Library – Composition Playlist #
The Composition Playlist (CPL) section in the TMS Library provides a complete overview of all ingested DCP content—including features, trailers, advertisements, tests, and automation reels—stored on the LMS or any connected screen.
This is where operators review, audit, clean, and inspect content before it is assigned to show playlists or playback sessions.
