Shows that people forget or get lost in time

Riaz posted:
Equinox. A science programme on C4. Was it an American production?

Not specifically US. It was Channel Four's (launch?) science strand. Like the BBC's Horizon, it may have included US co-produced documentaries (and may have acquired some US docs as well)

Quote:

Q.E.D. A science programme on BBC1 that was more populist and light-hearted than Horizon shown on BBC2, before Horizon itself became populist.


Yep - QED was very different to Horizon. It had a massively wide remit - and was less 'pure science' than Horizon was.

If you want another 80s science strand, then 'Antenna' which was on on BBC Two, and was a science magazine show (not studio based - but linked by stings and graphics) that I remember was very effective. It filled a gap between the populist QED, allowed longer items than Tomorrow's World, but that wouldn't have sustained a full Horizon.

Other science shows I remember from that era - "Bodymatters" (which concentrated on health, medicine and human biology science at peak time on BBC One!) and "Take Nobody's Word For It" (which may have been an Open University co-pro and ran on Sunday mornings I think)

South West England & CI Thread

Why is it that Look East from Cambridge smoothly manages to opt back to Norwich during the 6:30 perfectly every time, yet BBC Oxford and CI both often have long pauses and holds on the sting they play out, as if they can't time it properly? Sometimes I've seen fifteen seconds of hold from Oxford, but Cambridge ALWAYS seems to have exactly enough content to take them up to the point they hand back. Norwich plays a sting ahead of a 'coming up' sequence when they opt back which I imagine makes things slightly smoother, but the presenter is never left dragging the final link out.


It relies on the main opt's gallery keeping the sub-opts gallery director up to date with timings on the main programme as it's going on, which in a lot of cases they don't. Most of the time the timings match what is on the running order, but if the main opt has a couple of lives, they're far too busy trying to keep their own programme to time, never mind trying to keep a sub-opt in the loop. Some directors are actually very good at trying, and some just don't bother. So really what ends up happening is the sub-opt director (in Jersey's case anyway) is literally just watching the main opt go out, and trying to find an ok part to crash back into after the sting.


So I think the answer is that Norwich are probably more disciplined than Southampton and Plymouth then...

When the Cambridge opt started at Look East, both sides treated the opt-out (which was later in the show, with the start pan-regional) as a branded 'Close Up' more-local news belt, with the opt-back usually on the still-to-come element. This meant both sides created fixed duration news-belt sub-opt running orders. I suspect if you start the show split, and join at a fixed time, that discipline is trickier, as the two halves are not doing 'the same thing'

That said - Norwich and Cambridge switched to the 'split opening' format a while back - maybe they just still remember the importance of it.

I wonder if Plymouth/Jersey and Southampton/Oxford have 4-wires between their respective galleries. Look East certainly used to (well it was a PTB feed and a 'control circuit' (RIP) )

Shows that people forget or get lost in time

Any remember Spatz?

https://www.youtube.com/watch?v=2t_BxiX-5JU

Or it's successor Cone Zone? Both were by the same writers.

Yes - remember Spatz. Wasn't it an oddball UK/Canada co-pro - with some nasty conversion artefacts on some/all of it?

Al Jazeera to close?

Also people who posted here about BBC Arabic being "closed". Well fear not. You can live stream it on Youtube you know. Wink

A previous, Saudi-funded, BBC Arabic Television service existed between 1994 and 1996, but was abruptly shut down for being more editorially independent than its backers would have liked. There's a bit of a history (from 1997) here: http://www.preddonlee.com/arabic.html


Yep - and the exodus of well-trained, BBC-experienced, Arabic speaking presenters, reporters, producers and production crew were rather useful to Al Jazeera when they launched their Arabic language channel...

Helicopters Used for News Coverage


You would probably feel much more at home with public radio in the US, which has a strong tradition. I know next to nothing about radio in the UK, but US local public radio feels somewhat similar to regional TV news in the UK. Local public radio news stations have much more humble operations than US local TV news stations, and it's all much more driven by NPR's nationally-distributed programs which have allotted time for local inserts each hour. In late morning and early-to-mid evening slots, NPR affiliates in large cities often have 30-60 minute local newscasts that follow the national programs, but not always. Staffing typically consists of one or two anchors and a handful of reporters covering more meat and potatoes issues than what you'd see on local TV.

Compared to the UK, public television in the US never developed a strong tradition of local news coverage, let alone very much national significance. PBS was starved of resources for decades, leading us to the current situation with commercial broadcasters leading in pretty much every area (entertainment, national news, local news, etc.) At least our public radio is pretty healthy.


