    摘要: A multimedia processing system and methods provide flexibility and modularity by separating data flow information from maintaining of stream state for multimedia components. The system includes a media processor component to process received media data, a media session to determine a timeline for events to occur for performing media processing and a topology loader component to load a topology that describes a flow for the received media data to enable processing via an extensible symbolic abstraction of media objects. The topology loader ensures that events described in the topology occur. The system also includes core layer components such as media sink components to determine a media stream for output from the multimedia processing system and a media source component coupled to supply media data for processing. The topology created in the system symbolically provides data flow information, independent of maintaining a streaming state of control information.

    摘要: A header object for a data file is comprised of sub-objects which specify properties of the data stream and contains information needed to properly verify and interpret the information within the data object. In order to allow the protection of any set of sub-objects without requiring that the sub-objects follow any specific ordering, a new sub-object is introduced which includes region specifiers identifying regions within sub-objects and verification information for those regions. This new sub-object in the header object allows the modification of non-protected regions and reorganization of sub-objects in a header without invalidating verification information.

    摘要: A flexible interface that enables an application to communicate directly with processing modules to easily control the processing of streaming data. The interface provides basic commands for applications to use to communicate with processing modules and provides the flexibility to adapt to changing standards. The interface enable an application to set the type of input and output data formats of a processing module and control when the processing module processes input data and generates output data. The processing modules enurmerate its capabilities by category, by media type, or by both category and media type. Processing modules are registered by class ID, category, whether the application needs a key, the number and types of input data types, and the number and type of output data types to register.
