Abstract: A mobile device includes a memory for storing therein a subroutine management table to manage kinds of existing codes out of native code, first code and second code for a plurality of subroutines contained in content, a virtual machine, a precompile circuit for producing second code from first code and a subroutine management circuit for changing over processing in accordance with the kind of existing code for subroutine called up during execution of content. The subroutine management circuit judges kind of existing code with reference to the subroutine management table when the processing is changed over.

Abstract: A storage device includes a tamper-resistant module and a flash memory. In correspondence with a command, a CPU inside the tamper-resistant module judges the security of data received from the outside, then recording the data as follows: High-security and small-capacity data is recorded into a memory inside the tamper-resistant module. High-security and large-capacity data is encrypted, then being recorded into the flash memory. Low-security data is recorded as it is into the flash memory. This recording method permits large-capacity data to be stored while ensuring a security (i.e., a security level) corresponding thereto.

Abstract: An electronic notice-board system for allowing information to be contributed to an electronic notice board. A first short-distance communication device carries out communication with the mobile terminal located in a predetermined communication range and a second communication device exchanges data with the mobile terminal after the user of the mobile terminal has been authenticated. Similarly, the mobile terminal also has a short-distance communication device for carrying out communication with the electronic notice board located in a predetermined communication range and a second communication device for exchanging data with the electronic notice board after the user of the mobile terminal has been authenticated. Since users of the electronic notice board must be close by, it is possible to avoid improper use of the electronic notice board by any user located a long distance away from the electronic notice board.

Abstract: A memory apparatus having a volatile memory for storing data from a host, a nonvolatile memory capable of storing the data stored in the volatile memory, and electrically deleting the data, and a control circuit for controlling data transfer between the volatile memory and the nonvolatile memory. A capacity of a data storage area of the volatile memory is larger than that of a data storage area of the nonvolatile memory.

Abstract: A display system provided with transportability and being accessible from a mobile information terminal, a wireless communication network connects between a server 101 and a display device 102 and between the display device 102 and other display devices in tandem. Each display device has an interface for connecting with a mobile information terminal. The communication interface between each display device and the server or another display device uses one protocol for larger-capacity communication at a higher frequency band than that for the wireless communication interface between each display device and a mobile information terminal.

Abstract: A poster with an RF IC tag is adhered to a poster adhering unit. ID information of the poster is read from the RF IC tag with an RF IC tag reader and sent to a control device. By using this tag ID information, the control device acquires detailed information on each of advertisement contents of the poster adhered to the poster adhering unit, from a contents server. As a user points out a position of the advertisement contents to which the user paid attention, the control device detects the pointed position from an output of ultrasonic sensors, and provides the user with the detailed information by using a display and a speaker in a contents reproducing unit.

Abstract: A terminal notifies a server of a processing method of contents, the server notifies the terminal of an E-mail address associated with the processing method notified to the server, the terminal transmits the contents to the E-mail address in the server that the terminal is notified, the server receives the contents transmitted to the E-mail address, and processes the contents based on the processing method thus notified.

Abstract: A licence hub including a hub apparatus to which one or more apparatus and devices can be electrically connected, and a safe storage device for storing therein keys used to decode the encrypted contents data is added to the existing system to construct a licence network. A controller of the licence network acquires the information of various kinds of apparatuses and devices which are electrically connected to the licence hub, and determines automatically the apparatus and/or the device suitable for executing the processing when carrying out the playback of contents or movement of the key to execute these processings.

Abstract: A display system includes, a server for transmitting data to a map information display device to cause the character to be displayed on a detail information display screen, the map information display device for starting move display animation of the character and transmitting data indicative of move completion to the server, the server for transmitting data to a detail information display device to display the detail information about the shop to which the character is snapped and also transmitting data to display the character on the detail information display screen, the detail information display device for displaying the received detail information about the shop, causing the character to log in on the detail information display screen and to be displayed thereon, and continuously reproducing the move display animation of the character until the character reaches a character display area.
