Abstract

A content move system including a content-storing apparatus placed on an external bus, thereby performing a content-move operation reliably without losing a portion of the content, is provided. In a content move system for moving a content recorded on a storing part to a recording medium in a content-recording apparatus, a content-sending apparatus having the storing part, a content-recording apparatus, and a content-move controller for controlling the content-move operation conducted by the content-sending apparatus and the content-recording apparatus, are connected onto a 1394 bus. The content-move controller includes a move-source controlling part for managing the operation of the content-sending apparatus and a destination-controlling part for managing the operation of the content-recording apparatus. The content-sending apparatus includes a content-managing part for reading a content to be moved from the storing part and updating the stream information so as to be sent to the 1394 bus, and also a controller-monitoring part for monitoring the operation of the content-move controller.

2. The content move system according to claim 1, wherein the content-sending apparatus further comprises a destination-restricting part that passes a decryption key of the content to only an apparatus designated as a content-recording apparatus, thereby performing a destination-restricting process of restricting the content destination to the content-recording apparatus.

3. The content move system according to claim 1, wherein the move-source controlling part detects an operation state of the content-sending apparatus at the time of the content-move operation, and issues a record-ending request to the destination-controlling part when an abnormality in the operation state is detected;

and

the destination-controlling part detects an operation state of the content-recording apparatus at the time of the content-move operation, and issues a move-ending request to the move-source controlling part when an abnormality in the operation state is detected.

4. The content move system according to claim 1, wherein the controller-monitoring part issues a command for inquiring the operation state of the content-move controller, to the content-move controller.

5. The content move system according to claim 4, wherein the controller-monitoring part issues the command at a time interval of not longer than one minute.

6. The content move system according to claim 1, wherein the controller-monitoring part detects the operation state of the content-move controller, on the basis of whether a command access from the content-move controller to the content-sending apparatus is performed at a predetermined cycle.

7. The content move system according to claim 6, wherein the predetermined cycle is an interval of not longer than one minute.

8. The content move system according to claim 1, wherein the controller-monitoring part comprises a command-execution limiting part for executing only a command that agrees with a particular condition, and rejects commands except a command from the content-move controller during the content-move operation.

9. The content move system according to claim 8, wherein the controller-monitoring part comprises an apparatus-list acquiring part for acquiring information about connected apparatuses on the bus when bus initialization occurs during the content-move operation, and after the bus initialization, the controller-monitoring part executes a command only from the content-source controller in a case where the controller-monitoring part confirms that the content-move controller exists on the bus, on the basis of the connected apparatuses information acquired by the apparatus-list acquiring part.

10. The content move system according to claim 2, wherein the content-sending apparatus comprises a progress-notifying part for notifying the progress state of the destination-restricting process by the destination-restricting part, to the content-move controller.

11. The content move system according to claim 2, wherein the content-sending apparatus comprises a bus-monitoring part that suspends the content-move operation in the case where bus initialization occurs continuously after the destination-restricting process by the destination-restricting part is completed.

12. The content move system according to claim 11, wherein the time that the bus initialization-monitoring part requires for suspending the content-move operation from the first bus initialization operation among the continuous bus initialization operations is not longer than one minute.

13. The content move system according to claim 1, wherein the content-sending apparatus comprises a second destination-controlling part for managing the content-recording apparatus;

and

when detecting an operation abnormality in the content-move controller during the content-move operation, the controller-monitoring part activates the second destination-controlling part so as to perform the content-move operation continuously.

14. The content move system according to claim 1, wherein the content-move controller is packaged in a same hardware as the content-recording apparatus.

15. A content move system for moving a content recorded on a first recording medium to a second recording medium, the content move system comprising:

a content-sending apparatus for reading a content from the first recording medium, and

a content-recording apparatus for recording the content on the second recording medium

the content-sending apparatus and the content-recording apparatus are connected onto a same bus;

wherein

the content-sending apparatus comprises a content-managing part for reading a content to be moved from the first recording medium and updating the stream information of the content so as to be sent to the bus, and a data-broadcast generating part for changing information other than the content sent from the content-managing part into a data-broadcast stream and sending to the bus.

16. The content move system according to claim 15, wherein the content-sending apparatus comprises a move-state displaying part for displaying a partway state of the content-move by the content-managing part.

17. A content move system for moving a content recorded on a first recording medium to a second recording medium, the content move system comprising:

a content-sending apparatus for reading a content from the first recording medium, and

a content-recording apparatus for recording the content on the second recording medium,
