Apart from the frequency and signal level differences, DVB-T is a 6-8MHz
wide signal with COFDM modulation, using 2k to 8k subcarriers, while DVB-S
is a single carrier, 6..36MHz wide signal, usually QPSK or 8PSK. You cannot
use a downconverter and a DVB-T receiver to tune into a DVB-S channel.
However, the digital bitstream carried by both is the same - so if you have
software analyzers and audio/video players for DVB-T they will work for
