Dvblast protect stream it's possibile?

[cartelet]

Sorry maybe not the correct section, but I could not find any forums that talk about dvblast ...

I have a complete IPTV videolan, let me explain:

server is installed dvblast ago streaming multicast UDP or RTP

client is VLC

all connected in LAN


My question is, it's possible to protect the stream from the server to the client with some kind of encryption? (I did not find much about it)
