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 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.

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.

13. 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:
-
transmitting content reproduced in the content storage device to the portable content player; determining whether the content is completely reproduced in the content storage device if the content storage device stops reproducing the content; and deleting the content from the portable content player and updating the content state list of the portable content player if the content is completely reproduced. - View Dependent Claims (14, 15, 16, 17, 18, 19)

20. A method of reproducing content in a first device that was partially reproduced in a second device, the method comprising:
-
transmitting the partially reproduced content from the second device to the first device; determining a reproduction-interruption point in the partially reproduced content; and reproducing the content from the reproduction-interruption point. - View Dependent Claims (21, 22, 23, 24)
