摘要： Before content transmission, the content transmitting device and the content receiving device mutually authenticate each other to verify that the other device respects copyright and rightfully handles content, and then content is encrypted by shared key data and transmitted. It is arranged that in an authentication process, a time from transmission of an authentication request or a time from transmission of an authentication response until arrival of receipt acknowledgement data is measured and only when a measured time is less than a fixed upper-limit value, content is transmitted.

摘要： It is an object of the present invention to protect a copyright of a content by suppressing creation of illegal copies of the content and prevent a content from being transmitted beyond a range of personal use in a process to transmit the content through a wire or wireless LAN. Before transmitting a content from a content transmission apparatus to a content reception apparatus, the content transmission apparatus and the content reception apparatus authenticate each other. In the authentication, a timer measures a time interval between a transmission of an authentication request and a reception of an acknowledgement of a reception of the request or between a transmission of a response to a received authentication request and a reception of an acknowledgement of a reception of the response. If the time interval does not exceed an upper limit, a content encrypted by using a shared key is transmitted from the content transmission apparatus to the content reception apparatus, and the address of the content reception apparatus as well as apparatus information unique to the content reception apparatus are cataloged in the content transmission apparatus. Thus, in order to transmit another content, the content is merely encrypted prior to the transmission without measuring a time interval.

摘要： In transmission of stream data protected for copyright on a bus, transcription of stream data once recorded on a recording apparatus to a medium of another recording apparatus is realized. Authentication is carried out between a stream recording and playback apparatus and another recording apparatus to interchange a key for data scramble. By using this key, data is added with copy control information used when the data is recorded initially and thereafter the data is transmitted. After the data has been recorded on the recording apparatus, the data is deleted from an original recording medium. During transmission of the data, authentication from a different apparatus is rejected to prevent a plurality of copies from being made.

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.

摘要翻译： 本发明提供一种方法和装置，当复制被限制为“一代”时，防止复制成无限数量的存储介质而不受限制，从而保护有关版权所有者的利益。 在本发明中，当将复制的数字信息输出到连接到多个输出电路（315A，315B或72A至72D）的外部设备时，数字信息的外部设备的总数 输出被限制在预定常数内。 特别地，控制电路（311或73）限制连接到多个输出电路的外部设备的认证的数量。 这使得可以在预定常数内限制要输出数字信息的外部设备的总数。

摘要： A copyright of a content is protected by preventing creation of illegal copies of the content and the content is prevented from being transmitted beyond a range of personal use in a process to transmit the content through a LAN. Before transmission of a content, a content transmission apparatus and a content reception apparatus perform a determination of authentication information available in a predetermined command accompanying authentication information, or an authentication determination based on a time until reception of a response to a predetermined command request accompanying predetermined authentication information. If the authentication is unsuccessful, the requested content is not transmitted to the content reception apparatus. With such arrangement, it is possible to effectively protect a copyright when a content is transmitted by way of a network.

摘要： An optical disc player for optically recording the video information or audio information onto a recording medium or optically reproducing the recorded information. The disc player includes a search unit for searching an information track having no signals recorded thereon prior to additionally recording an information signal on the unrecorded track. The search unit has a level detection circuit for detecting the energy value of the light reflected by the recording medium or an RF signal detection circuit for detecting the RF signal component. When the reflected light energy exceeds a predetermined value or the RF signal component is not detected, the search unit regards the track as a track having no signals recorded thereon, the search operation for a track having no signals being terminated and information can be recorded of the track having no signals recorded thereon.
