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)
