Overview of Aurora Playout
Aurora Playout is a playout control system that links a nonlinear editing system with
an electronic news production system, asset management tool 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. With this addition, editors can place MOS-driven graphic
elements on an Aurora Edit timeline and then transfer graphic timing information
directly to Aurora Playout. As the story is then played to air, Aurora Playout can
frame-accurately trigger the Orad graphics server for direct play-to-air.
