Hi

I have a question , there is a device called (inet device) or inet season interface ( ethernet season interface ) , its jub is to :

(( provides your digital receiver its information via your local network or the Internet instead of the local smartcard. This means that you can locate your smartcard somewhere else instead of having it directly in your receiver.))

I wanted to buy this device but the price is too high about 120 euros .

When I saw the pics of this devise it looked very simple , just like an ordinary season interface and simply buildable but I'm sure there must be some ATMEGA or somthing in the other side of the PCB.

So please help me for any sujestion about circuit or anything else ,maybe I could build this device
Below is two pics from this device

Best regards : Alireza
