Publication number: 20170214626Abstract: A computer device can establish multiple links with a network, with each link having different characteristics such as bandwidth, jitter, latency, and the like. The computer device can execute applications of different types, and can select for each application one of the links with the network based on both the type of application and the characteristics of the link. The computer device can thereby select the best link for each application, improving overall communication via the network.Type: ApplicationFiled: January 25, 2016Publication date: July 27, 2017Inventors: WAYNE DUNLAP, Charles Musta

Patent number: 9392221Abstract: A videoconferencing apparatus automatically tracks speakers in a room and dynamically switches between a controlled, people-view camera and a fixed, room-view camera. When no one is speaking, the apparatus shows the room view to the far-end. When there is a dominant speaker in the room, the apparatus directs the people-view camera at the dominant speaker and switches from the room-view camera to the people-view camera. When there is a new speaker in the room, the apparatus switches to the room-view camera first, directs the people-view camera at the new speaker, and then switches to the people-view camera directed at the new speaker. When there are two near-end speakers engaged in a conversation, the apparatus tracks and zooms-in the people-view camera so that both speakers are in view.Type: GrantFiled: March 5, 2013Date of Patent: July 12, 2016Assignee: Polycom, Inc.Inventors: Jinwei Feng, Peter Chu, Wayne Dunlap, Jonathan Gallmeier

Patent number: 9264369Abstract: A router of a network is configured to manage routing of packets based on executing applications. The network communicates packets of information between endpoints coupled to the network. Each packet is assigned to a traffic class based on the application associated with the packet. The router manages routing of received packets based on the traffic classes associated with the received packets. Accordingly, the router can determine routing priority, bandwidth, acknowledgment policy, and other routing management information based on the applications associated with received packets.Type: GrantFiled: December 6, 2010Date of Patent: February 16, 2016Assignee: QUALCOMM IncorporatedInventors: Ben Menchaca, Wayne Dunlap

Patent number: 9172774Abstract: A router can process the data received from the local area network at a network protocol stack local to the router, while processing data received from the wide area network normally. The offloading of the stack processing from the source of the data to the router reduces the number of network hops that both packets based on the received data, and acknowledgements from the destination of the packets, must travel, thereby reducing communication latency. In addition, offloading the stack processing to the router can reduce the processing load at the data source. Further, the router can implement different quality of service or other processing protocols for the local area and wide area traffic.Type: GrantFiled: April 13, 2011Date of Patent: October 27, 2015Assignee: QUALCOMM IncorporatedInventors: Charles A. Musta, Wayne Dunlap, Ben Menchaca

Patent number: 9025764Abstract: Audio from a near-end that has been acoustically coupled at the far-end and returned to the near-end unit is detected and suppressed at the near-end of a conference. First and second energy outputs for separate bands are determined for the near-end audio being sent from the near-end unit and for the far-end audio being received at the near-end unit. The near-end unit compares the first and second energy outputs to one another for each of the bands over a time delay range and detects the return of the sent near-end audio in the received far-end audio based on the comparison. The comparison can use a cross-correlation to find an estimated time delay used for further analysis of the near and far-end energies. The near-end unit suppresses any detected return by muting or reducing what far-end audio is output at its loudspeaker.Type: GrantFiled: December 9, 2013Date of Patent: May 5, 2015Assignee: Polycom, Inc.Inventors: Peter L. Chu, Wayne Dunlap

Patent number: 8458357Abstract: Techniques are disclosed for setting network communication parameters at a network interface based on the types of applications being executed at one or more computer devices that interface with the network. Thus, for example, the network interface can set the communication bandwidth, priority, or combination thereof, for each executing application based on the application type. By setting the network communication parameters for each application based on the application type, the applications can communicate with the network more efficiently.Type: GrantFiled: June 29, 2010Date of Patent: June 4, 2013Assignee: Qualcomm IncorporatedInventors: Benjamin Menchaca, Harlan T.

Publication number: 20080168355Abstract: A presentation device includes an embedded web server for transmitting images representative of presentation information to network-connected terminals concurrently with the display of such presentation information at the presentation site. The images may be viewed at the terminals by pointing a conventional web browser to a DNS name or IP address associated with the presentation device. Certain of the terminals may be given presenter privileges, wherein the users of the presenter terminals may control aspects of the presentation such as slide sequencing by engaging the appropriate controls displayed within the browser window. In this manner, presentations may be viewed and controlled remotely using a conventional browser interface.Type: ApplicationFiled: February 22, 2008Publication date: July 10, 2008Applicant: POLYCOM, INC.Inventors: WAYNE DUNLAP, JEFFREY C.

Patent number: 6760749Abstract: A multimedia distribution device includes an embedded stream encoder and an embedded stream server for encoding and transmitting, through utilization of streaming technology, audio and video content originating from a videoconference site and received through a network interface, to network-connected terminals. In situations in which the videoconference includes the presentation of slides or other content, the device may include a file conversion engine for converting the presentation content received through a data interface into a standard graphic image format, for synchronous distribution with the audio and video content stream. The multimedia content may be viewed in a multiple-window interface, wherein the audio and video content is presented by a streaming media player, and the presentation content is displayed in a separate window. Additionally, the interface may include an interactive text entry interface, through which the viewer may submit comments or questions to the conference presenters.Type: GrantFiled: May 10, 2000Date of Patent: July 6, 2004Assignee: Polycom, Inc.Inventors: Wayne Dunlap, Michael Hogan, Kristin Dunn, Oden J.
