## Detailed Description

Structure containing the satellite delivery system descriptor.

Parameters

  type | descriptor tag
  length | descriptor length
  next | pointer to struct dvb_desc
  frequency | frequency in kHz
  orbit | orbital position in degrees (multiplied by 10)
  west_east | west east flag. 0 = west, 1 = east
  polarization | polarization. 0 = horizontal, 1 = vertical, 2 = left, 3 = right.
  roll_off | roll off alpha factor. 0 = 0.35, 1 = 0.25, 2 = 0.20, 3 = reserved.
  modulation_system | modulation system. 0 = DVB-S, 1 = DVB-S2.
  modulation_type | modulation type. 0 = auto, 1 = QPSK, 2 = 8PSK, 3 = 16-QAM (only for DVB-S2).
  symbol_rate | symbol rate in Kbauds.
  fec | inner FEC (convolutional code)
