摘要： A device registration system for registering a terminal device for obtaining and using contents in a server that stores contents. The server stores a contents list indicating contents stored and a registration list for registering specific information to the terminal device. The server receives the specific information and transmits the contents list to the terminal device. The terminal device receives a selection of a content from the contents list according to input by a user and requests the server to transmit the selected content. When the specific information to the terminal device of the request source is not registered in the registration list, the server performs a registration process and transmits the requested content to the terminal device.

摘要： A system including a server holding content and a terminal using the content, whereby the terminal is registered in the server if a communication time between the terminal and the server is less than or equal to a reference value. A measuring unit of the server measures a communication time from transmitting measuring information to the terminal until receiving response information from the terminal, and repeats the transmission, the reception, and the measurement until the measured communication time is less than or equal to the reference value. An elapsed-time measuring unit measures an elapsed time from when the measuring unit first begins measuring the communication time, and a transmission unit transmits, to the terminal, status notification information showing a processing status depending on the elapsed time. A response unit of the terminal receives measuring information from the server and transmits response information to the server when the measuring information is received.

摘要： A device registration system including a server which holds content and a terminal apparatus which uses content, whereby the terminal apparatus is registered in the server if a communication time between the terminal apparatus and the server is less than or equal to a reference value. A measuring unit of the server measures the communication time, being a time period from transmitting measuring information to the terminal apparatus until receiving response information from the terminal apparatus, and repeats the transmission, the reception, and the measurement until the measured communication time is less than or equal to the reference value. An elapsed-time measuring unit measures an elapsed time from when the measuring unit first begins measuring the communication time, and a transmission unit transmits, to the terminal apparatus, status notification information showing a processing status which depends on the elapsed time. A response unit of the terminal apparatus receives measuring information from the server and transmits response information to the server when the measuring information is received, and a display unit displays a message based on status notification information received from the server.

摘要： The conventional method of limiting the number of receiving apparatus has a problem that if the limited number of appliances is reduced to limit distribution to unspecified appliances outside a home, distribution to appliances in the home is limited unnecessarily. If the limited number of appliances is increased, distribution to appliances outside the home cannot be sufficiently limited. The invention provides at least one receiving apparatus, (e.g., digital television sets and PCs,) connected to a network and capable of receiving and using predetermined data, and a transmitting apparatus, (e.g., an AV server) for transmitting the data to the receiving apparatus via the network. Use of the data on the network is managed based on the transmission time required for transmission of predetermined information between the transmitting apparatus and the receiving apparatus.

摘要： In the conventional file management system, there is a problem that even a file assigned permission information can be processed without considering any permission information. Therefore, the system includes a first accumulation device 2 for accumulating files to which permission information is added, and a new file management apparatus 7 for performing an input/output process on files with a request for a process from the application A 10 accessing the file management system taken into account according to the permission information added to the file. The new file management apparatus 7 compares the permission information added to the file in the first accumulation device 2 with the request contents of the process for the file from the application A 10, determines whether or not the process can be performed on the file, inputs the file from the first accumulation device 2 based on the result, and outputs it to the application A 10.

摘要： The data transmission system can substantially prohibit illegal copy of real data since the encryption key applied to transmitted data is changed depending on copy management information, thereby the real data being decrypted and recorded with a key different from the original key when the copy management information is tampered. Thus, the transmitted data can be further securely protected than in the prior art.

摘要： In a server, an echo-request transmitting unit transmits echo-request data to a target device, and an echo-reply receiving unit receives echo-reply data from the target device. A time measuring unit measures, as the target time, the time required between transmission of the echo-request data and reception of the echo-reply data, and compares the target time with the reference time. In this way, the server judges whether the target device connected to its network belongs to a predetermined group.

摘要： A key delivery apparatus that prevents improper use of contents, and manages a decryption key for decrypting encrypted content and a suppliable number showing how many times the decryption key is suppliable, with respect to one or more terminal apparatuses connected to a network. The key delivery apparatus receives a supply request for the decryption key from a terminal apparatus, and if the terminal apparatus is a legitimate supply target, judges whether the terminal apparatus is a first-type that manages a content-usage period or a second-type that does not manage the content-usage period, and if the suppliable number has a remaining number, supplies to the terminal apparatus, the decryption key and a key-usage period of the decryption key when judged that the terminal apparatus is the first-type and the decryption key when judged that the terminal apparatus is the second-type.

摘要： A content management system which can prevent a content from being copied exceeding the limited number of copies for the content. The content management system includes a first content management device and a second content management device. The first content management device stores period information that indicates an available period during which a first external device is permitted to use a copied content which has been copied from the content, and outputs the period information to the second content management device when the content is moved. Upon receiving the period information from the first content management device, the second content management device judges whether the available period of the copied content has expired, using the received period information, and if it is judges that the available period has not expired, it inhibits the content from being copied to the second external device.

摘要： A time authentication device identifies clocks that show a time falling within the predetermined permissible range as compared with a time shown by the time authentication device. In a time authentication device embodied as a distribution device, a time-relation information storage unit stores a playback-device-time measured by a clock unit of a playback device, and also stores a distribution-device-time measured by a clock unit when the playback-device-time is acquired. The time authentication unit acquires from the playback device a target time measured by the clock unit, and also acquires an authentication time measured by the clock unit when the target time is received. The time authentication unit then calculates a first difference, a second difference, an authentication difference. If the authentication difference is smaller than or equal to a predetermined threshold, the time authentication unit judges that the clock unit of the playback device is valid.
