Here's a question.

Who goes via who?

I guess the BBC Local Radio Station insert studios go via the nearest regional TV centre, eg Brighton, when used on the NC, goes via Tunbridge Wells, then onto London?

I think things are very different now as they've moved to an IP based network but traditionally, yes that's essentially how it worked

There were contribution lines between the centres for example London-Norwich, London-Southampton, London to Bristol, London to Manchester, and London to Birmingham. Normally there would be 1 in each direction, sometimes 2

So to book a line from, say, Truro to London you'd have to book Truro-> Plymouth -> Bristol -> London.

I remember having problems booking lines to Southampton to London during party conference times because they were all booked for OBs from Bournemouth which were all routed via Southampton


How did Glasgow, Newcastle & Belfast work? All via Manchester like Leeds?


I think they all went through Manchester as well. Might have a circuit drawing somewhere. Belfast and Glasgow certainly went through Manchester.

Bookings from local radio station cameras could be pretty complex and involve phone calls to several newsrooms to book staff to look after the guest, then a phone call to network bookings to actually get the circuits sorted out. You then often had to phone from region to region to actually get the booking routed before you eventually saw the guest. Reverse sound could also go via an equally tortuous route back the other way. I remember chasing one booking from Northampton to Oxford and was asked by an engineer at Television Centre whether Northampton was anywhere near Southampton Rolling Eyes There's a story on the internet involving an early Children in Need where Television Centre were chasing a contribution from Cardiff. CF was always routed through Bristol, but BS had gone to dinner by all accounts ...

There are still plenty of sites that aren't on the IP system; most of them Local Radio stations that have an edit suite and maybe a newsroom camera but not a full TV operation. Brighton has lines to Tunbridge Wells and Southampton which can then be routed on to wherever necessary. Portsmouth and Bournemouth are both microwave links (I think) via Rowridge to Southampton. I think Coventry is linked to the Mailbox via Sutton Coldfield, Worcester might be as well.

Generally speaking, local radio sites and district offices are linked to their associated regional centre but there are a few exceptions where lines go to a neighbouring region then have to be routed on from there - I think Lincoln is part of Hull's region editorially, yet is routed via Nottingham... (someone correct me if I'm wrong on that).

Sub-opt stations at Oxford, Cambridge and Jersey always had complex circuit arrangements to enable them to opt in and out of either the network or their 'home' region. I'm sure noggin will remember the arrangements Cambridge had in their old building - ISTR it involved microwave links via the transmitter. Oxford appeared at first glance to be exceptionally well connected to the network: there was one line from London, two to London and two lines to and two lines from Southampton. However, as the DTT kit all remained in Southampton and there was no true Network feed into Oxford (there still isn't) the four lines to/from Soton were all in use during sub-opts to get on air.

Things have changed with the new IP based arrangements and in many cases are much easier and less fraught. But anomalies still remain and a lot of local knowledge is needed here and there to get it all to work.

Going back to the nationwide clip, it's incredible to think that they not only organised such a huge logistical nightmare of an undertaking on a nightly basis to "Go Nationwide" but that it ever worked at all. I've certainly heard some horrific director stories about working on that show, but in a way I really wish we still had it. Regional contributions to a national show have always been terrific fun to watch in a lunatic, eccentric and thoroughly British way IMO!

Presumably Leeds had to sync to Manchester rather than to Studio E (although Manchester would be in sync with E) but I guess Natlock would have dealt with all that?

The Nottingham contribution studio (when it was an outpost of Midlands Today, before East Midlands Today was launched) was linked with a microwave transmitter similar to that on the OB unit, and linked back via the OB receive facilities at Sutton Coldfield.

I always thought that, but apparently the BBC link from the Bournemouth International Centre was a SHF link from the roof to Nine Barrow Down (the same high ridge that Corfe Castle sits on) and a very long hop from there to Mendip, then on to BBC Bristol. Although post 1995 when Energis look over from BT providing the Beeb's permanent distribution and contribution circuits, Southampton was linked to London in both directions via Bristol, so that's probably why you experienced the shortages during party confs ?

The more obvious route directly into Rowridge, was not used because the link suffered too much from tidal fading.
Although TVS/ITN used a similar path into Chillerton, so it's a bit odd they managed it OK ?

