摘要： An overhead microphone assembly using multiple unidirectional microphone elements. The microphone assembly is installed overhead, generally above all the desired sound sources and below the undesired sound sources. The signals from these multiple microphone elements are fed into a microphone steering processor which can mix and gate the signals to ensure the best signal/noise ratio. The steering processor may also track the sound source dynamically when such tracking (source locating) is desired. The resulting audio signal from the steering processor may be further processed, such as echo canceling, noise reduction and automatic gain control.

摘要： A conference link between devices in teleconference system at one site is disclosed. The linked devices include video conference units, speakerphones or stand-alone loudspeakers. Audio data can be transmitted through the conference link between devices. Audio data processing can be performed in either a video conference unit or a speakerphone. The microphones and loudspeakers in the video conference unit may be eliminated. The microphones and loudspeakers in the speakerphone are used. Other data, for example directories of dialing information, may also be transmitted through the conference link and the data processing may be allocated among processors in devices connected by conference links. The conference link may be wired or wireless, analog or digital. The devices may be linked by conference link in parallel or series. A dialing program can adapt the dialing stream with the locations of the near end site and the dialed far end site. The dialing program can automatically select a mutually supported network or protocol to establish a connection between two sites.

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： 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.
摘要翻译：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。

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。
