TRIGGER FOR TARGETED BRUTE FORCE SYNCHRONIZATION IN A UPNP CLIENT-DRIVEN SYNCHRONIZATION MODEL

摘要

A system for improved synchronization with regard to changes in a CDS media library. A property is added to the LastChange state variable that indicates a particular container to which changes have been made. Information can also be appended to the state variable indicating whether there have been additions, deletions, or other types of changes to the appropriate sub-tree container. This new property triggers a control point to browse and search in order to obtain a complete list of changes. In a particular embodiment, this trigger is only added to objects for which it is impractical to deliver the entire list of changes via notifications.
