Dynamic Playlists
Dynamic Playlists allow you to easily update media playlists in multiple presentations. For example, if you need to add a set of daily announcements to multiple presentations, and you don’t want to update each presentation separately, you can add a single Dynamic Playlist to all of your presentations. When you update the Dynamic Playlist, every presentation that includes the Dynamic Playlist receives the new content. In this way, a single update can reach multiple presentations.
Note
Dynamic Playlists support a maximum of 500 content files. If you need dynamic playback of more than 500 files, create two or more Dynamic Playlists to hold the content.

Dynamic Playlist Advanced Uses
Dynamic Playlist Behaviors
Dynamic Playlists support constant addition or removal of content. The deployment of all updates depends on the playlist's Update Interval value. When the update interval begins, the player communicates with the network to check the cached schedule against the network schedule. BrightSign players will always defer to the network for content scheduling.
When a Dynamic Playlist is updated such that it removes content, the change will be reflected instantly. When a Dynamic Playlist is updated with new content, the player will begin downloading the new files when a presentation containing the playlist begins. New content needs to fully download before it can be displayed.
BrightSign players only check for un-loaded content at the start of a presentation. As a result, it is possible that the presentation will call for content to play that has not completely downloaded. If content is not fully cached, the presentation will skip the item and continue with the presentation. When content is fully cached, it will display properly the next time the presentation calls.
Dynamic Playlist Preload
While Dynamic Playlists are powerful, due to the player content download behavior noted above, it can be difficult to have a presentation play as desired when adding or using content with large file sizes. In order to best solve this problem, it is recommended to set up a preload data feed.
A preload data feed utilizes the Dynamic Playlist and data feed behaviors to cache content before the start of playlist's presentation. BrightSign players will never delete cache contents that are required for presentations on the same day. A Dynamic Playlist can therefore be preloaded by adding the playlist as a hidden data feed in other presentations. The following example details how to set up a preload data feed:
