ABSTRACT:
The present invention divides a video frame into a series of smaller and smaller quadrants until reaching a single pixel size. By issuing a series of commands, a logical cursor moves within the quadrants to evaluate the frame for changes from the previous frame. Upon detecting a color change, the exact location (identified by a level and a quadrant thereof) is encoded along with a value for the change. As a result of the novel approach disclosed herein, there may be significant storage savings over the prior art.
