Patent number: 8305914Abstract: A method for adjusting latency in a video conference signal originating from a video conference camera and encoder is described herein. Latency in a video conference connection between more than two video conference sites is measured. The latency between each of the more than two video conference sites is compared with a latency threshold. Parameters of the video conference camera and encoder associated with each video conference site are adjusted by a video controller to modify the image quality of the video signal if the measured latency of a respective video conference connection is below the threshold.Type: GrantFiled: April 30, 2007Date of Patent: November 6, 2012Assignee: Hewlett-Packard Development Company, L.P.Inventors: Jeffrey Thielman, Mark Gorzynski

Patent number: 8208005Abstract: A system and method of determining the identity of a caller in a local room from a remote room includes a local image capture device for capturing a plurality of images of a caller in the local room in real time. A remote codec receives the plurality of images of the caller. A remote viewscreen displays the plurality of images of the caller in real time in the remote room. A remote display monitor displays the plurality of images in real time after two-way communication is established between the local room and the remote room. The method includes establishing one-way communication between the local room and the remote room, transmitting the plurality of images of the caller to the remote room, displaying the plurality of images of the caller in real time on the remote viewscreen, and establishing two-way communication between the local room and the remote room.Type: GrantFiled: July 31, 2007Date of Patent: June 26, 2012Assignee: Hewlett-Packard Development Company, L.P.Inventors: Jeffrey Thielman, Thomas G. Acevedo
