Using MOS Redirection to transfer media between
Xmedia Servers
Using a MOS Protocol based technique called MOS Redirection, Xmedia Servers work
with the ENPS Newsroom Computer System (NCS) to transfer stories and their associated
media between Xmedia Servers within a single newsroom, or between multiple newsrooms
and Xmedia Servers in different locations.
The following sections provide more information about how the Xmedia Server works with
ENPS to transfer media between servers:

Prerequisites for using MOS Redirection
It is a prerequisite that your ENPS Newsroom Computer System (NCS) be properly
configured for MOS Redirection. We strongly recommend that you consult the AP ENPS
Integration Guide for more information about MOS Redirection and instructions for setting
up MOS Redirection within ENPS.
To use MOS Redirection with the Xmedia Servers, stories and their items must be created
with Vertigo Suite’s Xnews v.4.9 or greater. The MOS items that are created in Xnews v.4.9
will contain the objPath MOS protocol field that allows the local Xmedia Server to resolve
the IP of the remote Xmedia Server from which the underlying media of stories/items are
obtained.

At least one item in the story must have the objPath field for MOS Redirection to function
properly. If a MOS item was created in a version previous to v.4.9, reopening an item in
Xnews and saving the item inserts the required objPath.
Overview of the MOS Redirection workflow
When a story is dragged and dropped from foreign rundown to a local rundown inside
ENPS, the Xmedia Server’s MOS Server recognizes this event by the fact that the MOS ID
of the items do not match the Xmedia Server’s MOS ID. As a result, the redirection process
is triggered.
During the MOS redirection of an item, the Xmedia Server only tries to fetch assets that do
not already exist locally. Note that there is no checking to see if the asset on the remote
server is newer than the local asset. If the asset is already on the local server, the Xmedia
