“…Then, Bailey et al [24] have proposed a multimedia synchronization toolkit, named the Nsync. According to Hakkoymaz and Ozsoyoglu [1] multimedia presentation is -a synchronized and, possibly, interactive delivery of multimedia data to users‖. Hakkoymaz [7] describes a multimedia presentation in reference to the presentation of multimedia segments with particular arrangement using a number of output devices.…”

“…Many researches in multimedia presentation area are recently concerned with stored multimedia presentation with some types of constraints [1][2][3][4][5][6][7][8]. These constraints are used to synchronize each multimedia data in order to attain the goal of its author.…”

“…Spatial and temporal constraints are the most interesting ones as the topic of the researches in this area [4,[12][13]. The modeling of the multimedia presentations is commonly approached by graph theory and formal definition to analyze the model [1,[3][4]7]. Moreover, in stored multimedia presentation, between the author and the end-user are separated, and may never see each other directly before and after presentation.…”

As the complement of the stored multimedia presentation, live multimedia presentation (LMP) is similar to the stored multimedia presentation except for the process of selecting, authoring, constructing and playing out the multimedia elements are done during presentation time. Unfortunately, there is no established model of LMP as well as in stored multimedia presentation with its SMIL. This paper proposes some basic concepts for developing any LMP application, and then from such concept we design a model of LMP using formal definition. Finally, to verify the model we used scenario-based and developed an application as a tool to accomplish the verification process.

In this paper, we present a methodology for automated construction of multimedia presentations. Semantic coherency of a multimedia presentation is expressed in terms of presentation inclusion and exclusion constraints. When a user specifies a set of segments for a presentation, the multimedia database system adds segments into and/or deletes segments from the set in order to satisfy the inclusion and exclusion constraints. We discuss the consistency and the satisfiability of inclusion and exclusion constraints when exclusion is allowed. Users express a presentation query by (a) pointing and clicking to an initial set of desired multimedia segments to be included into the presentation, and (b) specifying an upper bound on the time length of the presentation. The multimedia database system then finds the set of segments satisfying the inclusion-exclusion constraints and the time bound. Using priorities for segments and inclusion constraints, we give two algorithms for automated presentation assembly and discuss their complexity. To automate the assembly of a presentation with concurrent presentation streams, we introduce presentation organization constraints that are incorporated into the multimedia data model, independent of any presentation. We define four types of presentation organization constraints that, together with an underlying database ordering, allow us to obtain a unique presentation graph for a given set of multimedia segments. We briefly summarize a prototype system that fully incorporates the algorithms for the segment selection problem.

“…In Hak96, HO96a], we have described how to associate a playout agent to each segment in the presentation, which is a lightweight process (a thread) that plays out the corresponding multimedia segment. In particular, we describe a semaphore-based technique for the automated generation, synchronization and termination of playout agents in order to implement the concurrent presentation playout as de ned by the presentation graph Hak96,HO96a]. Figure 1 shows the constraint types and their functionality in our multimedia presentation system.…”

A methodology to dynamically adjust the multimedia presentations as a result of user interactions during the playout is introduced. A constraint-driven approach is described for the automated assembly, organization and playout of presentations from multimedia databases. To allow interactive user control over the playout of an automatically generated presentation, a set of control buttons are provided. Using these buttons, the user can control and change the flow of the presentation in a variety of ways. Interactive user control during the presentation playout, however, can introduce new delays in the original presentation schedule of multimedia segments and possibly change playout constraints. To account for these delays and changes, strategies to (a) dynamically reorganize the subpresentations into a presentation, (b) replace segments with their compacted clips, and (c) delete segments on the presentation graph are proposed.
