摘要： A method of information processing in a server/client system including a server for storing content and a client for receiving from the server and storing copy content of the content stored in the server. The method includes the steps of: the server generating at least either a content-ID list storing content-IDs corresponding to content for which use-expiration-date updating is permitted out of the copy content stored in the client or a content-ID list storing content-IDs corresponding to content for which use-expiration-date updating is not permitted, transmitting the content-ID list to the client; and the client selectively performing update processing of use-expiration date out of the copy content stored in that client or invalidation processing of the copy content stored in that client based on the content-ID list received from the server.

摘要： Providing a function of isolating a home network from an external network for a router or a gateway, which are interposed between the home network and the external network, so as to isolate or disconnect the home network from the external network when, for example, the home server registers a client as a member or provides the contents or issues a license thereof, thereby ensuring a client making a request is present in the local environment. It is possible to manage the contents legitimately acquired on the home server so as to be used by a client terminal within the scope of private use allowed by the copyright law.

摘要： An information processing apparatus and an information processing method are capable of preventing information from being copied illegally. To put it in detail, a hash function and a service key are stored in advance in an EEPROM of a DVD player serving as a source. In an EEPROM of a personal computer (PC) serving as a sink, on the other hand, its ID and a license key are stored beforehand. The DVD player requests the PC to transmit the ID. The DVD player then applies the hash function to data resulting from concatenation of the ID with the service key to generate a license key (=hash (ID ∥ service-key)). Subsequently, the DVD player generates a source side common session key and encrypts the session key by using the generated license key. Then, the DVD player transmits the encrypted source side common session key to the PC. The PC decrypts the encrypted source side common session key by using the license key stored in its EEPROM to produce a sink side common session key which has a value equal to that of the source side common session key.

摘要： The encoded data outputted from a DVD player 1 are outputted to and decoded in the decoders 4-1 to 4-3 of digital television receivers 3-1 to 3-3 through an AV bus 5 comprising the IEEE 1394. When a command for changing a system parameter is inputted to any one of the decoders 4-1 to 4-3, the command corresponding to the change is supplied to the DVD player 1 through the AV bus 5. The DVD player 1 changes the system parameter in response to the command and outputs the system parameter to the respective decoders 4-1 to 4-3 through the AV bus 5. Thereby, the system parameter is changed not only in the DVD player but also in other components.

摘要： The construction of a receiving apparatus for receiving a broadcast from a plurality of broadcasting providers is simplified. In a receiving apparatus for receiving a broadcast from a plurality of broadcasting providers, of the function blocks which constitute the receiving apparatus, a block used in common irrespective of the broadcasting provider is formed as a common block, and a block different from one broadcasting provider to another is formed as an independent block. These blocks are connected to each other through an IEEE1394 interface, and the common block is shared among the plurality of blocks which are not used in common, so that a receiving process is performed.

摘要： In a digital broadcast receiving apparatus, digital broadcast signals provided by a digital broadcast method are supplied to various types of external units and are effectively utilized. In the above apparatus, a descrambler descrambles a transport stream output from a front end unit and supplies it to a digital interface and a demultiplexer. The demultiplexer extracts from the transport stream a compressed video signal and a compressed audio signal of a program specified by a user, and supplies the extracted signals to an MPEG decoder. The MPEG decoder decompresses the supplied video signal and the audio signal and supplies them to the digital interface, an NTSC encoder, and an audio signal D/A converter. The digital interface supplies either of the transport stream or the decompressed data to a digital external unit under the control of the controller.
