In order to access the Sky channels VDR needs to know the channel number
under which each channel is stored in the Sky Digibox. These numbers are
used as 'frequency' parameters in the channels.conf definitions of the Sky
channels (see the file 'channels.conf.sky'). Since these numbers are always
less than 1000, they can be easily distinguished from normal satellite
transponder frequencies. The VPID is 160 and the APID is 80 for all Sky
channels. These are just fake PIDs, since the Kfir card always uses these
fixed PIDs. The 'Ca' parameter of the Sky channels is set to 301, which
is defined as "Videoguard, Sky Digital" in VDR's 'ca.conf' file. Again, please
note that VDR doesn't do any decrypting here, this is just to mark these
channels as "conditionally accessible" and have a way of setting the CICAM
value for the Kfir device in VDR's Setup menu.

The Perl script getskyepg.pl extracts the EPG data from these pages
and sends it to VDR via an SVDRP connection. The channel numbers Sky
uses to generate the EPG pages are stored as the 'sid' parameter in
the channels.conf definitions of the Sky channels. You can keep your
EPG data up-to-date by entering a call to getskyepg.pl into your
