+# LIBDDDVB
+
+In order to install the libdddvb library 
+
+https://github.com/DigitalDevices/dddvb
+
+you need dvben50221.
+
+
+On an Ubuntu system this would look like this:
+
+`sudo apt-get install dvb-apps` 
+
+`git clone https://github.com/DigitalDevices/internal_dddvb.git` 
+
+`cd dddvb/lib/; make` 
+
+`sudo make install` 
+
+# DDZAP
+
+You can now use the example program ddzap for tuning.
+
+A typical usage example call would be:
+ 
+
+`ddzap -d S2 -p v -f 10847000  -s 23000000  -c ~/dddvb/lib/config/`
+
+where you would use the example configuration file for a unicable LNB
+given in the sources. If you leave out the `-c` option a standard universal
+LNB is assumed to be connected.
+
+Additionally you can use ddzap to open the /dev/dvb/adaptorX/dvrY device
+that corresponds to the tuner that was automatically selected by the library
+and pipe it to a media player, e.g.
+
+
+`ddzap -d S2 -p h -f 11494000  -s 22000000  -c /home/dmocm/ddzapconf/  -o|vlc -` 
+
