Abstract: Systems, methods, and apparatus for projecting an estimated direction of arrival of sound onto a plane that does not include the estimated direction are described.

Abstract: The present invention is a portable camera and lighting unit for standalone use in videography to create a high-resolution well-illuminated video feed from a vast array of camera angles and positions, the illumination source always inherently tracking with the camera. The unit may also be used as a satellite in combination with a primary video conferencing and production station (VVPR) for multi-camera production and teleconferencing capabilities. The portable camera and lighting unit includes a portable base, a mast extending upward from the base, and an articulating boom that is fully-pivotable and extendable. A remote control Pan-Tilt-Zoom camera is mounted at the end of the boom for overhead images of healthcare procedures, and an adjustable beam light source is mounted directly on the camera for lighting.

Abstract: A video card capable of being mounted in an information processing apparatus so as to enable suitable performance of a television conference system etc., wherein video data fetched into a video card from a camera by a capture operation is recorded in the first region of a DRAM and encoded at a signal processing unit. The encoded video data is recorded in the second region of the DRAM, sequentially transferred to a main memory of a notebook type PC, and transmitted to a network via a communication I/F card. The video data received from the network is stored once in the main memory, transferred to the fourth region of the DRAM of the video card, decoded at the signal processing unit, and recorded in the third region of the DRAM. Immediately before the next capture operation, the video data which was fetched into the first region of the DRAM before this and the received video data which has been recorded in the third region are displayed on a display via a VGA controller.
