Abstract: An electronic asset utilization system is constituted of a stationary terminal 11, such as a set-top box (STB), a mobile terminal 13, such as a portable cellular phone, and a server 15. The server 15 receives an order for an electronic asset from the stationary terminal 11 or the mobile terminal 13; downloads to the stationary terminal 11 or the mobile terminal 13 an electronic asset and an exchange or receipt certificate to be described later; retains the thus-issued electronic asset, exchange certificate, or receipt certificate; and settles a charge billed to the thus-ordered electronic asset. The stationary terminal 11, the mobile terminal 13, and the server 15 are connected to a communications network.

Abstract: A content delivery method for exporting content from a server to a terminal includes acquiring information on right management capability supported by the terminal, the information being reported from by terminal. The content that is appropriate to the terminal is selected based on the acquired information, and the selected content is delivered to the terminal in response to a request from the terminal.

Abstract: An information export method for exporting content and right information of the content to a repository includes referring to the right information when the content is exported to the repository and checking whether the repository is allowed to have the content based on a description of the right information. When the repository is not allowed to have the content, it is determined not to export the content and the right information to the repository.

Abstract: An information processing apparatus is disclosed capable of using application programs of both a cellular phone and a non-contact card type terminal in cooperation, and performing a process request with respect to a portable terminal in response to a command received by the non-contact card type terminal from a communication terminal. When a communication terminal 30 requests a second device (SE: non-contact card type terminal) 20 of an information processing apparatus (hybrid portable communication terminal) 70 to process data in response to a predetermined command in a predetermined non-contact communication system, a command transmission request is transmitted beforehand with respect to a first device (PTD: cellular phone) 10 of the information processing apparatus in another non-contact communication system.

Abstract: Herein disclosed is a communication apparatus to be operative in combination with first and second external devices for respectively producing first and second information, comprising: first information receiving means for receiving the first information from the first external device; communication performing means for performing a communication with the second external device by receiving the second information from the second external device and producing an exchange information to be transmitted to the second external device and; controlling means for controlling the communication performing means by assuming two different operational states including a first operational state to allow the communication performing means to be operable to perform the communication with the second external device and a second operational state to allow the communication performing means to be inoperable to perform the communication with the second external device, the controlling means being adapted to selectively assume th

Abstract: One objective of the invention is to provide a hybrid portable communication terminal, as a data processing apparatus, that can employ together application programs for both a portable telephone and a contactless card terminal and that can communicate with an external device in accordance with a predetermined protocol by using, as needed, an appropriate application program, while another other objective is to permit a local server to identify each terminal.

Abstract: A service item registration area is provided in SE, and only a service server having a specific certificate can provide service using the service item registration area of SE. When processing using data of the service item registration area is performed, exchange of a message with a signature is always performed.

Abstract: To make an electronic value usable for both service on a network and service in the real world while ensuring security, convenience and economical efficiency, the electronic value issued for a user is controlled on an electronic wallet of a private electronic value bank, the electronic value controlled on the electronic wallet of a bank is cached in a mobile electronic wallet on a smart card of a user's portable terminal 5, and the electronic wallet is linked such that it is operated via the network when the mobile electronic wallet is operated. When the electronic value on the smart card is used for the service provided in a real environment such as a ticket gate of a train station, on-line transaction does not occur every time it is used, but the electronic wallet of the bank is updated when the portable terminal and the bank communicate later.

Abstract: An elastic surface wave device comprises a main elastic surface wave filter formed on a piezoelectric substrate made of monocrystalline lithium tetraborate and an auxiliary elastic surface wave filter formed on said piezoelectric substrate and connected in parallel with the main elastic surface wave filter to cancel the higher frequency side unnecessary component attributable to the bulk wave contained in the output of the main elastic surface wave filter.

Abstract: A technique that can enhance convenience on each of both sides that distribute and use content under the conditions where use limitations intended to protect the copyright of content have diversified. According to this technique, a right gateway 100 is provided, that converts the condition of use in the right information of content subject to transmission from repository 20 at the transmitting end to repository 30 at the transmission destination in accordance with the right management capacity (capacity information 200) of content in repository 30 at the transmission destination. With right gateway 100 performing processing, the range of equipment and recording mediums capable of use of content expands, thereby promoting the use of content.

Abstract: The present invention aims to perform safe editing without causing contradiction in relationship in editing a hypertext document and to edit the hyperlink information safely in a document in coordination with editing of the hypertext document associated with said link.

Abstract: Contents of each of nodes indicating a plurality of hyper-text documents are prepared and revised in a node managing unit as node information. A connection-relationship between two nodes is established and revised for each of the nodes in a hierarchy structure managing unit as hierarchy structure information, and a hierarchy structure of the nodes is established. In this hierarchy structure, one node ranked to the top level is set as a parent node, and the other nodes are set to child nodes. Thereafter, a plurality of hyper-text documents arranged in the hierarchy structure are prepared from the node information and the hierarchy structure information. Therefore, because the contents of each node is managed in dependence of the preparation of the hierarchy structure, the hyper-text documents arranged in the hierarchy structure can be easily prepared.
