First Claim
1. A method for determining an object update by a media controller in a home network, the method comprising:
- receiving and storing a system update identifier (systemUpdateID), when accessing a media server;
receiving an object update identifier (objectUpdateID) and an initial update identifier (initUpdateID) for an object, when re-accessing the media server;
comparing the received objectUpdateID and initUpdateID with the systemUpdateID; and

Abstract
A method and apparatus for determining an object update in a home network. In a method for determining an object change in a home network, a media controller receives an object update identifier (objectUpdateID) and an initial update identifier (initUpdateID) for an object from an accessed media server, compares the objectUpdateID and the initUpdateID with a system update identifier (systemUpdateID) that was previously stored in the media controller, when the media controller previously accessed the media server, and determines whether the object is updated according to the comparison result.
