METHOD AND APPARATUS FOR SYNCHRONIZING METADATA AND MEDIA BASED ON UPNP PROTOCOL

摘要

A method and apparatus to synchronize multiple UPnP content directory services (112, 122) without using CDS tracking or content synchronization service is disclosed. The method may include discovering mediaservers (110, 120) coupled to a network, comparing respective metadata fields from the discovered mediaservers, updating the metadata fields based on the comparison. A control point (130) gets metadata of media objects that need to be synchronized. The control point invokes a comparemetadata action to ascertain the differences in the objects, upon acquiring the difference between the metadata parameters of a sync object in a first CDS with sync pairing object in a second CDS the control point invokes appropriate UPnP actions to ensure the two objects are synced.
