Abstract

This invention provides a means for accessing prerecorded video productions when the source for those video productions is not directly attached to the requesting computer. Specifically, this invention provides a means for extending the ability for electronic interchange of data among computer terminals by adding a full motion video server component to that interchange network. Remote access of this type allows multiple users access to the full motion video for a fraction of the cost of having each end user have direct access.

Automatic Multiple Source Selection in a Video Conference

      This invention provides a means for accessing prerecorded
video productions when the source for those video productions is not
directly attached to the requesting computer. Specifically, this
invention provides a means for extending the ability for electronic
interchange of data among computer terminals by adding a full motion
video server component to that interchange network. Remote access of
this type allows multiple users access to the full motion video for a
fraction of the cost of having each end user have direct access.

      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 on the computer screen.
Yet the source for presenting information in the full motion video
screen was limited to devices dedicated to the presenting terminal.
That is, in order to present full motion video on a terminal screen,
equipment for generation of the video signal (such as a Video Tape
Recorder, Video Laser Disk Player, or Video Camera) must be attached
directly to and dedicated to the terminal where the video
presentation is to be shown. It is further observed that many of
these video sources may be controlled by the computer to which they
are attached. That is, signals from the computer to the video source
may specify the starting and ending location for playing a video
clip, as well as start, pause and stop the playing of the video clip.
