The Digital TV CA device controls the conditional access hardware. It can be accessed through /dev/dvb/adapter?/ca?. Data types and ioctl definitions can be accessed by including linux/dvb/ca.h in your application.

Note

There are three ioctls at this API that aren’t documented: CA_GET_MSG, CA_SEND_MSG and CA_SET_DESCR. Documentation for them are welcome.
