Abstract
A single base layer is formed by reducing information of input image data with at least a plurality of scalable factors, and a plurality of enhancement layers having information associated with a plurality of scalable factors are formed by using the base layer, thereby minimizing the amount of data to be transmitted and allowing the receiving side to arbitrarily select one of images with large information amounts based on various scalable factors. A system suited for image selection on the receiving side is also constructed.
