1427 results about "Video capture" patented technology

Video capture is the process of converting an analog video signal—such as that produced by a video camera, DVD player, or television tuner—to digital video and sending it to local storage or to external circuitry. The resulting digital data are referred to as a digital video stream, or more often, simply video stream. Depending on the application, a video stream may be recorded as computer files, or sent to a video display, or both.
