摘要： A method includes receiving a plurality of audio signals, wherein the audio signals each include a plurality of packets containing voice data associated with conference participants. One or more of the audio signals is associated with a video signal and at least one of the audio signals is associated with a voice-only conference participant. The method further includes determining an activity metric for each of the plurality of audio signals, wherein the activity metric indicates a confidence value that the audio signal is associated with a conference participant that is currently speaking. The method also includes encoding, for each of the plurality of audio signals, one or more packets of the plurality of packets with the activity metric and sending the plurality of audio signals encoded with an activity metric to a conference bridge.
摘要翻译：一种方法包括接收多个音频信号，其中音频信号各自包括包含与会议参与者相关联的语音数据的多个分组。一个或多个音频信号与视频信号相关联，并且音频信号中的至少一个与只有话音的会议参与者相关联。所述方法还包括确定所述多个音频信号中的每一个的活动度量，其中所述活动度量指示所述音频信号与当前正在说话的会议参与者相关联的置信度值。该方法还包括为多个音频信号中的每一个编码具有活动度量的多个分组中的一个或多个分组，并将用活动度量编码的多个音频信号发送到会议桥。

摘要： A system for controlling a telepresence system includes a plurality of visual conferencing components operable to host a visual conference. The system also includes a controller coupled to the visual conferencing components. The system further includes an internet protocol (IP) phone coupled to the controller and operable to display a user interface comprising a plurality of options. The IP phone is also operable to receive input from a user and to relay the input to the controller. The controller is operable to control the visual conferencing components in accordance with the input from the IP phone.
摘要翻译：用于控制远程呈现系统的系统包括可操作以主持视觉会议的多个视觉会议组件。该系统还包括耦合到视觉会议组件的控制器。该系统还包括耦合到控制器并且可操作以显示包括多个选项的用户界面的因特网协议（IP）电话。 IP电话还可操作以从用户接收输入并将输入中继到控制器。控制器可操作以根据来自IP电话的输入来控制视觉会议组件。

摘要： A system and method for displaying participants in a videoconference between locations includes receiving a plurality of video signals from at least two cameras located at one or more remote sites. A display position is assigned for each video signal. The video signals are displayed on one or more displays. The display positions for the video signals maintain a fixed display position relative to each other video signal on the displays during the videoconference, and a number of displays is less than a number of cameras at the remote sites.
摘要翻译：用于在位置之间的视频会议中显示参与者的系统和方法包括从位于一个或多个远程站点的至少两个摄像机接收多个视频信号。显示位置被分配给每个视频信号。视频信号显示在一个或多个显示器上。在视频会议期间，视频信号的显示位置相对于显示器上的每个其他视频信号保持固定的显示位置，并且多个显示器少于远程站点处的相机数量。
