+      When scanning for dvb channels,
+      most applications require an initial set of
+      transponder coordinates (frequencies etc.).
+      These coordinates differ, depending of the
+      receiver's location or on the satellite.
+      The package delivers a collection of transponder
+      tables ready to be used by software like "dvbv5-scan".
+      The package at hand is maintained and used by tvheadend,
+      it is a fork of the original one hosted by linuxtv.org.
