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>

Description
|
||
-----------
|
||
|
||
This ioctl call asks the Audio Device to bypass the Audio decoder and
|
||
forward the stream without decoding. This mode shall be used if streams
|
||
that can’t be handled by the Digial TV system shall be decoded. Dolby
|
||
DigitalTM streams are automatically forwarded by the Digital TV subsystem if
|
||
the hardware can handle it.
|
||
|
||
|
||
Return Value
|
||
------------
|
||
|
||
On success 0 is returned, on error -1 and the ``errno`` variable is set
|
||
appropriately. The generic error codes are described at the
|
||
:ref:`Generic Error Codes <gen-errors>` chapter.
