摘要： Transmission of contents from a transmitting apparatus to a plurality of receiving apparatuses is performed, while putting restrictions on a communication area and the number of receiving apparatuses in conformity with a definition of DTCP. In a case of a need to distribute literary works such as movies and the music within a single home network, while preventing the transmission of the literary works to other home networks, a degree of freedom in communication is raised in a case where a communication delay time is short so that a high possibility exists that the communication delay time falls within a specific range. Conversely, in a case where the communication delay time is long so that a low possibility exists that the communication delay time falls within the specific range, the degree of freedom in communication is lowered. Thus, it is allowable to implement a system that ensures a high barrier to unauthorized content distributions, and also, does not have any remarkable restrictions on a rightful home use.

摘要： An information processing apparatus and an information processing method capable of preventing information from being copied illegally. where a hash function and a service key are stored in advance in an EEPROM of a DVD player serving as a source. In an BEPROM 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 lID 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： There is provided a configuration enabling prevention in advance of leakage and outflow of secret information in the local network, such as private data and content whose copyright and use right is restricted. A plurality of identification information of a communication destination device are acquired at different data processing levels. Identification information acquired by data processing at a level of a physical layer or a data link layer of the OSI reference model and identification information acquired by data processing at a layer level of a network layer or higher are received and these identification information are matched. In addition, at least one of identification information receives generated data generated by an encryption process or a hash value generation process based on secret information shared with the communication source device. By matching a plurality of identification information and in accordance with a satisfied or an unsatisfied state of the matching, it is determined whether or not the communication destination device is a device connected to the same local network.

摘要： An information-processing apparatus, functioning as a content-utilization management server, includes a storage unit for storing a list of member clients, which are each a client having a right to utilize a content, and a data-processing unit for carrying out a process to register a client on the list of member clients to serve as a member client. The data-processing unit carries out a process to register a client on the member-client list to serve as a member client on condition that results of confirmation indicate that a client making a request for registration of the client to serve as a member client is a client in the same local network as the content-utilization management server and indicate that a user of the content-utilization management server has given an approval of the requested registration of the client to serve as a member client.

摘要： A plurality of copies of an information signal are prevented from being formed. For example, a transmitter such as IRD, STB, or the like transmits an information signal supplied from the outside via a radio wave or the like to each apparatus in a system. Together with a monitor, a speaker, and the like, for example, two recorders such as VTRs or the like are provided in the system. It is assumed that the recorder is executing the recording operation. The transmitter recognizes that the recorder is under the recording operation. Even if the other recorder issues a request indicating that it wants to perform the recording operation in this situation, the operation responsive to the request is not permitted. By such a management, a plurality of recorders in the network are prevented from recording the same information signal. A plurality of copies are prevented from being formed with respect to the same information signal.

摘要： A transmitting apparatus and method, and a receiving apparatus and method for communicating a pack of 2,048 bytes using the digital interface in accordance with the IEEE 1394 standard. A 4-byte time stamp is added to a 2,048-byte pack of MPEG (Moving Picture Experts Group)—PS (program stream) data. Also, 124 bytes of padding data is added to this pack in order that the overall byte length of data be a multiple of 16. Then the data is divided into a number of fractions which is a multiple of 2 (e.g., 32), thereby being converted into a number of data blocks equal to the number of fractions. Each data block has a byte length of a multiple of 4 (e.g., 68 bytes). A CIP header and the like are added to a predetermined number of the data blocks to form a packet.

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： A method and apparatus for transmitting data among devices connected to a serial data bus at maximum speeds are disclosed. Each device may be capable of transmitting data at several speeds. A transmitting device first transmits a data packet to a target recipient device at a maximum transmission speed of the transmitting device. If an acknowledgement signal confirming receipt of the initial data transmission is received from the target recipient, then the transmission speed for subsequent data packet transmissions's set to the speed of the just-transmitted data. Otherwise, the transmission speed is reduced and the process is repeated. Once an acknowledgement is received and the speed is set, the speed may be stored in a memory of the transmitting device for use in future communications with the recipient device. The process is repeated to establish maximum suitable transmission speeds to other target devices connected to the bus. The invention has particular utility when used in conjunction with an IEEE 1394 serial bus interface in the absence of a bus manager. Following a bus reset operation in which the memory of each device is cleared, individual devices reestablish appropriate data transmission speeds to each of the other devices by transmitting packets at varying speeds, if necessary, until acknowledgements are received.

摘要翻译： 公开了一种用于在以最大速度连接到串行数据总线的设备之间传输数据的方法和装置。 每个设备可能能够以几种速度传输数据。 发送设备首先以发送设备的最大传输速度向目标接收方设备发送数据分组。 如果从目标接收方接收到确认接收到初始数据传输的确认信号，则将后续数据分组传输的传输速度设置为刚发送的数据的速度。 否则，传输速度降低，重复处理。 一旦接收到确认并且设置了速度，则速度可以存储在发送设备的存储器中，以用于将来与接收设备的通信。 重复该过程以建立与连接到总线的其他目标设备的最佳合适的传输速度。 在没有总线管理器的情况下，当与IEEE 1394串行总线接口结合使用时，本发明具有特别的用途。 在每个设备的存储器被清除的总线复位操作之后，如果需要，各个设备通过以不同的速度发送分组来重新建立到每个其他设备的适当的数据传输速度，直到接收到确认。

摘要： Content is transmitted within a range of the user's legitimate use while limiting the number of equipment to which the content is transmitted at the same time.A content using apparatus periodically transmits an exchange key and the corresponding key ID using a command. Only while receiving the key ID at predetermined reception cycles, a content providing apparatus maintains the corresponding exchange key. When not periodically receiving the key ID, the content providing apparatus destroys the corresponding exchange key. After that, when receiving a command including the key ID, the content providing apparatus returns a response including information indicating that the exchange key has become invalid.
