Titel: TS Sync byte not aligned
Beitrag von: therock am April 23, 2011, 07:58:21 Nachmittag
Hey

i just installed my new Sundtek SkyTV Ultimate onto my xbmc linux box

with kernel Linux XBMCLive 2.6.32-26-generic #48-Ubuntu SMP Wed Nov 24 09:00:03 UTC 2010 i686 GNU/Linux

and the tone and all that is fine on normal SD channels

but when i want to watch a HD channel it gives a pixel picture and this is what i got from the log file

is there anything i can do?

What System do you use?

Are you using any graphic acceleration for HDTV?

Please provide some information about the CPU load (eg. screenshot of top on the console).

please note that decoding HDTV with the CPU can take a massive amount of CPU and steal it from the driver finally corrupting the datatransfer.

So far we advice to use NVidia Graphiccards for HDTV since they have mature support so far.

but yeah it looks like it can't manage the load but if i play a mkv HD movie it plays nicely

so its not that bad on cpu

We're still missing the BER (Bit error rate) reporting in the driver it should be available early next week, that should help to go further with that problem.
HDTV in general is no issue normally.
Titel: Re: TS Sync byte not aligned
Beitrag von: therock am April 24, 2011, 01:20:22 Vormittag
okay looking forward to that...

anyway if i mount it in a very powerfull pc with the same kernel it should work with HD channels right?
Titel: Re: TS Sync byte not aligned
Beitrag von: Sundtek am April 24, 2011, 01:42:41 Vormittag
Let's check the statistics first.
Titel: Re: TS Sync byte not aligned
Beitrag von: therock am April 24, 2011, 04:12:20 Nachmittag
okay but if i put the same cable in my sat i get a fine signal so i dont think it has anything todo with BER...?
Titel: Re: TS Sync byte not aligned
Beitrag von: therock am Mai 10, 2011, 03:13:27 Nachmittag
is the BER reporting enabled or when will it be enabled in a new driver?
Titel: Re: TS Sync byte not aligned
Beitrag von: Sundtek am Mai 10, 2011, 04:37:20 Nachmittag
We are currently working on getting the Signal Strength into the driver, the problem is that specific part is missing from the information which we received from our chip dealer.

BER is basically no problem, we'll check it quickly tomorrow morning. Our main interest is the signal quality indicator.
Titel: Re: TS Sync byte not aligned
Beitrag von: Sundtek am Mai 11, 2011, 04:19:00 Vormittag
We received all the necessary information this morning so it will be available very soon, also we've been told that the driver for the S2 chip component is outdated. We're going to update it completely asap.
Titel: Re: TS Sync byte not aligned
Beitrag von: Sundtek am Mai 11, 2011, 05:29:25 Nachmittag
Just to update this, we updated the BER but are still testing how usable those values are and finding some reference values by comparing it with different devices on the market.
Good for us the BER value is always low but question is how correct this is so more testing is needed, we only tested those values for one day so far so more work is needed.

One thing we noticed is that the F-Connector of the LNB cable is a major point of failure we have several different cables for testing - the cable itself does not matter but the connector. Cables with a high quality F-Connector never caused any change of the signal quality when moving or touching this part. Whereas cheap connectors which did not connect both items rock solid could cause a drop of signal quality of up to 30%.

hi therock, did you manage to get HD working? I seem to have the exact same issue:

Titel: Re: TS Sync byte not aligned
Beitrag von: Sundtek am Juni 21, 2011, 07:28:18 Nachmittag
we're looking at it (but please expect the answer in 1-2 days), we can't answer before we finish some testing with new devices.

The device overall should be fine but sensitivity might need to be improved of your stickversion, testresults will be available soon.
Titel: Re: TS Sync byte not aligned
Beitrag von: druggo am Juni 27, 2011, 10:07:04 Vormittag
Ok, it has now been more than 1-2 days, whats the status?
Titel: Re: TS Sync byte not aligned
Beitrag von: Sundtek am Juni 27, 2011, 07:12:18 Nachmittag
We did some tests, basically if your LNB delivers a strong enough signal it should work without any problem.

However, we were working together with the tuner company within the last week and found a way to improve the sensitivity of our USB Stick. The sensitivity of the latest DVB-S/S2 stick is at least as good as with regular settopboxes (if not better). We also compared some other PCTV DVB-S/S2 devices (eg. TT S2-3650) and figured out that the latest revision (v3.5) has a much more sensitive tuner implementation now.

If you have purchased your tuner after 20. May we will replace the USB Stick for free with a new version, if not we will charge a small handling fee (basically shipping + 2 EUR handling) for upgrading the USB Stick, plus we need the old stick in return (only the USB Stick).

This upgrading option will only be available as long as devices are available at the beginning. Once the mass production has been finished in August it will be available until the end of 2011.

Rev 3.5:
* improved sensitivity
Rev 3.0:
* short circuit protection
* works without AC adapter with many active multiswitches
* faster inductor discharging (eg. when disconnecting AC adapter while stick is connected to an active multiswitch).
* stick shows up red light if something's wrong

I have 76% signal quality, should that be enough?

I ordered my stick 03.05.2011 19:53:59, order no 1946, however, it was not shipped untill mid-june..
Titel: Re: TS Sync byte not aligned
Beitrag von: Sundtek am Juli 04, 2011, 02:19:39 Nachmittag
Signal quality should be enough but we better replace the unit with a new one this month.

Hi i have received the new stick - and swapped it, too bad the same results (see attached logfile) i also tried to upgrade to the latest driver, same error (see logfile)

Anything else you want me to try?


with latest driver:

We already figured out this issue and are testing some different components for it this week.
 
We mainly use Astra 19.2 / Hotbird for testing, those satellites have different requirements compared with eg. Thor5. Anyway more about this issue will be posted within the next 1-2 days. That issue mainly affects northern Europe (scandinavian Area as far as we could figure this out) so our current plan is to provide different S2 sticks for that region.

Working on adding the features of the central European stick to the stick which is compatible with Thor5/Scandinavia.

We'll send you the current engineering sample which already works with it as soon as we have the next cut (1-2 weeks) so you have something to play around with.

Small Update:
3 handmade samples are ready for the Scandinavian market which solve those issues, the devices will be shipped out at around mid next week.
