Abstract: A system and method for high resolution video conferencing is shown and described. A transmitting station and a receiving station including video cameras or sensors, a plurality of microphones and speakers, video, audio and communication processing engines are disclosed. Video is processed and transferred through the system allowing for multiple video streams to be produced and audio is processed and transferred through the system allowing for sound to be played back with an indication of position in relation to the videoconferencing system.

Abstract: In accordance with the present invention, a system and method for computing a location of an acoustic source is disclosed. The method includes steps of processing a plurality of microphone signals in frequency space to search a plurality of candidate acoustic source locations for a maximum normalized signal energy. The method uses phase-delay look-up tables to efficiently determine phase delays for a given frequency bin number k based upon a candidate source location and a microphone location, thereby reducing system memory requirements. Furthermore, the method compares a maximum signal energy for each frequency bin number k with a threshold energy Et(k) to improve accuracy in locating the acoustic source.

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.
