摘要:
A content reproduction system includes an information processing terminal and a secure device. The information processing terminal receives a copyright protection application program from an application distribution server. The copyright protection application program includes a first program having a first execution format executable in the information processing terminal and a second program having a second execution format different from the first execution format and executable in the secure device. The second program is encrypted with a program key held in the secure device. By extracting and executing the first program, the information processing terminal extracts the second program and transmits the second program to the secure device. The secure device receives the second program from the information processing terminal, decrypts the second program using a program key stored in a key storing unit, and executes the second program.

A layout unit refers to a plurality of menu items stored in a menu item information storage unit by a menu item information obtaining unit. The following processes are performed as necessary to display a large number of menu items in a predetermined part of a GUI screen. A character size reducing unit reduces the size of characters used to display menu items. A margin reducing unit determines the layout of menu items so as to reduce the margins in menu items. An abbreviating unit replaces certain character strings in menu items with shorter character strings. In this way, the layout unit determines the layout of menu items. A menu control unit then has the menu items displayed in accordance with the layout determined by the layout unit.

Disclosed is an apparatus and method for synthesizing a plurality of program component specifications into a single program component specification. Each program component transforms its state in operation, responding to an input of an event and in turn outputs another event in accordance with the transformation to the other program components.The program component specifications each includes a table showing events to be inputted therein, a table showing states of the program component in operation, a table showing state transformations in response to the input events, and a table showing events to be outputted therefrom according to the state transformations.

Proposed is a dielectric thin film of a substituted lead titanate having a chemical composition expressed by the formulaPb(Ti.sub.1-x M.sub.x)O.sub.3in which the subscript x is a positive number in the range from 0.05 to 0.50 and M is an element selected from the group consisting of niobium, tantalum, vanadium, antimony, bismuth, arsenic, tungsten, hafnium, germanium, tin, aluminum and gallium substituting for a part of the titanium atoms in the perovskite crystal lattice of lead titanate. Different from thin films of unsubstituted lead titanate or conventional substituted lead titanates, the above defined dielectric thin films of the invention are free from the disadvantage that the dielectric constant of the thin film is greatly decreased when the thickness of the thin film is so small as to be 1 .mu.m or smaller so that the dielectric constant of the inventive dielectric thin film having a thickness of 0.5 .mu.m or even smaller can be as large as 10 times of that of the thin film of unsubstituted lead titanate having the same thickness.

A focus control device that positions a focus on one of a plurality of graphical user interface (GUI) components displayed on a screen includes request receiving means for receiving a request to move the focus, focus permission information storing means for storing focus permission information indicating, for each GUI component, whether the focus can be positioned on the GUI component, and focus moving means for moving the focus in response to the received request to a GUI component where, according to the focus permission information, the focus can be positioned, the focus moving means skipping over GUI components where the focus cannot be positioned.
