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 between a first device and a second device, the method comprising:
- comparing a first content state for contents stored in the first device and a second content state for contents stored in the second device if the first device and the second device are connected to each other; and
transmitting a whole or a portion of at least one content to each other to synchronize the content state if the first content state for the at least one content does not match the second content state for 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.
