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>

Digital TV Audio Device

#######################
|

|
||
The Digital TV audio device controls the MPEG2 audio decoder of the Digital
|
||
TV hardware. It can be accessed through ``/dev/dvb/adapter?/audio?``. Data
|
||
types and and ioctl definitions can be accessed by including
|
||
``linux/dvb/audio.h`` in your application.
|
||
|
||
Please note that some Digital TV cards don’t have their own MPEG decoder, which
|
||
results in the omission of the audio and video device.
|
||
|
||
These ioctls were also used by V4L2 to control MPEG decoders implemented
|
||
in V4L2. The use of these ioctls for that purpose has been made obsolete
|
||
and proper V4L2 ioctls or controls have been created to replace that
|
||
functionality.
