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 is for Digital TV devices only. To control a V4L2 decoder use the
|
|
V4L2 :ref:`VIDIOC_DECODER_CMD` instead.
|
|
|
|
This ioctl call asks the Video Device to stop playing the current
|
|
stream. Depending on the input parameter, the screen can be blanked out
|
|
or displaying the last decoded frame.
|
|
|
|
|
|
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.
