ISO/IEC 23006-2:2016规定了一组应用程序编程接口（简称MXM API），以便在MPEG-M设备上运行的MPEG-M应用程序可以访问其中间件中包含的标准多媒体技术，作为MPEG-M引擎，如ISO/IEC 23006-1所规定。 MXM API分为两类: -MPEG-M引擎API，即单个MPEG-M引擎API的集合，提供对单个MPEG技术（例如视频编码）或一组MPEG技术的访问（如果方便）； -MPEG-M Orchestrator API，即能够创建MPEG链的特殊MPEG-M引擎（称为Orchestrator引擎）的API- M引擎来执行高级应用程序调用，例如；播放一段视频；，与通常的低级MPEG-M引擎API调用相反。

ISO/IEC 23006-2:2016 specifies a set of Application Programming Interfaces (called for short MXM APIs) so that MPEG-M Applications running on an MPEG-M Device can access the standard multimedia technologies contained in its Middleware as MPEG-M Engines, as specified by ISO/IEC 23006？1. The MXM APIs belong to two classes: - the MPEG-M Engine APIs, i.e. the collection of the individual MPEG-M Engine APIs providing access to a single MPEG technology (e.g. video coding) or to a group of MPEG technologies where this is convenient; - the MPEG-M Orchestrator API, i.e. the API of the special MPEG-M Engine (called Orchestrator Engine) that is capable of creating chains of MPEG-M Engines to execute high-level application calls such as "Play a video", as opposed to the typically low-level MPEG-M Engine API calls.
