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： 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： 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 highly-convenient content duplication management system for allowing users to duplicate a content as long as the duplication is in compliance with a given usage right. In the system, a request destination device stores a content and a permitted number of duplications of the content. In response to a duplication request, the request destination device judges whether or not the request source device is an in-group device that belongs to the same group as the request destination device. When judging that the request source device is an in-group device, the request destination device transmits the content together with a permitted number that is equal to or smaller than the currently stored permitted number. The request destination device then updates the currently stored permitted number by subtracting the permitted number transmitted.

摘要： A content management system formed from a playback apparatus that requests and plays content, and a content management apparatus that manages duplication and deletion of content. The playback apparatus notifies group information of the playback apparatus to the content management apparatus, acquires information from the content management apparatus showing whether requests are permitted, and duplicates/deletes content. By judging whether the playback apparatus belongs to a group, and notifying whether a duplication request is permitted or rejected, based on in-group and out-group remaining numbers that show the remaining number of duplications permitted of apparatuses in-group and out-group, respectively, the content management apparatus relaxes restrictions on in-group content duplication as compared with out-group content duplication, and thus improves convenience for users in a home network, while protecting the rights of copyright holders, with respect to content duplication and usage.
