Abstract
A distribution server 103 distributes a content via a network, and a KIOSK terminal 105 receives the content via the network and records the content in an SD memory card 100. A customer device 111 receives a content via the SD memory card 100, checks out the content and records a copy on a recording medium. SD-Audio players 122 to 124 receive a copy of the content and play back the copy. Here, the KIOSK terminal 105 records a Usage Rule that certifies the right to control recording of content on the SD memory card 100. Move Control Information showing the number of times that moving of rights is permitted is set in the Usage Rule.
