摘要： The system disclosed herein seeks to solve the problem of unnatural, dizzy camera motion when moving a camera between two preset positions, e.g., head and shoulder shots of two videoconference participants. Particularly, the system described herein attempts to mimic the camera movement that a professional camera operator would use in a professional video production. A preferred method of moving the camera between two positions is to first zoom out, away from the first position, pan across to the next position, then zoom in. This gives viewers of the camera content an idea of the spatial relationship between the two camera positions and also avoids the aesthetically undesirable effect of panning through irrelevant visual background at high zoom ratios. Disclosed herein is a technique of producing this desired behavior in the context of an automatically or semi-automatically controlled video camera, such as those used in conjunction with videoconferencing equipment.

摘要： Disclosed herein is a system and method for storing and transmitting a videoconference system name (identifier) in the languages of double byte character sets. Although described in terms of a videoconferencing system, the techniques described herein have applicability to various other systems that rely upon inter-language compatibility, including telephonic communication such as cell phones or IP phones, as well as various computer network applications in which computers having different default languages are in communication. In a preferred embodiment, the system identifier is stored in a text or ASCII format rather than native (binary) format. Additionally, a system employing a preferred embodiment of the teachings described herein allows a particular system to have multiple site names in multiple different languages. This allows such a system to interface and exchange identifier data with other systems having different language settings during a caller ID exchange.

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.

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.

摘要： A method and apparatus to be used for videoconferencing when the presentation is to include displays of documents or other visuals. A camera is focused on the document and detects when the document is being handled by the presenter. It automatically determines when to initially display the document, as well as when to update frames of data representing the document.
