A quite interesting and well-designed PCI interface chipset designed by B2C2 Inc.. Contains flexible a MPEG2 Transport Stream interface with hardware PID filters, but is still able to deliver the complete Transport Stream. As far we know the chipset contains a Smartcard interface and a CSA Descrambler. Has some Quirks in the i2c Protocol Interface, the PCI bridge driver thus needs to know which clients are allowed on the bus to avoid lockups.

The Linux driver works quite good and has no known drawbacks. Smartcard Interface and CSA Descrambler Support are missing.

The B2C2 FlexCop/FlexCop2 family is e.g. used in the Technisat Skystar2 and the Technisat Airstar 2 DVB Cards.
