+# LIBDDDVB
+The libdddvb provides a userspace library to simplify tuning and
+CI use. It detects DVB cards and their capabilities and selects
+free frontends depending on a given delivery system.
+
+
+In order to install the libdddvb library you need the dvben50221.
+
+On an Ubuntu and other Debian based system you can install it like this:
+
+`sudo apt-get install dvb-apps` 
+
+After that you can build the libdddvb:
+
+`git clone https://github.com/DigitalDevices/dddvb.git` 
+
+`cd dddvb/lib/; make` 
+
+`sudo make install` 
+
+If your distribution does not include a dvb-apps package, you can follow the 
+instructions at 
+
+https://www.linuxtv.org/wiki/index.php/LinuxTV_dvb-apps
+
+on how to build it yourself.
+
+
+# DDZAP
+
+You can now use the example program ddzap to see how the library
+is used or to test your cards.
+
+A typical usage example would be the tuning of a
+sattelite channel with a given LNB configuration.
+ 
+`ddzap -d S2 -p h -f 11494000  -s 22000000  -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 -`
