Abstract
Usage rights to digital content are dynamically assigned. Various dynamic conditions are monitored and the usage rights are adjusted in a predetermined manner based on the status of dynamic conditions. The dynamic conditions include the time of day, the load on a server or network, or the like. The resolution of an image can be determined based on the conditions and the image can be rendered using subband decomposition techniques to permit variable resolution images to be constructed on the fly.
