Chapter 18 Schedule Media to Play and Commands to Run
Concepts
• You cannot use the Schedules > Play Now feature with external deployment servers.
• All deployments to external servers require that you use Schedules > Play in Future.
• Video files do not play at all when you deploy to an FTP server a presentation whose MPEG files are:
–
Requested through Microsoft Proxy Server.
–
Requested through Microsoft Internet Security and Acceleration Server.
• When your media library in DMM is the source for a file that you deploy as part of a presentation,
and when you choose an FTP server as the target to receive that file, DMM transfers copies of the
relevant file to all of the FTP servers that you have registered. After the transfer is completed, DMM
deletes the original file from its media library, and then changes the relevant presentation so that it
uses a URL instead of a local path. The URL that DMM enters automatically is specific to whichever
FTP server you registered first.
• When an HTTP URL is the source for a deployed file, and when the pathname on the source server
contains subdirectories that do not exist on the target FTP server, DMM automatically creates the
required subdirectories on the FTP server.
Content Delivery Network Restrictions
ACNS
• We recommend that you avoid using immediate deployments with ACNS, due to the amount of time
required to distribute assets throughout your network and to its edge. If you do so despite this
recommendation, DMM always uses the default ACNS channel. You cannot use any other channel.
ECDS
• We recommend that you avoid using immediate deployments with ECDS, due to the amount of time
required to distribute assets throughout your network and to its edge. If you do so despite this
recommendation, DMM always uses the default ECDS channel. You cannot use any other channel.
WAAS
• We recommend that you avoid using immediate deployments with WAAS, due to the amount of time
required to distribute assets throughout your network and to its edge.
Scenarios
• Methods to Pre-empt Only One Instance of a Recurring Event, page 18-5
Methods to Pre-empt Only One Instance of a Recurring Event
In some cases, you might want to do something one time, or for a limited time, that overlaps with a
recurring event. For example, you might schedule a presentation to run from 9:00 a.m. to 6:00 p.m.
every weekday in the month of March, but want to show a different presentation on the second Tuesday
in March.
The challenge is that your DMP cannot prioritize contradictory events that are scheduled to start
simultaneously. However, there are several ways to pre-empt a recurring event.
