Method and apparatus for synchronizing device providing content directory service with device not providing content directory service

摘要

Provided is a method for synchronizing contents included in devices in a Universal Plug and Play (UPnP) network. A control point device, which contains local content but cannot provide a content directory service, converts information regarding content objects of the control point device into Digital Item Description Language Lite (DIDL-Lite) format, and manages a mapping table, thereby performing synchronization with a device such as a UPnP media server providing a content directory service, without loading a separate protocol stack.
