Clock sync |
|
|
Can anyone tell me which, if any, channels on Sky Digital carry a clock sync
signal and whether or not this is available on the co-ax outpout of a
Digibox?
I am on the continent and just bought a DVR which I would like to sync to a
UK time signal. Unfortunately, the auto clock function will only sync to an
RF source and not to a Scart input.
Although we have BBC 1 and 2 on the cable, there is no clock sync signal
available on those cable channels whereas the is on some continental
channels (e.g. NL1).

I've never heard of "clock sync" on a TV channel?.
Perhaps you're referring to 'analogue' teletext signals?, which some
VCR's use to set their clock (with varying degrees of success!).
Teletext have a clock in the top corner of the screen, and suitably
designed VCR's can read this to set the time - it's not 'synched'
though, just updated every 24 hours or so.
There's no 'analogue' teletext on the satellite transmissions anymore,
so presumably your cable channels come off satellite? - the satellite
signals not use digital teletext, which is no good to your VCR..

OK. Sorry for my ignorance resulting in the use of incorrect terminology. |
I do indeed mean a reference clock signal. The strange thing is that the
traditional Teletext, in its current short form, is still
present on our cable with the clock in the top right of the screen but the
DVR clock will not recognise it. It does, on the other hand, accept the
clock signal from NL1 on the cable.

There is still "analogue" teletext on satellite transmissions in
varying amounts as shown by the availability of p.888 subtitles. If
the VCR uses the same part of the signal that feeds the teletext clock
then it is present on Astra 28deg on:
S4C Digidol
BBC1 London
BBC2 " "
CNN (although the displayed format is different from the BBC)
Travel Channel
Sky News (Ireland)
etc.

Just checked and there is teletext on BBC1,2,3 Sky 1 Sky News
with a teletext clock. CH5 has teletext for subtitles and a clock
Back in the days of analogue there used to be a lot of errors in the
teletext clocks of channels, the most reliable one was RAI uno
and prior to getting a decent time standard here I used it to set
the computer clock.

Useful to know Jim but my DVR does not want to accept any of them. |
Presumably because they are digital signals whereas the DVR clock is
evidently designed for the analogue teletext service as indicated by the
fact that it will only select channels from the analogue tuner. That is why
I was asking if the clock signal would appear on the RF output from the
Digibox. I have tried the channels you mentioned and the TV responds with
'No teletext available', so I guess that's the end of the matter.
On the other hand, I could ask my cable company why the teletext clock
signal doesn't work on BBC1 & 2. The chances of getting a sensible answer
are slim.

Presumably the sub-titles do not carry a clock signal. |

In fact there is still some. Many channels have a few pages and all of
those carry the clock data.

They aren't. They are analogue teletext.

Reboot your digibox.
Not all Sky digiboxes output analogue text all the time. This seems to
be a firmware-related bug that varies from time to time and box to
box.

I've just been and checked (on BBC1 only, as I haven't got all day),
selecting page 100 gives a message that analogue teletext is no longer
broadcast, and has been replaced by a digital service, BBCi. However,
the subtitle service on page 888 is still provided.
BTW, there was NO clock display on page 100!.

OK, no 'usable' analogue text service, and BBC1 certainly doesn't
display a clock on page 100!.
As you can't change the page a VCR looks for the clock on, which is
presumably page 100?, then it's useless.

Maybe it depends on the region, I'm certainly seeing
a clock on page 100 on BBC1 right now.
using an Echostar DSB 770 FTA
However, using the digibox its a different story so
perhaps the recent software change has removed
the facility to insert teletext ?

Indeed it is true that analogue teletext, with a clock display, is available |
on BBC2 at the rf output of the Digibox. However, my DVR auto clock setting
will not recognise it, even though that channel is set to all the parameters
of a UK RF signal.
If I scroll up to NL1, the clock immediately sets itself to continental
time. I just do not understand.
It is probably the same reason for not being able to download the Guide
Plus+ EPG.
