摘要： In a digital information recording/reproducing apparatus, information recorded on a hard disk with copy restriction thereof is protected from being copied onto other hard disks by means of a PC, etc., to be produced a large number of illegal copies, i.e., infringing a copyright.The information is recorded onto a hard disk drive through encryption thereof, with using an identification being number unique thereto, when it is recorded onto the hard disk. With this, normal reproduction is prevented, since the drive identification number necessary for decryption is different from, even if it is copied onto the other hard disk. Also, a version information of the hard disc is memorized in an information management circuit. When the information is illegally copied onto the other hard disc, the version information is changes; therefore it does not coincide with the version information memorized in the information management circuit. With this, illegal reproduction of the information copied can be prohibited in the reproducing operation.
摘要翻译：在数字信息记录/再现装置中，通过PC等来保护记录在具有其复制限制的硬盘上的信息被保护以被复制到其他硬盘上，以产生大量的非法拷贝，即侵权版权。当通过其加密将信息记录在硬盘驱动器上时，当将其记录到硬盘上时，使用其中唯一的标识。因此，由于解密所需的驱动器识别号码即使被复制到另一个硬盘上也是不同的，所以防止正常再现。此外，硬盘的版本信息被存储在信息管理电路中。当信息被非法复制到另一个硬盘上时，版本信息是变化的; 因此与信息管理电路中存储的版本信息不一致。由此，在再现操作中可以禁止复制的信息的非法再现。

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： 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.
