Patent attributes
Systems and methods for obtaining and maintaining operable and updated versions of software on a client, which may be a set-top box or a personal computer. A server automatically downloads software updates over a satellite link to a client after such upgrades become available at the server without requiring interaction with a user. Similarly, corrupted software is automatically replaced by the client first automatically detecting if a corrupted state exists in local software or data using a checksum technique. If such corruption is found, the client automatically connects over the Internet to a server that contains a replacement for the corrupted program or data. The client then automatically receives a download of the program or data from the server.
