Abstract: A system and method for manipulating images in a videoconferencing session provides users with a 3-D-like view of one or more presented sites, without the need for 3-D equipment. A plurality of cameras may record a room at a transmitting endpoint, and the receiving endpoint may select one of the received video streams based upon a point of view of a conferee at the receiving endpoint. The conferee at the receiving endpoint will thus experience a 3-D-like view of the presented site.

Abstract translation: 用于在视频会议会话中操纵图像的系统和方法为用户提供一个或多个呈现的站点的3D样式视图，而不需要3-D设备。 多个相机可以在发送端点处记录房间，并且接收端点可以基于在接收端点处的与会者的观点来选择所接收的视频流中的一个。 因此，接收端点的与会者将会体会到呈现站点的3-D状视图。

Abstract: A camera tracking system includes a controllable camera, an array of microphones, and a controller. The microphones are positioned adjacent the controllable camera and are at least responsive to ultrasound emitted from a source. The microphones may additionally be capable of responding to sound in the audible spectrum. The controller receives ultrasound signals communicated from the microphones in response to ultrasound emitted from the source and processes the ultrasound signals to determine an at least approximate location of the source. Then, the controller sends one or more command signals to the controllable camera to direct at least approximately at the determined location of the source. The camera tracking system tracks the source as it moves and continues to emit ultrasound. The source can be an emitter pack having one or more ultrasonic transducers that produce tones that sweep form about 24-kHz to about 40-kHz.

Abstract translation: 相机跟踪系统包括可控相机，麦克风阵列和控制器。 麦克风位于可控照相机附近，并且至少响应于从源发出的超声波。 麦克风可以另外能够响应可听频谱中的声音。 控制器响应于从源发射的超声波接收从麦克风传送的超声信号，并处理超声信号以确定源的至少近似位置。 然后，控制器将一个或多个命令信号发送到可控照相机，以至少大致指向源的确定位置。 相机跟踪系统在移动时跟踪源，并继续发射超声波。 源可以是具有一个或多个超声波换能器的发射器组，其产生大约24kHz至大约40kHz的扫描的音调。

Abstract: A computer program of the type commonly known as a “wizard” is disclosed that initializes user interface software for controlling an audio conferencing device. The wizard allows the desired audio inputs (e.g., microphone, telephones, etc.) and audio outputs (speakers, recording devices, etc.) to be chosen by an audio system administrator. Thereafter, the wizard allows an audio conferencing device (or devices) to be chosen by the administrator, or allows such a device(s) to be optimally chosen dependent upon the chosen inputs and outputs. The wizard then maps the inputs and outputs to the input and output ports on the audio conferencing device. When the administrator finishes the wizard, the wizard computes the mapping parameters and other audio-optimizing parameters for the selected inputs and outputs. These parameters are then loaded into the user interface software automatically.

Abstract translation: 公开了通常称为“向导”的计算机程序，其初始化用于控制音频会议设备的用户界面软件。 该向导允许由音频系统管理员选择所需的音频输入（例如，麦克风，电话等）和音频输出（扬声器，记录设备等）。 此后，向导允许管理员选择音频会议设备（或设备），或者允许根据所选择的输入和输出来最优地选择这样的设备。 然后，向导将输入和输出映射到音频会议设备的输入和输出端口。 当管理员完成向导时，向导将计算所选输入和输出的映射参数和其他音频优化参数。 然后将这些参数自动加载到用户界面软件中。

Abstract: A network adapter detection is used to establish a videoconference between a videoconferencing unit and a remote endpoint. Information about a plurality of network adapters available for the videoconferencing application is obtained, and one or more test messages are sent to at least one open source server using each of one or more of the obtained network adapters. The videoconferencing unit than awaits a response to each of the one or more sent test messages from the at least one open source server. If a response is received, the videoconferencing application uses the network adapter that received the response to establish a videoconference connection with the remote endpoint.

Abstract: 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.
