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.
