     12DVB-C delivery system
     13=====================
     14
     15The DVB-C Annex-A is the widely used cable standard. Transmission uses
     16QAM modulation.
     17
     18The DVB-C Annex-C is optimized for 6MHz, and is used in Japan. It
     19supports a subset of the Annex A modulation types, and a roll-off of
     200.13, instead of 0.15
     21
     22The following parameters are valid for DVB-C Annex A/C:
     23
     24-  :ref:`DTV_API_VERSION <DTV-API-VERSION>`
     25
     26-  :ref:`DTV_DELIVERY_SYSTEM <DTV-DELIVERY-SYSTEM>`

     44In addition, the :ref:`DTV QoS statistics <frontend-stat-properties>`
     45are also valid.
