The name of the subsystem is "media", and not "linux_tv". Also, as we plan to add other stuff there in the future, let's rename also the media uAPI book to media_uapi, to make it clearer. No functional changes. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>

DVB Audio Device
|
||
################
|
||
The DVB audio device controls the MPEG2 audio decoder of the DVB
|
||
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 DVB 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.
