Still missing segments!

Lawrence <lawrence@...>
 

Well, I must admit to being mystified. I have been monitoring the
receive computer and it consistently shows memory usage of about 130Mb
(very small proportion) and an average CPU of 1 to 2% with few jumps.
But still I am seeing huge chunks out of the HRIT images. But not all
HRIT images and not every cycle. The signal strength is excellent.

Alan, see my piece in next RIG journal. I have only _one_ place in my whole
house where I can see MSG-1. This requires a pole above roof level, and it was
a very close thing there too.

Robert


Quoting Alan Sewards <alan.sewards@...>:

Why don't you guys put your dishes where they are easily accessible? They
don't get any more signal for being on the roof and they are much more prone
to wind effects. Find a sheltered wall and use a sturdy wall bracket.

Best regards - Alan

David, I've been preoccupied with other things for a few days so have
rather
lost the thread on missing segments. I am still losing enough to make the
system almost unusable and animations impossible. Is there something
happening
that I can do nothing about, or is it time to call in the man the with the
ladder and meter from the local TV shop (costs me �72 a time here in the
hills)?

Could be worse, Douglas. My eToken on the new PC has stopped
working three time today already! 01:21, 14:08 and 15:04. Stops
all data flow and requires a reboot. At least you don't have that
problem!

Touch wood, the 15:15 is looking OK.

Cheers,

Thank you Arne that is useful to know - I have six to eight segments missing in
_every_ fifteen minute pass.
Looks like I may have to go up the ladder!

Has anyone else picked up a circular outine on the 1145 and 1445 CLAI

Same here. I presume that some part of the cloud classification

Yes, I found that after a little looking. I have tried to find the
specs of the B2C2 chip and other component of the SkyStar card, in
the hope of finding something more like an engineering manual that I
could understand! The B2C2 card is purely digitial, so that doesn't
help, I can't find the part number for the tuner, and the chip next
to it is hidden under a heatsink!

In any case, if all these cards need lower signal strength to
perform well, shouldn't AGC be doing something about that? Is "our"
transponder being hidden in a mush of intermodulation from the
others?

David

Robert, there have been some issues today, but the 16:15 cycle just
completed seems perfect. I only called in the "professionals"
because they had installed the system in the first place. I am
still waiting to see if there is a call-out charge. My approach
was: "Since you first installed it, there have always been problems
in windy conditions".

I think if you adjust it yourself, which monitoring the on-channel
Signal Quality indication, that should be adequate. That's what I
would do in the first instance....

David

Subject: [MSG-1] Definitions and questions!


Speaking from a position of ignorance, what is meant by "Signal
Quality" in the Transponder Status display? It seems to be rather
like the S-meter in amateur radio, an arbitrary indication of signal
strength as seen by the receiver (so in fact would be more
accurately called quantity than quality!). Am I correct? Is there
a standard?

Having asked that: why would adding a splitter increase the signal
quality? (OK, receiver overload would be less in a lower signal
level situation). But if the quality is actually measuring the
quantity, then it should indicate less!

Or is the kit simply so cheap that any absolute indications from it
should be ignored?

David

David,

I think the major difference is that signal quality is assessed after demodulation and takes into account channel power, carrier/noise and bit error ratio.

I have now reverted to my original setup with the PCI card fed through the loopthrough of a digital satellite receiver. The receiver shows the 11096 tp Signal 88% and quality 100%.
Whether connected via the loopthrough or or directly from the LNB there is no change in the Setup4PC Quality, SNR or BER. I have a splitter somewhere and when I find it will feed the PCI card and STB from the same LNB and see if there is any change.

My lost segment problem is now a thing of the past although a few expletives were expressed at midday today !

Google searches have been interesting, "DVB signal assessment" turned up the a paper on the reproduction of the newts !

Cheers,

Peter

all data flow and requires a reboot. At least you don't have that
problem!

Touch wood, the 15:15 is looking OK.

Cheers,

Data channel 2

I think best just to close down until the channel 2 problem (started about
midday) is resolved.
No software could deal with this !

David,

Having once again read the following :-

http://www.tellique.de/tq_tellicast/filebroadcast_p2.html

Do you think there could be errors in the dynamic key generation
on the Tellicast server. I am not refering to the encryption which
is not yet in place.

