the IRS system.

Kurt Eaves: I'm not too sure what "alot of noise" could be as 791-821MHz are cleared for 4G mast-to-device, 821-831MHz is cleared for the guardband, and 832-861MHz is cleared for use as LTE device-to-mast.
It isn't very likley that the FM or DAB aerial will pick up 4G signals, but poor cables from the aerial to the triplexer could be an issue.
Can you describe the "Freeview problems"? Which multiplexes are effected? How do the problems manifest themselves?
Also, did you get the At800 mailer?

Mike Dimmick: Very good points.
I will have to have a look at the presentation on BBC TWO HD today, but a counter-argument is that they might maintain an SD sustaining feed for BBC TWO as there is no need for the Scotland, NI and Wales versions to have an HD sustaining feed. This contrasts with BBC One where there are HD versions for Scotland, Wales and NI.
I'm not sure about the BBC using the capacity currently used for "303" on Freeview HD multiplex (BBCB) as they have offered to sell it off - BBC advertise for a new Freeview HD channel | High definition | ukfree.tv - 10 years of independent, free digital TV advice - but my *GUESS* is that BT will pay for this for BT Sports 1 HD.
I doubt very much if the BBC will want to alienate BBC ONE HD 2D users for the special Doctor Who with a MHEG-made low-res version. Especially if it won't work with a PVR.

From Alix Pryde on BBC - Blogs - About the BBC - Hello BBC Two HD; Goodbye BBC HD :
". I've confirmed with my iPlayer colleagues that the position is as follows. By the end of this year we hope that all programmes produced in HD will be available in HD on iPlayer, regardless of whether they have been broadcast on an HD channel. In the meantime, HD content on iPlayer has to have been broadcast on an HD channel, or else have been selected to be put through a separate process. Theres a limit to the number of hours of programming per week that can go through that process, but over the coming months we will be selecting those programmes carefully to try to minimise disappointment.
Then there was the topic ... about the potential to offer repeats of BBC Three and BBC Four series on BBC Two late night or overnight. Its an interesting idea and I have passed it on to Janice Hadlow, the Controller of BBC Two.
highlighted some picture degradation on BBC One HD in the North of England. About the same time, we also received notification of the issue thanks to people contacting the Reception Advice service. Im pleased to report that once we became aware of the issue, my team worked with our supplier to get it fixed quickly by swapping out a single faulty encoder, which took place early on Wednesday. Its clear though that the issue shouldn't have gone on for as long as it did and Im looking into that.
in response to a query on Andys blog, I can confirm that we are updating the references on BBC websites to the EPG numbers for our channels."

"The much anticipated local DAB digital radio transmitters for the Wrexham, Chester and Liverpool areas have been switched on this morning in Wales.
The new multiplexes were officially launched at an event at Wrexham Football Ground with local politicians Ian Lucas MP and Lesley Griffiths AM helping to press the button.
The switch-on means that 2.2 million people in North East Wales, West Cheshire and Liverpool can now listen to BBC Radio Wales, BBC Radio Cymru, Real Radio Wales, Nation Radio, Juice FM and Dee on DAB on DAB digital radio for the first time."

ian from notts: "In some properties, an amplifier or TV signal booster is connected to the aerial to distribute a TV signal to multiple television sets. These are often fitted directly to the antenna on the roof known as a masthead amplifier or in the loft. The at800 filter that prevents 4G signals reaching TV tuners should always be connected between the antenna and the amplifier in these systems. If you are a private tenant, you may need to ask your landlord for permission for an aerial installer to have access to these areas of the building."
Installation support for households | at800

..."If you have a masthead amplifier attached to the antenna on your roof, a weatherproof at800 filter will need to be installed. We will arrange for a professional aerial installer to do this for you. You will need to call our contact centre to book an installer appointment. We will want to know what interference problems you are having, and get more details about your amplifier. There may be another solution to the problem that doesnt involve sending out an aerial installer."

However, as we don't know yet for sure where the Freeview capacity for the BT Sports channels is, it is possible that BT has obtained the capacity on the Freeview HD multiplex, PSB3/BBCB.
If this is the case, it won't be compatible with existing TUTV equipment.
