Working with the Media Watcher
Working with the Media Watcher
An iTX system must have a Media Watcher to manage the Media Store. It may have additional
Media Watchers to manage multiple Media Stores.
The Media Watcher performs these tasks:
• It provides the main way of ingesting media files into iTX. To do so, it controls the
copying of existing media files onto a Media Store and registers these files in the
System Database.
• It registers, in the System Database, files that an Encode Server creates in recording
digital video content from a videotape, video server or live feed.
• It registers, in the System Database, media that exists on an external Media Store,
such as a video server.
• It responds to requests from a Media Cache Service to copy media files from an
external search folder. Depending on the search-folder configuration, it may copy the
files to either a Media Store or an Output Server cache.
• It enters in the System Database the code contained in software License files, to
release the functionality contained in software plug-ins.
The Media Watcher can handle media files distributed across multiple network volumes.
Copying and registering files
The Media Watcher monitors a special folder, called the Inbox, on a Media Store. When a
media file is placed in the Inbox, the Media Watcher performs two tasks:
• It checks the file is in a valid format and registers it – it reads the file property
information (filename, size, etc.) and copies this information to an asset (database
record), which it creates for the file in the System Database.
• It moves the file to a folder inside the Media folder on the Media Store. In doing this, it
adds a suffix to the filename: "_OMN" followed by a 10-digit number based on the
date and time of registration.
