Progressive transmission of multimedia is an important application in multimedia communications. We employ reversible data hiding for protecting the copyright of progressively transmitted images. We consider carefully altering the luminance differences between base and enhancement layers in progressive transmission, and obtain similar qualities of output images with enhanced amount of capacity. Simulation results demonstrate the superiority over existing schemes.
