ABSTRACT:
The present invention relates to a method for transmitting image data for superimposed images via wireless devices in a radio frequency communication system. The original image is transmitted via a communication channel to a receiving unit. The original image is then revised to form a revised image. The revised image is compared to the original image to determine the differences between the revised image and the original image. These differences comprise a difference image which is then transmitted to the receiving party. At the receiving end, the difference image is recombined with the previously-transmitted original image to reform the revised image. In a preferred embodiment, the original images and difference images are preferably decomposed and progressively transmitted to the receiving unit in response to image data requests from the receiving unit.
