[dvblast-devel] Dvblast and CAM Dre Crypt PRO

Wed Mar 14 11:38:21 CET 2012

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.
