Abstract: 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.

Abstract: A conferencing peripheral for use with a mobile device or laptop or desktop computer can include one or more projectors, cameras, microphones, and speakers. Such a device can work with the mobile device to provide a higher quality conferencing experience than has been provided to date by projecting a substantially full size, high resolution, image of conference participants onto a screen or wall and by providing microphones, speakers, and sufficient audio processing to provide high fidelity audio as part of the conferencing experience. The peripheral may be configured to use the voice and/or data network of the mobile device or may include its own internal network interface.

Abstract: 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.

Abstract: A videoconference multipoint control unit (MCU) automatically generates display layouts for videoconference endpoints. Display layouts are generated based on attributes associated with video streams received from the endpoints and display configuration information of the endpoints. An endpoint can include one or more attributes in each outgoing stream. Attributes can be assigned based on video streams' role, content, camera source, etc. Display layouts can be regenerated if one or more attributes change. A mixer can generate video streams to be displayed at the endpoints based on the display layout.

Abstract: Disclosed herein are methods and systems for providing continuous presence video stream in a cascading video conference, i.e., a video conference that is conducted over more than one MCU. A cascading continuous presence composition controller (CCCC) selects which endpoints from among all of the endpoints participating in the conference should be displayed in the layout, regardless of which endpoints are associated with which MCU. The CCCC can be resident on one of the MCUs, resident on a cascading conference server, or can be distributed among all of the MCUs involved in a cascading conference.

Abstract: Noise suppression systems and methods suppress far field noise in a microphone signal. A telephony system includes a main microphone and a reference microphone. In one example, the main microphone and the reference microphone can be located in the same device. In another example, the main microphone and the reference microphone can be located in two separate devices. A DSP can use the reference microphone signal to carry out suppression of far field noise in the main microphone signal. In one approach the DSP can determine an estimate of far field noise in the main microphone signal based on a noise estimate of the reference microphone signal and a reference and main microphone coupling estimate, and then subtract the far field noise estimate from the main microphone signal. Alternatively, the DSP can suppress the main microphone signal if it determines that a local talker is inactive.
