Abstract

In multi-way interactive computer video conferencing, the ability to simultaneously display all video inputs of all parties is often limited to a single source; this is due to technology limitations or physical space limitations on the computer desktop. This invention provides a means for managing the video presentation contained on a computer desk top during an interactive computer conference session. Specifically, it provides the user of the computer with a Graphical User Interface (GUI) for selection of the video presentation to be displayed on the computer desktop.

Manual Multiple Source Selection in Computer Assisted Video Conference

      In multi-way interactive computer video conferencing, the
ability to simultaneously display all video inputs of all parties is
often limited to a single source; this is due to technology
limitations or physical space limitations on the computer desktop.
This invention provides a means for managing the video presentation
contained on a computer desk top during an interactive computer
conference session. Specifically, it provides the user of the
computer with a Graphical User Interface (GUI) for selection of the
video presentation to be displayed on the computer desktop.

      In an interactive computer conference, software is provided to
allow all participants of the conference to have a shared workspace.
Each participant may add data to the work space in the form of
bitmaps, graphics drawings, and application output, and all other
participants are shown these additions is real time. Additionally,
full motion video information may be sent from each participant to
all other participants during the conference. In it basic use, the
video information would be a picture of the person or persons
gathered around each computer. Therefore, the other participants may
see who is involved in the conference, and have the added information
interchange of body language, etc. The video signals may also be used
for presentation of other information such as a marketing
advertisement or a visual statement of a problem. Distribution of the
video signals may be via analog or digital means.

      Now, individual workstations may be limited as to the number of
active video windows that can be displayed on the computer screen. In
many cases, this is limited to one. Even if there is more than one
active wi...
