Appeal No. 2003-1070
Application 09/021,727
control object 530 corresponding to the specified sequencer set.
The sequencer control object 530 contains several methods
including play, pause, stop and seek. See page 24 of Appellants’
specification. The action set 540 includes many methods for
controlling the execution of the associated timeline. The action
set 540 notifies 562 the timer 560 when the next event on the
timeline is scheduled. The action set 540 then remains dormant
until it receives another sequencer control command or until it
receives a call 564 to its sink interface notifying the action
set 540 to invoke the next event. See page 25 of Appellants’
specification.
Independent claims 30 and 50 are representative of
Appellants’ claimed invention and are reproduced as follow:
30. A computer implemented method for executing a plurality
of events, the method comprising:
reading one or more event-timing statements in a mark-up
language document, the event-timing statements being in a user-
viewable format and each specifying an execution time for one of
the plurality of events, wherein each of the execution times is
expressed according to its position along a single timeline
common to the plurality of events; and,
executing each of the plurality of events at its execution
time as designated in the one or more mark-up language
statements.
