Playlist Element

A primary or secondary event in a playlist.

Primary Event

A program in a playlist. Appears as the parent element. Templates and Viz Commands can be added as secondary events.


For imported (and subsequently updated) playlists, you can create sets of rules that govern how templates can be automatically associated with certain events within a playlist. Rules are useful when external playlists do not already contain Secondary Events.

Rules are defined on a per-template basis. Both master and editable templates support rules. In addition, rules can also be applied to Viz Commands (see Defining Viz Command Elements). Rules are applied upon Importing Playlists from External Sources or Updating Playlists of external origin.
