Motivation • Interactive multimedia = multimedia content + interaction with
the environment + spatial and temporal organization • Some examples of interactive multimedia systems: ◦ Live performances. ◦ Museum installations. ◦ Plastic art installations.

Motivation • Interactive Scores1(IS) is a formalism for composing and
executing interactive multimedia scenarios. 1Antoine Allombert. “Aspects Temporels d’un Système de Partitions Musicales Interactives pour la Composition et l’Exécution”. PhD thesis.

Motivation • Interactive Scores1(IS) is a formalism for composing and
executing interactive multimedia scenarios. • An interactive scenario is composed of: ◦ Textures → multimedia processes ◦ Structures → hierarchy ◦ Temporal relations ◦ Interaction points 1Antoine Allombert. “Aspects Temporels d’un Système de Partitions Musicales Interactives pour la Composition et l’Exécution”.

Motivation • i-score2 is a software for interactive scenarios based
on IS. ◦ Composition time → CSP problem ◦ Execution time → Timed Petri Net (TdPN) • IS mixes two temporal paradigms used in the current multimedia tools3: time-line and time-flow. • i-score has been used successfully during the last years4. 2Website: http://i-score.org/ 3Myriam Desainte-Catherine, Antoine Allombert, and Gérard Assayag. “Towards a Hybrid Temporal Paradigm for Musical Composition and Performance: The Case of Musical Interpretation”.

Timed Automata Framework True Parallel Implementation • Multimedia applications perform
real-time, compute-intensive, and data-intensive tasks that sometimes the performance of standard computers is not sufficient. • Most of the multimedia applications are executed on architectures and operating systems that do not provide low-latency and real-time performance (e.g., i-score).

Concluding Remarks

53.

Concluding Remarks Overview We proposed a framework for the specification,
verification and execution of interactive scenarios. • Extension of interactive scenarios with guarded interaction points. • Automatic verification of scenarios using mature and robust tools (i.e., UPPAAL). • We showed the verification of some properties. • Synthesizing of scenarios into reconfigurable hardware, allowing their low-latency and real-time execution.

Concluding Remarks Future Work • Extension of the Timed Automata
model with : ◦ A coherent model for loops11. ◦ Notions for improvisation12. • Encoding of the Timed Automata model into the tiled programming13. • Validation of the hardware implementation using SystemVerilog Assertions14 • Study of other verification and validation techniques, such as Model-Based Testing and game semantics. 11Abdeldjalil Boudjadar, Frits W.
