HIGH RESOLUTION DIGITAL SCREEN RECORDER AND METHOD |
摘要 |
<p>A machine independent high resolution digital screen recorder provides high quality video displays with manageable storage capacity and bandwidth. The screen recorder includes an analog to digital frame grabber for converting the high resolution video signal that modulates a video display into RGB sequences of digital frames. A video compression unit separates the high and low variance portions of the digital frames, encodes them with respective lossy and lossless compression algorithms and stores them in a mass storage device.</p> |
