On the content list, licensing equipment ID information and nickname information corresponding thereto are displaced on a content to a content basis, therefore making it possible to check with the nickname which electronic music device including an owned machine licenses each of the contents to be used (the condition of licensing the content to be used). On the content list, an owned machine license mark SM (a reference mark) is put down on an owned machine ID out of licensing equipment IDs for the contents, therefore making it possible to distinguish the owned machine ID from other licensing equipment IDs and check the condition of licensing the content to be used. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
