    摘要: A digital signal recording and reproducing method and apparatus using first, second, third, and fourth information as information to protect a copyright, the first and second information are added to the digital signal, the third information is inputted from the digital interface together with the digital signal, a value of the fourth information is decided from a combination of the first to third information, and the fourth information is recorded onto the recording medium. The first information is information to control a copy restriction of the digital signal, the second information is information to perform a control about whether the signal is protected against the illegal use or not, the third information is information to indicate whether the signal has been encrypted or not, and the fourth information is information to control the copy restriction of the digital signal recorded on the recording medium.

    摘要: An apparatus comprising a transmission system for transmitting an information signal, and a reception system including an information receiving unit for receiving the information signal, and an information recording/reproducing unit for recording/reproducing the received information signal on/from a recording medium. The reception system includes a specific information storage circuit for storing specific information which is assigned peculiarly to the reception system in advance, a specific information donating circuit for adding the specific information to the received information signal or encrypting the received information signal on the basis of the specific information to supply the resulting information signal to the information recording/reproducing unit, and a specific information judgement circuit for receiving an information signal reproduced by the information recording/reproducing unit and verifying the information signal with a condition based on the specific information stored in the specific information storage circuit so that when the condition is satisfied, a signal obtained by deleting the specific information added to the reproduced information signal or by decrypting the encrypted information signal is outputted.

    摘要: The present invention provides a method and an apparatus that, when a copying is limited as “Copy One Generation”, prevent the copying from being made into infinite number of storage media without limitation, and thereby protect the profit of a copyright holder concerned.In the present invention, when outputting digital information whose copying is limited to external appliances connected to plural outputting circuits (315A, 315B, or 72A to 72D), the total number of external appliances to which the digital information is to be outputted is limited within a predetermined constant. In particular, a control circuit (311, or 73) limits the number in which to perform authentications of the external appliances connected to the plural outputting circuits. This makes it possible to limit, within the predetermined constant, the total number of the external appliances to which the digital information is to be outputted.

    摘要: A digital information recording apparatus includes multiple recording circuits for making multiple copies. The apparatus limits the number of copies, however, in accordance with copy information provided within the digital information itself. When the number of copies is reached, if additional copies are to be made, then the source copy is disabled when a new copy is made.
