I think that dvblast is much closer to accomplish what you want, rather
than tsdecrypt.

It already knows about communicating with CIs, adding CAPMTs, monitoring
their status, working with the menus, etc. etc.

DVBlast can also currently grab the input from udp rather than DVB, what's
left to be done is that the stream should be sent to the hardware.
