    RT-UML in modeling of multimedia applications
    (2007) Cichoń, Paweł
    RT-UML enables a structural and behavioral description of multimedia applications including time characteristic, however it does not offer mechanisms of a multimedia objects presentation (arrangement) expression or the time constrains expression between events. This fact illustrates RT-UML lack of expressive capabilities, especially in the context of multimedia applications modeling. The presented in the paper extension of RT-UML illustrates how multimedia objects arrangement and events synchronizations can be presented, which means new type of diagrams addition to UML (presentation diagrams) and a synchronized events set class placing into the time model of RT-UML. Moreover extensions provide an application a graphical presentation of synchronized events to sequence and activity diagrams of UML, which enables time constrains of multimedia objects and their activities expression (synchronization of time events, which occur during presentation of multimedia objects). The originality of this approach relies on the extension of RT-UML syntax and on the presentation of an original method of multimedia applications modeling, which can make the production process more formalized and thus more precise.
