Hardware supported by the linuxtv.org DVB drivers
=================================================

  Generally, the DVB hardware manufacturers frequently change the
  frontends (i.e. tuner / demodulator units) used, usually without
  changing the product name, revision number or specs. Some cards
  are also available in versions with different frontends for
  DVB-S/DVB-C/DVB-T. Thus the frontend drivers are listed seperately.

  Note 1: There is no guarantee that every frontend driver works
  out of the box with every card, because of different wiring.

  Note 2: The demodulator chips can be used with a variety of
  tuner/PLL chips, and not all combinations are supported. Often
  the demodulator and tuner/PLL chip are inside a metal box for
  shielding, and the whole metal box has its own part number.


o Frontends drivers:
  - dvb_dummy_fe: for testing...
  DVB-S:
   - ves1x93            : Alps BSRV2 (ves1893 demodulator) and dbox2 (ves1993)
   - cx24110            : Conexant HM1221/HM1811 (cx24110 or cx24106 demod, cx24108 PLL)
   - grundig_29504-491  : Grundig 29504-491 (Philips TDA8083 demodulator), tsa5522 PLL
   - mt312              : Zarlink mt312 or Mitel vp310 demodulator, sl1935 or tsa5059 PLL
   - stv0299            : Alps BSRU6 (tsa5059 PLL), LG TDQB-S00x (tsa5059 PLL),
                          LG TDQF-S001F (sl1935 PLL), Philips SU1278 (tua6100 PLL),
                          Philips SU1278SH (tsa5059 PLL), Samsung TBMU24112IMB

l' informazione utile sarebbe:

"
Technisat Sky2Pc Rev. 2.6 frontend stv0299, Rev. 2.3 frontend mt312
"

come si desume dal documento che ho trovato in rete (www.lpmagazine.org,
autore Piotr Wolny  autorzy a lpmagazine.org):

equipo frontend.

En caso de mi SkyStar2 Rev. 2.6 se aplicaron los sistemas respectivamente B2C2 Sky2Pc y stv0299, con lo cual era suficiente cargar los módulos b2c2_flexcop y stv0299.
La versión más antigua de SkyStar2, es decir, Rev. 2.3 funciona en módulos b2c2_ flexcop y mt312.
En caso de otras tarjetas podemos buscar información sobre los sistemas en su documentación técnica o bien en la página http://www.linuxtv.org/wiki/ index.php/Supported_DVB_cards.
Incluso puede pasar que el módulo de nuestra tarjeta se encuentre en el directorio /drivers/media/ video/. Cuando ya sabemos qué módulos necesitamos, damos el comando lsmod o bien cat /proc/modules, compro
bando que se encuentran en el listado mostrado por uno de estos comandos.
Cuando estos falten, desde la cuenta de root damos el comando
