The CODI is a character generator device that accepts the EAS processed
data and provides Foreground video and key signals for insertion to the
station program signal chain using its internal video keyer or as a key and
fill source for a master control switcher such as Maestro. The audio cap-

as part of the message display. The EAS Encoder and CODI device coordi-
nate playback to insure that the video display and audio message,
including alert tones, are played simultaneously.
