This part of ISO\/IEC 14478 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\/IEC 14478, this component will also be referred to as \u201cMultimedia Systems Services\u201d, and abbreviated as MSS.<\/p>\n

The Multimedia Systems Services constitutes a framework of \u201cmiddleware\u201d \u2014 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.<\/p>\n

The Multimedia Systems Services encompasses the following characteristics:<\/p>\n

    \n
  1. \n

    provision of an abstract type for a media processing node, extensible through subtyping to support abstractions of real media processing hardware or software;<\/p>\n<\/li>\n

  2. \n

    provision of an abstract type for the data flow path or the connection between media processing nodes, encapsulating low-level connection and transport semantics;<\/p>\n<\/li>\n

  3. \n

    grouping of multiple processing nodes and connections into a single unit for purposes of resource reservation and stream control;<\/p>\n<\/li>\n

  4. \n

    provision of a media dataflow abstraction, with support for a variety of position, time and\/or synchronization capabilities;<\/p>\n<\/li>\n

  5. \n

    separation of the media format abstractions from the dataflow abstraction;<\/p>\n<\/li>\n

  6. \n

    synchronous exceptions and asynchronous events;<\/p>\n<\/li>\n

  7. \n

    application visible characterization of object capabilities;<\/p>\n<\/li>\n

  8. \n

    registration of objects in a distributed environment by location and capabilities;<\/p>\n<\/li>\n

  9. \n

    retrieval of objects in a distributed environment by location and constraints;<\/p>\n<\/li>\n

  10. \n

    definition of a Media Stream Protocol to support media independent transport and synchronization.<\/p>\n<\/li>\n<\/ol>\n

    The Multimedia Systems Services rely on the object model of ISO\/IEC 14478-1 (Fundamentals of PREMO) and the object types and non-object data types defined in ISO\/IEC 14478-2 (PREMO Foundation Component).<\/p>\n","protected":false},"excerpt":{"rendered":"
