lost/delayed segments

maxrpunkt
 

hi everyone,

since some days i have some troubles getting all segments. the specs of my receiving system are:
1.2m kathrein dish
2.4Ghz
1GB Ram
160GB HD
winxp pro
tellique 2.3.0a
skystar 2 dvb card with driver and software version 4.2.2

now i have some questions:

- is there a possibility to figure out where the segments are lost (without waiting for some eumetsat messages) ?
- was there a change in the dissimination in the past 3 days?
- if there are some segments delayed, how long it makes sense to wait for them. my image processor is adjusted, to wait at maximum 2 hours for delayed segments. segments ariving more then 2 hours after the first segment are ignored. may this 2 hour threshold cause the lost segments?

thx for the help!

regards, max

David,
I loaded my verbose files into MSWord and used 'find' to seach
for 'missing'. Every missed segment corollates with the log. I
note
that I received the file you missed. So diverse reception is the
answer? Now I will go and re-check my dish again. I guess that if
others are not getting problems then I am probably suffering from
localised effects, though the signal as per Arne looks good.

Regards David S.
So what I would like to know is what "missed" means:

- a momentary break in signal?

- a CPU load which prevents the Tellique software completing an
operation in a timely manner (timeout)?

- an inadequate DMA buffer size which causes a single operation to
be split into several parts?

- a shared IRQ line which prevents timely servicing of an interrupt
or even the loss of an interrupt?

- a load from the network while transferring the current data for
processing, preventing proper reception of the next block of data
coming in?

- simultaneous data on Data Channels 2 and 3?

It's a genuine issue, ad we really need a guide to minimising or
eliminating the problem.

Cheers,
David

Well, look for the words "missed" and "lost". I have verbose
logging enabled - perhaps you do as well. But particularly, look
at
what is happening when one of the missing segments should have been
received.

John,

I loaded Microsoft update V4 this morning with no complication whatsoever
(running XP-pro). The KB824145 you refer to is not mentioned on my machine.

Cheers,

Hello All,

I installed the latest Microsoft security update (KB824145) to my processing
computer this morning and it got stuck in a re-booting loop once it
had fired itself up. I got it going in safe mode and restored back to
yesterday and now it seems fine. Anyone else had a problem with this
update?

David,
You actually need alittle more to see the real differences as the
clock timming is a little different.

It makes interesting reading but how do we interpret it. It looks
like we are seeing rather different signals!!

Re: Up to 2230 no missed segmenst

This takes the biscuit! I used my card to watch Sailing Channel and other TV
stations - following Arne's instructions - to check that my PC was coping with
data from Hotbird. All fine - I flicked through about 50 channels. I decided to
stop this and restart MSG-1 reception, but I was expecting to continue with
dozens of missing segments until a solution was found to our problems.
Since re-launching Tellique software I have had perfect reception with no missed
segments.
Ho hum ....

Missing Segments

David Strickland <David@...>
 

All I have just come back on air about 2 hours ago. I have changed
from a PCI WiFi card to an ethernet driven WiFi access point (WAP).
My reasoning was that if the amount of data from MSG had increased
then my WiFi card may have been taking resources that upto recently
were not sufficient to cause segment loss. It is pouring with rain as
well and I have not re-aligned my 88cm dish. I now use an ethernet
card to connect to a WAP which acts only as a bridge to another WAP
to my study network. Theory being that the WAP itself will now deal
with some of the work that the PCI WiFi card had to before. I have
had no missing segments since restart.I hope that is the way it now
stays. Will leave it running over night.

Checking your MSG system on a second signal source

a_van_belle
 

A lot of members are having MSG reception trouble at the moment. Looks like
part of these problems are caused by Eumetsat, but others not.
Yesterday I installed a DVB viewer on my receive PC.
This way you can watch TV and judge from a second source if your antenna,
skystar and PC are working correctly.
Viewing DVB does ask for more performance, so it will detect if your PC's
performance is to low for MSG.
I fully tested this program on my W2K PC were I installed the official
Eumetsat CDROM.
ProgDVB and Tellique do not interfere, but cannot be used simultaneously of
course.
Only drawback: after exiting ProgDVB you have to reboot before starting
Tellique again, I guess some buffers or memory addresses might not be
released.
In the files area I uploaded a PDF manual on how to install and setup this
program.

Using this prog I can view Sailing Channel without any blips, freezes or
missing pixels.

You can download the program from:
http://www.progdvb.com/download/history/ProgDVB4.07FullInstall.exe
Please do not use other versions as I have not tested these.
