The "hidden" TCW on DTT channel 105 hasn't had a mention here
for some time, and I've just noticed that it's not as hidden as it once was.
The 33582RGYB key-strokes are no longer required.
So to get it you key 105
press yellow
select any other channel eg. 1
go back to 105
press green
a status page is displayed which invites you to press green for the test
card.

Coo. So it does. Is there any reason why this test card isn't more
easily available?

I get TCW, but it looks a bit ropey -- I presume it's there either just
as an easter egg or for very rough checks (e.g. the size/shape of the
raster), rather than to test frequency response or suchlike as the
various detail is rather obscured by artifacting!

Is it not rendered as an MHEG object ? Therefore you can't really validate any
over scan parameters, because I doubt the MHEG decoder in the receiver applies
any accuracy to such matters. The same applies to the image geometry.
The test card that is transmitted (as real video) on the BBC HD channel, shows
perfect (lack of) overscan, while as you can see from my photo the same is not
true for the MHEG version.

Yes - it's compressed to the hilt, cropped, and the geometry is wrong.

If you're lucky enough to receive BBC-HD, the promo loop apparently has
a few minutes of (a mildly doctored) 1080 version of TCW.

The annual Analogue TV RBS Tests are in the early hours of Monday
12/1/2009. The times will be 0230-0330 for BBC2 and 0430-0530 for BBC1.
These tests normally take an hour per service and comprise of testcard
and tone being transmitted instead of normal programme.
Some changes for this year. Ceefax will be radiated with the testcard.
Additional tests in Scotland in the the last quarter of the hour of the
tests.

I didn't, for obvious reasons, copy the full email. One "difference" in
Scotland is that as there is no longer a CTA in Glasgow other measures
have to be taken up there to monitor it. This may explain the long gap.
Also Arqiva are taking more of an interest.

It is simply part of the MHEG application. Pressing the red button on
any of the BBC channels causes the Red Button menu to be displayed, and
pressing the up/down/select keys allows the viewer to scroll through the
menu and select an item. In exactly the same way, the sequence of button
presses described above causes a version of TCW to appear.

Any idea why you have to tune away from 105 and back again?

Although of course 'The Black and White Minstrel Show', ISTR was one of BBC

Makes it harder to find, I guess. I don't know why that exact sequence
was chosen, other than 33582 spells 'delta', which was part of the
image's filename. I seem to remember at least one digitalspy poster
spending (or wasting) some time trying to spell out the rest of the
Greek alphabet.
From memory, I think you had 30 seconds to press the next button each
time you tuned to 105. I don't know whether that's still the case, but I
can check tomorrow.

Surely a simultaneously recorded FR copy would be the way forward here.
Quite how the cut points on a 24fps FR copy could be reconciled with a
29.97fps NTSC tape also interests me

RBL links seem to get new syncs, and presumably the teletext data is regenerated ?
When Hannington is radiating CCI present on its input RBL feed, the blanking

It's over 30 years since I encountered this stuff, so my memory is very
shaky, but audio and video are demodulated to baseband. IIRR both RBL
and RBS receiver video outputs are fed through stabilising amplifiers
('stab amps') which regenerate the syncs and correct the chrom/lum gain
(using the 20 猶 bar with 700 mV of subcarrier in the 2nd ITS line as a
reference).

The video is fairly ropey after a few RBS chains.
In fact Sutton Coldfield's RBS is Oxford. In the old days, if SC needed
to work on the incoming lines from Brum, it wasn't unknown for them to
ask us in Birmingham Comms Centre to tweak it a bit to rebroadcast!

This has always been the case, but for some reason this year my spies
tell me there is a change:
The times will be:
BBC1 0300-0400
BBC2 0430-0530
I know the timing is a bit dependant on programme content, so perhaps
the test organisers have had to shift things around at request of the
BBC Editors. If I find out the reason I'll let you know.

They tried it at TVC once in the 1970s, and of course the BBC had their own
name for it which was a set of initials though I can no longer recollect
what they were.
It was never put into practice though. I think they must have come to the
conclusion that it was indeed a very clumsy system, though it's surprising
they actually needed to try it out in order to realise this.

I monitored it on BBC2 from Winter Hill and (I think) Moel-y-Parc
using a carefully-placed indoor aerial.
The switchover for Moel-y-Parc was much less smooth, with a shorter
period of black screen and subsequent picture jumping for a few
seconds.
It also seems that neither site's RBS are dependent on each other; M-y-
P picked up RBS while my WH screen was still black, so isn't a relay
of WH. And WH continued to show an RBS'd test card for several minutes
