| 9 | Once :ref:`FE_SET_PROPERTY <FE_GET_PROPERTY>` is called, the |
| 10 | frontend will run a kernel thread that will periodically check for the |
| 11 | tuner lock status and provide statistics about the quality of the |
| 12 | signal. |
| 13 | |
| 14 | The information about the frontend tuner locking status can be queried |
| Mauro Carvalho Chehab | 7347081 | 2016-07-01 13:58:44 -0300 | [diff] [blame] | 15 | using :ref:`FE_READ_STATUS`. |
| Markus Heiser | 5377d91 | 2016-06-30 15:18:56 +0200 | [diff] [blame] | 16 | |
| 17 | Signal statistics are provided via |
| Mauro Carvalho Chehab | 7347081 | 2016-07-01 13:58:44 -0300 | [diff] [blame] | 18 | :ref:`FE_GET_PROPERTY`. Please note that several |
| Markus Heiser | 5377d91 | 2016-06-30 15:18:56 +0200 | [diff] [blame] | 19 | statistics require the demodulator to be fully locked (e. g. with |
| 20 | FE_HAS_LOCK bit set). See |
| 21 | :ref:`Frontend statistics indicators <frontend-stat-properties>` for |
| 22 | more details. |
