[media] DocBook/dvbproperty.xml: Remove DTV_MODULATION from ISDB-T

2012-01-17T12:00:41+00:00

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.

[media] DocBook/dvbproperty.xml: Fix ISDB-T delivery system parameters

2012-01-17T11:49:28+00:00

The ISDB-T differs on its way to implement the hierarchical
transmissions: instead of using a low-priority/high-priority
FEC codes, it does that by using different layers, each layer
with their groups of segments. So, those parameters don't make sense
for ISDB-T.

[media] DocBook/dvbproperty.xml: Fix the units for DTV_FREQUENCY

2012-01-17T11:45:48+00:00

The units for DTV_FREQUENCY are kHz for satellital delivery systems
(DVB-S/DVB-S2/DVB-TURBO/ISDB-S). Fix it at the API spec.

Mark info.type as deprecated inside the header, recommending
the usage of DTV_ENUM_DELSYS DVBv5 command instead.

[media] Update documentation to reflect DVB-C Annex A/C support

2011-12-20T13:50:08+00:00

Instead of using the same delivery system for both Annex A and
Annex C, split them into two separate ones. This helps to support
devices that only support Annex A.

[media] dvb: Allow select between DVB-C Annex A and Annex C

2011-11-11T14:46:23+00:00

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.

2011-09-03T21:07:21+00:00

- Move voltage and tone to DVB-S.
- Add turbo code.
- In DVB-S2 and turbo code sections, refer to DVB-S, as both
  are extensions to DVB-S.
