摘要： In order to limit use of content, when a source receives a request for transmitting content from a sink, the source performs an authentication process. When the authentication is successful, the source transmits to the sink key information necessary for decrypting the encryption applied to the content. The sink can receive the content by receiving the key information and by decrypting the encryption applied to the content by using the key information.

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 source apparatus and a conditional access apparatus are disclosed. The source apparatus may transmit a command to the conditional access apparatus. The conditional access apparatus may transmit a response to the command to the source apparatus. When a time elapsed between transmission of the command by the source apparatus and reception of the response by the source apparatus does not exceed a predetermined round trip time (RTT), a first authorization signal to permit the conditional access apparatus to decrypt encrypted content may be generated. Additionally, whenever a non-RTT condition is met, a second authorization signal to permit the conditional access apparatus to decrypt the content may be generated.

摘要： The present invention relates to a telecommunications apparatus and a method, a storage medium, and a program for determining whether or not the other side communicating content data is located on a LAN or across a WAN. In step S13, the difference between a counter value in a received check packet and a value in a register is computed. In step S14, the resultant difference is checked to determine if it is equal to a constant value X. If it is determined that the difference is equal to the constant value X, the counter value in the packet is stored in the register in step S15. In step S16, it is determined whether or not all the predetermined number of check packets is received. If all the predetermined number of check packets is received, it is determined that the communication takes place over a LAN connection in step S17. If, in step S14, it is determined that the difference is not equal to the constant value X, it is determined that the communication takes place across a WAN connection in step S18. The present invention can be applied to a personal computer on a wireless LAN.

摘要： A content usage control apparatus prevents a content managed by an end user from being illegally used. To prevent a content from being used by an apparatus or user other than an authorized apparatus or user, a content usage control apparatus registers the authorized apparatus or user and determines, before providing the content, whether the content is going to be provided to the authorized apparatus or user. The content usage control apparatus also has the capability of imposing a limitation on rewriting of registration. The above-described capabilities of the content usage control apparatus make it possible to protect copyright of information to be provided. A specific example of the content usage control apparatus is a server which stores contents such as movie contents or music contents, and may be used in a system in which a content is provided in response to a request from a client such as a portable telephone, a TV set, or a personal computer, connected to the server.

摘要： The present invention relates to a telecommunications apparatus and a method, a storage medium, and a program for determining whether or not an other side communicating apparatus is near in a network. In a transmitting apparatus, a transmitting unit transmits a sending-message, and a control unit receives a response message to the sending-message, which includes acknowledgement information based on shared data and transmission information in the sending-message. The transmitting apparatus also includes a first judging unit that judges whether a response time of the acknowledgement message is less than a predetermined time. A receiving apparatus includes a generating unit that generates the acknowledgment information and transmits the response message to the transmitting apparatus.
