Descrambling with TBS6909

[RobCee]

Hi,

I was originally looking at a MOI Pro AMD for putting 4 x TBS6909 cards in however I was advised that I wouldn't be able to descramble many channels on the MOI Pro AMD as it was not powerful enough as descrambling takes a lot of CPU power.

If I was to use a machine with 2 x XEON E5520 processors (dual quad core) would this be better? If so how many channels could I descramble with this at once?

Many thanks,
Rob

afaik, you hardly need much CPU - only if you are trans-coding the video into a smaller format.

my raspberyr pi3 can descramble 4 channels at once no problem..

If I have say 10-15 streams going with tvheadend with CAs would this not cause high CPU usage? I was told descrambling uses a lot by TBS

think it's not that much..
don't know what cpu is in moi pro... but with my quad core xeon 1225 v3,
i don't see oscam going over 0.3% cpu descrambling 2 channels, but i think the work is done in tvheadend anyway..
tvheadend is showing about 10% CPU max, but hovers around 7% (of 1 core) with 2x HD channels, being descrambled.
