+/** \brief Helperclass for configuration and controlling DVB devices.
+
+ The DVB API provides two methods for tuning. The first method is
+ synchronous, which means e.g. "tuneTo_sync" will return when the tuning operation on the card
+ succeed, no matter how long it takes. The second (preferred) method is to tune asynchronous.
+ The call "tuneTo" will return immediately and (if a callback was set) call the callback when
+ the tuning operation succeeds. <br>
+
+ Note that you may have to take draw backs in using this API. This dues to the implementation
+ of the DVB device driver which you or your kernel choose. It has shown that the completeness
+ of implementations vary from driver to driver. This wrapper provides the full Frontend API which
+ is defined by <a href="http://www.linuxtv.org/docs/dvbapi/DVB_Frontend_API.html">Convergence</a>.
+ You have to find out which parts of these functionality are implemented by your preferred
+ device driver by your own.
