# define channels:
# channels are frequency slots to which a stream (mod0, mod1 ...) can be assigned

[channels]
# standard: 0 = generic, 1 = DVB-T 8MHz, 2 = DVB-T 7 MHz, 3 = DVB-T 6 MHz

# this defines 25 channels at 474, 474+8, 474+16, etc. Mhz

frequency = 474.0


[streams]
# number of streams depends on the card hardware
# streams correspond to devices mod0, mod1, ...
# channels are defined above in channels section

# all following streams will be set according to the last set other parameters

# example:
# this would set mod 1 to 474 MHz and mod0 to 482 MHz (474 + 8 MHz)
# both with guard interval 1/32 and 8K FFT
# and mod2 to 490MHz, guard interval 1/16 and 8K FFT
