As tcp need acks from the client, with http I have :
dvbbox -> wifi master -> client -> wifi master -> dvbbox
        data           data      ack+http            ack+http

With udp I hope to only have
dvbbox -> wifi master -> client

Because on wifi only one host could send packet at a given time (not 
full-duplex), with udp I save the time need for "client -> wifi master 
-> dvbbox". With that time I could send more data. Also I avoid some 
collision, and could send more data.

That's what I wanted to try next.Is there a way to link them with vdr ?

I could also make an ad-hoc connection between dvbbox and client and 
have 2 more bandwidth, but both will lose internet connection :(
