NBC News, MSNBC, ABC News and others from across the pond

Yep - an umbrella makes sense in the UK in most rain, it doesn't make sense in very high winds like these, so a hat makes a lot of sense...

However in the UK, unike the US, a baseball cap is relatively unusual, and usually a bit of a 'fashion victim' kind of statement - as they historically haven't been a part of British culture (we don't play baseball...) and are (or at least were) seen very much as an 'Americanism' (or a 'we're just back from holiday in the US' statement).

In the 80s I often heard baseball caps called 'IQ Reducers' - as the minute you put one on, you looked a lot less intelligent... Those times have changed - but wearing one in the UK would be seen a bit differently to wearing one in the US.

You can also enable EIT p/f triggering in TV Headend and other open source PVR apps. Freeview, Freesat and Sky also use it I'm pretty certain.


That's interesting. I have DVB-T2 and DVB-S2 TV cards and use SmartDVB and, sometimes, DVBDream and DVBViewer. I've never known it work reliably with that. My experience in the past (2015 and earlier) of Sky+ was unreliable too in terms of recordings being cut off if a programme overran, even if the EPG was updated.


The EPG updates are a separate issue - as the EIT p/f is sent slightly separately to the EPG (Sky and Freesat use proprietary EPG schemes, but respect EIT p/f - which is why you get Now/Next listings on non-Sky/Freesat receivers even if you don't get the full EPG)

If the scheduling system is a mess because they can't keep up with very last minute decisions made in playout, then there are occasions when EIT p/F doesn't work properly, but they are quite rare. It works surprisingly well most of the time (and is effectively fed by the same backend triggers that would have updated / triggered PDC I think)

Most DVB capture software for PCs doesn't use EIT p/f by default, and instead offers pre- and post-record padding as many broadcasters across Europe don't use EIT p/f dynamically as the UK broadcasters do. (Suspect padding on Sky+ boxes also masks the accuracy of EIT p/f)

TV Headend does support it - and supports it well.

BBC News Channel Presentation - 21/03/16 onwards

I've always found it a rather strange and awkward arrangement (on a typical weekend) for one of the Breakfast presenters to have to make an apology to leave the programme ten minutes before the end 'to go and read the news for Andrew Marr'.

Could they not just cut back to the Breakfast studio for the first Marr bulletin to avoid this, maybe with the background on the plasma screen changed to a newsroom image?


That would leave you very little time to check comms with the news presenter (their talkback feed would need to be switched), switch Autocue to a different show order, confirm story order with presenter etc. (I think the news bulletin VTs are played in by the London gallery, and scripts are in the Marr running order.)

Despite its flaws, I don't think anything exists in this day and age that even comes close to being a simple and reliable way to making sure a programme is recorded in full. Even Freeview/Freesat PVRs seem to struggle if a programme is running late as, in my exeperience anyway, the EPG isn't always updated and/or the recorder doesn't pay attention to any late changes.


Properly implemented DVB EIT p/f (Present / Following I think) record triggering works pretty flawlessly in my experience on the BBC channels. It's triggered by the action of playout in the suite. It won't cope with programmes changing channels - but if the programme is still scheduled correctly, the record start is usually pretty spot on for the ident introducing it.

The BBC use EIT p/f triggering to index BBC Redux, their internal off-air archiving system and it's very unusual to find a show on that which has a dodgy start or finish.

You can also enable EIT p/f triggering in TV Headend and other open source PVR apps. Freeview, Freesat and Sky also use it I'm pretty certain.

Challenge - June 2016 onwards


Real Lives is more associated with Pick and Challenge, of course, but they can’t convert the channel to FTA whilst they have the archaic three channel limit that Ofcom imposed on them when Freeview launched - their share of the capacity has not proportionally grown compared to the likes of UKTV, Sony and CBS.


Though last time I checked UKTV, Sony and CBS didn't own and operate the largest pay-TV platform in the UK either. Why is the rule archaic? I don't see Sky's position in the market has changed hugely.

International News Presentation: Past and Present

Comparison of Tagesschau as seen in different ARD member stations:

Love videos like these, fascinating, NDR cutting it very fine, BR opting out of the national weather to do their own weather, then most of the rest opting out before the end of the show.


Having a pause at the end of the weather to let stations leave before a trail for a show they probably won't take is a very neat solution.

I'm not sure this is a case of 'opting' though - isn't this a case of joining for a specific show? (Though I suspect in some areas that would still be described as an opt, as it is optional.)

Early days of NICAM Stereo

This is a TOTP performance from May 1988 in stereo. The Radio 1 FM simulcast didn't start until September, so it appears they were producing the show in stereo long before then. I wonder when stereo TOTP broadcasts started from Crystal Palace.

