Portable content player, content storage device, and method of synchronizing content state lists between portable content player and content storage device
First Claim
1. A method of synchronizing content state lists between a portable content player and a content storage device having a content reproduction function, the method comprising:
- generating a first content state list for contents stored in the content storage device and a second content state list for contents stored in the portable content player;
generating an execution list by comparing the first content state list and the second content state list if the portable content player and the content storage device are connected to each other, wherein the execution list including synchronization command for at least one content if the content state in the first content list for the at least one content does not match the content state in the second content list for the at least one content; and
synchronizing the at least one content between the portable content player and the content storage device to match the first content state list with the second content state list by executing the synchronization command included in the execution list on the at least one content, wherein the synchronization command included in the execution list is one of an update command of the at least one content on the first content state list or the second content state list, a transmission command of a whole or a portion of the at least one content, and a delete command of the at least one content.

Abstract
A portable content player, a content storage device, and a method of synchronizing content between the portable content player and the content storage device, the method including: generating a first content state list for content stored in the content storage device and a second content state list for content stored in the portable content player; generating an execution list based on the first content state list and the second content state list; and matching the first content state list with the second content state list by executing a synchronization command included in the execution list on content selected to be synchronized. Accordingly, a user can automatically match the content state lists of the portable content player and the content storage device.

9. A method of synchronizing content state lists between a first storage device and a second storage device, the method comprising:
-
generating a first content state list for contents stored in the second storage device and a second content state list for contents stored in the first storage device; generating an execution list by comparing the first content state list and the second content state list if the first storage device and the second storage device are connected to each other, wherein the execution list including synchronization command for at least one content if the content state in the first content list for the at least one content does not match the content state in the second content list for the at least one content; and synchronizing the at least one content between the first storage device and the second storage device to match the first content state list with the second content state list by executing the synchronization command included in the execution list on the at least one content, wherein the synchronization command included in the execution list is one of an update command of the at least one content on the first content state list or the second content state list, a transmission command of a whole or a portion of the at least one content, and a delete command of the at least one content. - View Dependent Claims (10, 11, 12)

13. A content storage device having a content reproduction function and performing content synchronization with a portable content player, the content storage device comprising:
-
a content storage unit to store contents; a content state list generator to generate and to update a first content state list for the contents stored in the content storage unit; an execution list generator to generate an execution list by comparing the first content state list and a second content state list for contents stored in the portable content player if the portable content player and the content storage device are connected to each other, wherein the execution list including synchronization command for at least one content if the content state in the first content list for the at least one content does not match the content state in the second content list for the at least one content; and a synchronization controller to synchronize the at least one content between the portable content player and the content storage device to match the first content state list with the second content state list by executing the synchronization command included in the execution list on the at least one content, wherein the synchronization command included in the execution list is one of an update command of the at least one content on the first content state list or the second content state list, a transmission command of a whole or a portion of the at least one content, and a delete command of the at least one content. - View Dependent Claims (14, 15, 16, 17, 18)
