What does it mean when someone is listening on 'cans' in talkback?


Exactly that I imagine!


lol Wink I mean what does the term 'cans' mean in relation to talkback?


I suspect someone, like a floor manager, listening to the gallery on a pair of headphones.....

Cans - slang for headphones.


Ahh right. I really should stop with the questions now - I've just got too many coming at all directions! Thanks for being such a helpful and patient bunch though Very Happy

i have a tape in which i recorded an nbc feed from 1986, their affiliate news service used to be called skycom but now they changed it to news channel (reminds you of the now defunct ITV news channel)
It was very nice - the intro was composed of color bars plus the a picture of the Statue of Liberty with the date. All of this was accompanied by "The Mission" playing in the background. Following was a narration of the stories to come plus some changes from the list that appeared on screen

the video is different: It starts out with a quick NBC Nightly News ID (note the pre-Mission theme). Then are a few vt countdowns to different stories, including one from KNBC. Finally there is the intro to the NBC A News-1 promo feed, with "The Mission."

The APTN feed on the run up to each hour play out The World Live from Earth TV where you can cut in live up to the hour for the longer feed than what Sky Travel show, followed by a compilation of time lapse and highlights with the occasional promo.

Then it jumps back to the rather BBC Newsline looking holder clock and menubaords!

When a programme does a live 'down the line' interview or 2-way with a reporter or guest, the audio in their earpiece is known as 'Clean Feed'. It is the programme sound minus the audio from the line - so the reporter/guest doesn't hear their voice come back in their ear.

In some places this i known as IFB - Interruptable FoldBack


Also known as a "mix-minus" in some parts Smile

I was surprised when I was at a BBC OB in Belfast where the audio the presenter and crowd of assembled people heard was the actual programme audio off BBC ONE itself mixed with the gallery sound, not only was the ident and continuity played through, but the sound was turned down once studio presenter had asked OB presenter a question and turned up again after.

Only noticeable when you watch it on BBC ONE and hear the echo you get with telephone callers and a director feed in the background so also on you would also hear "CUE OB" blasted through and a second later on the BBC ONE feed.

Then again it was the Stephen Nolan show where they do like to overemphasise the liveness of the whole thing!

Some sort of lash up because the talkback had gone down perhaps?

I think this thread's a good example of how the same term can have umpteen different meanings in television!

What is a 'legalised' copy/roll?

Since producers don't always pay as much attention as they ought to, distribution tapes are run through a bit of kit known as a legaliser before the transmission copy is made - which just makes sure that the video doesn't exceed the specified voltages, etc. (This is often done as part of a tech review, which will also check for flashing pictures which could be harmful for viewers with photosensitive epilepsy)
I heard a story about a Janet Street-Porter programme on BBC Two (possibly DEF II) which had its colours and brightness whacked right up beyond the legal limits; and fell off the air because of it. I'm sure someone here will be able to fill in the details about that...

What is the backup copy? Is it simply a standby tape if a show can't go live with a complilation of best bits?
A backup copy could just be a spare copy of a programme tape - as reliable as videotapes are these days, they still break sometimes. It's slightly different from a standby, though.
Any programme that's live or delivered late will have a standby programme scheduled against it, sometimes more. Live events (eg sport) will have various standbys of various durations, in case the programme finishes early or the OB goes down, or in case it over-runs and later programmes need to be dropped and replaced with something shorter. These could be anything that's considered appropriate for the timeslot (but invariably on the BBC seem to include Animal Park).
Sometimes a standby will be a 'best of' programme - Newsround generally has a Newsround Extra as a standby, and Watchdog has 25 Years of Watchdog. I think I've seen Airport as a standby for Question Time though, so it doesn't always make sense. There's even a standby tape for Two Minutes Silence.

Do they still use tapes to keep stuff on these days? Or are they all considered old hat?
Generally yes - for a start, you're going to have trouble getting more bandwidth than a van full of tapes. They're a fairly safe bet for long term storage, and they're not going to crash or be corrupted just by sitting in a warehouse (unless the roof falls in, or something ridiculous like that).
That said, TV playout is generally done from server, so programmes will be delivered on tape and ingested onto server, and Flextech are moving into a tapeless environment: they'll get a distribution tape, it'll be ingested, and they'll do all their compliance edits, promo-making, subtitling (etc), and playout from server copies, rather than passing round tapes.
It's not entirely tapeless, though - the MPEG files are moved on to data tapes, which are kept in a big automated data archive vault thing for long-term storage.

I hear that it's possible to view these sorts of things on the BBC's TV system in the newsroom at the touch of a button - is this true?
You can usually pick up the output of most of TV Centre's studios from within TVC.

Inspector Sands posted:
A news programme normally record a 'clean' of the studio output and then keep the cut items seperately and normally both will be kept in library. Clips of the programme such as interviews can then be used again, as can the cut items which will have 'split track audio' so the voice-over can be removed
Ah, that's an interesting point too - news VTs will be recorded with interviews and camera sound on one channel, and voiceover on another, then this will be mono-ised before transmission: which, as Mr Sands says, makes things easier for archive use.

Laughing Interested in a tv career in general but always good to have high knowledge in terms of the technology too.
