Overview

Playlist Elements

The hierarchy of a Show Playlist is intended to allow
inclusion of either Content (CPL), other Sub-Playlist(s) or
Commands. The structure of a typical Show Playlist is
shown in the illustration below.

Composition Playlist (CPL)

Composition Playlists (CPL) are shown on the right in the
above illustration and are the reference files required to
play the content.
CPLs exist on the lowest level of the Show Playlist (SPL)
hierarchy, and consist of the component files (e.g., video,
audio, subtitles) required for content playback.

Show Playlist (SPL)

As shown above, Show Playlists (SPL) are show lists that
consist of one or more CPLs with specified commands.
Multiple SPLs (containing CPLs and commands) can be
added as Sub-Playlists to a single additional layer of the
hierarchy.

Commands

Commands are Playlist Elements which are either
Automation Controls, i.e. external device triggers, (dim
house lights, open curtain, etc.) or Auditorium Unit control
events such as, Media Block Audio Control functions
(Muting) or Projector Control functions (Douser).
Commands or Functions may be designated as 3D type and
when these are included in a Playlist the SPL is identified
as a 3D Playlist even though no 3D Content is included.
