Abstract: A Download Control Message instructs a set-top terminal in a cable television system to located and immediately begin downloading a code or other data object available over the cable system. The Download Control Message specifies, for example, the size, name, version and location (URL or transport stream and PID) of the object to be acquired by the set-top terminal. The terminal accordingly can begin immediate acquisition of the object. An address or other characteristic associated with the Download Control Message allows the system operator to target the Message to a particular set-top terminal or group of terminals.

Abstract: A method and system manages and controls the download of programming, i.e., code objects, to a set-top terminal connected to a cable television system so as to prevent disruptions to service that may arise if only some of the objects specified are successfully downloaded and might, therefore, function improperly or conflict with existing applications. When the message to download new or additional code objects lists two or more objects to be acquired, the set-top terminal will only enable and execute downloaded objects if all the listed objects are successfully acquired. If only some of the objects the terminal has been instructed to download are acquired, those downloaded objects may either be purged or stored in memory without being enabled and executed. The system operator may specify in the message instructing the terminal to acquire new objects, whether the listed objects must be implemented as a group or not at all.
