Configuring channels
Media Keep List – for playout channels
The Media Cache Service on an Output Server machine maintains a cache of media files based
on schedule requirements. It deletes these files, when they are no longer needed, to allow new
media files to be cached.
There may be some media files, such as channel logos, that you want the Media Cache Service
to always keep in the cache. The service holds a list of these files and caches them before it
caches other media files. We call the list the Media Keep List.
The list has two parts. One part has details of media files you manually add to the list. The other
part has details of media files iTX automatically adds to the list – these are the ones you specify
in the channel configuration (e.g. an off-air slide).
Both parts of the list are displayed in separate panes under the Media Keep List tab:
• The upper pane shows the manual part of the Media Keep List; i.e. details of the files
you add to the list.
• The lower pane shows the files iTX adds to the list.
You can modify the list in the upper pane by adding or deleting files.
Where you want to use the same list for more than one channel, you can export a copy (of the
manual part of the list) from one channel and import it into another. Exporting creates a Keep
List file in the XML format.
