“…In such a scenario, the multimedia news program must be composed automatically from daily news archives based on the user's profiles. Other applications requiring auto-assembled multimedia presentations include query result presentations from a typical multimedia database, adaptive educational lectures, personalized TV-program delivery services, and many others [38,39,72,78,84,101,113].…”

AbstractÐDigital libraries are concerned with the creation and management of information sources, the movement of information across global networks, and the effective use of this information by a wide range of users. A digital library is a vast collection of objects that are of multimedia nature, e.g., text, video, images, and audio. Users wishing to access the digital library objects may possess varying capabilities, preferences, domain expertise, and may use different information appliances. Facilitating access to complex multimedia digital library objects that suits the users' requirements is known as universal access. In this paper, we present an object manifestation approach in which digital library objects automatically manifest themselves to cater to the users' capabilities and characteristics. We provide a formal framework, based on Petri nets, to represent the various components of the digital library objects, their modality and fidelity, and the playback synchronization relationships among them. We develop methodologies for object delivery without any deadtime under network delays.

“…Recent research on multimedia presentations concentrated on synchronization models for presentations [Stein90,RanRVK93,BlaS96,Haindl96], presentation querying languages [LSBBOO97,ACCKS96], systems for authoring, retrieval and scheduling of presentations [CandPS96,Dalal96], and automated construction of presentations [HKO97,HO97]. The area of continuous media storage servers is currently a very active research area [OBRS94,GarOS98,GhKS95].…”

“…Electronic classroom is an education environment where students decide on the length and the content of a presentation about a lecture using various constraints. The system decides on the streams included in a lecture (a presentation) as well as the graph structure of the presentation using the constraints [HKO97,HO97]. Since all properties of streams are known a priori, admission of a requested lecture into the system is equivalent to the admission of a presentation into the presentation server.…”

Most multimedia servers reported in the literature are designed to serve multiple and independent video/audio streams. We think that, in the future, multimedia servers will also serve complete presentations. A multimedia presentation contains explicitly specified synchronization information describing when each multimedia data needs to be delivered in the playout of the presentation. Multimedia presentations provide unique opportunities to develop algorithms for buffer management and admission control, as execution-time consumption requirements of presentations are known a priori. In this paper, we examine presentations in three different domains (heavyweight, middleweight, and lightweight presentations) and provide buffer management and admission control algorithms for the three domains. We propose two improvements (flattening and dynamic-adjustments) on the schedules created for the heavyweight presentations. Results from a simulation environment for the proposed algorithms are also presented.
