My DreamBox (a linux-based digital television receiver, which has a smartcard
reader and uses a software CAM for conax decoding) is able to decode multiple
Conax-coded channels simultaneously. There is also an option to set the
DreamBox to have a "card server" process which is available on a port of the
device, which can be telnet'ed to by this and other boxes needing to decode
channels (I've seen this done with a satellite system). As a test I've had the
DreamBox record five channels simultaneously from two different bouquets (mine
has two cable tuners, so this is the limit for bouquets).
So, at least with Conax cards, this is doable. It'd be nice to be able to use
a separate "pluggable" decoder / card reader with vdr, so that my vdr could
ask for the decoding card from my DreamBox, or vice versa?
Have software cams or card readers been ported to vdr?
