PROBLEM TO BE SOLVED: To provide a system allowing suppression of increase of a distribution load on a pod-caster distributing a pod-cast file even if popularity of the pod-cast file is heightened. SOLUTION: This pod-cast system has two kinds of servers of a Web server 10 and a distribution control file distribution server 60. The Web server 10 sends RSS pod-casting information including a prescribed URI that is a URI of a distribution control file (e.g. a torrent file or a grid file) needed for acquisition of a target file, configured with the target file as the pod-cast file to a user terminal 20. The distribution control file distribution server 60 receives access from the user terminal 20 according to the prescribed URI, and sends out the distribution control file to the user terminal 20. Thereby, the user terminal 20 performs the acquisition of the target file using a P2P technology based on the distribution control file. COPYRIGHT: (C)2009,JPO&INPIT
