We introduce a tuple-based model for specification of events among media segments in a multimedia presentation. A multimedia presentation contains various kinds of multimedia objects such as audio, video, images, and so on. The organization of a presentation is a complex task in that the display order of presentation content (in time and space) must be specified. The critical decisions for presentation construction include content selection, content organization, and content delivery. Once the decision is made on the organization of the presentation content, it must be conveyed to the end user in the correct organizational order and in a timely fashion. Assuming that a set of multimedia segments gets organized into a presentation graph, this conceptual model formalizes a complete presentation using event-points for these segments. End-user environments of multimedia presentation are considered for the playout such as (i) the one without any constraint, (ii) another one with a single constraint, and (iii) the third one with multiple constraints (one constraint for each type of segments in the organized presentation). In accordance with these limitations (without violating any of the specified constraints), three methods are given for constructed presentations to be presented.
