METHOD FOR SYNCHRONIZING MULTIPLE CDS DEVICES, CDS DEVICES AND SYSTEM THEREOF

摘要

A method and a system for synchronizing a plurality of CDS devices, and the CDS device thereof are provided to synchronize contents stored in the respective CDS devices, and minimize synchronization time and network traffic due to the synchronization by lowering dependency on an AP(Access Point) after a synchronization time point of the CDS devices. A synchronization descriptor(220) includes synchronization information with other CDS devices to be synchronized. A synchronization descriptor manager(230) manages the synchronization descriptor. An embedded AP(210) transceives the synchronization information with other CDS devices. The synchronization descriptor includes ID information of an object to be synchronized in the CDS device, object change information, and synchronization policy information. The synchronization descriptor is shared with other CDS devices to be synchronized with other CDS devices. A storing part(240) obtains and stores change information of the synchronization information by using the shared synchronization information. The embedded AP performs the synchronization by using the change information.
