Abstract: A technique for merging conference session dialogs allows presenting content and media streams from a non-Skype endpoint to a Skype multipoint control unit (MCU), so that they present a single caller in a conference with both media and content. A signaling adapter intercepts session dialogs and merges or other modifies. When adding the non-Skype endpoint, requests from a content server are dropped while requests from the MCU handling non-Skype media streams are forwarded to the Skype MCU. Responses to the request from the MCU are also forwarded to the content server. When creating subscription dialogs, requests from the content server are modified to appear as if they came from the MCU, while responses go back to the proper requester. Conference notifications are forked to go to both the content server and the MCU. Because Skype uses separate media and content dialogs, merging of audio/video and content dialogs may be omitted. By merging dialogs, user experience is improved.

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: 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.

Abstract: A P2P configuration where only the active talker or talkers are providing media streams, to reduce uplink bandwidth demands on an active talker, participants relay the active talker stream to other participants. A signaling server determines the closest participant receiving a requested stream and with available bandwidth to relay the requested stream to a requesting participant and controls the provision of the relayed stream. In certain cases, an additional intermediate participant may relay the requested stream.

Abstract: A videoconferencing system has a plurality of displays arranged side-by-side. Top loudspeakers are arranged adjacent the tops of the displays, and bottom loudspeakers are arranged adjacent the bottoms of the displays. A control unit operatively coupled to the displays and the loudspeakers routes video to each of the displays and routes audio corresponding to each display to any of the top and bottom loudspeakers arranged adjacent the display. Thus, the top and bottom loudspeakers form a vertical pair of loudspeakers that output the corresponding audio for its respective display. In this way, the audio for the video of a given display is perceived by participants to originate from the center of the given display. If one of the loudspeakers is not provided, gain setting and mixing between adjacent sets of loudspeakers can produce a virtual loudspeaker for the one that is missing.

Abstract: A conferencing system includes a computer system coupled to a base station via a first connection. The computer system receives display identification data associated with the base station via the first connection. The computer system uses the received information to determine connectivity information associated with the base station. Also, the computer system connects to the base station via a second connection using the determined connectivity information. The computer system and the base station communicate data (e.g., video data, etc.) using the first connection or the second connection. The first connection can be based on video interface technology. For example, High-Definition Multimedia Interface (HDMI) technology, DisplayPort technology, any other video interface technology with capabilities for information that is the same as or similar to enhanced extended display identification data (E-EDID information) or DisplayID information, etc.

Abstract: A telecommunication device featuring customizable, presence state-based recipient availability notification alerts a call initiator that a call target having an initially unavailable presence state has become available as indicated by the current presence state of the target. An option to initiate a call is then presented to the call initiator.

Abstract: Blurriness in a video image transmitted over a lossy network can be reduced by filtering the decoder output to determine whether updating of the reference frame based on the current video data is indicated. An update may be appropriate if the decoder output is sharper than the contents of the display buffer after the last update. Additionally, an update may be appropriate if there was a significant change to the underlying image, and thus to the encoder's input. Whether such a change has occurred can be determined by analyzing the prediction mode, motion vectors, and pixel data of the output image.

Abstract: An automatic process for producing professional, directed, production crew quality, video for videoconferencing is described. Rule based logic is integrated into an automatic process for producing director quality video for videoconferencing. An automatic process can include a method for composing a display for use in a video system having an active talker video stream and a panoramic view video stream having more than one person in video. The method can include determining a region of interest in a panoramic view video using motion detection and presence sensors, and preparing the panoramic view video by centering the region of interest and by zooming towards the region of interest, based upon the location of persons in the panoramic view video. The method includes determining placement of panoramic view video on a composite display to prevent the panoramic view video overlaying display of an active talker on the active talker video stream.
