Abstract
Received sequentially encoded image data is converted into hierarchically encoded data having a resolution different from the sequentially encoded image data, and the converted encoded data is decoded with reference to an image of another layer. Received image data is divided into a plurality of grounds of data, and the divided grounds of data are stored. The same processing is performed on the divided data to obtain hierarchically encoded data, and obtained decoded image data is displayed.
