Abstract:
An automatic process for producing professional, directed, production crew quality, video for videoconferencing is described. The process includes a method for positioning a 360 degree panoramic strip view of a room. The method includes receiving motion detection data, accepting presence sensor data, receiving video data from cameras related to a room view, and centering individuals in a room view, based on the received motion detection data, the accepted presence sensor data and received video data. The method also includes zooming onto the centered individuals in the room view, obtaining sound source localization data and active talker information, and determining how to arrange the display of individuals in a logical manner that is visually pleasing and aides understanding. Rule based logic is applied to assist with the automatic processing of video into director quality video production. Various video sources may be used as video stream sources for the automated system.
Abstract:
Examples hybrid topologies of a conferencing system are disclosed. An example of a hybrid topology may comprise a plurality of endpoints and a central entity. Each of said plurality of endpoints may provide its primary video stream and audio stream to said centralized entity. The centralized entity provides the primary speaker stream and the mixed audio stream to each of said plurality of endpoint participants. In addition, some of plurality of endpoint establishes low bandwidth/low resolution media streams with other of said plurality of endpoint participants for non-speaker video.
Abstract:
A videoconferencing endpoint includes at least one processor a number of microphones and at least one camera. The endpoint can receive audio information and visual motion information during a teleconferencing session. The audio information includes one or more angles with respect to the microphone from a location of a teleconferencing session. The audio information is evaluated automatically to determine at least one candidate angle corresponding to a possible location of an active talker. The candidate angle can be analyzed further with respect to the motion information to determine whether the candidate angle correctly corresponds to person who is speaking during the teleconferencing session.
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.
Abstract:
A logical module, referred as Load Balancer Module (LBM), is disclosed which listens to one of certain common predefined port number. These well-known ports for receiving communication video conference signaling and control protocols is thereafter load balanced and multi-plexed to a number of instances of protocol stack applications. By balancing the multi-media data stream across a multitude of application instances multiple multi-media data streams may be serviced and processed by a single internet protocol host processor. A mutipoint control unit (MCU) may therefore process multiple input data streams containing multi-media video conferencing information.
Abstract:
An endpoint optimizes bandwidth by initiating a peer-to-peer conference with a plurality of remote devices, generating a first quality list comprising a first device of the plurality of remote devices from which to receive a first data stream at a first quality level, transmit a request to the first device to receive the first data stream at the first quality level, determining that a second device of the plurality of remote devices is not a member of the first quality list, and in response to determining that the second device of the plurality of remote devices is not a member of the first quality list, transmitting a request to the second device to receive a second data stream at a second quality level.
Abstract:
An incidental virtual meeting (IVM) system deployed in multiple rooms can be used to provide a “virtual cafeteria” allowing for incidental meetings and video conferences. Wall endpoints in each room may detect the presence of a person in a proximity to the IVM (wall) endpoint and establish a connection to the associated wall endpoint in the other room, to allow unplanned meetings to occur. A room may have multiple wall endpoints, allowing the room to be connected to more than one other rooms.
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.
Abstract:
A videoconferencing device that determines a spatial arrangement of the video streams output at a first endpoint based on a number of display devices being utilized at the first endpoint and a number of cameras being utilized at each of the one or more additional endpoints.
