Abstract:
1. An image communication method for sending an image from a transmitter to at least one receiver, said method comprising the steps of: in said transmitter: encoding said image in accordance with a hierarchical coding scheme to generate more than two layer data; performing error correction coding on each of at least two of said layer data including a lowermost of said layer data in accordance with an error correction coding scheme, wherein for all said layer data to which said error correction is applied, higher error correcting capabilities are given to lower layer data; and sending a plurality of said layer data including layer data subjected to said error correction coding to said receiver, and in each said receiver: correcting errors introduced on a transmission path into said layer data received from said transmitter in accordance with said error correction coding scheme; and decoding layer data acquired in a quality available for decoding to restore the image.
