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 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. |
