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.
