Patent number: 8659636Abstract: A method for executing a video conference is provided that includes receiving one or more audio streams associated with a video conference from one or more end points and determining an active speaker associated with one of the end points. Audio information associated with the active speaker may be received at one or more media switches. One or more video streams may be suppressed except for a selected video stream associated with the active speaker, the selected video stream propagating to one or more of the media switches during the video conference. The selected video stream may be replicated such that it may be communicated to one or more of the end points associated with a selected one of the media switches.Type: GrantFiled: October 8, 2003Date of Patent: February 25, 2014Assignee: Cisco Technology, Inc.Inventors: Scott S. Firestone, Walter R. Friedrich, Nermin M. Ismail, Keith A. Lantz, Shantanu Sarkar, Luke K. Surazski, Duanpei Wu

Patent number: 7908320Abstract: 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.Type: GrantFiled: November 1, 2005Date of Patent: March 15, 2011Assignee: Pragmatus AV LLCInventors: Lester F. Ludwig, J. Chris Lauwers, Keith A. Lantz, Gerald J. Burnett, Emmett R. Burns

Patent number: 7889636Abstract: A communication system includes a call agent that coordinates and supervises communications between endpoints. The call agent allocates a QoS agent for each endpoint involved in a call. The QoS agents generate reservations for the call in order to provide the call with a guaranteed amount of bandwidth and an established QoS. Each endpoint or location associated with an endpoint has a reservation policy that determines how calls are to be handled when a reservation is or is not obtained and when a reservation is lost or obtained during a call. The communication system is able to handle reservations, or the lack thereof, during various situations like on hold, call transfer, call forwarding, conference call, and shared line services.Type: GrantFiled: May 24, 2005Date of Patent: February 15, 2011Assignee: Cisco Technology, Inc.Inventors: Subhasri Dhesikan, Denise G. Caballero-McCann, Kevin E. Miller, Rongxuan V. Chen, John K. Restrick, Jr., Scott A. Henning, Martin W. Wu, Keith A. Lantz, David Sauerhaft

Patent number: 7437411Abstract: First and second users log in using at least one of a plurality of respective communication devices. Address information of the communication devices used by the first and second users to log in are sent to respective first and second servers, separated from each other by at least one wide area network. A user identifier for the second user is displayed in a quick dial list of user identifiers selected by the first user. The first user selects the displayed second user's identifier to request communication with the second user. The first user also selects a communication type. In response, the first server is queried to obtain the current address information for the selected second user. The received address information is used to establish the selected communication type, over the wide area network, between the first and second users.Type: GrantFiled: January 15, 2007Date of Patent: October 14, 2008Assignee: Avistar Communications CorporationInventors: Lester F.

Patent number: 7437412Abstract: First and second users log in using respective communication devices. Address information of the communication devices are sent to respective first and second servers. At the communication device used by the first user, a graphical icon representing the second user is retrieved from the first server, and is displayed in a quick dial list of first-user-selected user identifiers on the display. The first user selects the icon to request communication with the second user. Real-time communication types are displayed on a display associated with the communication device used by the first user. In response, the first server is queried to obtain the current address information for the selected second user. The received address information is used to establish a communication type. If a communication type is selected by the first user, the real-time communication is of the selected type. Otherwise, the real-time communication is of a default communication type.Type: GrantFiled: January 19, 2007Date of Patent: October 14, 2008Assignee: Avistar Communications CorporationInventors: Lester F.
