Properties used on satellite delivery systems

.. _dvbs-params:

DVB-S delivery system
=====================

The following parameters are valid for DVB-S:

-  :ref:`DTV_API_VERSION <DTV-API-VERSION>`

-  :ref:`DTV_DELIVERY_SYSTEM <DTV-DELIVERY-SYSTEM>`

-  :ref:`DTV_TUNE <DTV-TUNE>`

-  :ref:`DTV_CLEAR <DTV-CLEAR>`

-  :ref:`DTV_FREQUENCY <DTV-FREQUENCY>`

-  :ref:`DTV_INVERSION <DTV-INVERSION>`

-  :ref:`DTV_SYMBOL_RATE <DTV-SYMBOL-RATE>`

-  :ref:`DTV_INNER_FEC <DTV-INNER-FEC>`

-  :ref:`DTV_VOLTAGE <DTV-VOLTAGE>`

-  :ref:`DTV_TONE <DTV-TONE>`

In addition, the :ref:`DTV QoS statistics <frontend-stat-properties>`
are also valid.

Future implementations might add those two missing parameters:

-  :ref:`DTV_DISEQC_MASTER <DTV-DISEQC-MASTER>`

-  :ref:`DTV_DISEQC_SLAVE_REPLY <DTV-DISEQC-SLAVE-REPLY>`


.. _dvbs2-params:

DVB-S2 delivery system
======================

In addition to all parameters valid for DVB-S, DVB-S2 supports the
following parameters:

-  :ref:`DTV_MODULATION <DTV-MODULATION>`

-  :ref:`DTV_PILOT <DTV-PILOT>`

-  :ref:`DTV_ROLLOFF <DTV-ROLLOFF>`

-  :ref:`DTV_STREAM_ID <DTV-STREAM-ID>`

-  :ref:`DTV_SCRAMBLING_SEQUENCE_INDEX <DTV-SCRAMBLING-SEQUENCE-INDEX>`

In addition, the :ref:`DTV QoS statistics <frontend-stat-properties>`
are also valid.

Annotation

Atlas domain: Support Tooling And Documentation / Documentation.
Implementation status: atlas-only.

Implementation Notes

This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
