Abstract

A network client aggregates media items available in a media system. The network consists of a plurality of nodes, including at least two media server nodes. A client node generates an internal request to obtain a list of media items available in the media system. In response, the client node generates a request for a list of media items from each individual media server node on the network. Each media server node sends their list of media items to the client node. The client node aggregates the lists of media items from each of the media server nodes. Thus, a list of media items available on the media system is aggregated to a requesting client node in the media system.
