ISO 26429-7:2008规定了合成播放列表结构。合成播放列表是单个完整数字电影作品的独立表示，例如电影、预告片或广告。 合成播放列表由一系列有序的卷轴结构组成，每个卷轴结构引用一组外部曲目文件，例如声音或图片曲目文件，这些文件将被并行复制。每个卷轴类似于电影卷轴，合成播放列表控制卷轴播放的顺序和时间。

ISO 26429-7:2008 specifies the Composition Playlist structure. The Composition Playlist is a self-contained representation of a single complete digital cinema work, e.g. a motion picture, a trailer or an advertisement. The Composition Playlist consists of an ordered sequence of Reel structures, each referencing a set of external Track Files, e.g. a sound or picture Track File, which are meant to be reproduced in parallel. Each Reel is analogous to a film reel and the Composition Playlist controls the order and timing of the playout of the Reels.
