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： 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： 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 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： 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.
