Abstract: This invention provides an option management system, an option management method and a recording medium for a digital device which can charge expenses when an optional function is added, and is superior in the convenience and security. The option management system comprises a user terminal, a client terminal, and a digital device connected via a network to the user terminal and the client terminal, which performs a control process for validation or invalidation if a license key purchased by the user for an optional function of each software for monitoring, controlling and maintaining the device itself is inputted from the user terminal.

Abstract: A control device ensures system booting without delay or failure even if the system cannot be booted using newly downloaded upgraded software. Nonvolatile storage 14 stores booting software used for system booting at the time of system power on or reset, and booting software information which designates the booting software. At the time of booting software upgrade, download unit 12 downloads the upgraded version of the booting software and stores it in nonvolatile storage 14. Booting unit 13 boots the system using the upgraded software if the data thereof is normal, otherwise boots the system using the booting software.

Abstract: A pseudo-file system and a WEB server faculty are installed in a transmitting apparatus retaining no file system. A control terminal that monitors this transmitting apparatus has a configuration in which a general-purpose WEB browser is used for monitor and control.

Abstract: A transmission device 100 stores a plurality of sets of setting data in a backup area 103 thereof, and uses any setting data in response to a command from an external terminal 200 to start up the own device. Accordingly, the user can automatically register a desired device configuration solely by selecting a device mode.

Abstract: The present invention causes a pseudo-file system and a WEB server faculty to be installed in a transmitting apparatus retaining no file system. And, a control terminal that monitors this transmitting apparatus assumes a configuration in which a general-purpose WEB browser is used for monitor and control.

Abstract: In a backup data management device of the invention, when the number of update times of either the first or the second divisional region exceeds a given number of times, blocks A and B assigned to first and second divisional regions, respectively, are exchanged. As a result of the block exchange, block B is newly assigned to the first divisional region, and block A is newly assigned to the second divisional region. As a result, after the block exchange, when operation data A is updated again, backup data corresponding to the operation data A in the second divisional region is updated.
