* [media] DocBook: document DVB DMX_[ADD|REMOVE]_PIDMauro Carvalho Chehab2014-03-04
| | | | | | | | | | | | Those ioctls were added back in 2009, at changeset 1cb662a3144 but were never documented. Fortunately, the original commit is good enough to serve as the basis for documenting it. Also, the support for it is done by dmxdev implementation. So, add a proper documentation for it, based on the description of the original changeset. Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>

* [media] dvb: Add DVBv5 statistics propertiesMauro Carvalho Chehab2013-01-23
| | | | | | | | | | | | | | | | | | The DVBv3 statistics parameters are limited on several ways: - It doesn't provide any way to indicate the used measure, so userspace need to guess how to calculate/use it; - Only a limited set of stats are supported; - Can't be called in a way to require them to be filled all at once (atomic reads from the hardware), with may cause troubles on interpreting them on userspace; - On some OFDM delivery systems, the carriers can be independently modulated, having different properties. Currently, there's no way to report per-layer stats. To address the above issues, adding a new DVBv5-based stats API. While here, correct inner code nomenclature on a few places.

* [media] DocBook/dvbproperty.xml: Remove DTV_MODULATION from ISDB-TMauro Carvalho Chehab2012-01-17
| | | | | | | | | On ISDB-T, each layer can have its own independent modulation, applied to the carriers that belong to the segments associated with them. So, there's no sense to define a global modulation parameter. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

* [media] dvb: Allow select between DVB-C Annex A and Annex CMauro Carvalho Chehab2011-11-11
| | | | | | | | | | | | | DVB-C, as defined by ITU-T J.83 has 3 annexes. The differences between Annex A and Annex C is that Annex C uses a subset of the modulation types, and uses a different rolloff factor. A different rolloff means that the bandwidth required is slicely different, and may affect the saw filter configuration at the tuners. Also, some demods have different configurations, depending on using Annex A or Annex C. So, allow userspace to specify it, by changing the rolloff factor.
