Abstract:

Multimedia scenarios have multimedia content and inter- active events associated with computer programs. Inter- active Scores (IS) is a formalism to represent such sce- narios by temporal objects, temporal relations (TRs) and interactive events. IS describe TRs, but IS cannot repre- sent TRs together with conditional branching. We propose a model for conditional branching timed IS in the Non- deterministic Timed Concurrent Constraint (ntcc) calculus. We ran a prototype of our model in Ntccrt (a real-time ca- pable interpreter for ntcc) and the response time was ac- ceptable for real-time interaction. An advantage of ntcc over Max/MSP or Petri Nets is that conditions and global constraints are represented declaratively.
