Patent ID: 7668091

Claim:
An information transmission method for an information transmission apparatus including a processing unit to transmit information in units of a particular set of packets to a plurality of receiving terminals, said method comprising: a necessity-of-adjustment determining step of determining with the processing unit whether the receiving terminal specified as the destination of the set of packets is a receiving terminal which needs the adjustment of inter-packet transmission intervals, on the basis of information described in a receiving terminal information table including information indicating the type and the processing capacity of the receiving terminal the inter-packet transmission intervals start at the completion of transmission of a packet and end at the beginning of transmission of a subsequent packet; a transmission interval adjusting step, of adjusting some packet-to-packet inter-packet transmission intervals using an interval adjusting device, at which some of the sets of packets are to be transmitted, and not adjusting other packet-to-packet inter-packet transmission intervals at which other sets of packets are to be transmitted continuously, depending on the processing capacity of the receiving terminal indicated by the information stored in the table; and a transmission step, of transmitting the set of packets, packet by packet, to the receiving terminals (i) at the inter-packet transmission intervals adjusted in the transmission interval adjusting step or continuously, wherein, when it is determined, in the necessity-of-adjustment determining step, that the receiving terminal specified as the destination of the set of packets is a receiving terminal which needs the adjustment of inter-packet transmission intervals, execution of the transmission interval adjusting step is accomplished using the interval adjusting device and when it is determined, in the necessity-of-adjustment determining step, that the receiving terminal specified as the destination of the set of packets is a receiving terminal which does not need the adjustment of inter-packet transmission intervals, the interval adjusting device is bypassed.
