  • Synchronizing content between content directory service and control point
    Patent number: 8037022
    Abstract: In one embodiment, a method is performed at a control point (CP) in a network. An action is invoked to create a synchronization data structure on a media server that includes a content directory service (CDS) in the network, wherein the synchronization data structure includes a synchronization relationship describing a relationship between the CP and the CDS. Then an action is invoked to add synchronization pair information to one or more objects on the CDS. A change log is requested from the CDS. Then the change log is received from the CDS, wherein the change log contains information about changes to the one or more objects to which synchronization pair information for the CP was added.
    Type: Grant

  • Method and system for content synchronization and detecting synchronization recursion in networks
    Patent number: 7739411
    Abstract: A method and system implementing a process for content synchronization that detects and prevents synchronization recursion in CDS transfer operations. A synchronization relationship is formed between the CDS containers in multiple devices. Then content synchronization processes are performed based on that relationship to avoid synchronization recursion.
