本标准规定了可互操作主格式（IMF）的合成播放列表（CPL）。合成播放列表是一个完整的IMF合成的单一版本（特写、插曲、预告片、广告等）的表示。它包含描述合成和同步其基本本质所需的信息，例如播放或转码。它是一种可扩展的、人类可读的结构，专为基于文件的操作而设计。

This standard specifies the Composition Playlist (CPL) for the Interoperable Master Format (IMF). The Composition Playlist is a representation of a single version of a finished IMF composition (feature, episode, trailer, advertisement, etc). It contains the information necessary to describe the composition and synchronize its underlying essence, e.g. for playout or transcoding. It is an extensible, human-readable structure designed for file-based operations.
