A computer system executable method for use in transmitting digital video stream from a transmitting device to at least one receiving device. The method includes sending a first frame to at least one receiving device, comparing a first frame and a second frame for changed pixels, determining changed and unchanged pixels, coding said pixels to indicate the changed and unchanged pixels, transmitting the code to the at least one receiving device, and decoding the code and viewing the second frame on the at least one receiving device. The present invention also includes a computer system executable method for transmitting a digital video stream from a transmitting device to at least one receiving device where the method includes dividing a first frame and a second frame into corresponding sections, comparing each section for changed pixels, determining a changed pixel in one of the second frame sections, transmitting the section to said at least one receiving device, and integrating the section into the first frame. Also included is a combination of the methods.
