PROBLEM TO BE SOLVED: To eliminate the need for transfer even when data possessed by a reception side is similar.SOLUTION: A transmission side transmits a feature quantity of first data and a restoration byte sequence for error correction. A reception side specifies second data having a feature quantity in a range similar to the received feature quantity among already possessed data, applies error correction processing using the received restoration byte sequence, and stores it as the first data. Even when the amount of data is several kilobytes, the amount of each of the feature quantity and the restoration byte sequence is at most several tens of bytes, so that a network load is small. |
