Abstract: PURPOSE:To effectively perform a series of encoding process of data row even if random data number are input by encoding input first data by encoding means, and externally outputting at least partial data of the encoded result. CONSTITUTION:When a data row is input, whether the number of bytes of the data row becomes integer number times of the number of unit byte to be encoded or not is judged. Whether the following data row exists or not is judged, and if next data row exists, the data row input this time is encoded, and remaining data tow is added to next data row. This is sequentially continued, and the final result of the encoded data is externally output while encoding the data row. Thus, a series of data rows can be effectively encoded even if random data number are input without limit of the number of unit bytes to be encoded in a device.
