Abstract
A method for updating contents of a Digital Media Server (DMS) in a digital living network alliance system (DLNA) is disclosed. An update process is performed through a periodic update event in a Digital Media Player (DMP) that receives all content information of the DMS. Upon determining that information loss has occurred in the update process, the DMP sends to the DMS a request for information about a list of items possessed by the DMS. The DMP receives the requested information about the list of items and compares the received information about the list of items with information about pre-stored items to obtain a comparison result. When a difference occurs as the comparison result, all information about contents of the DMS is obtained through a browse action. When the difference does not occur as the comparison result, the update process is continuously performed.
