Collaborative multimedia documents: Authoring and presentation

Abstract Synchronized multimedia applications play an important role in a digital library environment, since they allow one to efficiently disseminate knowledge among differently skilled users through an approach, which is more direct than the classic'static'documents. In this paper, we propose a new authoring approach based on an innovative presentation structure and a new class of content-based constraints.

We have studied a mechanism for creating multimedia presentation from various multimedia objects such as video, image and text. The important points for creating multimedia presentation are specification and verification. Specification means representation for temporal relations among multimedia objects. Temporal relations specify the flow of multimedia presentation in space and time. As for verification, we should consider both syntactic and

We classify existing techniques by confronting them against two kinds of requirements: expressive power and authoring capabilities. These two sets of requirements lead to grouping multimedia authoring systems into two classes: operational ones and constraint-based ones. Both approaches provide

Distributed multimedia documents systems, distributed video servers are examples of multimedia presentations involving collaboration among multiple information sources. In such applications, objects have to be retrieved from their sources and presented to users according to specified temporal relationships. Objects retrieval in these collaborative applications is influenced by their presentation times, durations, and network throughput available to their sources. Replication of objects amongst the set of collaborating systems gives a choice for object retrieval. In this paper, we present a graph-search based algorithm for computing and negotiating throughput requirements of collaborating multimedia presentations with replicated objects. This algorithm optimizes the number of cached objects (that have already been played) for handling operations like reverse presentation.

Groupware systems have been made possible by developing algorithms and architectures which support collaborative tasks. The main roles of these algorithms are to maintain a global coherence state of the cooperative system and to control the infomation pow amongst the co-users. By architecture we mean the way the cooperative system is organised in order to enable the cooperative algorithm to work. This organisation concerns the distribution of the physical processes and files over the different machines where the co-authors are located, as well as the way the communication as enabled.

Creating high-quality multimedia presentations requires much skill, time, and effort. This is particularly true when temporal media, such as speech and animation, are involved. We describe the design and implementation of a knowledge-based system that generates customized temporal multimedia presentations. We provide an overview of the system's architecture, and explain how speech, written text, and graphics are generated and coordinated. Our emphasis is on how temporal media are coordinated by the system through a multi-stage negotiation process. In negotiation, media-specific generation components interact with a novel coordination component that solves temporal constraints provided by the generators. We illustrate our work with a set of examples generated by the system in a testbed application intended to update hospital caregivers on the status of patients who have undergone a cardiac bypass operation.

We present in this paper an integrated system that allows the management and annotation of multimedia objects stored in MPEG-7/21 repositories, and the specification and semi-automatic generation of multimedia presentations based on the content relationships existing among multimedia objects. This system is the outcome of the collaboration between the Technical University of Crete (TUC-MUSIC) and the University of Milan (UNIMI) in Task 3.10 – CoCoMA (Content and Context Aware Multimedia Content Retrieval, Delivery and Presentation) of the DELOS II European Network of Excellence on Digital Libraries. The resulting system is one of the main components of the CoCoMA infrastructure, aiming to provide contentand context-aware rich interactive multimedia presentations by controlling data fusion and metadata reuse. The integrated system utilizes the SyMPA management and presentation authoring system developed by UNIMI and the DS-MIRF framework developed by TUC-MUSIC.

For most users, authoring multimedia documents remains a complex task. One solution to deal with this problem is to provide template-based authoring tools but with the drawback of limited functionality. In this paper we propose a document model dedicated to the creation of authoring tools using templates while keeping rich composition capabilities. It is based on a component oriented approach integrating homogeneously logical, time and spatial structures. Templates are defined as constraints on these structures.
