The conversion script added some comments at the end. They point to the original DocBook files, with will be removed after the manual fixes. So, they'll be pointing to nowere. So, remove those comments. They'll be forever stored at the Kernel tree. So, if someone wants the references, it is just a matter of looking at the backlog.

DVB-C delivery system
|
|
=====================
|
|
|
|
The DVB-C Annex-A is the widely used cable standard. Transmission uses
|
|
QAM modulation.
|
|
|
|
The DVB-C Annex-C is optimized for 6MHz, and is used in Japan. It
|
|
supports a subset of the Annex A modulation types, and a roll-off of
|
|
0.13, instead of 0.15
|
|
|
|
The following parameters are valid for DVB-C Annex A/C:
|
|
|
|
- :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_MODULATION <DTV-MODULATION>`
|
|
|
|
- :ref:`DTV_INVERSION <DTV-INVERSION>`
|
|
|
|
- :ref:`DTV_SYMBOL_RATE <DTV-SYMBOL-RATE>`
|
|
|
|
- :ref:`DTV_INNER_FEC <DTV-INNER-FEC>`
|
|
|
|
- :ref:`DTV_LNA <DTV-LNA>`
|
|
|
|
In addition, the :ref:`DTV QoS statistics <frontend-stat-properties>`
|
|
are also valid.
