.... as a powerful tool for multimedia document composition and presentation [41] In hierarchical synchronization specification, a complex multimedia object is organized in a tree structure consisting of nodes, which denotes serial or parallel presentation of the outgoing subtrees [5] Haindl [18] presented a model, which captures various level of multimedia synchronization granularity. Each data object is recursively decomposed into an ordered set of data subsets. The level of such decomposition depends on applications and the lower level subsets reflect the finer synchronization. This ....

....of actions [Hoep 91b] Thus, the specification of temporal aspects of a presentation behavior takes into consideration the possible user input as well as the synchronization issues of media objects. There is a large body of research results on multimedia synchronization models [BlSt 93, LiGh 90, Hain 96, PraRa 93] One interesting work introduces the notion of elastic time for multimedia objects. The synchronization requirement arises from the interobject temporal relations, which are either imposed at the creation time of media objects and termed as live synchronization, or set up ....

....other multimedia presentation models in the literature such as petrinet based [LGha 90] or constraint based models, we believe that most of these models can be mapped into a graph based one. For extensive reviews of alternativemultimedia presentation models, please see [Prabha 96, Ste 90, BlSt 96, Hain 96] We model multimedia presentations directly as graphs in a multimedia database. So, our (object oriented) data model includes graph, node, and edge classes whose objects represent, respectively, multimedia presentations, multimedia data, and precedence edges between multimedia This research is ....

....data streams and the synchronization requirements related to the presentation of dynamic data such as audio and video during browsing. Its specification requires adequate models capable of describing sequencing and synchronization policies. According to Blakowski and Steinmetz [1] and Haindl [6], to be applicable to the design of large and complex hypermedia applications, a model should satisfy some important requirements, providing: i) mechanisms for describing hierarchical structure and hierarchical levels of synchronization; ii) mechanisms for expressing incomplete timing ....

The XHMBS model successfully addresses the requirements identified by Blakowski and Steinmetz [1] and Haindl [6] for the specification of hypermedia applications. The hierarchical structuring of the application and the structured hierarchical navigation are strongly supported by the model through the Show hview operation. XHMBS separates the structure from the content specification; supports specification ....

In order to be applicable to the design of large and complex multimedia hypermedia documents, the model should be able to satisfy some important requirements [1, 3, 7]: 1. the capacity of describing hierarchical document structures, as well as hierarchical levels of synchronization 2. the capacity of expressing incomplete timing specifications 3. the capacity of representing user interactionsbased synchronizations 4. the capacity of expressing a media object ....

Presently, multimedia presentations, created by multimedia authoring tools, are used in many applications such as computeraided training, computer aided learning, online books, etc. We believe that multimedia presentations, modeled as presentation graphs ( Ste 90] BlSt 96] Hain 96] will be much more commonly used in the feature, e.g. in digital libraries and electronic books. Multimedia presentation graphs are acyclic graphs with directed edges, used for visual specification of multimedia presentations. Querying multimedia presentation graphs based on content is ....

At the time of creation of multimedia information, the temporal constraints among various data streams, necessary at the time of playback, can be expressed in the form of a model [12,13]. In a distributed multimedia environment the multimedia information has to be identified, assembled, and communicated to a single or multiple remote users in a timely manner. The network requires to establish appropriate connections, allocate resources, and transport information efficiently to ....
