The Media Cache Service
Setting up a system for multi-domain caching
There are a number of ways in which you can set up a system to handle the copying of media
files between two iTX domains. The required procedure depends on whether or not you want
iTX to register files by creating media items for them in the System Database of the new
domain.
In registering a file, iTX creates either a whole new media item or one that includes information
(e.g. in- and out-points) from the corresponding media item in the original domain. The copying
of information from another media item requires the External Multi-domain plug-in.
Set up a system to copy files without registering them in the new domain
Use this procedure for the copying of files that you want iTX to hold only temporarily in the
new domain. The Media Cache Service removes such files in its cache management operations
when they are no longer needed for playout.
1.
Do the following to configure the Media Watcher in the new domain.
• Add the file store in the remote domain as a Search folder.
• Ensure Copy media to central store is not selected for this folder.
• Select Search for Omnibus '_OMN' files.
2. Ensure the user account you use to run the Output Server machine has access rights to the
Search folder.
3. Set the remote-domain search order for both TXPlay and the Media Cache Service on the
Channel Configuration pop-up layout.
