Abstract
Systems and methods for efficiently distributing digital cinema files from a server to a theater are disclosed. The systems and methods may comply with DCI requirements. A server updates an original composition playlist, updates a track file associated with the updated composition playlist, and distributes the updated composition playlist and updated track file to one or more theaters over a communications network. The theater is configured to store the updated track file at a storage containing copies of all track files associated with the updated composition playlist and update the theater's original composition playlist to the updated composition playlist. The server may have a database configured to track the composition playlists and associated track files present in each theater in the system.
