 - Fixed scaling subtitles in case the primary device's GetVideoSize() function doesn't
   return actual values (thanks to Luca Olivetti).
 - The DiSEqC codes are now copied in the call to cDiseqc::Execute().
+- VDR now supports "Satellite Channel Routing" (SCR) (based on the "unicable" patch
+  from Lars Hanisch). Since "Unicable" is a registered trademark and stands for only
+  one of many implementations of SCR, the following changes have been made compared
+  to the patch, which need to be taken into account by people who have set up their
+  system using the patch:
+  - The 'U' parameter in the diseqc.conf file has been changed to 'S' ("Scr").
+  - The configuration file name has been changed from "unicable.conf" to "scr.conf".

INSTALL

@@ -386,6 +386,12 @@ accessed using DiSEqC, you have to go to the "Setup" menu and set the "DiSEqC"
 parameter to "on". You also need to set up the file 'diseqc.conf' to properly
 access your DiSEqC equipment (see man vdr(5) for details).
 
+A special form of DiSEqC is used to connect several receivers to one signal
+source using only a single cable. This method, known as "Satellite Channel Routing"
+according to EN50494 (aka "Unicable(TM)", "OLT(TM)", "SatCR", "Single Cable
+Distribution", "Channel Stacking System" or "Single Cable Interface") uses
+the file "scr.conf" to specify which SCR channels use which user band frequency.
