Put a .dvbrc file containing the DVB channels (satellite or digital terrestial TV channels) you want to stream in your home directory (some are provided in the libdvb tarball for the satellite channels) .
Run VLS with the following command line :
% vls -vv -d udp:192.168.0.42 dvb:"EUROSPORT" --ttl 12
"EUROSPORT" is the channel you want to stream as written in your ~/.dvbrc file ,
192.168.0.42 is either :
the IP address of the machine you want to unicast to ;
or the DNS name the machine you want to unicast to ;
or a multicast IP address .
12 is the value of the TTL (Time To Live) of your IP packets (which means that the stream will be able to cross 11 routers) .
