摘要:
A content sharing system is disclosed that can efficiently execute copyright management and can promote the degree of freedom and convenience in sharing of content within a legal range of private utilization. A group management server places a plurality of content processing apparatuses in terms of a unit of an owner into a group registration and issues a notification of a group ID of the group. A content recording apparatus adds a recorder ID thereof to production content produced thereby. Further, a content reproduction apparatus controls reproduction of content based on a recorder ID read out from content and a reproduction permission ID list. If the different processing apparatuses have the same group ID, the recorder ID can be added to the reproduction permission ID list.
摘要:
The present invention provides a content distribution server that allows the terminals owned by a same user to purchase content without repeating purchase processing once it has been executed only on one of these terminals. The content distribution server is made up of a content database storing the content identified by content ID in a plurality of files having different attributes and a user database storing the content IDs of the content purchased by the user identified by user ID. At the time of content purchase processing by a first terminal, this content distribution server registers the user ID of the first terminal in the user database. Subsequently, when a request for distribution comes from a second terminal, the content distribution server searches the user database of the second terminal for the content having an attribute available to the second terminal on the basis of the user ID of the second terminal without executing the purchase processing and distributes the retrieved content to the second terminal.
