| 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. |
