PROBLEM TO BE SOLVED: To simplify the configuration of each sending means by providing a means to control a desired sending means so that only the desired sending means among sending means may send 2nd data based on 2nd identification information. SOLUTION: A data sending part 20 produces download packet data D18 to which corresponding identification information is added based on download data 17 and gives it to each multiplexer 18A to 18N through a distributor 21. Any of the multiplexers 18A... which is designated through an inputting part 23 or only the multiplexer 18N among the multiplexers 18A to 18N is made to select and to output each download packet data D18 based on the identification information under the control of a multiplexer controller 23. Further, the data D18 is prevented from being sent from each multiplexer 18... except the multiplexer 18A... or the multiplexer 18N, or the multiplexer 18N based on the identification information. |