If the generation of the keys which enable each Tellique Client
User/Password to receive specific data channels and files become
corrupted this would explain why these problems are user and time
related.

Peter, as I understand it, the encryption is in place, but the
access to the encrypted files is currently open. There are
certainly files which only some people with eTokens get, and the
eTokens are matched with access control on the broadcast.

I would be very surprised if there is a key generation error on the
Tellicast server, affecting just certain users, at certain times,
and on certain channels. However, if the SNR remains good with no
uncorrected blocks it could certainly be an explanation. I have
certainly seen this problem, and I do use an eToken to access the
data stream.

Perhaps this is something that those affected should take up with
Eumetsat? A report here would be read by Eumetsat.

Cheers,
David


Definitions and questions!

Speaking from a position of ignorance, what is meant by "Signal
Quality" in the Transponder Status display? It seems to be rather
like the S-meter in amateur radio, an arbitrary indication of signal
strength as seen by the receiver (so in fact would be more
accurately called quantity than quality!). Am I correct? Is there
a standard?

Having asked that: why would adding a splitter increase the signal
quality? (OK, receiver overload would be less in a lower signal
level situation). But if the quality is actually measuring the
quantity, then it should indicate less!

Or is the kit simply so cheap that any absolute indications from it
should be ignored?

Cheers,
David

I don't know if Hotbird 6 has an analog transponder.
yes, there are a few analog PAL transponder in the same polarization
and band segment as the EUMETCast transponder:

10815H Duna TV
10974H TRT International

There are also some in the other polarization:

11079V France5/ARTE
11114V BBC World
11161V DW TV

If anyone has an analog receiver, you might want to try tuning the
channel, and then switching to the other polarization, to make sure
you don't see any spikes for the transponder in quadrature. If there
are traces of the signal, it means that the polarization angle of the
LNB is not perfectly aligned, so the LNB would need to be slighly
loosened from its support, and rotated in order to get rid of the
interfering channel.

Old trick from the analog world, not really applicable with the
digital birds any longer... infact digital TV is much less
susceptible to such misalignments, but in our case we're clearly
eating all the margins and accurate pointing becomes mandatory, as in
David's case.

Re: SkyStar card versions - calibration differences?

Could be a shared IRQ David. Did you try the Old card on the 4.2.8
driver too ?
Mouse judder: DVB card IRQ 09, Mouse IRQ 12
Looking at "Resources by connection" shows that the mouse on (ISA)
IRQ 12 shares that with nothing, but the DVB card on (PCI) IRQ 9
seems to be charing with the sound card, the video card, the network
card and two USB controllers!

Interestingly, on a recent PC most of the PCI IRQ values are
different, but on the 1GHz PC all are at 9....

Testing different hardware revisions with the newest driver and
SP4 is quite a bold step David. But if it works, does prove that
some previous error reports on 4.2.8 and Microsoft patches might
have been just a unlucky coincidence.
Well, when you install the new card the drivers on the CD are
V2.4.8, so I presume that they may be required....

Monitoring CPU load is required, unfortunately I don't have a tool
to measure the current harddisc load. Both are very important.
It seems to me that it is something more like a timeout issue rather
than absolute CPU or disk load - if the DVB card doesn't serviced
within a certain interval data is lost. Of course, there is nothing
like enough buffering on the card. If there was 30 seconds, say, of
data buffer (about 8MB, say 16 or 32MB for good measure, I am sure
the card would be much robust to use in a general purpose PC.

By the way, I see on MSG animator that the clouds are just
clearing
over here at this moment, so I might enjoy the moon eclips this
night !
It was cloudy for us in Edinburgh.

Both PCs have a PS2 mouse.

What I found with the testing PC (2.8GHz P4) was that whilst
most "office" use of the PC did not produce missing segments,
running anything that was very CPU intensive could result in
segments begin missed. E.g. making panoramas, and some Paint Shop
Pro filtering or resampling operations. Eating CPU for more than
(say) one second was not on. (On the other hand, running disk
defrags, anti-virus, Zone Alarm etc. seems to be OK. Perhaps
because they involve I/O as well as CPU activity). I had hoped to
be able to run the DVB card on a general "office" PC, but that
proved not to be 100% reliable.
