Screen The scheduling target that receives its own generated playlist.
Target The display topology object that groups outputs, failover behavior, and related runtime context.
Canvas A display container concept used in the documentation for grouped display/output behavior.
Output A playback path associated with a target or display topology.
Failover The logic or mode that determines how the system responds when multiple output paths exist.
On-Screen The output path currently presenting the live display result.
