摘要： Customizing a conferencing system based on proximity of a participant. A first participant may be detected as being proximate to a first conferencing system. For example, the first participant may provide user input to check in to the first conferencing system. Alternatively, the conferencing system may automatically detect the first participant (e.g., by automatically detecting a personal device of the first participant). In response to detecting the proximate participant, the first conferencing system may be automatically customized for the participant.

摘要： Providing high availability in videoconferences system. A first plurality of videoconferencing devices of a first type may be monitored. Additionally, a second plurality of videoconferencing devices of a second type may be monitored. During this monitoring, at least one device of the first plurality of videoconferencing devices performs activities corresponding to a respective videoconference and at least one device of the second plurality of videoconferencing devices performs activities corresponding to the respective videoconference. In response to failure of a one of the devices associated with the respective videoconference, failover to a second device of the same type may be performed. After performing failover, the second device performs the activities corresponding to the respective videoconference that the original device was performing.

摘要： Initiating a conference in a conferencing system (e.g., a videoconferencing or audioconferencing system). Input may be received to the conferencing system from a mobile communication device. The input may specify one or more participants in the videoconference, e.g., by selecting from contact information stored on the mobile communication device. Accordingly, the conferencing system may initiate the conference based on the received input. The videoconference may include the one or more participants selected from the contact information stored on the mobile communication device.

摘要： Determining a buffer size in a videoconference. In some embodiments, one or more of various different error correction methods may be used in a videoconference. For example, forward error correction (FEC) may be used and/or retransmission of lost packets (ReTxLP) may be used, e.g., based on a packet loss threshold. Where FEC is used, a buffer size of a receiving videoconferencing device may be determined based on the FEC rate. Where ReTxLP is used, a buffer size of the receiving videoconferencing device may be determined based on a retransmission latency.

摘要： In various embodiments, a Multipoint Control Unit (MCU) or another video conferencing device (e.g., an endpoint) may generate a video frame that includes video images of two or more video conferencing endpoints. The video frame may then be sent to another video conferencing device that may receive the video frame and separate the two or more video images into separate video images. In some embodiments, the video frame may be separated into its separate images using, for example, metadata sent along with the video frame. The metadata may include video image identifiers and location information (e.g., coordinates in the video frame) of the video images. In some embodiments, the separated video images may be provided to a compositor that may composite the separated video images, for example, into a new layout.
摘要翻译：在各种实施例中，多点控制单元（MCU）或其他视频会议设备（例如，端点）可以生成包括两个或多个视频会议端点的视频图像的视频帧。然后可以将视频帧发送到可以接收视频帧并将两个或更多个视频图像分离成单独的视频图像的另一个视频会议设备。在一些实施例中，可以使用例如与视频帧一起发送的元数据将视频帧分离成其单独的图像。元数据可以包括视频图像标识符和位置信息（例如视频帧中的坐标）。在一些实施例中，可以将分离的视频图像提供给可以将分离的视频图像复合到例如新布局的合成器。

摘要： Methods for authenticating a person to participant in a videoconference based on facial imaging, fingerprint imaging, other biometric information, passwords, and physical mediums are described. Identity information for the potential participant may be received, and a recognition algorithm may be performed to determine whether the received identity information for the potential participant matches pre-stored identity information for a first person, e.g., where the potential videoconferencing participant claims to be a specific person. If the recognition algorithm determines a match, the potential videoconferencing participant may be authenticated to participate in the videoconference.

摘要： A system and method for detecting local motion between image frames are presented. Each image frame may include a plurality of pixels. A first image frame and a second image frame may be received. Values of a first plurality of pixels at first pixel locations of the first image frame may be read. Values of a second plurality of pixels at second pixel locations of the second image frame may be read. The first pixel locations of the first image frame may correspond to the second pixel locations of the second image frame. A first delta function, based on differences between pixel values between the first and second image frames, may be calculated to produce a first output. The first output may be compared to a first one or more thresholds. It may be determined whether local motion has occurred in the second image frame based on said comparing.

摘要： In various embodiments, a speakerphone may comprise multiple (e.g., 16) microphones placed in a circular array around a central speaker. The microphones may be mounted vertically in the speakerphone with their respective diaphragms substantially parallel to the top surface of the speakerphone. The centrally mounted speaker may be coupled to a stiff internal speaker enclosure. The speaker enclosure may be made of a stiff, heavy material (e.g., a dense plastic) to prevent the speaker vibrations from excessively vibrating the speakerphone enclosure (which may affect the microphones). The speaker enclosure may also include a raised rim and ridges to increase its stiffness.
摘要翻译：在各种实施例中，扬声器电话可以包括围绕中央扬声器放置在圆形阵列中的多个（例如，16个）麦克风。麦克风可以垂直地安装在扬声器电话中，其各自的隔膜基本上平行于扬声器电话的顶面。中央安装的扬声器可以耦合到刚性的内部扬声器外壳。扬声器外壳可以由硬的重的材料（例如致密的塑料）制成，以防止扬声器振动使扬声器电话机壳体（可能影响麦克风）过度振动。扬声器外壳还可以包括凸起的边缘和脊以增加其刚度。
