Portable content player, content storage device, and method of synchronizing content state lists between portable content player and content storage device

摘要

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.

1. A method of synchronizing content state between a first device and a second device, the method comprising:
determining whether the first device and the second device are connected to each other; selecting content according to a synchronization command included in an execution list; synchronizing a first content state list of the first device and a second content state list of the second device with respect to the selected content; determining whether a first content state of the first content state list for the selected content stored in the first device matches a second content state of the second content state list for the selected content stored in the second device when the first device and the second device are determined as being connected to each other; and receiving, using the first device, at least a portion of the selected content being reproduced in the second device from the second device based on a result of the matching by executing the synchronization command; and updating the first content state to synchronize the first content state and the second content state based on the result of the matching.
