Covers a set of Multimedia System Services (MSS) that can be used by application developers in a variety of computing environments, focusing on multimedia applications in a heterogeneous, distributed computing environment.

This part of ISO/IEC14478 defines a standard set of multimedia system services that can be used by multimedia application developers in a variety of computing environments. The focus is on enabling multimedia applications in a heterogeneous, distributed computing environment. Throughout this part of ISO/IEC14478, this component will also be referred to as “Multimedia Systems Services??, and abbreviated as MSS. The Multimedia Systems Services constitutes a framework of “middleware??— system software components lying in the region between the generic operating system and specific applications. As middleware, the Multimedia Systems Services marshals lower-level system resources to the task of supporting multimedia processing, providing a set of common services which can be used by multimedia application developers. The Multimedia Systems Services encompasses the following characteristics: provision of an abstract type for a media processing node, extensible through subtyping to support abstractions of real media processing hardware or software; provision of an abstract type for the data flow path or the connection between media processing nodes, encapsulating low-level connection and transport semantics; grouping of multiple processing nodes and connections into a single unit for purposes of resource reservation and stream control; provision of a media dataflow abstraction, with support for a variety of position, time and/or synchronization capabilities; separation of the media format abstractions from the dataflow abstraction; synchronous exceptions and asynchronous events; application visible characterization of object capabilities; registration of objects in a distributed environment by location and capabilities; retrieval of objects in a distributed environment by location and constraints; definition of a Media Stream Protocol to support media independent transport and synchronization. The Multimedia Systems Services rely on the object model of ISO/IEC14478-1 (Fundamentals of PREMO) and the object types and non-object data types defined in ISO/IEC14478-2 (PREMO Foundation Component).
