Abstract: A system and method for acoustic source location using a horizontal and vertical microphone array. Tilt sensors are provided within each array to allow full determination of the tilt of each array. Based on the acoustic source location results, an image capture device may be maneuvered to focus in the direction of the acoustic source location.

Abstract: A novel universal bridge (UB) can handle and conduct multimedia multipoint conferences between a plurality of MREs and LEPs without using an MRM, an MCU and a gateway. Further, a UB can be configured to allocate and release resources dynamically according to the current needs of each conferee and the session.

Abstract: A method includes receiving, at a conference endpoint, video captured using a wide angle lens. The method further includes selecting a view region in a frame of the video. The method further includes selectively applying, based on a size of the view region, deformation correction or distortion correction to the view region to generate a corrected video frame. The method further includes transmitting the corrected video frame to a remote endpoint.

Abstract: A method includes generating first audio data based on sound detected by a sound sensor at a first time. The method further includes transmitting, via one or more communication interfaces, the first audio data to another device during a communication session based on a determination that the sound sensor is unmuted with respect to the communication session at the first time. The method further includes generating second audio data based on sound detected by the sound sensor at a second time. The method further includes refraining from transmitting the second audio data to the other device during the communication session based on a determination that the sound sensor is muted with respect to the communication session at the second time. The method further includes initiating a natural language processing operation on the second audio data based on detecting a wake phrase in the second audio data.

Abstract: Systems and methods for collaboratively controlling the display of information across multiple displays is disclosed. A plurality of electronic devices linked to a plurality of co-located display devices are accessed. At least one of the plurality of electronic devices is a master electronic device. Different users can select and transfer content elements from the set displayed on the master display device to the remainder of display devices, such that the selected and transferred content elements advance in order across the remainder of display devices. Users can select individual content elements from a device under their control for display by one or more display devices without the need to transfer an entire document or file from which the content element is taken. Once a content element is so displayed, other currently displayed content elements are advanced in a logical manner, or removed from display.

Abstract: A videoconference apparatus and method coordinates a stationary view obtained with a stationary camera to an adjustable view obtained with an adjustable camera. The stationary camera can be a web camera, while the adjustable camera can be a pan-tilt-zoom camera. As the stationary camera obtains video, participants are detected and localized by establishing a static perimeter around a participant in which no motion is detected. Thereafter, if no motion is detected in the perimeter, any personage objects such as head, face, or shoulders which are detected in the region bounded by the perimeter are determined to correspond to the participant.

Abstract: Traditional audio feedback elimination systems may attempt to reduce the effect of the audio feedback by simply scaling down the audio volume of the signal frequencies that are prone to howling. Other traditional feedback elimination systems may also employ adaptive notch filtering to detect and “notch” the so-called “singing” or “howling” frequencies as they occur in real-time. Such devices may typically have several knobs and buttons needing tuning, for example: the number of adaptive parametric equalizers (PEQs) versus fixed PEQs; attack and decay timers; and/or PEQ bandwidth. Rather than removing the singing frequencies with PEQs, the devices described herein attempt to holistically model the feedback audio and then remove the entire feedback signal. Two advantages of the devices described herein are: 1.) the system can operate at a much larger loop-gain (and hence with a much higher loudspeaker volume); and 2) setup is greatly simplified (i.e., no tuning knobs or buttons).

Abstract: A videoconferencing system has a videoconferencing unit that use portable devices as peripherals for the system. The portable devices obtain near-end audio and send the audio to the videoconferencing unit via a wireless connection. In turn, the videoconferencing unit sends the near-end audio from the loudest portable device along with near-end video to the far-end. The portable devices can control the videoconferencing unit and can initially establish the videoconference by connecting with the far-end and then transferring operations to the videoconferencing unit. To deal with acoustic coupling between the unit's loudspeaker and the portable device's microphone, the unit uses an echo canceller that is compensated for differences in the clocks used in the A/D and D/A converters of the loudspeaker and microphone.

Abstract: A technique of motion estimation in video compression is described, the technique including: determining, in one or more reference frames of a video picture, the best full-pixel motion vector F for a block in a current frame of the video picture, wherein m and n are signed numbers and integer multiples of the distance between two adjacent full-pixels; selecting the best half-pixel motion vector candidates from a set of half-pixel motion vectors based on the best full-pixel motion vector; determining the best half-pixel motion vector H; selecting the best quarter-pixel motion vector candidates from a set of quarter-pixel motion vectors based on the best full-pixel motion vector and the best half-pixel motion vector; determining the best quarter-pixel motion vector Q; and determining the best motion vector for the block as BMV.