Wouldn't be surprised if they were stereo from the start of the CP tests. There was a reasonable amount in '86 or '87 from memory.

Early days of NICAM Stereo


Were there multiple flavours of DSIS? ISTR that there were various flavours of one type of SIS or the other.

From memory the BBC used Dual Sound-In-Syncs (aka DSIS) on the output of their studio centres to feed the transmitters - and the data format used for DSIS was identical to NICAM, so removed the need for NICAM digital encoders at every transmitter (instead just needing some shuffling and modulators)?


Other way round. The IBA DSIS was NICAM 728 based, so no transcode required between studio and receiver. The BBC used the same format as their national radio distribution, NICAM 3 ? 656kHz based, so transcoding required at the tx sites. The Beeb opted for that to make spares interchangeable between the radio and TV networks. The IBA were dealing with 'green field' so made perfect sense to go with 728.


That's a surprise !

Anglia/East of England News Discussion


Their gallery set up is pretty much the same as most other regional centres built or refurbished between 2000 and 2007 (Nottingham, Southampton, Newcastle, Birmingham and Bristol), only without a pres gallery. They're all overdue a refurb but there's a change in the way English Regions will be delivering their TV content, moving to a more ITV style system (changes in the Coding and Mux setup similar to ViLOR for TV)


I think that you're mixing up two potential changes (though they may both happen)

1. VILOR style TV production - with the bulk of the broadcast kit in data centres, and just the control surfaces and audio and video I/O on site.
2. Centralised opting (where rather than network being fed to the regional centres / or regional equipment in a data centre VILOR style - and fed back permanently - instead the studio output is fed to playout/coding mux, and the opt-out switch done there, as ITV do)

Early days of NICAM Stereo

Just some memories. Going from mono to stereo operation was quite a big deal for the ITV companies. Where I worked we moved over from analogue audio distribution to dual channel sound in syncs (DCSIS) for inter company programme distribution via postie. The DCSIS signal was somewhat prone to not working if it was in way distorted. It was imperative to ensure the signals incoming to 'your' building were properly equalised at the very front end (as they 'hit the building' in the PO bays) or the DCSIS decoders would simply object and you'd either get nothing or highly distorted and glitchy audio.

Internally of course everything had to change over from mono to stereo, perhaps one of the most overlooked areas is the question of stereo distribution and switching around the various sources and destinations around the TV complex. Internally, signals were still analogue (SDI was maybe a tiny dream somewhere) but at our company our 'old' analogue Probel audio matrix in CAR had to be replaced and it was with a Probel TDM matrix (Time Division Multiplex) - in essence the analogue audio feeds were presented to the matrix input ports, which then converted them to digital, which then switched that digital signal to the required output port, which then decoded it back to analogue audio to send to the correct destination. This new matrix also replaced the old analogue VTR matrix which was originally manufactured by Utah Scientific. Interesting times as ever.

Early days of NICAM Stereo

Why would they have struggled? All their transmission/playout was the same as Carlton and LWT, and I wouldn't have thought they'd not have upgraded their studio facilities in preparation for going on air


Didn't GMTV use existing TLS studio facilities? I don't think they built from scratch - so it could have been they inherited a mono sound installation in the studio they were using ?


The studio production floor (St5) was of course already in existence, all the other facilities and production suites were specifically built for GMTV as they simply did not exist and had to be ready for GMTV's rehearsals in Oct 1992. I think the first audio desk was an Amek, I'd be very surprised if it wasn't stereo capable. Long time ago.


Ah - you know far more than I do on the subject. I'd be amazed if it had been a mono install if it was a new-build.

Early days of NICAM Stereo

We had a retro-fitted early NICAM decoder installed in our VHS HiFi VCR (you used the Simulcast setting to record NICAM audio) and were watching and listening to Crystal Palace NICAM broadcasts from c.86 or 87.

Whilst technically they were 'test' broadcasts, the reality was that stereo production became the norm very quickly, particularly for live shows, and for recoded shows that went through a 'dub'. Shows that didn't go through a dub and were edited quickly on 1" or Beta SP were less likely to be stereo - as there are limited audio tracks on that format (and you used to have to use external digital lay-off devices ISTR)

ISTR that Yellowthread Street (set in Hong Kong with a decent budget) was the first ITV stereo drama.


I seem to recall the lay off device would have been a 'Bel box'? - pretty standard bit of kit throughout the industry during that period.


Yep - Bel boxes were standard in Beta SP suites working stereo. ISTR that some areas worked M/S rather than A/B too.
