Abstract :
Universal Plug and Play Audio Video (UPnP-AV) is a widely accepted standard to enable multimedia device interoperability in home networks. In UPnP-AV, contents are managed and exposed to Control Point and MediaRenderer in MediaServer. Content Directory Service (CDS) in MediaServer is the key component to enable multimedia retrieval and delivery functions by modeling contents in DIDL-Lite and utilizing various metadata. However, the metadata integrating with CDS is not easy when considering interoperability together. More, the metadata model in UPnP AV is a static limited set and lack of semantic capability. To maximize the quality of user experience and performance of implementation, this paper proposes an approach to do the metadata integration based on a comprehensive survey and presents a novel metadata infrastructure for UPnP AV approach to overcome the disadvantages.
