....in section 3.2.1. We are investigating other video algebraic composition operations. These include binary operations that will achieve simultaneous termination, overlay of video streams, synchronization on events, a general synchronization operator (similar to operators defined by Fiume et al. [5]) and non determinism. 3.1.2 Presentation Because multiple algebraic video nodes can be scheduled to play at any specific time within one video expression, the playback may result in concurrent video streams that require simultaneous screen display. The number of distinct streams depends on the ....

Fiume et al. fium87] defined a temporal scripting language intended for object oriented animation. Such objects can be viewed today as independent, but inter communicating processes. Their motivations included the wish to specify the coordination of objects, real time constraints, and concurrency. It is not ....

....document systems are in the predocument formatter stage. They typically require authors to create temporal layouts manually by positioning media segments on a document timeline [8, 16, 18, 19] a tedious and error prone process. Other manual methods include temporal scripting languages [9] and temporal relation trees [15, 12] It is time for multimedia document systems to take over this task, generating the temporal layouts automatically. Analogous to automatic spatial formatting, automatic temporal formatting requires authors to specify both the media and temporal formatting ....

....using runtime signalling to detect and correct media delays, and incrementally running a formatter to handle documents generated on the fly. We now briefly describe these algorithms. In the simplest case, a temporal specification can be converted into a graph or a temporal scripting language [9], which is then processed by an interpreter that serves as a runtime formatter. A merge approach can be used when a partial layout, with one predictable and at least one unpredictable portions, is available. This algorithm manages the individual portions of the layout, and when it detects the ....

Buchanan and Zellweger [2] make a good comparison between many systems of interest, namely: Xavier [13] Firefly [3] CMIF [14] Trellis [23] Geneva [11], and MODE [1] Also of interest is OCPN [16] and its derivations [22, 21] This paper presents a novel model, the morena model, for the development of hypermedia systems. Although many of the individual features of morena are also present in other systems, morena brings together these features ....

....that coordinate the interaction between the agents, and its evaluator. A separate interface, called Gurn, builds the SPAM graph using calls to library routines that build SPAM sub graphs that implement interpolators, constraints, and synchronization operators such as those found in Fiume et al. [fium87]. The details of Gurn are beyond the scope of this paper. The interface between an agent and SPAM (agents do not directly communicate with each other) is called an actuator and represents the parameter or group of parameters to animate. Thus for a freeform surface modeller an actuator is ....

Fiume et al. detail a number of useful operators [fium87] that all have isomorphic representations as SPAM graphs. 5 Keyframing and Dynamic Simulation Using SPAM we built a simple application combining three agents, a display engine that displays a double pendulum, a dynamic simulation engine that performs dynamics on the pendulum, and an input agent ....

....object can be defined in a way that is consistent with data hiding and object independence. The idea of high priority operations is promising, though it is not clear how that may be used to affect the control of the interrupted activity. We are experimenting with techniques for animating objects [Fium87]. We expect that the triggering and constraint mechanisms provided by Hybrid will be useful in binding animated objects to the active objects they represent. The separation of specification and realization given by the object oriented approach means that we shall be able to respecify our animated ....

....ground between the flexibility and control of general concurrency specifications and the ease of use of timeline and annotation approaches. To do this we employ the fourth primary approach to temporal specification the compositional approach. Under the compositional approach (see for example [Fium87, Gibb91]) multimedia documents are constructed by composing small presentations into larger ones. Temporal relationships are created using special scheduling and synchronization composition operators. This approach allows techniques such as timelines or general synchronization notations to be applied, ....

....in user interfaces development tools is an attractive alternative, but difficult to implement in this environment because of the dynamic nature of the document being edited. We are currently examining several other paradigms for our high level authoring environment including scriptbased editors [Fium87], iconic visual programming languages [Koeg92] programming by rehearsal [Finz84] and the walk through metaphor. A number of techniques to enhance the framework described here are also in our future plans. These include: inclusion of more types of interactive objects and more flexible use of them ....

We give a description of our system and illustrate its functionality with selected examples. 1 Introduction Object oriented systems are believed to be of considerable value in domains such as software engineering [Cox86] computer graphics animation [FTD87] and office automation [Zdo84, WL86] They combine well known techniques (modularization, data abstraction) with new concepts, and give a new framework for the implementation of distributed applications. Object oriented languages usually exhibit the following characteristics: ffl The traditional ....

....data or for more complex objects a procedure generating the object. However, in every case an object appears as a set of variables mostly just real numbers that define the properties of the object. An animation of the object is given by assigning different values to a subset of the variables [6, 8, 15, 17]. There exist different ways to assign values to variables: explicitly by data sets, interactively by spline functions [5] functions curves [23] etc. or procedurally by simulations or iterations [11, 19] In any way, they can be implemented as functions or procedures in a programming language ....

....instance, use a timeline representation where temporal transformations can be interactively specified by moving and stretching the timelines. Another approach to constructing complex multimedia presentations is to specify concurrency and synchronization using a temporal scripting language [3][6]. For instance, TEMPO [3] provides a set of temporal operators which are used to combine activities one activity, perhaps the presentation of an audio sequence, can be specified as occurring in parallel, or before, or offset from, a second, visual, activity. A powerful feature of TEMPO is that, ....

These operators must know the ending time of an activity; they are described in detail in [Fium87]. They have been abandoned in our current version of TEMPO, because we found too limiting the constraint of having only activities with a fixed duration. 5 Implementation of basic expressions Using the temporal operators, complex hierarchies of expressions can be specified.

....overview Visual Scripting ended. In our environment, for example, we are using scripting ideas in several very disparate areas: animation, music, and objectsheets. We have implemented a system for computer animation in which scripting controls the synchronization of animated actors [6]. The set of motions to be performed in a scene is specified hierarchically: local behaviours of actors, either programmed or scripted, can be encapsulated and then coordinated with other actors through the use of scripting operators that specify temporal relationships between participants. ....
