....Services temporal model to provide temporal access control (TAC) operations such as fast forward and reverse playout. Research related to this effort includes modeling of unstructured data for content based retrieval [26, 25, 39, 41, 42, 46] modeling of the temporal component of multimedia data [8, 9, 19, 16], modeling of application specific multimedia data (movies) 11, 23, 24, 31, 35, 36] systems support for delivery of audio and video and video servers [1, 29, 43] and network based VOD system design [14, 13, 27, 33, 34] The remainder of this paper is organized as follows. In Section 2 we ....

....are only audio and video (and subtitles) for the VOD application. Timing information is also captured with node attributes, allowing the assembly of component elements during playout. Most proposed models for multimedia data are based on such a temporal interval based (TIB) representations (e.g. [10, 16, 17]) including our model [19, 22] Temporal intervals can be used to model multimedia presentation by letting each interval represent the presentation or playout duration of some multimedia data element, such as a still image or an audio segment. The specification of timing for a set of intervals is ....

....the components. A component provides the basic abstractions for the processing of continuous media streams, such as video or audio streams. A continuous media stream is defined to be a sequence of data units, each of which is associated with a media time (for a detailed definition e.g. see [12]) The nature of a component s processing depends on the type of the component. We distinguish between source com CINEMA An Architecture for Distributed Multimedia Applications 5 ponents, which produce (e.g. capture) data streams, sink components that consume (e.g. play out) streams, and ....

....because it eliminates the starvation problem. When compared with the atomic objects, the retrieval of composite objects using a multi disk hardware platform has received less attention. A number of studies have analyzed composite objects and temporal relationships from a conceptual perspective [24, 47, 29, 25]. Their focus is on alternative abstract representations of composite objects. Other studies [45, 28, 37] concentrate on the networking aspects of a geographically distributed system and propose techniques to support the temporal relationships of a composite object when displayed at a remote ....

A number of studies have analyzed composite objects and temporal relationships from a conceptual perspective [Her90, VM93, LG93, HFK95]. Their focus is on alternative abstract representations of composite objects.

....1) The combination of natural and synthetic time dependencies can describe the overall temporal requirements of any pre orchestrated multimedia presentation. Temporal information can be encapsulated in the description of the data using the object oriented paradigm (e.g. Gibbs [10] Herrtwich [12]) Using such schemes, temporal information such as a time reference, playout time units, temporal relationships, and required time offsets can be maintained for specific multimedia objects. If the data are periodic, this approach can define the time dependencies for an entire sequence by defining ....
