摘要： A central directory system for a network of dial-up communication devices is described. In a preferred embodiment, the communication devices are videoconferencing devices. The system includes a directory management module coupled to the network and configured for importing and exporting directory information to and from a communication device. The directory information received by the management module can be grouped into address books by an access control module coupled to a database in which the address books can be stored. The access control module is further functional to manage access to the address books. Embodiments of the directory system provide systems and methods for providing intelligent dialing service to the dial-up communication device. A dialing algorithm determines a dialing sequence to connect communication devices through a network based on geographic dialing rules and information related to the requesting device.

摘要： The Graphical User Interface (GUI) of a videoconference terminal is provided with user-selectable icons which are associated by the user with various video signals. Textual labels for the various video signals may also be provided. This information may be exchanged with the “far end” participant in the video conference. During the videoconference participants may then simply select an icon to dynamically switch video feeds without having to remember by number the particular camera or other video signal associated with a desired video feed.

摘要： An automatic switching system and method for determining and effecting an optimal video display mode based on the interaction among participants in a conference or discussion is disclosed. The system includes a timer which continuously monitors the duration of signals received from each of a number of endpoints. The system further includes a signal switching processor which compares the signal durations to predefined parameters which define various display mode switching thresholds. The system reacts to the conversational interaction of endpoint participants by automatically switching the display mode of all endpoints between single-window, single speaker presentation mode, and multiple-window, multiple speaker discussion mode.

摘要： During a conference, a multipoint control unit (MCU) designates speaker and audience endpoints. The MCU receives votes from peripheral devices at the audience endpoints. The votes are aggregated and compared against a threshold by the MCU, and the MCU sends a notification or indication to the speaker endpoints if the threshold is exceeded. The votes have a lifespan over which they are valid. The votes may be weighted when there are targeted and non-targeted audience participants.

摘要： During a conference, a multipoint control unit (MCU) designates priority and non-priority endpoints. The MCU forms priority audio from the priority endpoint and sends that audio to the other endpoints at a normal level. However, the MCU forms non-priority audio from the non-priority endpoint and handles that audio based on whether the input audio from the priority endpoint is from speaking or not. If the priority endpoint's audio indicates a participant at that endpoint is speaking, then the MCU sends the non-priority audio to the other endpoints at a reduced level. Designation of which endpoint has priority can be based on which endpoint has a current duration of audio indicative of speech that is longer than other endpoints. Alternatively, the designation can be based on which endpoint is currently presenting content during the conference or based on a mix of speech audio and content presentation.
摘要翻译：在会议期间，多点控制单元（MCU）指定优先级和非优先级端点。 MCU从优先级端点构成优先音频，并将该音频发送到正常级别的其他端点。然而，MCU从非优先级终端形成非优先级音频，并且基于来自优先级端点的输入音频是否来自不同语言来处理该音频。如果优先级端点的音频指示该端点的参与者正在说话，则MCU以降低的级别将非优先级音频发送到其他端点。哪个端点具有优先权的指定可以基于哪个端点具有指示语音的当前持续时间长于其他端点。或者，该指定可以基于在会议期间当前呈现内容的哪个端点或者基于语音音频和内容呈现的混合。

摘要： 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.

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： A videoconferencing system includes a first videoconferencing unit coupled to a network and associated with a first instant messaging identity. The first videoconferencing unit obtains a second instant messaging identity and automatically sends a request instant message requesting videoconferencing connection information to the second instant messaging identity. A second videoconferencing unit is coupled to the network and is associated with the second instant messaging identity. The second videoconferencing unit receives the request instant message and automatically returns a response instant message including videoconferencing connection information to the first instant messaging identity. The first videoconferencing unit receives the response instant message and automatically obtains the videoconferencing connection information from the response instant message. Using the videoconferencing connection information, the first videoconferencing unit initiates a videoconference call with the second videoconference unit.

摘要： The system disclosed herein seeks to solve the problem of unnatural, dizzy camera motion when moving a camera between two preset positions, e.g., head and shoulder shots of two videoconference participants. Particularly, the system described herein attempts to mimic the camera movement that a professional camera operator would use in a professional video production. A preferred method of moving the camera between two positions is to first zoom out, away from the first position, pan across to the next position, then zoom in. This gives viewers of the camera content an idea of the spatial relationship between the two camera positions and also avoids the aesthetically undesirable effect of panning through irrelevant visual background at high zoom ratios. Disclosed herein is a technique of producing this desired behavior in the context of an automatically or semi-automatically controlled video camera, such as those used in conjunction with videoconferencing equipment.
摘要翻译：本文公开的系统旨在解决在两个预设位置（例如两个视频会议参与者的头部和肩部拍摄之间）移动相机时的不自然的，头晕的相机运动的问题。特别地，本文描述的系统尝试模拟专业摄像机操作者将在专业视频制作中使用的相机移动。在两个位置之间移动相机的优选方法是首先将它们从第一位置放大到远离下一个位置，然后放大。这给摄像机内容的观看者提供了两个摄像机之间的空间关系的想法并且还避免了在高变焦比下通过无关的视觉背景平移的美学上不利影响。本文公开了一种在自动或半自动控制的摄像机（例如与视频会议设备结合使用的摄像机）的上下文中产生该期望行为的技术。
