Abstract

A content data storage apparatus that enables content data on a plurality of client apparatuses to be individually updated according to the preferences or the like of users. Content data on a memory card is stored in association with client content management information for managing the content data and client content identification information for identifying the content data in management units. When client content identification information stored on a memory card connected to an input/output unit matches any storage content identification information stored on a hard disk, a control unit updates the content data of the memory card based on content data included in management units identified by this storage content identification information.

Claims

1. A content data storage apparatus for storing content data, and updating content data on a client apparatus based on the stored content data, comprising:

a storage content storage medium capable of storing plural groupings of content data in association with storage content management information for managing a set of the content data and storage content identification information for identifying the content data in management units;

an input/output unit that performs data input/output with the client apparatus; and

a control unit that updates the content data of the client apparatus, wherein the content data of the client apparatus is stored on the client apparatus in association with client content management information for managing the content data and client content identification information for identifying the content data in management units, and

the control unit acquires the client content identification information of content data in one or a plurality of management units specified for updating out of the content data of a client apparatus connected to the input/output unit, and, if storage content identification information matching the acquired client content identification information is stored in the storage content storage medium, updates the content data of the client apparatus based on content data included in management units identified by the storage content identification information that matches the client content identification information.

2. The content data storage apparatus according to claim 1, wherein

update information that includes the client content identification information of content data in one or a plurality of management units specified for updating out of the content data of a client apparatus is held in the client apparatus, and

the control unit acquires the client content identification information included in the update information from a client apparatus connected to the input/output unit, via the input/output unit.

3. The content data storage apparatus according to claim 1, further comprising an update information storage unit that stores update information that includes the client content identification information of content data in one or a plurality of management units specified for updating out of the content data of a client apparatus, and an identifier unique to the client apparatus using the content data, wherein

the control unit acquires the identifier of a client apparatus connected to the input/output unit from the client apparatus via the input/output unit, and acquires the client content identification information corresponding to the acquired identifier from the update information storage unit.

4. The content data storage apparatus according to claim 2, wherein the update information further includes an update condition of content data in one or a plurality of management units specified for updating, and

the control unit updates the content data of the client apparatus, based on content data included in management units identified by the storage content identification information that matches the client content identification information, and the update condition.

5. The content data storage apparatus according to claim 2, further comprising an operation input unit for allowing a user to set the update information.

6. The content data storage apparatus according to claim 1, wherein if content data in a plurality of management units is specified as content data for updating, the control unit updates the content data of the client apparatus, based on a sum set of content data in a plurality of management units identified by storage content identification information that matches the client content identification information of the content data in the plurality of management units.

7. The content data storage apparatus according to claim 1, wherein if content data in a plurality of management units is specified as content data for updating, the control unit updates the content data of the client apparatus, based on a product set of content data in a plurality of management units identified by storage content identification information that matches the client content identification information of the content data in the plurality of management units.

8. The content data storage apparatus according to claim 1, wherein if there is content data in the client content management information that is not included in the storage content management information and not stored in the storage content storage medium, the control unit maintains the content data without deletion from the client apparatus.

9. A content data update system comprising a client apparatus that uses content data, and a content data storage apparatus that updates the content data of the client apparatus based on stored content data, wherein

the content data storage apparatus includes:

a storage content storage medium capable of storing plural groupings of content data in association with storage content management information for managing a set of the content data and storage content identification information for identifying the content data in management units;

an input/output unit that performs data input/output with the client apparatus; and

a control unit that updates the content data of the client apparatus,

the client apparatus includes;

a client content storage medium that stores content data used by the client apparatus in association with client content management information for managing the content data and client content identification information for identifying the content data in management units, and

the control unit of the content data storage apparatus acquires the client content identification information of content data in one or a plurality of management units specified for updating out of the content data of a client apparatus connected to the input/output unit, and, if storage content identification information matching the acquired client content identification information is stored in the storage content storage medium, updates the content data of the client apparatus based on content data included in management units identified by the storage content identification information that matches the client content identification information.

10. A content data storage method for updating content data on a client apparatus that uses the content data, based on content data stored in a content data storage apparatus, comprising the steps of:

storing the content data used by the client apparatus on a client content storage medium of the client apparatus in association with client content management information for managing the content data and client content identification information for identifying the content data in management units;

storing plural groupings of content data on a storage content storage medium of the content data storage apparatus in association with storage content management information for managing a set of the content data and storage content identification information for identifying the content data in management units;

acquiring the client content identification information of content data in one or a plurality of management units specified for updating out of the content data of a client apparatus connected to the content data storage apparatus; and

updating, if storage content identification information matching the acquired client content identification information is stored in the storage content storage medium, the content data of the client apparatus based on content data included in management units identified by the storage content identification information that matches the client content identification information.
