ISO/IEC 23004-2:20 07规定了MPEG多媒体中间件(M3W)技术的多媒体应用编程接口(API)。该多媒体API提供了一组灵活的可互操作的媒体功能，适用于具有不同功能的多个产品和多个应用领域。ISO/IEC 23004-2:20 07规定了以下内容:用于音频广播解码、处理和呈现的接口；用于视频广播解码、处理和渲染的接口；IPMP接口；治理接口。这些接口提供了M3W平台提供的多媒体功能的统一视图，但足够灵活，允许不同的M3W平台供应商区分自己。

ISO/IEC 23004-2:2007 specifies the multimedia application programming interface (API) of the MPEG Multimedia Middleware (M3W) technology. This Multimedia API provides a flexible interoperable set of media functions suitable for use in multiple products with different capabilities and in multiple application domains.

ISO/IEC 23004-2:2007 specifies the following:

• interfaces for audio broadcast decoding, processing and rendering;


• interfaces for video broadcast decoding, processing and rendering;


• IPMP interfaces;


• governance interfaces.

These interfaces provide a uniform view to the multimedia functionality offered by M3W platforms, but are flexible enough to allow different M3W platform vendors to distinguish themselves.
