Yep feeds like this are out there, for example with a Scottish Premier League match on 10E, there is a dirty feed with Setanta's scoreboard, commentators and visual effects, and a clean feed, with no scoreboard, commentators or visual effects sound, you just get to see the transitions, it's all very interesting, enough to get myself a motorised dish one day.


Yes, very interesting - I would never have imagined so much from off-air would be kept. So...

After a show has been TX'd - you have a master copy, an off-air copy recording what has actually being broadcast and not just what the gallery has recorded, clean copy, dirty copy, A-roll, B-roll etc (still not absolutely sure what the differences are between all of these - would be great to have someone clarify Wink ) and all the individual VT's which were transmitted - correct? Confused

Any idea of what would be kept from a live broadcast with regards to rehearsals and the like? So basically when everyone at home would be seeing VT's on-screen the gallery would have a seperate tape with everything going on in the studio too.


What I think is that where there are VTs in the actual transmission, the channel is playing idents and commercials.

I've got a couple of images from studio broadcasts that aren't transmitted to viewers, these are basically satellite feeds to receiving stations...

ITV's Soapstar Superstar - during live transmission, i.e. they cut into adverts

Channel Four's Space Cadets - after transmission

Sky Sports Champions League

American NBC's Today Show rehearsal, interestingly (or not), what they tend to do is for the each affiliate NBC station to broadcast at one time this feed as the anchors explain to that affiliate what's coming up on the show. This showed them doing a 5 minute preparation of the headlines and introduction.

NBC's Nightly News - preparation for affiliates and CNBC Europe

MSNBC's Scarborough Country rehearsal

BTW I think clean feeds can actually involve graphics. For example the golf now on the BBC, the BBC are using a clean feed as there is no american commentary BUT there are graphics present.


Thanks edward for the feed pictures, it's always interesting to see feed pictures, yep mostly the best place to find feeds are on 16 degrees E, 10 degrees E, 22 degrees W, 15degrees W and 12degrees W and 1degrees W, hopefully one day, I can search for feeds as well, it's all fascinating stuff behind the scenes.

Yep clean feeds can involve pics, if the pics are from source, if they are embedded in the studio gallery, then the feed will not have graphics. Occasionally 28.2E let slip the odd feed here and there as well, but very occasionally it has to be said.

Legalised copy - in the journalistic sense - is copy (ie: script) that has been "legalled" by a lawyer for possible infringments of reporting restrictions or other legal obstacle. The same is true of a "legalised copy" or "roll" of videotape. A package or report may have to be legalled as a finished edited piece to avoid dematory remarks or court restrictions on a story.

As straight forward as that then. Thanks.

Anyone know if any tapes of rehearsals during the live show are kept?

Believe it or not, it's actually quite unusual for recordings to be made of rehearsals. The only situation I've seen them used is so presenters can watch back before live transmission to tweak their delivery of certain items.

Weird isn't it? Confused Surely it would be nice to have a copy of everything that went on in the studio that excluded breaks for VT's, adverts etc. Oh well!

But then again, think of the amounf of space ot would take in the archives to keep rehearsals, clean feeds & raw footage. It would be massive, and doubtful to be financially viable

Very true, just a nice thought I suppose.

Do they still use tapes to keep stuff on these days? Or are they all considered old hat?

And those feed images? Are they transmitted in the clear on satellite?

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?

If you were to pay for a copy of a programme from the archive, what would there be where the adverts had been broadcast? Would the ads be included on the tape? I only ask because I had enquired about purchasing a copy of a news programme from UTV and was wondering if there would be anything interesting on it!

No adverts. I'd assume all you'd see where they would be is the VT clock, if that was even left on seeing as you're paying for it.

From my experience they still use tapes.
