A data processing apparatus has an input that provides a sequence composed
of events and a script. The events are data determining time-sequential
occurrence of multimedia matter, while the script is a program modifying
the time-sequential occurrence of multimedia matter. The data processing
apparatus operates when reference is made to the provided sequence for
executing the script to rewrite the events, and provides the sequence
containing the rewritten events in response to the reference for a
modifying the time-sequential occurrence of the multimedia matter.
