- 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.
- .. _dvbc-annex-b-params:
- DVB-C Annex B delivery system
- =============================
- The DVB-C Annex-B is only used on a few Countries like the United
- States.
- The following parameters are valid for DVB-C Annex B:
- - :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_LNA <DTV-LNA>`
- In addition, the :ref:`DTV QoS statistics <frontend-stat-properties>`
- are also valid.
