ISO/IEC 23004-1:2007 specifies the architecture of the MPEG Multimedia Middleware technology. Multimedia Middleware (M3W) allows application software to execute multimedia functions with a minimum knowledge of the inner workings of the multimedia middleware as well as to support a structured way of updating, upgrading and/or extending the multimedia middleware. The architecture consists of the following.

• M3W API:




• multimedia API (specified in detail in ISO/IEC 23004-2);


• interfaces for audio broadcast decoding, processing and rendering;


• interfaces for video broadcast decoding, processing and rendering;


• IPMP interfaces;


• governance interfaces.




• Support API (specified in detail in ISO/IEC 23004-3 to ISO/IEC 23004-7):




• interfaces for instantiation of services (Runtime Environment and Service Manager);


• interfaces for interaction with remote services (REMI-P and REMI-R, REMI stands for Remote Method Invocator);


• interfaces for Resource Management;


• interfaces for Component Download;


• interfaces for Fault Management;


• interfaces for Integrity Management.




• Realization technology (specified in detail in ISO/IEC 23004-3):




• Unit of Trading;


• Unit of Loading;


• Unit of Instantiation;


• standard interfaces:




• navigation between interfaces,


• binding,


• access to public attributes.
