Retrieval schedules based on resource availability and flexible presentation specifications

A distributed multimedia document presentation involves retrieval of objects from one or more document servers and their presentation at the client system. The presentation of the multimedia objects has to be carried out in accordance with the specification of temporal relationships between the objects. The retrieval of multimedia objects from the document server(s) is influenced by factors such as temporal specification of objects presentations, throughput offered by the network service provider, and the buffer resources on the client system. Flexibility in the temporal specification of the multimedia document may help in deriving an object retrieval schedule that can handle variations in network throughput and buffer resource availability. In this paper, we develop techniques for deriving a flexible object retrieval schedule for a distributed multimedia document presentation. The schedule is based on flexible temporal specification of the multimedia document using the difference constrai nts approach. We show how the derived retrieval schedule can be validated and modified to ensure that it can work with the offered network throughput and the available buffer resources.

Context-aware adaptation of multimedia documents for consistent presentations

We propose in this paper a context-aware adaptation technique for SMIL encoded multimedia documents. Our approach is mainly dedicated to run in compile-time but we discuss also how it can be used in runtime. Our algorithm aims at improving the execution of a multimedia presentation. This is achieved by scheduling object pre-fetchings in the presentation while monitoring bandwidth and memory space availabilities. For this effect, a request pattern computed from the temporal graph of the SMIL specification is exploited in order to apply an optimal policy to select which objects should be pre-fetched, real time delivered or discarded, even. The algorithm can be used as a tool to evaluate and to monitor the QoS of a presentation. At compile time, it makes it possible to assess whether the QoS of a presentation can be guaranteed after enforcing specific context-oriented adaptations. At authoring stage, this algorithm can be used, for instance, to produce different alternative sub-codes, such that each one is adapted to run in a specific context. In runtime, the algorithm can provide a mechanism to monitor the elastic time computation in case of a mismatch occurrence. In order to advocate our proposal, some experimentation results performed on a simulation platform are reported.     

Towards Graph Transformation Based Generation of Visual Editors Using Eclipse

This work discusses the state-of-the-art of visual editor generation based on graph transformation concepts on one hand, and using the Eclipse technology which includes the Graphical Editor Framework (GEF), on the other hand. Due to existing shortcomings in both approaches, we present a combined approach for a tool environment that allows to generate a GEF-based editor from a formal, graph-transformation based visual language specification.     

Transformation and exchange of multimedia objects in distributed multimedia systems

One of the challenges in the design of a distributed multimedia system is devising suitable specification models for various schemas in different levels of the system. Another important research issue is the integration and synchronization of heterogeneous multimedia objects. In this paper, we present our models for multimedia schemas and transformation algorithms. They transform high-level multimedia objects into schemas that can be used to support the presentation and communication of the multimedia objects. A key module in the system is the Object Exchange Manager (OEM). In this paper, we present the design and implementation of the OEM module, and discuss in detail the interaction between the OEM and other modules in a distributed multimedia system.     

View management in multimedia databases

Abstract. Though there has been extensive work on multimedia databases in the last few years, there is no prevailing notion of a multimedia view, nor there are techniques to create, manage, and maintain such views. Visualizing the results of a dynamic multimedia query or materializing a dynamic multimedia view corresponds to assembling and delivering an interactive multimedia presentation in accordance with the visualization specifications. In this paper, we suggest that a non-interactive multimedia presentation is a set of virtual objects with associated spatial and temporal presentation constraints. A virtual object is either an object, or the result of a query. As queries may have different answers at different points in time, scheduling the presentation of such objects is nontrivial. We then develop a probabilistic model of interactive multimedia presentations, extending the non-interactive model described earlier. We also develop a probabilistic model of interactive visualization where the probabilities reflect the user profiles, or the likelihood of certain user interactions. Based on this probabilistic model, we develop three utility-theoretic based types of prefetching algorithms that anticipate how users will interact with the presentation. These prefetching algorithms allow efficient visualization of the query results in accordance with the underlying specification. We have built a prototype system that incorporates these algorithms. We report on the results of experiments conducted on top of this implementation. Received June 10, 1998 / Accepted November 10, 1999     

A framework for synchronous delivery of time-dependent multimedia data

Multimedia data often have time dependencies that must be satisfied at presentation time. To support a general purpose multimedia information system, these timing relationships must be managed to provide utility to both the data presentation system and the multimedia author. Timing management encompasses specification, data representation, temporal access control, playout scheduling, and run-time intermedia synchronization. In this paper we describe the components of our framework for supporting time-dependent multimedia data encompassing these areas and how they are assembled into a unified system.
