  • Patent number: 9544541
    Abstract: A videoconferencing system has a videoconferencing unit that use portable devices as peripherals for the system. The portable devices obtain near-end audio and send the audio to the videoconferencing unit via a wireless connection. In turn, the videoconferencing unit sends the near-end audio from the loudest portable device along with near-end video to the far-end. The portable devices can control the videoconferencing unit and can initially establish the videoconference by connecting with the far-end and then transferring operations to the videoconferencing unit. To deal with acoustic coupling between the unit's loudspeaker and the portable device's microphone, the unit uses an echo canceller that is compensated for differences in the clocks used in the A/D and D/A converters of the loudspeaker and microphone.

  • Patent number: 9531996
    Abstract: Systems for videoconferencing are designed for where people are seated around a video conferencing system. The systems include a camera so the far site can see the local participants and the systems include displays that show the far site. The displays are properly aligned with the cameras so that when people at the far site view the displayed images of the near site, it looks like they have eye contact with the near site. Obtaining the alignments of the camera and the displays to provide this apparent eye contact result requires meeting a series of different constraints relating to the various sizes and angles of the components and the locations of the participants.

  • Patent number: 9491406
    Abstract: Techniques allow seamless transitioning of a mesh-based videoconference to a bridged videoconference. Criteria are defined for use in a triggering point function that may be evaluated to determine whether to make the transition. Escalation logic in an escalation manager may be used to manage the transition, allowing some participants to connect via a multipoint control unit, which is in turn a participant in the mesh-based videoconference, with the escalation manager relaying media streams from the mesh-connected participants. The mesh-connected participants may then drop their mesh connections without disruption to the videoconference. Escalation logic in the endpoints may be used as an alternate to an escalation manager unit.

  • Patent number: 9478233
    Abstract: A conferencing system and method involves conducting a conference between endpoints. The conference can be a videoconference in which audio data and video data are exchanged or can be an audio-only conference. Audio of the conference is obtained from one of the endpoints, and speech is detected in the obtained audio. The detected speech is analyzed to determine that the detected speech constitutes a speech fragment, and an indicia indicative of the determined speech fragment is generated. For a videoconference, the indicia can be a visual cue to be added to video for the given endpoint when displayed at other endpoints. For an audio-only conference, the indicia can be an audio cue to be added to the audio of the conference at the other end points.

  • Patent number: 9473740
    Abstract: In a system and method of conducting a videoconference, a videoconferencing unit detects an activation related to a presentation device at a near-end of the videoconference. The unit stores a current orientation of at least one camera and directs the at least one camera at the presentation device. At this point, the unit begins outputting to a far-end at least one of (i) video captured of the presentation device with the at least one directed camera and (ii) content displayed with the presentation device. At some point, the unit detects a deactivation related to the presentation device at the near-end and then redirects the at least one camera to the stored orientation so the videoconference can proceed as before.

  • Patent number: 9467657
    Abstract: Dynamically adapting a continuous presence (CP) layout in a videoconference enhances a videoconferencing experience by providing optimum visibility to regions of interest within the CP layout and ignoring regions of no interest. Based on the CP layout, a CP video image can be built, in which a conferee at a receiving endpoint can observe, simultaneously, several other participants' sites in the conference. For example, more screen space within the CP layout is devoted to presenting the participants in the conference and little or no screen space is used to present an empty seat, an empty room, or an unused portion of a room. Aspect ratios of segments of the CP layout (e.g., landscape vs. portrait) can be adjusted to optimally present the regions of interest. The CP layout can be adjusted as regions of interest change depending on the dynamics of the video conference.

  • Patent number: 9392221
    Abstract: 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.
