list, and cannot be shared by another list. The only exception to this rule is a video disk with
multiple streams. Each stream of a video disk can be assigned to a different list, thereby

assigned to a media list, and the playout stream assigned to the play list.
Configuring a Protect Device
A protect device (also known as an air protect device) is a duplicate device that runs in
parallel with the air device. Typically a video disk, the protect disk plays out the identical

is broadcast.
The protect device automatically replaces the air device in the event that the air device loses its
connection with the server.
If the operator notices a problem with the air device (such as poor picture quality) and wishes
to manually switch to the protect device, this can be done by using Harris Automation’s
Air
Client . See the Air Client User’s Guide for details on how to manually switch to the protect
device.
