PROBLEM TO BE SOLVED: To enhance the reliability of transmission while preventing the increase of loads. SOLUTION: In this multiple address transmission system, a multiple address message preparation processing section 17 of a server 10 generates a multiple address message including a sequence number in a sequence number register 11, a server buildup time in a server buildup time register 12 and message information, broadcasts this multiple address message to clients 30. Upon the receipt of the multiple address message from the server 10, a missing detection processing section 35 of the client 30 discriminates coincidence/dissidence of the server buildup time in the multiple address message with that in a server buildup time register 32 and discriminates coincidence/dissidence of the sequence number in the multiple address message with that in a sequence number register 31, and detects the missing part of a past multiple address message when the processing section 35 detects the dissidence of at least either of them. |
