Delivery Manager’s Modes of Operation
Delivery Manager’s Modes of Operation
Depending on the endpoint driver being used, Delivery Manager can react to content
delivered to the monitored locations, actively seek content required for schedules or be
manually controlled by an operator. The mode of operation is defined by the selected
workflow or mode option in the endpoint configuration profile.
Content Changed (or Drop Box) Mode
This mode uses Delivery Manager's own internal workflow engine to determine which new
media files need to be registered or updated and at what time.
Content Changed mode requires that a network share is configured as a monitored
location within the appropriate endpoint configuration. Delivery Manager monitors the
location for the presence of new or updated files. Delivery Manager processes new content
intelligently, prioritizing material required for playout.
When new or updated files are detected, Delivery Manager does one of the following:
File status Delivery Manager action
File is required by a currently active
schedule Delivery Manager moves the file to an iTX store and
updates the database with the new asset's information
and availability by placing the task in the active jobs
queue.
New file that is not yet required by
any known schedule Delivery Manager creates an Asset Record in the
database. In order to avoid unnecessary network
bandwidth, the file will not be processed until required.
When the file appears in a schedule it will then be
transferred to an iTX location and the Asset Record
updated.
An updated version of a file that
already exists in iTX Delivery Manager updates the Asset Record for that file.
If the new version of the file is required for playout it will
be transferred to iTX and the original version will be
deleted.
File not yet required for playout The updated version of the file remains in the monitored
location until it is required
The internal workflow that handles all Content Changed Mode actions needs to be selected
in the configuration options for the endpoint’s configuration profile, using the Content
Changed Workflow field.
Search Media (or Missing Materials) Mode
When configured in Search Media mode, the endpoint responds to “Find Content” requests
from Delivery Manager clients. When a search request is received, the CIFS driver searches for
any configured file type with the same name as the search request in the configured search
folder, and any of its sub folders (if configured), excluding any specifically configured exclude
folders. If a matching file is found, the driver generates a block of Asset XML detailing the media,
and returns it to Delivery Manager.
