....to specify the execution scenario of their component activities. Our proposition is mainly based on works axed on time specification for the management of multimedia data presentation. Such works have resulted in temporal relations definition [13] 14] 15] causal relations between intervals [16] and synchronous and asynchronous relations specification [9] In reference to these works and after having identified useful relations between activities we have built the six temporal operators presented in fig.1, where A and B are activities process, and d is a delay eventually null. Temporal ....

....Finally, par max let al..l the components play until their natural termination. These operators differ from the relationships of [3] they do not describe relationships between intervals, but impose these relationships: the beginning and or the end of an interval starts and or stops other intervals [5]. Figure 2: The seven base Allen s relationships between time intervals We can derive other operators from these basic ones: The before relationship is easily obtained from the seq operator by introducing instances of the sub classes of DelayMedia between each component. The same is possible to ....

The requirements constitute a metric along which selected multimedia document models are analyzed in Section 4. Temporal model. A temporal model (see [17, 21, 6]) describes temporal dependencies between the media elements of a multimedia document. One can nd four types of temporal models: point based temporal models, interval based temporal models, and event based temporal models. Another way to specify temporal relations between media elements is by the ....

We conclude in Section 5 summarising our work and giving hints for future research. 2. MULTIMEDIA APPLICATION MODELLING Modelling of MAPs is a matter of current research [Duda95, Hirz95]. As a part of our research we have specified object oriented models for multimedia applications. More specifically, we have specified models for compositions of multimedia objects in MAPs [Vazi95c] and models for representation of MAP interactive scenarios based on events [Vazi95a, Vazi95b] The ....

The Interval Expressions form the basis ....

....semantics are explicitly given. THE Z Y X MODEL FOR MULTIMEDIA DOCUMENTS AND PRESENTATIONS 13 Temporal Operator Elements. The temporal operator elements determine the temporal relationships between the presentation elements. As outlined above, our temporal model is based on Interval Expressions (Duda and Keramane, 1995). In the following, we present the definition, specific parameters, and semantics of the temporal operator elements par, seq, loop, and delay. For an illustration of the temporal operator elements see Figure 1.8. The semantics of the par operator element is that the presentation elements bound to ....

.... unknown duration that occur, for instance, in the context of user interaction in multimedia presentations (e.g. Object Composition Petri Nets (OCPN) LG93] Therefore, enhanced interval based temporal models have been proposed to handle open time intervals and indefinite interval relationships [DK95, HFK95, WR94] In an event based model of time, events determine the temporal course of the presentation. An event is connected to actions and when an event occurs, e.g. a video reaches a certain point in time, the corresponding actions, typically start and stop of the presentation of other ....

We have defined a model called Interval Expressions for structured temporal composition of interactive dynamic multimedia presentations [1, 2]. The model extends Algebraic Video [3] that used a set of basic operations on video segments to create a desired video stream. The elementary entities of our model are media segments that have inherent temporal behavior. They may be traditional multimedia objects containing video, audio, ....
