-DVB Frontend API
-################
-The DVB frontend API was designed to support three types of delivery
-systems:
-
-- Terrestrial systems: DVB-T, DVB-T2, ATSC, ATSC M/H, ISDB-T, DVB-H,
- DTMB, CMMB
-
-- Cable systems: DVB-C Annex A/C, ClearQAM (DVB-C Annex B), ISDB-C
-
-- Satellite systems: DVB-S, DVB-S2, DVB Turbo, ISDB-S, DSS
-
-The DVB frontend controls several sub-devices including:
-
-- Tuner
-
-- Digital TV demodulator
-
-- Low noise amplifier (LNA)
-
-- Satellite Equipment Control (SEC) hardware (only for Satellite).
-
-The frontend can be accessed through ``/dev/dvb/adapter?/frontend?``.
-Data types and ioctl definitions can be accessed by including
-``linux/dvb/frontend.h`` in your application.
-
-.. note::
-
- Transmission via the internet (DVB-IP) is not yet handled by this
- API but a future extension is possible.
-
-On Satellite systems, the API support for the Satellite Equipment
-Control (SEC) allows to power control and to send/receive signals to
-control the antenna subsystem, selecting the polarization and choosing
-the Intermediate Frequency IF) of the Low Noise Block Converter Feed
-Horn (LNBf). It supports the DiSEqC and V-SEC protocols. The DiSEqC
-(digital SEC) specification is available at
-`Eutelsat <http://www.eutelsat.com/satellites/4_5_5.html>`__.
