[linux-dvb] Measuring signal strench on TT S2-3200

[" SKOČDOPOLE Tomáš" <hoppik@centrum.cz>]

Hello,

For quick test I used getstream utility. Later I am planning to use vdr with some plugins for streaming. 

I have parabola directed to 23.5E (Astra 3A/1E). I tested two FTA programs Ocko and CT24. On second computer there was VLC running. I think parabola is directed correctly, because I have borrowed desktop receiver and there was no problem with these programs.

I tried latest drivers from Igor M. Liplianin but I have the same problems with multiproto drivers.

When I was streaming Ocko, on second computer there was good screen, but sometimes (aprox once per 30 seconds) was shortly breaking.

When I was streaming CT24, it was running only for max 10 seconds and then getstream utility stopped sending stream packets.

There is debug output from getstream utility:

        sap {

                playgroup "testovaci sat";
                ttl 5;
        };
    };
};
