摘要： A videoconferencing system allows host users to personalize virtual meeting rooms (VMR). A multipoint control unit (MCU) generates VMRs using associated VMR configuration parameters, which include personal VMR parameters specified by the host user, and admin VMR parameters specified by an administrator of the videoconferencing system. The host user can connect to a server at the MCU to request a list of personal VMR parameters, for which the host user can specify values. The server can receive and store the specified values for the personal parameters. The MCU can combine the values of personal VMR parameters with values of admin VMR parameters in generating VMR configuration.

摘要： A videoconferencing system provides sharing program content during a videoconferencing session. A graphical user interface (GUI) allows participants to select a program to be shared and participants to share the selected program with. A scheduler communicates with the videoconferencing systems of the participants to tune or configure them to receive the selected shared program content at a scheduled time. The scheduler also communicates with a multipoint control unit (MCU) for initiating a videoconferencing session between the participants. The videoconferencing system combines mixed video streams received from the MCU with the program stream of the selected shared program and displays the combined stream on the display device. The scheduler can be located at a program service provider or at the initiating participant's videoconferencing system.
摘要翻译：视频会议系统在视频会议会话期间提供共享节目内容。图形用户界面（GUI）允许参与者选择要共享的节目和参与者共享所选择的节目。调度器与参与者的视频会议系统通信以调整或配置它们以在预定的时间接收所选择的共享节目内容。调度器还与多点控制单元（MCU）进行通信，用于启动参与者之间的视频会议会话。视频会议系统将从MCU接收的混合视频流与所选择的共享程序的节目流相结合，并将显示装置上的组合流显示出来。调度程序可以位于程序服务提供者处或发起参与者的视频会议系统处。

摘要： A master device (e.g., a laptop) controls a videoconference connection with a far-end and acts as a controller for slave devices in a group. The master establishes the connection with the far-end using a wide area network and connects with the slaves using a Wi-Fi connection of a local area connection. To connect to the slaves, the master outputs an ultrasonic beacon encoding the master's address in the local network. The beacon also allows differences in the various clocks to be handled during audio processing. During the videoconference, the master outputs far-end audio to a loudspeaker and sends the far-end video to its display and to the slaves. Each device captures audio/video with its microphone and camera. The master determines which captured audio is a dominant talker's and may only send that audio to the far-end. The video associated with the dominant talker's device may also be sent to the far-end.
摘要翻译：主设备（例如，笔记本电脑）控制与远端的视频会议连接，并且用作组中的从设备的控制器。主机使用广域网建立与远端的连接，并使用局域网连接的Wi-Fi连接与从站进行连接。要连接到从站，主站输出编码本地网络主站地址的超声波信标。信标还允许在音频处理期间处理各种时钟的差异。在视频会议期间，主机将远端音频输出到扬声器，并将远端视频发送到其显示器和从站。每个设备用麦克风和相机捕获音频/视频。主人确定哪个捕获的音频是主要的说话者，并且只能将该音频发送到远端。与主要讲话者的设备相关的视频也可能被发送到远端。

摘要： Systems and methods are disclosed to identify and generate keyword searches in real-time or near real-time for active participants in an on-going Audio, Video and Data Collaboration meeting (also referred to as “Unified Communications and Collaboration” or UCC). In one embodiment, multiple input sources are screened to detect text data and generate search strings from the deciphered keywords. Keywords are deciphered from presentation materials and other forms of data input to a UCC (e.g., documents, video, and audio). Keywords and generated search strings can then be presented to one or more participants for selection (e.g., hyperlink) to retrieve and present supporting material relative to a topic of discussion or point of interest in the UCC. Alternatively, recorded content can be search during or prior to playback to allow incorporation of disclosed embodiments and concepts.
摘要翻译：公开了系统和方法，以便在正在进行的音频，视频和数据协作会议（也称为“统一通信和协作”或UCC）中为实时参与者实时或接近实时地识别和生成关键词搜索。在一个实施例中，屏蔽多个输入源以检测文本数据并从解密的关键字生成搜索串。关键字从演示材料和其他形式的数据输入到UCC（例如，文档，视频和音频）被解密。然后可以将关键字和生成的搜索字符串呈现给一个或多个参与者以进行选择（例如，超链接）以相对于UCC中的讨论主题或兴趣点来检索和呈现支持材料。或者，记录的内容可以在播放期间或之前进行搜索以允许所公开的实施例和概念的结合。

摘要： In videoconference camera selection, audio inputs associated with cameras for a videoconference are each processed into first and second audio energies respectively for first and second frequency ranges. The selection then determines which of the audio inputs has a greatest ratio of the first audio energy to the second audio energy and selects the associated camera view for outputting video for the videoconference. The selection can also process video inputs from the cameras either alone or in combination with the audio processing. Either way, the selection processes each of the video inputs for at least one facial characteristic and determines which of the video inputs has a greatest likelihood of framing a human face. In the end, the selection selects the associated camera view for outputting video for the videoconference based at least in part on this video-based determination.
摘要翻译：在视频会议相机选择中，与用于视频会议的相机相关联的音频输入分别被分别用于第一和第二频率范围的第一和第二音频能量。然后，该选择确定哪个音频输入具有第一音频能量与第二音频能量的最大比率，并且选择用于输出用于视频会议的视频的相关联的摄像机视图。选择还可以单独处理来自摄像机的视频输入或与音频处理相结合。无论哪种方式，选择处理至少一个面部特征的每个视频输入，并且确定哪个视频输入具有构图人脸的最大可能性。最后，该选择至少部分地基于该基于视频的确定来选择用于输出用于视频会议的视频的相关联的摄像机视图。

摘要： 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.

摘要： A method for efficiently accessing pertinent information retrieved from a videoconferencing system call log. System call logs typically contain a chronological list of raw information pertaining to inbound and outbound videoconferencing calls. The method for efficiently accessing this chronological information is performed using input from the user at an endpoint to correlate and sort for display the information required at the current time. Videoconferencing systems typically are shared use or community type devices and the method of this disclosure allows for more user friendly access to pertinent information. Auto population of a speed dial list or associating a smart tag with the retrieved information is another possible feature to aid the end user. This method will allow a business to more efficiently use a limited number of videoconferencing systems amongst diverse groups of users with diverse calling needs.
