The exemplary embodiments of this invention provides a method and apparatus that features synchronizing of data objects in a client device with a server in a system since a last synchronization between the client device and the server by obtaining a list of added or modified data objects since the last synchronization, updating a cached object list on the client device with the list of added or modified data objects, obtaining a sorted list of existing data objects from the server, and detecting deleted data objects based on the comparison between the updated cached object list and the sorted object list. In particular, the synchronizing may include a control point periodically synchronizing the data objects with a content directory service (CDS) in a Universal Plug and Play (UPnP) device architecture (UDA).
