<P>PROBLEM TO BE SOLVED: To provide a distribution system, a server device, a terminal device, a service method, a terminal method and a program realizing them with a computer capable of reducing a load of a server and improving transmission efficiency of data when a plurality of terminals acquire the same data through a network. <P>SOLUTION: A server device 201 adds terminal identification names of terminal devices of message's transmission sources and a designated data identification name to a storage part 503 corresponding to request messages from a plurality of terminal devices. An acquisition part 504 acquires a data identification name stored in the storage part 503 without duplication, divides data into segments by the acquired data identification names and circularly transmits the segments to the terminal devices of transmission sources from a segment transmission part 505. When the terminal devices receiving the segments have acquired all the segments, they transmit a completion message to the server device 201 to finish the reception. <P>COPYRIGHT: (C)2012,JPO&INPIT |
