PROBLEM TO BE SOLVED: To make it possible to optimally transmit/receive the gradated data according the capacity of a receiving side. SOLUTION: A gradated data read-in part 11 of a transmitting side reads in plural gradated data of different gradated number related to the same subject. A data transmission part 16 transmits plural read-in gradated data, and a gradated data receiving part 21 of the receiving side receives the gradated data, and an optimum gradation decision part 25 decides the optimum gradated number capable of being processed by the output subject as the optimum gradated number. A gradated data analysis part 24 analyses the gradated number of the received gradated data, and an extraction gradated data decision part 26 retrieves the gradated data having the optimum gradated number from the received gradated data based on the analysed result by the gradated data analysis part 24, and decides as the extraction gradated data. A gradated data extraction part 27 extracts the decided extraction gradated data, and a gradated data output part 23 outputs the gradated data to the output subject. |
