本标准定义了MXF文件与可播放基本元素容器的播放列表交换的操作模式2a，每个容器包括单个基本元素或交错的基本元素。它定义了操作限制、结构元数据对象和必须应用于MXF文件格式规范的单个属性，以便在将MXF文件交换为可连续播放的视听材料项列表时实现互操作性。操作模式2a旨在满足采集、存储和交换应用程序的要求，这些应用程序由包装在两个或多个相同类型的essence容器中的单个内容项的播放列表来满足。 操作模式2a要求内部香精容器使用身体隔板。使用主体分区对每个essence容器进行细分是可选的。

This standard defines operational pattern 2a for the exchange of an MXF file with a play-list of playable essence containers, each comprising either a single essence element or interleaved essence elements. It defines the operating restrictions, structural metadata objects and individual attributes that must be applied to the MXF file format specification to achieve interoperability when exchanging an MXF file as a list of continuously playable items of audio-visual material.Operational pattern 2a is intended to meet the requirements of acquisition, storage and interchange applications that are satisfied by a play-list of individual items of content packaged in two or more essence containers each of the same type. Operational pattern 2a requires the use of body partitions for internal essence containers. Subdivision of each essence container by using body partitions is optional.
