how to install nonfree firmware for dvb usb interface dtv-2go on Open-Suse (12.2)

Hello,
I would like to use my usb dvb interface (dtv-2go) with freshly installed Open-Suse 12.2 distro.
I think I have to install something like firmware-nonfree or linux-firmware-nonfree or firmware-linux-nonfree but I do not know how.
What I have to do for having that on the system?
Thanks in advance

firmware-nonfree or linux-firmware-nonfree

'nonfree' means that the software is bound to a license or copyright restrictions that impose limitations to your use and disposition: in short, it is not as free as the Gnu software to you, and that someday somewhere you not knowing what the license provisions over that is all about you can become illegal or something unlawful.

"FREE" in the world of Free and Open Source Software is all about "FREEDOM" and not necessarily like a "free beer" (buy me some if you have money ) Please read about it here.

HOpe that helps.

Thanks but I already know about free software.
Now I need to install that well-known package that is available also for other distros to be able to see dvb TV programs with dtv-2go usb interface. If there is another way I will be glad to read about it.