Yep - I listen to NPR occasionally. ISTR that the BBC World Service and WGBH Boston have a joint radio production with a US public service radio operation (PRI) called 'The World'

Wimbledon 2017

How does the main studio at Wimbledon operate? For years now it has looked very nice in BBC Sport London 2012 style (and indeed I think it was the only sport to get a London 2012-esque set, a shame it didn't become the house style for a while), yet this year it has a new look.

Today at Wimbledon came from a different, open air studio using the same style desk as seen in Rio and I think also at Euro 2016, but the main indoor studio sports a completely different look - is this a set bought in by Wimbledon itself? If so, why have the BBC been able to have their own design instead for the last however many years?


The BBC put whatever set they want into the main BBC Wimbledon studio, they wouldn't have a studio design imposed on them. I think historically Wimbledon has ploughed its own furrow a bit in design terms.

Even with the changes to the way Wimbledon will be produced next year (when the BBC will - I believe - no longer be host broadcaster and won't be producing court coverage) the domestic BBC presentation studio will still be entirely decided by the BBC in set terms.

50 years of Test Card F

The stuff I digitised from my VHS/Video 8 collections ended up like that too, I presume it must have been how the capture card/software works. As I said though you don't even notice it 99% of the time. And I'm not going back and re-digitising it all either, it took me months.


How did you digitise it? Was the capture card also doing a hardware MPEG2 or H264 compression process, or was it captured uncompressed with a software compression ? I assume it was kept 576i?

Wimbledon 2017

First time I've seen Red Button+ advertised in quite some time - it's always been "BBC Sport Website" lately despite the connected service being rolled out significantly in recent years.


Why do the BBC never mention the BBC Sport app available on smart TV's? All courts in HD, unlike the awful red button streams that they always push.


On my TV the Sport App streams are still unwatchable 25p - I'd rather watch sport in 576/50i than 720/25p...

And Red Button+ is Connected Red Button - which uses the same streams as the Sport App doesn't it?

50 years of Test Card F

I think the answer lies in your last sentence. From memory, in the days of CRTs driven by colour difference signals, you could turn down the brightness of the telly (it might have been contrast) and on the screen you were effectively left with the displayed chroma signal. It really showed up the lack of pretty much any definition in the colour signals which is no surprise really. Quite an 'other worldly, ghostly effect'.


You can do that with digital video too (I've done it in VLC) and the effects are pretty much the same. In fact on quite a few things I notice the chroma only signal sometimes isn't properly interlaced (so it looks filmised or whatever), but added to the 50i luma image you can't tell it apart from sometimes if there's some very saturated colours and fast movement together (I've noticed this a bit on some news reports over the last few years). It does show, how bizzarely little colour information there actually is in a picture.


Yep - there is definitely a 'chroma bug' knocking around in some processing. I've seen video where the chroma has been treated as 25p, but the luminance as 50i - so saturated red and blue content looks juddery, but less saturated stuff looks nice and fluid...

Some ffmpeg processing used to do with 4:2:2 1080/50i sources deinterlaced to 1080/50p.

50 years of Test Card F


To throw a wobbler in! We had a fancy zone plate generator to push variable 'concentric circles' through some of the analogue kit and look at the results. Not sure it really told us anything really, we'd switch filters in and out, push it through a DVE etc. I think the engineering department had a bit of cash left over one year so we bought one, more of a lab tool I suspect than a day to day production engineering need!


It would have shown how horrible a lot of DVE processing was back in the day... Lots of aliasing...

I've played with one - you don't want to push it into domestic displays with non-1920x1080 panels (or those that have not have overscan disabled), and it shows the limitations of certain compression codecs quite effectively as well (particularly those that subsample)

Isn't it the same with half the vertical colour resolution with digital when we're using 4:2:0 colour subsampling, or am I getting that wrong?


Yes - 4:2:0 has half vertical resolution chroma, but it achieves it by vertical sub-sample filtering, not discarding alternate lines! (Or it should be)

The Sony decoder simply discarded alternate lines of chroma, and repeated the previous, and would have given you nice jagged alias edges I suspect - if the CRTs had been sharp enough for you to see them...

The 1980 ITV franchise auction

Was STV and tvs the only medium companies to have a full time drama department? The amount of dramas it pushout to the network is alot more than just taggart.


Anglia made a reasonable amount - the PD James Inspector Dalgliesh adaptations, The Chief, Tales of the Unexpected, and a few other shorter run dramas. They were usually pretty well made, and not 'lowest common denominator' stuff.
