Interactive Computer Conference Server

      This invention provides a means for managing real time
interactive communication between multimedia-enabled workstations
when those workstations are not connected by traditional
communications means. Specifically, this invention provides a means
for extending the ability for electronic interchange of data among
computer terminals by adding a multimedia conferencing server
component to that interchange network.

      Interchange of data between computer terminals has advanced in
recent years with the addition of central data repositories, LAN
connections and LAN attached information servers, and computer
conferencing tools which enable one end user to 'point' to
information that is being presented on the computer screen of other
users, thus enabling one end user to highlight information being
presented on multiple screens. The computer has been further enhanced
with the ability to present full motion video, audio, high quality
images and animations.  Yet the focus for using these new data types
has been 'one-to-many'.  That is, the multimedia presentation is
prepared by a multimedia professional, and stored on the computer
resource. Through interaction with the end user, the multimedia
presentation is presented by the computer at a later time. This is
strictly a computer interacting with the end user. To share this
information among several computers, and therefore several end users,
an identical copy of the presentation must be available at each
computer, or the computers must be connected by a high-speed
communication link such as a LAN. Even in these cases, there are only
a few applications which can support real time interaction of
computer-generated information which is required if the end users are
in a conferencing or brainstorming scenario (i.e., information that I
generate in real time is presented to you instantly, plus I have the
ability to point at the shared data and you see where I am pointing).
But when the two computers are separated by a long distance, are not
on the same LAN, or are connected by low speed switched networks, the
interactive real time requirement cannot be met.

      Another recent technology development has been the full motion
video conference room. This technology provides a means for
individuals to gather at predetermined locations and exchange audio,
video and graphical information through a satellite or terrestrial
communication network with another location that is similarly
equipped. The heart of this process is a device called a CODEC. This
device provides for the digitization of the analog audio and video
signals as well as a path for the transmission of encoded graphics.
When two conference rooms so equipped are conn...
