Abstract:
1. A method for updating contents of a Digital Media Player (DMP) in communication with a Digital Media Server (DMS) in a network having IP connectivity and including a Hypertext Transfer Protocol (HTTP) server and client, comprising the steps of: a) performing an update process through a periodic update event in the DMP that receives all content information of the DMS in eXtensible Markup Language (XML) format through a modified browse action in which a state variable is defined relative to the DMS and the state variable obtains a smaller amount of data than by a non-modified browse action; b) sending a request for information by the DMP about a list of items possessed by the DMS to the DMS, upon determining that information loss has occurred in the update process; c) receiving from the DMS by the DMP information about the list of items and comparing by the DMP the received information about the list of items with information about pre-stored items at the DMP to obtain a comparison result, the list of items including information about item tree layers and layer-by-layer IDs in the form of the state variable with a maintained state variable at the DMP for the given DMS to obtain the comparison result; d) obtaining by the DMP all information about contents of the DMS associated with received information indicated to be different in XML format through the browse action when a difference occurs as a comparison result of step c).
