A computer program for removing duplicate objects from an object store. The program allows the user to select which properties of the objects will be compared to determine equivalence. These properties are then read and a signature number is calculated based on the values of the those properties, using the cyclic redundancy code. Prior to the calculation of the signature, special cases are accounted for by modifying the properties. Such special cases can include: missing critical properties which can be calculated, text field formatting and leading and lagging spaces, order of attachments, order of categories, name properties, and recurring appointments. Once the signature values are calculated, objects with the same signature are, by definition, equivalent by the properties the user selected. Prior to discarding all but one of the equivalent objects, the program can check whether the object contains a link. As between two equivalent objects, the one with the link should be retained.

A method for updating contents of a Digital Media Server (DMS) in a digital living network alliance system (DLNA) is dislcosed. 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.
