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`.
|
|
|
|
.. note::
|
|
|
|
Most statistics require the demodulator to be fully locked
|
|
(e. g. with :c:type:`FE_HAS_LOCK <fe_status>` bit set). See
|
|
:ref:`Frontend statistics indicators <frontend-stat-properties>` for
|
|
more details.
