system.  This is called “Compel-over-Internet”.  Along with this capability, the i6420 may also 
poll for and then pull in it’s local spot files over the same internet connections.  This is called 
“Internet File Delivery”.  This allows the i6420 to easily implement a premium radio network 
feature called “Automation Mode”, to be discussed. 
Compel commands, either directly addressed, or addressed as groups, or “indirectly 
addressed” based on current unit settings, are one method of controlling iPump6420 Audio 
Servers.  Because of timing-delay functions built into Compel, the network operator can 
accurately overlay network “avails” with local spots.  In addition to real-time Compel 
commands, the network operator can exploit the network-wide time synchronization of all 
Wegener edge receivers when being fed from a single Compel control system.  Just as events 
may be scheduled in the Compel control system, those same schedules may also be loaded to the 
remote field iPump6420s.  These schedules can create a model for iPump 6420 automatic 
behavior, guaranteeing that critical commands are executed on target i6420s precisely at 
expected times.

Premium Features 
Automation Mode 
In Automation Mode, the i6420 is totally removed from the need for a satellite downlink 
connection.  In this mode, the i6420 functions as a “radio station in a box”.  All its content, from 
local spots to the music or talk-format material, is downloaded to the unit as audio files.  Daily 
schedule files, which give traffic-system instructions to the unit, are regularly downloaded to the 
unit.  The unit is directed to an NTP time source through its LAN IP connection.   With the time 
reference and the traffic schedule, the unit then autonomously plays it’s files, delivers closures 
and sends RBDS messages to the local radio network affiliate. 
ShowShifting 
Many syndicated radio shows originate at a specific time in the broadcast day.  For a radio-
network to resell that show, it often has to record the original feed and then re-broadcast over 
satellite later at times convenient for the subscribing affiliates.  This is a waste of satellite 
bandwidth when the iPump6420’s ShowShifting feature is purchased and made available.  This 
feature allows the central radio network manager, or a local user, to schedule local recording of 
the original show episodes, then subsequent planned playback times.  These recordings are, 
unlike a “Tivo”, include more than the streamed audio feed, but also include a capture of the 
timestamped track of associated Compel commands that went out with the original program 
episode:  Commands for local spot plays, RBDS messages, and for local relay closure outputs.  
This whole effort is done so seamlessly that, at playback, the local affiliate cannot distinguish 
between the original show episode broadcast and the ShowShifted episode playback.
