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.
