Simulcrypt with nds - freezes and glitches?

Re: Simulcrypt with nds - freezes and glitches?

Requests to card are asynchronous (they are not serialized in queue) so the scenario you are representing does not take place in reality.
Facts show that an oscam server with a slow (0919 caid) card can serve up to 20 users without glitches. I can't confirm myself, but this number could be even higher.

Oscam uses a different cw-management as cccam. Once decrypted the ecm, it will keep the cw in ram and can answer a lot faster if the same ecm-request comes again from another source.
Cccam gives every ecm to the connected card even if it's the same ecm again.
If there come more than 4 or 5 ecms from different channels to the same card, you have to wait a second untill all are answered. This could be too long and cause glitches if the even cw is sent only 0,6seconds before cw-change.

With my experience, the same type of encryption system behave different on DVB-S and on other HD channels like DVB-S2. For Sky-it on 13E have almost no glitches on DVB-S channels and have many on DVB-S2 channels. Here is also processing of STB also involve. Its my idea

You mean the same box and the same cline?

They may be caused by the usage of dvb-s2 to dvb-s.
Do the use the same caid or is it different?

Yes, same Ca type but different behavior on same C-line

Re: Simulcrypt with nds - freezes and glitches?

The same cline means same server which is connected to many cards. The most servers have more than one card for the same provider.
In your case it sounds that there is a card for the HD channels and another one for the sd-channels. The hd-card has more usage than the sd-card. This means a bit waittime and eventually glitches in the stream.
The SD-card is lower on usage and can respond in time to avoid this.

Then it's your choise: HD with glitches or sd with none...

Is your experience related to a server with two cards ? (I mean one for SD and one for HD)
In my experience one card can serve both SD and HD channels with similar ecm times.

Re: Simulcrypt with nds - freezes and glitches?

In my experience with this site clines, I' ve never noticed differences concerning glitches on sky it between HD and SD channels

You are using server3 and server4 clines?! Then you'll have defenitly freezes and glitches. Then it's difficult to differentiate is the glitch or freeze because of a server disconnect or the behavior of nds-cw management.

Interesting would be if you notice this behavior with a stable premium server.

Re: Simulcrypt with nds - freezes and glitches?

I have a premium pay line for sly uk, and can confirm that I experience very little freezing/glitching.
Occasionally on weekends I might get the odd glitch or 2, but I'd put that down to the server being busy. I watched a movie last Saturday and had 2 very small glitches during the entire movie. Weekdays is pretty much glitch free.

Re: Simulcrypt with nds - freezes and glitches?

There was something strange going on the other day though. Sly sports 4 was showing ecm of 800 ms and more. Ecm was up and down like a yoyo and glitching badly.
Program showing was highlights of a cricket match, so couldn't be down to server overload.
Tried a dozen or so different channels and all were fine, ecm around 150 ms and no problems at all.
Just on one channel.
Sly uk doing some tests maybe?

They have defenitly started some testings.
But their problem is that this can also affect the normal subscribers.
Perhaps that's the reason why they did this on a not so often watched channel.

I' ve used server 2 before new forum's rules. sometimes 1-2 gliches or freezes /hour independently Hd /Sd

The main question is that if there's a difference in freezes and glitches at a stable server when you change the cw-system in a simulcrypt system.

E.G. sky_de uses caid 09c4 and caid 1702.
Are there differences in the performance when you ignore 1702 and prio 09c4 in the prio file?!

Hi ivngat76
In my experience with line server two it depended from day by day.
sometimes 1-2 gliches or freezes /hour independently Hd /Sd or more.
However server three and for no good for significant test.

You have a server 2 line? Then you can test and report.

Is it possible for you to examine a tv-program from sky_de on 19,2°?

They use simulcrypt with nds.

What happens when you ignore 09c4 and prio 1702 or 1722?


I: 09C4
P: 1702
P: 1722

in the prio file and after that:

P: 09C4
I: 1702
I: 1722

Do you realize changes in performance?

Thanks in advance
