Abstract: In order to provide a recording and reproducing device that allows a user to select and manage arbitrary play lists, a unit of management for managing all registered play list information and an upper management hierarchical level are added. The unit of management is adapted to be handled on the same level with unified information that indicates a reproduction range of all AV data. User-defined unified information is adapted to be handled on the added management hierarchical level. The user-defined unified information is formed to allow arbitrary reproduction ranges contained on a lower hierarchical level to be registered.

Abstract: An output control method for controlling copy operation for a digital broadcast program permitted to be recorded for one generation (copy one generation) with an improved operating convenience. A digital content and a plurality of types of copy control information for controlling the copies of the digital content are received, and in accordance with the copy control information, the digital content is output to a plurality of recording media connected through a network. If first information contained in the copy control information received indicates copy generation information to permit copies for one generation and second information contained in the copy control information indicates “limited number of copies permitted” mode permitting a predetermined number of copies, then the digital content is output to only one of the recording media in a state permitting copying up to the predetermined number.

Abstract: A content transmission device for transmitting a digital content to other device connected via a network, including a receiving unit that receives the digital content accompanied with a piece of copy control information indicating a condition of restricting the digital content from being copied, a communication processing unit that transmits and receives the digital content or various data, or control commands to and from the other device, a connection determining unit that determines whether the other device is present on an intra-residential network connected by the content transmission device, and a control unit that controls the receiving unit, the communication processing unit, and the connection determining unit, in which the control unit does not output the digital content received by the receiving unit from the communication processing unit to the other device in a case where the other device is determined not to be installed at an inside of a residence by using the connection determining unit, thereb

Abstract: A method and apparatus is provided for receiving and/or reproducing a digital signal, capable of efficiently recording a compressed, packeted digital signal and inhibiting a copy thereof. An input packet signal is added with a time stamp indicating a relative time of an arrival of the packet, and the packet signals of digital information with the added time stamps are recorded at reduced intervals therebetween. In reproducing, a packet interval adjusting circuit restores the original packet intervals in accordance with the time stamps, and then a time stamp change circuit changes at least one bit of the time stamp and thereafter outputs the digital information.

Abstract: A content transmitter apparatus is provided which decides whether to permit a content receiver apparatus at a content transmission destination to retransmit content to another content receiver apparatus located inside a house and transmits to the content receiver apparatus the content along with an identifier indicating a permission or prohibition of the content retransmission. A content receiver apparatus is also provided which, when it receives encrypted content from the content transmitter apparatus, checks an identifier received together with the content in executing the content retransmission to another content receiver apparatus located outside the house. If the identifier is found to permit the content retransmission, the content receiver apparatus encrypts and retransmits the content to the outside-house content receiver apparatus. If the identifier is found to not permit the content retransmission, the content receiver apparatus does not retransmit the content to the outside of the house.

Abstract: The usability while performing copy control can be enhanced in the case of recording a digital broadcast program for which recording of one generation is permitted (“Copy One Generation”). When an output route in the case of copying digital contents from a first recording apparatus to a second recording apparatus is via LAN, authentication is executed between the first recording apparatus and the second recording apparatus. The capability of a move process with a predetermined copy number of multiple copies being kept is confirmed, and dedicated key information is shared to be used for encryption and decryption of the digital contents moved with the predetermined copy number of multiple copies being kept. Then, the digital contents recorded and managed in the first recording apparatus is added with the information about the predetermined copy number of multiple copies, and transmitted.
