As multimedia systems deal with a variety of temporally interrelated
media items, synchronization is an important issue in those systems.
One part of synchronization is the representation of temporal
information. In contrast to traditional computing tasks, multimedia
imposes new requirements on the representation of time.
Specifically, a fine-grained and a flexible temporal model is
required. Therefore, a number of temporal models have been suggested
by various authors. This paper evaluates and classifies a selection
of the most common existing models applying fundamental statements
of the time theory and temporal logic. Learning from the deficits of
the existing models, a new temporal model based on interval
operators is proposed for multimedia systems.
