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)
