I've seen the same info on usenet posted by somebody who should know.

This year's tests are as I understand it:-

Friday, 5th January, (Thursday into Friday for those freaks in Pres who think the day starts at 0600)

BBC ONE 0400-0500

BBC TWO 0230-0330
I haven't heard the exact timings myself, but I can confirm that the plans are indeed for early Friday morning.

Do DVD Recorders record Teletext? If so, I'll set that up to record the tests. If not, I'm sure the bog standard VCR will do. I don't want to miss something like PresFax do I Very Happy

They don't, no. A SVHS recorder should do though.

Is there a way to capture Teletext as a Jpg using a TV Card?

I'm sure there must be, but I've never owned a TV Card, watching TV on a TV is good enough for me Smile

I'm not sure if any members of TVF are interested but i have had ^unconfirmed^ reports from MHP that the BBC are planning a RBS Test on BBC 1 and BBC 2.

The test will take place on BBC 1 at: 0400 until 0500
and on BBC 2: 0230 until 0330

The test is usally accompanied by a 4-tone test tone, ranging from extremely low frequency to a very high shrill.

The broadcast is part of a switching test by the BBC. If there were ever a major incident at Television Centre, London, BBC Network Television would evacuate to the Mailbox, Birmingham. A switch would be thrown so that Birmingham were in control of the network, where they would then attempt to run as normal a service as possible.


This was in a thread opened and quickly closed in the Newsroom, but I thought it was worth pointing out that the RBS tests have little to do with plans to continue broadcasting should The Broadcast Centre become unavailable (the channels' transmissions no longer originate from Television Centre). Birmingham is also no longer the sustaining broadcasting centre.

The point of the RBS Test, as has been explained in a good degree of detail already, is to test the analogue transmitters' ability to switch to rebroadcasting their nearest transmitters' output should they lose the incoming network feeds.

Also, last time it was continuous tone with the speaking clock rather than the 4 pitch tone mentioned. Is the poster perhaps getting confused with the lindos sweeps used on the radio RBS tests?

I was rather disappointed with last year's tests - just Testcard J with tone and clock. Going back a few years I remember inexplicable slides and clips, such as a repeated clip from a piece of golf coverage including an overview of the 18th hole (?) then someone walking over to the hole to pick up their ball.

Maybe not a RBR test, but I remember a really trippy test transmission sometime in 1992 or 93 which was shown simultaneously on BBC2 and C4. I seem to remember it was in widescreen, and featured all sorts of geometric patterns, animated and sliding colour bars and spinning discs, cycling colours and rotating crossed lines. This was set to some really bizarre (but mesmerising) trance-like instrumental music. One thing I remember in particular was the dot-matrix caption overlaid onto this, reading "Engineering Test Transmission" followed by either "Camera Mode" or "Film Mode". The test toggled between the two modes, where the latter was - you've guessed it - filmised.

Many parts of it looked similar to MPEG test animations, and I do wonder if it was indeed testing compression. I remember in 92/93 seeing what looked like compression artefacts on C4 (but never on BBC2), but different to the sort we see with MPEG today. In particular, scrolling credits often set off a brief white 'spark' against the edge of some of the text - but always in one spot only - but just about every programme had one instance of this. I also spotted that where credits were on a plain black background, I could see pixellation-and-hold artefacts on that background - i.e. there appeared to be temporal encoding going on even then.

I didn't have a VCR from mid 92-mid 94 so I wasn't able to capture this. I would love to know if someone has it on tape, if only for the spaced-out music!

P.S. S4C had some great Night-Time filler music in late 93/early 94, when they sold no airtime - they used to show animations again with trippy ambient music, which looked very much like Media Player Visualisations and hence probably a little ahead of its time.

Either the drivers or the on board MPEG Encoder cut the VBI lines out, making it impossible to record them. That and I only get the Sky Box and Freeview on the cap card. If I had a good analogue connection, I would have just kept the PC on that night and run a batch script to save page 100 at the right time, but the roof top aerial seems to hate me. If only it was simulcast on Sky, that way I could have just stuck it on my Sky+ planner.

Didn't realise the tests were tonight (5th). I've just bought a new telly and good old analogue hasn't even been configured yet.

Is News 24 usually broadcast on digital when the tests are ongoing?

They're not tonight - they're 24 and a bit hours from now...

Digital services should continue as normal.
