In fact it is quite easy to do it. First, just make your app, that will read the data from the dvb cards, and then do the following: - packetize the data into 7 ts-packets (7*188=1316): the reason for this is to fit your packet into one MTU (the most usual size for MTU is 1500. This is very good in case packets are dropped on the net - after that, you may add a RTP header (12 bytes). This is optional, but may help you in the future in case you want to implement FEC or to track network congestions. - send the obtained packets on the net (i strongly suggest you to multicast if you use multicast-aware switches) - take vlc for windows, and just play it That's it. Of course you if you want more complicated things: FEC, web management, automatic playlist... you will have to spend more time on that. Good luck! Aurelian -------- Aurelian Pop ONDÉMS Oy P.O.
