Abstract
We propose a novel system that can real-time capture and compress the full screen of PC into a video clip. It is real-time in that it can capture to 30 frames per second under the resolution of 1600 /spl times/ 1200 with true color. One application of this system is to produce a digital presentation clip for instruction or tutorial. Moreover, as the video clips can be streamed over Internet or intranet, they can be used for remote education or training. We believe this approach is clearer and more efficient than conventional text manual or handbook. As our system only captures the differences of successive snapshots instead of every single screen, it is more efficient and produces more compact clips than other existing systems. In addition, the compression algorithm adopted in our system is also described.
