The usage of the term "DVB" at the dvb API docs is confusing, as, right now, it can refer to either the European digital TV standard or to the subsystem. So, prefer calling it as "Digital TV" on most places, to avoid ambiguity. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>

|
The Digital TV CA device controls the conditional access hardware. It
|
|
can be accessed through ``/dev/dvb/adapter?/ca?``. Data types and 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:
|
|
:ref:`CA_GET_MSG`, :ref:`CA_SEND_MSG` and :ref:`CA_SET_DESCR`.
|
|
Documentation for them are welcome.
