Appeal No. 2003-1070

Invention
The invention relates to a method and apparatus for
controlling the timing of the invocations of events within a
computer runtime environment. Specifically, the invention
relates to a method and apparatus for controlling the timing of
the invocation of multimedia events within a Web page runtime
environment. See page 1 of Appellants’ specification. Web pages
are composed of various multimedia elements, controls, and
applets as defined by the Hypertext Markup Language (HTML) for a
given Web page. Multimedia can be characterized as some
combination of visual media, audio media and time. Multimedia is
an open environment, with timing being the common thread across
all multimedia events. Multimedia experiences, such as the
movement of graphics and the playing of sound, require
coordinated execution of these events. For instance, the playing
of a sound bite of a door slamming should be coordinated with the
animation of the door closing so the sound is heard upon the
visual closing of the door. Providing synchronized multimedia
experience is complicated because timing control information is
not inherent in the content of a HTML document. Past attempts of
providing such a synchronization and timing control activities
