Abstract: An in-flight entertainment system is shown wherein digital content servers are interconnected with network servers such that the content servers can communicate with one another and with a portable data loader. The loader stores digital content files that are to be downloaded to the content servers. A script downloaded to each content server is executed by the server to download some of the files from the portable data loader and cross-load other files from other content servers. Alternatively, a content inventory list is downloaded to each content server that indicates which content server is to download each content file and which content servers are to receive the content file. Each content server parses the list to identify files for which it is the download server, request download of those files, identify other files that it should have and request cross-load of those files from other content servers.

Abstract: A method and system are provided for updating software configurations of line-replaceable unit (LRU) computers in a restricted architecture network such as an in-flight entertainment system (IFES). Operating in an efficient and parallel manner, each of the LRUs independently creates an individual configuration file that identifies current software components. Each of the LRUs transmits its respective configuration file to a configuration server either automatically upon startup or manually upon request. The configuration server updates a system configuration data file with the current configuration files received from the individual LRUs. In a downloading method, a download server sends a list of desired software components to the LRUs. Each of the LRUs independently and simultaneously transfer (download) the needed software from the download server. The LRU independently requests the download server to download the needed software components.
