The DVB part should not be too hard -- after looking on the screen shots 
I suppose they transmit the data using multicast TCP over DVB, so you 
only have to set up a network connection using the dvbnet utility and 
then process the received data...

Do you know what data format they use? Their presentation is talking 
about JPEG and a wavelet compression scheme but is not clear to me. 
Probably they also have some side information describing positional 
information of the scanning satellite...