Yep, although because there was so much going through Manchester I'm pretty sure there were direct lines from Manchester - London as well as the option of going via Birmingham, so if one route was booked you had the other option.

Reverse sound could also go via an equally tortuous route back the other way.

We normally used a TBU for reverse sound as it was far easier, and if it was a newsroom camera the last bit of the route was usually a phone line anyway. I remember a colleague of mine spending ages trying to get a line-up from our talkback unit to a remote guest for a pre-recorded interview. of course it never occurred to her just to pick up the telephone and talk down there!

Norwich had some odd arrangements, something to do with steerable microwave dishes, both on the roof and on Sandy Heath to access lines from the various radio stations in their patch. So if you wanted a guest in Chelmsford and someone else was doing a tape feed afterwards from, say, Ipswich they'd have to wait till the dish was turned round. Guildford was another oddity I seem to remember, as it connected like a links truck so wasn't available if news were out doing a non-satellite live in certain parts London!

Maybe, although I remember there being a line each way direct from London to Southampton when I was there in the 2000's.

The issue wasn't clashes with the live coverage, it was more during those times when you had the live conference (presumably going via the route above) and then news having to do lives or send cut packages as well - they would take up the contribution lines, especially as they were block-booked

It's not IP-based: essentially it works as some nice big uncompressed SDI pipes (carried over fibre) which can be booked from one main site to another. The routings are made by CCA in TV Centre.
Smaller sites use a variety of technologies to get into their nearest main site - Brighton still uses an analogue radio link, for example, but some sites in Wales have moved over to IP. (And then there's the joys of the Scottish islands where you might have IP over a microwave link, which adds an extra level of complexity to fault-finding)

Ahh, sounds like a similar system to what I'm used to - a big fibre divided up into SDI 'lines' and data. Do the beeb use the fibre for file transfer too? Are the 'lines' kinda similar in layout to the traditional ones?

For the video side of things, think of it as a big hub-and-spoke network.
For data and file transfer, the fibres are used in a more point-to-point way to deliver the Reith network, telephony, etc.

The details aren't really in the public domain, but sometimes speculation on the internet isn't as inaccurate as you might think.

Yes - there are really two distinct types of vision/sound circuits in use in the BBC these days.

There are the RAMAN circuits that link the main BBC English Regions, Nations and London production centre buildings (including the Oxford and Cambridge - but I don't think Jersey - sub regions). These are now all independent circuits to and from two hubs (so there is redundancy). This has also meant an end to routing via multiple BBC centres (no Glasgow->Manchester->Birmingham->London you can now just route Glasgow->London) These circuits are either 270Mbs uncompressed SD, much higher bitrate uncompressed HD (I think) - though Dirac Pro kit can be used to carry compressed HD over a 270Mbs uncompressed SD circuit (particularly useful in older buildings which don't have much HD infrastructure)

However, there are still legacy circuits (and replacements for them) that link smaller sites to the nearest BBC regional centre, and link microwave receive points to nearer BBC buildings. These can be analogue or digital microwave, fibre etc.

So there may be a feed from a local radio station (say BBC Luton) to a microwave receiver at a transmitter, then a legacy fibre feed to the nearest BBC regional centre (say BBC Cambridge) from where the circuit can be patched into the main BBC contribution network. Many of these legacy circuits may still be PAL composite analogue (or in some cases digital) - or they may use newer compressed component video over IP technology.

(Prior to RAMAN the BBC had 140Mbs PAL composite digital circuits between sites - the same system also used for "analogue" network distribution to BBC regional centres - but some were converted to carry 4x34Mbs compressed component circuits to increase capacity ISTR?)

I've had this file for a few years, which seems to show a gallery monitoring the local news/opt-outs from the BBC English regions. Can anyone explain what and where it is? The picture is a few years old at least.

On that picture, any idea why Norwich is showing East Midlands Today yet Cambridge are showing Look East?

BBC Broadcast Support, Birmingham.

They monitor and support all BBC English Regions, they have been shown a few times on Points of View and Midlands Today (mostly concerning DSO). It used to be based in Pebble Mill, here's a pic of it there;
