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： 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： In a system and method of conducting a videoconference, a videoconferencing unit detects an activation related to a presentation device at a near-end of the videoconference. The unit stores a current orientation of at least one camera and directs the at least one camera at the presentation device. At this point, the unit begins outputting to a far-end at least one of (i) video captured of the presentation device with the at least one directed camera and (ii) content displayed with the presentation device. At some point, the unit detects a deactivation related to the presentation device at the near-end and then redirects the at least one camera to the stored orientation so the videoconference can proceed as before.

摘要： A videoconferencing system includes a first videoconferencing unit coupled to a network and associated with a first e-mail address. The first videoconferencing unit receives a second e-mail address and automatically sends a request e-mail requesting connection information to the second e-mail address. A second videoconferencing unit is coupled to the network and is associated with the second e-mail address. The second videoconferencing unit receives the request e-mail and automatically returns a response e-mail including connection information to the first e-mail address. The first videoconferencing unit receives the response e-mail and automatically obtains the connection information from the response e-mail. Using the 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.
