Definitions
The following terms, which apply to Extron media players, are used throughout this
manual:
•
Digital Cinema Package (DCP) — A folder that contains all of the files necessary for
the JMP 9600 to play a presentation. This folder can include reel files (video images
and audio data), subtitle files, the composition playlist (CPL), and the associated
packing list and asset map. All of these file types are detailed below and are encoded
to the Digital Cinema Initiatives (DCI) specification.
NOTE: All of the files within the DCP are automatically created when using the
Extron JPEG 2000 Encoding Software (see “
” in the
“Detailed System Interaction” section).
•
Reel — A reel is a file that contains either compressed video content or
uncompressed audio content. These files have the *.mxf file extension, for example
reel_1_video.mxf. Reels are typically 10 to 20 minutes long, so a larger presentation
may consist of multiple video and audio reels.
•
Composition Playlist (CPL) — An xml file that contains all of the information
on how the files for a specific presentation should be played back, including the
filenames and locations of the reels and how the audio and subtitles are synchronized
with the picture. The CPL can specify one video reel and one audio reel or multiple
reels of both types.
•
Clip — The video and audio material content specified by a CPL file. The terms “clip”
and “DCP” can be used interchangeably.
•
Asset map file — A file that is similar to the CPL file, but the asset map also lists the
frame rate and duration of the clip.
•
Packing list file — A file that contains information and identification about each of
the individual files that are delivered in a DCP.
•
Playlist — An xml file that can be the name of a single DCP presentation (a clip) or a
sequential list of clips. Playlists must contain DCPs that are all of the same resolution,
color space, frame rate, and number of audio channels to load successfully in the
JMP 9600.
NOTE: Pay attention to the difference between a “playlist” and a “composition
playlist.”
