Zusammenfassung:	PROBLEM TO BE SOLVED: To prevent the beginning of a broadcast from being cut, in receiving packets on an information terminal, when it takes time in Join processing of a router. SOLUTION: Broadcast packets are transmitted from a broadcasting server 1 via a network at a predetermined broadcast start time using RTPs (Real-time Transport Protocols) for a plurality of information terminals 3. Each of the information terminals 3 transmits an arrival time of a first broadcast packet in an answer-back signal. The broadcasting server 1 receives the answer-back signal, and calculates a correction time for correcting the broadcast start time from a plurality of arrival times. The broadcast start time is then corrected according to the correction time, and subsequent broadcasting is started. COPYRIGHT: (C)2011,JPO&INPIT
