[linux-dvb] Re: Receiving high resolution weather satellite pictures from HotBird

[hugo.van.ruyskensvelde@easynet.be]

Hi,

The format of the pictures is described in PDF files that are freely available 
from www.eumetsat.de. Those pictures can be encrypted, (but not for the 
moment ) and compressed.  The files are written to directories on the hard 
disk. The organisation of the data stream itself is ( I think ) a format of 
tq-Tellicast. I understand that there is client software available for Linux 
, but it is not open source :( . After jan. 2004 the decryption is done via a 
USB dongle and cost about 20 £.
