| 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 FE_HAS_LOCK bit set). See |
| :ref:`Frontend statistics indicators <frontend-stat-properties>` for |
| more details. |
