Abstract: The present invention provides an information processing device for estimating usage of contents and properly limiting functions realized through use of the contents in accordance with the estimation. Usage of contents is estimated by determining in which of cache memory means and content storage means the contents are stored. When the contents are processed or executed, it is determined whether to limit functions realized through processing or execution of the contents, on the basis of the estimated usage of the contents and function limit information showing a rule regarding limits on functions realized through processing or execution. On the basis of the determination, the functions realized through processing or execution of the contents are limited.

Abstract: The present invention provides a means for reflecting modifications made in a server to data with regard to a scope of rights, which are granted to an application program operable in a communication device such as a mobile station, on data stored in the communication device. To achieve the aim, in a system according to the present invention, Java-AP software is provided to a mobile station by transmitting an ADF, a SDF and a JAR file from servers to the mobile station in that order. The SDF is a file containing data indicating restrictions of behavior of a Java-AP in a mobile station. The SDF also contains data indicating a validity state of the SDF, namely ‘valid’ or ‘invalid’, which is managed by management server device 18. Before a mobile station runs a Java-APP which is installed in the mobile station, the mobile station accesses management server device 18 and checks whether a SDF corresponding to the Java-APP is valid.

Abstract: The present invention provides a method for making it more convenient for a user to try out contents. When contents are received, the contents are written in a free space or a space where some data is already stored, of cache memory means. When contents are written in the cache memory means, the contents are processed or executed. When a command is issued using operation means for storing contents processed or executed, the contents are read from the cache memory means, and written in content storage means.

Abstract: A high-frequency choke circuit comprises a dielectric layer covered with grounding conductors, a lead line of high-impedance and at least one capacitance land formed within the dielectric layer, and at least one through-hole connecting the lead line and the capacitance land. The capacitance lands are disposed closer to the grounding conductors, resulting in large capacitances with small areas. The capacitance lands are formed on a layer distant from the layer on which the lead line is formed. Therefore, unnecessary electromagnetic coupling with other circuits formed on the same layer as the lead line can be reduced. The grounding conductors cover both surfaces of the dielectric layers that incorporate the capacitance lands and the lead line to thereby shield the circuit formed in the dielectric layers electromagnetically from outside.
