PROBLEM TO BE SOLVED: To obtain a broadcasting type data which provide system for efficiently acquiring data. SOLUTION: A server 11 is provided with a function for dividing broadcasting data, to which a broadcasting header is added, while containing attribute information such as the destination, into plural packets and also for performing broadcasting for the unit of a packet based on a user datagram protocol(UDP), by adding the packet header containing relative position information such as a sequential number, for example, in the broadcasting data of a division source to respective packets. Then, on the side of a client 14 for receiving the broadcasting data from the server 11, a function is provided for discriminating whether the broadcasting data are required for the client 14 or not from the packet header of a leading packet among the plural packets, for abandoning the packets at a time point when the data are not required, and also for performing the receiving processing of only the relevant packet from the sequential number of the packet header, when there is an extinguished packet. |
