摘要： A videoconferencing apparatus automatically tracks speakers in a room and dynamically switches between a controlled, people-view camera and a fixed, room-view camera. When no one is speaking, the apparatus shows the room view to the far-end. When there is a dominant speaker in the room, the apparatus directs the people-view camera at the dominant speaker and switches from the room-view camera to the people-view camera. When there is a new speaker in the room, the apparatus switches to the room-view camera first, directs the people-view camera at the new speaker, and then switches to the people-view camera directed at the new speaker. When there are two near-end speakers engaged in a conversation, the apparatus tracks and zooms-in the people-view camera so that both speakers are in view.
摘要翻译：视频会议设备自动跟踪房间中的扬声器，并在受控的人民摄像机和固定的室内摄像机之间动态切换。当没有人在说话的时候，设备会显示到远端的房间视图。当房间中有主导扬声器时，设备将人物摄像机引导到主扬声器，并从室内摄像机切换到人民摄像机。当房间里有一个新的扬声器时，设备首先切换到室内摄像机，将人物摄像机引导到新的扬声器，然后切换到指向新扬声器的人物摄像机。当有两个近端扬声器进行通话时，该设备将跟踪和放大人民摄像机，以便两个扬声器都在视野中。

摘要： A presentation device includes an embedded web server for transmitting images representative of presentation information to network-connected terminals concurrently with the display of such presentation information at the presentation site. The images may be viewed at the terminals by pointing a conventional web browser to a DNS name or IP address associated with the presentation device. Certain of the terminals may be given presenter privileges, wherein the users of the presenter terminals may control aspects of the presentation such as slide sequencing by engaging the appropriate controls displayed within the browser window. In this manner, presentations may be viewed and controlled remotely using a conventional browser interface.

摘要： A router of a network is configured to manage routing of packets based on executing applications. The network communicates packets of information between endpoints coupled to the network. Each packet is assigned to a traffic class based on the application associated with the packet. The router manages routing of received packets based on the traffic classes associated with the received packets. Accordingly, the router can determine routing priority, bandwidth, acknowledgment policy, and other routing management information based on the applications associated with received packets.

摘要： Audio from a near-end that has been acoustically coupled at the far-end and returned to the near-end unit is detected and suppressed at the near-end of a conference. First and second energy outputs for separate bands are determined for the near-end audio being sent from the near-end unit and for the far-end audio being received at the near-end unit. The near-end unit compares the first and second energy outputs to one another for each of the bands over a time delay range and detects the return of the sent near-end audio in the received far-end audio based on the comparison. The comparison can use a cross-correlation to find an estimated time delay used for further analysis of the near and far-end energies. The near-end unit suppresses any detected return by muting or reducing what far-end audio is output at its loudspeaker.
摘要翻译：来自远端的声耦合并返回到近端单元的近端的音频在会议的近端被检测和抑制。确定用于单独频带的第一和第二能量输出用于从近端单元发送的近端音频以及在近端单元处接收的远端音频。近端单元在时间延迟范围内针对每个频带将第一和第二能量输出彼此进行比较，并且基于该比较来检测所接收的远端音频中所发送的近端音频的返回。比较可以使用互相关来找到用于进一步分析近端和远端能量的估计时间延迟。近端单元通过静音抑制任何检测到的返回，或者减少在其扬声器处输出远端音频。

摘要： A router can process the data received from the local area network at a network protocol stack local to the router, while processing data received from the wide area network normally. The offloading of the stack processing from the source of the data to the router reduces the number of network hops that both packets based on the received data, and acknowledgements from the destination of the packets, must travel, thereby reducing communication latency. In addition, offloading the stack processing to the router can reduce the processing load at the data source. Further, the router can implement different quality of service or other processing protocols for the local area and wide area traffic.
摘要翻译：路由器可以在处理从广域网正常接收到的数据的同时，处理本地局域网的网络协议栈从局域网接收的数据。将堆栈处理从数据源卸载到路由器减少了基于接收到的数据的两个分组的网络跳数以及来自分组的目的地的确认必须行进，从而减少了通信延迟。此外，将堆栈处理卸载到路由器可以减少数据源处理负载。此外，路由器可以为本地区域和广域流量实现不同的服务质量或其他处理协议。

摘要： A multimedia distribution device includes an embedded stream encoder and an embedded stream server for encoding and transmitting, through utilization of streaming technology, audio and video content originating from a videoconference site and received through a network interface, to network-connected terminals. In situations in which the videoconference includes the presentation of slides or other content, the device may include a file conversion engine for converting the presentation content received through a data interface into a standard graphic image format, for synchronous distribution with the audio and video content stream. The multimedia content may be viewed in a multiple-window interface, wherein the audio and video content is presented by a streaming media player, and the presentation content is displayed in a separate window. Additionally, the interface may include an interactive text entry interface, through which the viewer may submit comments or questions to the conference presenters. In an operating architecture that includes a separate remote streaming server and a separate network server, a method of distributing content to a large number of viewers includes continuously transmitting the current and successive presentation images to the network server for caching, whereby the viewer web browser can request and locally cache the images prior to arrival of the associated audio and video content.
