Abstract: A videoconferencing unit for enhancing direct eye-contact between participants can include a curved fully reflective mirror to reflect the image of the near end to a camera. The curved mirror can be placed in front of the display screen near a location where images of faces/eyes of far end participants are to appear. In another example, the videoconferencing unit can include a disintegrated camera configuration that provides an air gap between a front lens element and a rear lens element. The front lens element can be located behind an aperture within the display screen. The air gap can provide an unobstructed path to light from projectors and therefore avoid any undesirable shadows from appearing on the display screen. In another example, the videoconferencing unit can include a combination of the disintegrated camera configuration and mirrors for providing direct eye contact videoconferencing.

Abstract: Content presented in association with a transmitting endpoint is obtained by the transmitting endpoint and transmitted to a receiving endpoint of a videoconference, along with associated information regarding interaction of a presenter with the content at the transmitting side. The receiving endpoint presents the presented content obtained from the transmitting endpoint similar to the presentation format at the transmitting side. Where the original presentation format is not suitable for transmission, a video image of the content in the original presentation format may be transmitted. An intermediate control unit, such as a multipoint control unit, may relay content and associated information between transmitting and receiving endpoints.

Abstract: A media relay conferencing system includes a media relay multipoint control unit and a media relay endpoint that handle needs for Intra frames in an efficient way, improves the conferees experience, and reduces the load on the resources associated with that media relay videoconference by reducing the number of Intra frames and lowering the impact of Intra frames when they are needed. In some embodiments, when a requiring media relay endpoint requests an Intra frame for a video stream received from a presenting media relay endpoint, a media relay multipoint control unit may respond by requesting the presenting media relay endpoint to synchronize a reference frame in an encoder of the presenting media relay endpoint, which encodes the relevant relay compressed video stream, with a reference frame in a decoder of the requiring media relay endpoint.

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.

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: 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: A videoconferencing unit comprises a display screen configured to display a video data stream comprising images of a far end participant. A processor is adapted to decode the video data stream and generate a modified region of the video data stream. The modified region of the video data stream is displayed on the display screen at a location where images of eyes of the far end participant are displayed on the display screen. A camera is configured with a lens to capture images of a near end participant through the modified region of the video data stream, with at least a portion of the lens positioned within the modified region of the video data stream.

Abstract: Methods and systems for cancelation of table noise in a speaker system used for video or audio conferencing are disclosed. Table noise is cancelled in one embodiment by providing a signal or a message whenever a key is depressed on a keyboard or a mouse is clicked. When the key depression signal or message is received, the system evaluates whether speech is occurring. If speech is not occurring, then the microphone in the system is muted. However, if speech is occurring, the microphone is not muted for a period of time to allow the speech to be transmitted to the far end. This allows the conference to be continued in the presence of keyboard sounds if speech is occurring at the same time but also silences the keyboard sounds if speech is not occurring.

Abstract translation: 公开了用于视频或音频会议的扬声器系统中用于消除表噪声的方法和系统。 在一个实施例中，通过在键盘上按下键或点击鼠标时提供信号或消息来消除表噪声。 当接收到按键抑制信号或消息时，系统评估是否发生语音。 如果没有发生语音，则系统中的麦克风静音。 然而，如果发生语音，则麦克风不会被静音一段时间，以允许语音被发送到远端。 这样就可以在出现语音的同时存在键盘声音的情况下继续进行会议，但是如果没有发生语音，则会使键盘声音静音。
