<p>A transmission side has first through Nth moving picture encoder/senders (101-1 through 101-N) for compressing moving picture frames into N encoded data and sending the encoded data. Second through Nth moving picture encoder/senders (101-2 through 101-N) compress frames encoded by the first moving picture encoder/sender (101-1) at compression ratios, which are higher than that of the first encoder/sender, using interframe prediction parameters and residual image data which are obtained in compression performed by the first moving picture encoder/sender (101-1) or a reference frame used in compression by the first moving picture encoder/sender (101-1). Each one of reception sides selects the encoded data having the lowest compression ratio and high image quality with frame-by-frame-selection or packet-by-packet-selection from the encoded data received without error and decodes the selected encoded data. <IMAGE></p> |
