Abstract
A method for encoding compressed graphics video information and decoding such information. The method consists of enriching the video information in zeros through shifting and Exclusive ORing video image with itself. A number of methods are attempted in the shifting and Exclusive ORing process in order to determine the method which yields the optimum zero enriched image. The zero enriched image is then encoded and the encoded information stored. Upon retrieval, the information is decoded and an Exclusive OR and shifting process is done to obtain the original video information.
