Abstract
A method, apparatus and system for synchronizing contents are provided. The method for synchronizing contents includes comparing contents stored in a first device with a content list stored in a second device, and deleting contents from the content list or adding contents to the content list. Therefore, is possible to prevent incorrect contents from being browsed even when contents are not completely synchronized.
Claims29
A method for synchronizing contents, comprising:
- comparing contents stored in a first device with a content list stored in a second device, and determining at least one first content which is in the content list but not stored in the first device;
- deleting the first content from the content list;
- and
- adding to the content list at least one second content which is stored in the first device but not in the content list, if the deleting is completed.
A method for synchronizing contents, comprising:
- deleting contents in a first group from a content list stored in a second device based on contents stored in a first device;
- and
- adding contents in a second group to the content list stored in the second device if the deleting is completed.
A content playback apparatus which performs content synchronization with an external device, the content playback apparatus comprising:
- a storage unit which stores a content list;
- and
- a synchronization controller which compares the content list with contents stored in the external device, determines at least one first content which is in the content list but not stored in the external device, deletes the at least one first content from the content list, and adds to the content list at least one second content which is stored in the external device but not in the content list if the deleting of the at least one first content from the content list is completed.
A system for synchronizing contents stored in a first device with contents stored in a second device, the system comprising:
- the first device which transmits a content, which is not in a content list stored in the second device, among the stored contents to the second device, if the first device is connected to the second device;
- and
- the second device which compares the stored content list with the contents stored in the first device, determines at least one first content which is in the content list but not stored in the first device, deletes the at least one first content from the content list, and adds to the content list at least one second content which is stored in the first device but not in the content list if the deleting of the at least one first content from the content list is completed.
A method for having same contents in a first device and a second device, the method comprising:
- establishing a communication between a first device including a content list, to a second device including second device contents;
- and
- automatically synchronizing the second device contents with the content list of the first device when the communication is established, the synchronizing comprising:
- deleting an identifier of a one first content from the content list based on the second device contents and the content list;
- and
- adding one of the second device contents to the first device based on the second device contents and the content list,
- wherein the deleting is performed before the adding.
A method of synchronizing contents between a first device and a second device, the method comprising:
- deleting identifiers of first contents from a content list of the first device, the first contents not being stored in the second device;
- determining second contents stored in the second device, that are not in the content list of the first device;
- and
- adding the second contents to the first device,
- wherein the deleting and the determining are alternatingly performed and after the alternatingly performing of the deleting and the determining is completed, the adding is performed.
