[dvblast-devel] Dvblast and CAM Dre Crypt PRO

Wed Mar 14 11:49:35 CET 2012

You can play on streamer using VLC any channel perfectly and on remote PC using VLC with stutters? Are not you are hitting also bursting issue? I guess I have disussion last week on this issue here…no big feedback. 

Well, can you please confirm me that Alpha Crypt Classic Pro 

http://www.alphacrypt.de/AlphaCrypt-Classic-PRO.7.0.html

Is realy for pi-sys  ? I am not expert for this and multiservises CAM is big theme and easy to gather 100% info. Which services you are recieving using this?

We are using the AlphaCrypt Pro module, which is capable of descrambling up to 7 services.

Our card is for cable operators, and is officially allowed to receive those channels simultaneously by the media content owners, so I guess it's also fine. 

Stream is not disrupted - if you watch it with e.g. VLC it plays fine, but if you watch with some poor STB, i guess with small buffers, it either stutters (picture pauses for moments) or produces artifacts.

When inspected with e.g. TS reader, there are no CC errors, so i guess there are timing issues. Playing with dvblast's latency and retention options does not help at all.

Hi,

you have reached more than one channel for some pi-sys ? For me work only one simultaneous channel at time. When second enabled result is unusable cause card is resyncing, so disrupting steram. As far I studied it is intentional anti-card-sharing arrangement in this encryption system. Fix me please.

I have to note - if in same transponder are aditionaly FTA channels you can put them into same dvblast config, it does not have influence, in this point dvblast works perfect.

I'm also experiencing similar problems with AlphaCrypt Pro and Irdeto Kappa cards (5.7, pi-sys). The more the channels, the more the stutter.

Hi,
are you sure that CAM allows simultanous decrypting of multiple channels?
This symptom I know from new Irdeto (pi-sys). If you will change config files to stream just one channel (only one SID) then issue
can dissapear. Try how many channels it can decrypt then will have idea. Bellow I see it is trying 5 channels to handle?

I recieve  FTA channels SOUZ and TopShop from transponder 12 303 L, and stream it to my network.
All is well. The stream is smoth, in tcpdump no delays on packets. My PC receive this stream and play it perfectly. No artefacts,
delays etc.

But one has only to insert the CAM DRE-CRYPT, immediately ш have little freezes.
Once every from 2 to 10 seconds the stream freezes and resumes. I see it in tcpdump output. In this case my PC recieves streams, but
picture is poor. Sound is freeze, Picture is broken.

With the CAM modules for other encoding is no problem.
Also, there are no problems with single-channel unit DRE Crypt.

How can there be a problem?
What to see that the twist?

Here is some diagnostic information ...
