Configuring a Media Watcher
Configuring a Media Watcher
All iTX systems include a Media Watcher. This usually runs on an iTX Media Store (if that
machine allows it to).
More complex systems may have more than one Media Watcher. For example, if you keep the
media files for different groups of channels on different Media Stores, you may allocate a
separate Media Watcher to each Media Store.
For each Media Watcher, the configuration includes details of the paths of an Inbox folder and
a Media folder on the iTX Media Store. The Media Watcher monitors the Inbox folder for files
being added to the iTX system. It moves the files to the Media folder after registering them:
In some systems, you may install the Media Watcher on an iTX machine that is not an iTX
Media Store. For instance, when using a NAS (network-attached storage) system to hold the
media files, you may run the Media Watcher on the Database Server machine. You should then
place the Inbox and Media folders inside the same, shared folder on the iTX Media Store; this
ensures the Media Watcher transfers files between the Inbox and the Media folder most
efficiently.
You specify the Inbox and Media folder paths when configuring a Media Watcher after
installing it. Through other configuration settings, you may:
• Specify additional iTX Media Stores for media storage and playout.
• Set properties for iTX Media Stores, including a high-water mark for disk-space usage.
• Specify external file stores so that the Media Watcher has access to their media files.
In doing this, you may set up the Media Watcher to copy required files to the Inbox, to
register them in the iTX system before moving them to the Media folder. External file
stores may be folders on external storage devices; or file stores in other iTX domains.
The Media Watcher does not manage external file stores.
• Adjust the rate at which the Media Watcher copies files from an external file store to
an iTX Media Store.
• Specify a limit (high-water mark) for disk-space usage by the Inbox; the Media
Watcher stops copying files to the Inbox from external file stores when the limit is
reached.
• Start or stop the Media Watcher monitoring the Inbox (and processing any files that
appear in it).
• Set a registration delay, to prevent the Media Watcher registering files too early. You
may need to do this to ensure the Media Watcher only registers any file copied from
an FTP server when the complete file is in the Inbox.
• Request the Media Watcher to automatically create, on the iTX Media Store, browse
copies of new video clips after they are registered. A browse copy is a low bit-rate
Windows Media 9 file.
• Request the Media Watcher to automatically create, on the iTX Media Store,
keyframes from new video clips after they are registered.
