Patents by Inventor Keith A. Lantz

Keith A. Lantz has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Two monitor videoconferencing hardware
    Patent number: 5867654
    Abstract: A multimedia collaboration system and method that integrates separate real-time and asynchronous networks--the former for real-time audio and video, and the latter for control signals and textual, graphical and other data. The system includes separate data and AV paths that interconnect a plurality of workstations. Each workstation includes two monitors--one for representing video images of the participants and the other for reproducing data interactively shared and manipulated by the participants.
    Type: Grant

  • System for teleconferencing in which collaboration types and participants by names or icons are selected by a participant of the teleconference
    Patent number: 5854893
    Abstract: A multimedia collaboration system that integrates separate real-time and asynchronous networks--the former for real-time audio and video, and the latter for control signals and textual, graphical and other data--in a manner that is interoperable across different computer and network operating system platforms and which closely approximates the experience of face-to-face collaboration, while liberating the participants from the limitations of time and distance. These capabilities are achieved by exploiting a variety of hardware, software and networking technologies in a manner that preserves the quality and integrity of audio/video/data and other multimedia information, even after wide area transmission, and at a significantly reduced networking cost as compared to what would be required by presently known approaches. The system architecture is readily scalable to the largest enterprise network environments.
