 Description:
 
 DVB Frontend Status Monitor is a plugin that displays some signal information
 parameters of the current tuned channel on OSD. You can zap through all your
 channels and the plugin should be monitoring always the right frontend. The
-transponder information is also available in advanced display mode. User can
-switch between simple and advanced display modes by pressing 'OK' key.
+transponder and stream information are also available in advanced display modes.
 
-The plugin is based on a neat console frontend status monitor application called 
-'femon' by Johannes Stezenbach <js@convergence.de> (see DVB-apps/szap/femon.c
-for further information). The other parts of plugin code are borrowed from the 
-excellent 'OSD Picture-In-Picture' plugin by Sascha Volkenandt <sascha@akv-soft.de>
-and Andreas Regel <andreas.regel@powarman.de>. The bitrate calculation algorithm
-originates from the 'dvbstream' application by Dave Chapman <dave@dchapman.com>.

+Notes:
 
-- The current version is a kind of Proof In Concept to replace the old 'tech
-  patch', and it's now eating many unnecessary cpu clock cycles - this will be
-  fixed later...
 - The plugin supports only those DVB cards with _one_ frontend (do any cards
   with multiple frontends even exist?), because I haven't yet figured howto do
   it without patching the VDR core.
 - Sometimes (read always) ttxtsubs plugin messes up the OSD - user should disable
   ttxtsubs, but closing and reopening the femon plugin might help temporarily as
   well. Btw., this same thing happens with OSDTeletext plugin too :)
-- The plugin GUI is designed for _small fonts_, so stable vdr-1.2.6 users should
-  consider a small font patch (e.g. ElchiAIO4a) to maximize the visual effect :)
+- Disable the stream analyze to speed up heavy zapping sessions.
+- The signal strength and signal-to-noise ratio values are comparable only
+  between the same brand/model frontends. Due to the lack of proper frontend
+  specifications those values cannot be calculated into any real units.
+- Shrinked OSD is available for NTSC users: make NTSC_SYSTEM=1
+- The device switching feature is still non-functional.
