      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".
