ABSTRACT:
A method of synchronizing a plurality of content-directory service (CDS) devices is provided. The method includes retrieving and discovering N CDS devices in a home network by a control point (CP), transmitting a StartSync message that requests the start of synchronization to a certain CDS device of the N CDS devices by the CP, forwarding a StartPeerSync message that informs remaining N-1 CDS devices of the fact that synchronization will be started by the CDS device that has received the StartSync message, and synchronizing each of the N CDS devices with the remaining N-1 CDS devices, in a home network that includes N CDS devices that provide metadata of multimedia content existing in the home network, and the CP that receives metadata from the N CDS devices and requests the media renderer to replay the multimedia data.
