The Media Cache Service
•
Max Transfer Rate (MB/s) - allows users to set the maximum caching speed, up to
1024MB/s (or 8.192 Gbit/sec). This option defaults to 0 MB/s, which means the speed is
uncapped.
•
Block Size (MB) - allows users to control the size of the data blocks that are written to
disk. The default is 8MB. Increasing this value can reduce the amount of throttling that is
required during caching and improve the overall performance.
Media Watcher
In the Media Watcher box, you select the Media Watcher that is to copy files from external
search folders when they are required for playout. Depending on the search-folder
configuration, the copy destination may be either the Output Server cache or a Media Store
managed by the Media Watcher.
Search-domains panel
Through the search-domains panel, you may set up a Media Cache Service to use its own
search domains list instead of the central list that you configure in the Media Watcher.
The panel is similar to the one under the Domains tab of the Media Watcher user interface. It
has an extra button:
You use this button to switch the service between using the local configuration and the central
one.
Note:
•
If you set up the Media Cache Service to use a local domain search list, you must set
up TX Play on the same machine to use an identical list.
Cache channel in a Schedule Grid
On an iTX Desktop layout, you can connect a Schedule Grid to a cache channel and view
detailed information (including % cached) on cache contents:
When you move your mouse pointer over the entry for any media file, a tooltip appears
(provided tooltips are switched on) showing the recent history of checking and caching
operations for the file.
