COMPOSITION PLAYLISTS [CPLs] MUST COMPLY WITH THE DIGITAL CINEMA TITLE NAMING CONVENTION
The below describes the naming convention for the Content Title Text and Annotation Text fields in a Composition Playlist (CPL) for all Digital Cinema Packages (DCP).
The most significant information about the DCP is contained in the first 40 characters of the CPL text fields, to accommodate certain digital cinema servers with limited user interface character displays. Additional information is included for servers that can display more than 40 characters.
The title name must appear in the Content Title Text field and it may appear in the Annotation Text field. The content provider must verify the advertising title name with Val Morgan and obtain a unique ID number to prefix this, in order to ensure consistency with any existing 35mm versions.
Underscores separate each field of information in the title name. Hyphens can be used to separate words or parts within a field. No blank spaces are to be used. Generally, upper case letters are used, with lower case letters used in specific instances as described below.
The structure of the title name is as follows:
