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>

Querying frontend status and statistics
|
|
***************************************
|
|
|
|
Once :ref:`FE_SET_PROPERTY <FE_GET_PROPERTY>` is called, the
|
|
frontend will run a kernel thread that will periodically check for the
|
|
tuner lock status and provide statistics about the quality of the
|
|
signal.
|
|
|
|
The information about the frontend tuner locking status can be queried
|
|
using :ref:`FE_READ_STATUS`.
|
|
|
|
Signal statistics are provided via
|
|
:ref:`FE_GET_PROPERTY`. Please note that several
|
|
statistics require the demodulator to be fully locked (e. g. with
|
|
FE_HAS_LOCK bit set). See
|
|
:ref:`Frontend statistics indicators <frontend-stat-properties>` for
|
|
more details.
