摘要： To solve the problem inhibiting the copyright protection caused by reason that there are no means for restricting the number of backups to other media, which makes it impossible for a copyright owner to specify the allowable number of backups for the content of “Copy One Generation”, disclosed herein is a digital information recording and reproducing method. The method is so configured that: a first piece of digital information and copy control information of the first piece of digital information is received, wherein the copy control information is for controlling the recording of the first piece of digital information on a recording medium; and when the received copy control information is Copy One Generation indicating that only one generation copy of digital information is allowed, a plurality of the first pieces of digital information are recorded on a first recording medium as the first piece of digital information and a second piece of digital information, wherein the first piece of digital information is different in format or in bit rate from the second piece of digital information.
摘要翻译：为了解决由于没有办法将备份数量限制到其他媒体而导致的版权保护问题，这使得版权所有者不可能为“一代复制”的内容指定允许的备份数量，这里公开的是数字信息记录和再现方法。该方法被配置为：接收第一数字信息的第一数字信息和复制控制信息，其中复制控制信息用于控制在记录介质上记录第一片数字信息; 并且当接收到的复制控制信息是指示仅允许数字信息的仅一代拷贝的一代的复制控制信息时，多个第一数字信息作为第一数字信息被记录在第一记录介质上，而第二片数字信息，其中第一片数字信息的格式或与第二数字信息的位速率不同。

摘要： If content is transmitted/received through a digital signal bus, protection of copyright causes a problem because of no deterioration in quality. Accordingly, authentication is required. The quantity of information to be processed is, however, so large that a long time is required for authentication. Accordingly, both achievement of handling property as in conventional analog connection and protection of copyrighted content without user's awareness become an object. The foregoing object can be achieved by authentication which is executed, for management of copyright, among apparatuses connected to the digital signal bus when the apparatuses are powered on or connected to the digital signal bus or when an input terminal connected to the digital signal bus is selected. The object can be further achieved by an encryption key shared among these apparatuses.
摘要翻译：如果通过数字信号总线发送/接收内容，则由于质量的劣化，版权保护造成问题。因此，需要认证。然而，要处理的信息量如此之大以至于需要长时间的认证。因此，在传统模拟连接中实现处理属性和保护没有用户意识的版权内容成为目的。上述目的可以通过在设备上电或连接到数字信号总线时连接到数字信号总线的设备之间执行的用于管理版权的认证来实现，或者当连接到数字信号总线的输入端子是选择。可以通过这些装置之间共享的加密密钥来进一步实现该目的。

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： A digital signal recording apparatus is disclosed, which is capable of protecting the copyright of the analog input information encoded into a first digital signal in a recording medium. A second digital signal encrypted based on the key information and the input analog signal encrypted based on the key information are converted into a second digital signal and encrypted, and the resulting signal is selectively recorded in a recording medium. The digital signal recording apparatus further comprises a circuit for encrypting the digital signal converted from the input analog signal with a key obtained by a predetermined calculation of the key information according to a scheme similar to the second digital signal protection scheme through a digital interface, and a signal recording circuit for recording the key information and the encrypted digital signal in a recording medium.
