Overview of Aurora Playout
Aurora Playout is a playout control system that links a nonlinear editing system with an electronic
news production system, media workflow application framework, and a media server for a complete
digital solution.
Playback operators use the main Aurora Playout application to create new playlists, and to control
playlists before and during broadcasts. Aurora Playout application consists of several components
such as Clip Browser, Playlist Overview, Rundown List, Channel windows and Playlist to coordinate
playback.
Aurora Playout also has graphics workflow through an interface to the Orad graphics playout engine,
Maestro. Editors can place MOS-driven graphic elements on the timeline and then transfer graphic
timing information directly into Aurora Playout. As the story plays to air, Aurora Playout
frame-accurately triggers the Orad graphics server for a direct play-to-air as well.
