PROBLEM TO BE SOLVED: To provide an information communication system, an information transmission apparatus, and an information transmission method with high burst error immunity by retransmitting information at an interval of a short delay time. SOLUTION: The information communication system comprises the information transmission apparatus and an information receiver, and the information transmission apparatus uses an RTP transmission section 11a to transmit a plurality of kinds of information items in a form of RTP packets. An RTP reception section 12b of the information receiver receives the RTP packets and transmits the accumulated numbers of missing RTP packets by each of a plurality of kinds of the information items to the information transmission apparatus at a prescribed time interval. An RTCP reception section 12c of the information transmission apparatus obtains a time zone in common to time zones when the RTP packets of a plurality of kinds of the information items are missing, obtains a maximum value of the length of burst errors from the obtained time zone and stores a time required to transmit the maximum value to a maximum burst error time storage section 13 as a maximum burst error time 13a. A delay section 11b of the information transmission apparatus retransmits a plurality of kinds of the information items after an interval equivalent to a delay time being the maximum burst error time 13a.
